Practice with experts

Using case interview examples is a key part of your interview preparation, but it isn’t enough.

At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.

If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.

Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!

Need of MBA Case Studies

Case i: chemco case.

• ChemCo is a quality leader in the U.K. car batteries market.
• Customer battery purchases in the automobile market are highly seasonal.
• The fork-lift business was added to utilize idle capacity during periods of inactivity.
• This is a low-growth industry (1% annual growth over the last two years)
• Large customers are sophisticated and buy based on price and quality. Smaller customers buy solely on price.
• There is a Spanish competitor in the market who offers low priced batteries of inferior quality.

• GD: Ettiquette
• GD: Content
• Solved Case Studies
• High quality product, but low end customers care more about price than quality
• Mismanaged product diversification in a price sensitive market
• Alternative 1: Establish an Off-Brand for the fork-lift business
• Alternative 2: Educate the customer market about product quality
• Alternative 3: Exit the fork-lift battery business
• Establishing the firm's quality image
• Increase in market share
• Increase in sales
• Cost of the product
• Protect firm's quality image in the automobile industry
• Redesigned product to reduce the cost of manufacture
• Low price to enable it to compete with Spanish producer
• Make use of the quality leadership in car batteries market
• Offer reliability testing, extended warranties etc. to promote quality image
• Set higher prices to extract surplus from these advantages
• A passive strategy, not proactive
• Recommendations: Alternative 1 is recommended in this case. Since the firm operates in an industry which has low growth, hence it can expand market share and sales only by taking the customers from other players. Hence, it needs to tackle the Spanish competitor head-on by aggressively pricing its product. At the same time, launching a low-priced product under the same brand name erodes the high quality image in the car batteries market. Hence, the best option is to go for an off-brand to target the fork-lift customers who are increasingly becoming price sensitive. This will enable the company to ward off the threat in short-term and build its position strongly in the long-term.

Case II: NAKAMURA LACQUER COMPANY

• The Nakamura Lacquer Company: The Nakamura Lacquer Company based in Kyoto, Japan was one of the many small handicraft shops making lacquerware for the daily table use of the Japanese people.
• Mr. Nakamura- the personality: In 1948, a young Mr. Nakamura took over his family business. He saw an opportunity to cater to a new market of America, i.e. GI's of the Occupation Army who had begun to buy lacquer ware as souvenirs. However, he realized that the traditional handicraft methods were inadequate. He was an innovator and introduced simple methods of processing and inspection using machines. Four years later, when the Occupation Army left in 1952, Nakamura employed several thousand men, and produced 500,000 pieces of lacquers tableware each year for the Japanese mass consumer market. The profit from operations was $250,000.
• The Brand: Nakamura named his brand “Chrysanthemum” after the national flower of Japan, which showed his patriotic fervor. The brand became Japan's best known and best selling brand, being synonymous with good quality, middle class and dependability.
• The Market: The market for lacquerware in Japan seems to have matured, with the production steady at 500,000 pieces a year. Nakamura did practically no business outside of Japan. However, early in 1960, when the American interest in Japanese products began to grow, Nakamura received two offers
• The Rose and Crown offer: The first offer was from Mr. Phil Rose, V.P Marketing at the National China Company. They were the largest manufacturer of good quality dinnerware in the U.S., with their “Rose and Crown” brand accounting for almost 30% of total sales. They were willing to give a firm order for three eyes for annual purchases of 400,000 sets of lacquer dinnerware, delivered in Japan and at 5% more than what the Japanese jobbers paid. However, Nakamura would have to forego the Chrysanthemum trademark to “Rose and Crown” and also undertaken to sell lacquer ware to anyone else the U.S. The offer promised returns of $720,000 over three years (with net returns of $83,000), but with little potential for the U.S. market on the Chrysanthemum brand beyond that period.
• The Semmelback offer: The second offer was from Mr. Walter Sammelback of Sammelback, Sammelback and Whittacker, Chicago, the largest supplier of hotel and restaurant supplies in the U.S. They perceived a U.S. market of 600,000 sets a year, expecting it to go up to 2 million in around 5 years. Since the Japanese government did not allow overseas investment, Sammelback was willing to budget $1.5 million. Although the offer implied negative returns of $467,000 over the first five years, the offer had the potential to give a $1 million profit if sales picked up as anticipated.
• Meeting the order: To meet the numbers requirement of the orders, Nakamura would either have to expand capacity or cut down on the domestic market. If he chose to expand capacity, the danger was of idle capacity in case the U.S. market did not respond. If he cut down on the domestic market, the danger was of losing out on a well-established market. Nakamura could also source part of the supply from other vendors. However, this option would not find favor with either of the American buyers since they had approached only Nakamura, realizing that he was the best person to meet the order.
• Decision problem: Whether to accept any of the two offers and if yes, which one of the two and under what terms of conditions?
• To expand into the U.S. market.
• To maintain and build upon their reputation of the “Chrysanthemum” brand
• To increase profit volumes by tapping the U.S. market and as a result, increasing scale of operations.
• To increase its share in the U.S. lacquerware market.
• Profit Maximization criterion: The most important criterion in the long run is profit maximization.
• Risk criterion: Since the demand in the U.S. market is not as much as in Japan.
• Brand identity criterion: Nakamura has painstakingly built up a brand name in Japan. It is desirable for him to compete in the U.S. market under the same brand name
• Flexibility criterion: The chosen option should offer Nakamura flexibility in maneuvering the terms and conditions to his advantage. Additionally, Nakamura should have bargaining power at the time of renewal of the contract.
• Short term returns: Nakamura should receive some returns on the investment he makes on the new offers. However, this criterion may be compromised in favor of profit maximization in the long run.?
• Reject both: React both the offers and concentrate on the domestic market
• Accept RC offer: Accept the Rose and Crown offer and supply the offer by cutting down on supplies to the domestic market or through capacity expansion or both
• Accept SSW: offer; accept the SSW offer and meet it through cutting down on supply to the domestic market or through capacity expansion or both. Negotiate term of supply.
• Reject both: This option would not meet the primary criterion of profit maximization. Further, the objective of growth would also not be met. Hence, this option is rejected.
• Accept RC offer: The RC offer would assure net returns of $283,000 over the next three yeas. It also assures regular returns of $240,000 per year. However, Nakamura would have no presence in the U.S. with its Chrysanthemum brand name The RC offer would entail capacity expansion, as it would not be possible to siphon of 275,000 pieces from the domestic market over three years without adversely affecting operations there. At the end of three years, Nakamura would have little bargaining power with RC as it would have an excess capacity of 275,000 pieces and excess labor which it would want to utilize. In this sense the offer is risky. Further, the offer is not flexible. Long-term profit maximization is uncertain in this case a condition that can be controlled in the SSW offer. Hence, this offer is rejected.
• Accept SSW offer: The SSW offer does not assure a firm order or any returns for the period of contract. Although, in its present form the offer is risky if the market in the U.S. does not pick up as expected, the offer is flexible. If Nakamura were to exhibit caution initially by supplying only 300,000 instead of the anticipated 600,000 pieces, it could siphon off the 175,000 required from the domestic market. If demand exists in the U.S., the capacity can be expanded. With this offer, risk is minimized. Further, it would be competing on its own brand name. Distribution would be taken care of and long-term profit maximization criterion would be satisfied as this option has the potential of $1 million in profits per year. At the time of renewal of the contract, Nakamura would have immense bargaining power.
• Negotiate terms of offer with SSW: The terms would be that NLC would supply 300,000 pieces in the first year. If market demand exists, NLC should expand capacity to provide the expected demand.
• Action Plan: In the first phase, NLC would supply SSW with 300,000 pieces. 125,000 of these would be obtained by utilizing excess capacity, while the remaining would be obtained from the domestic market. If the expected demand for lacquer ware exists in the U.S., NLC would expand capacity to meet the expected demand. The debt incurred would be paid off by the fifth year.
• Contingency Plan:  In case the demand is not as expected in the first year, NLC should not service the U.S. market and instead concentrate on increasing penetration in the domestic market.

What are Consulting Casebooks?

Consulting casebooks are documents that MBA consulting clubs put together to help their members prepare for consulting case interviews. Consulting casebooks provide some case interview strategies and tips, but they mostly contain case interview practice cases.

While consulting casebooks contain tons of practice cases, there is quite a bit of variety in the sources and formats of these cases.

Some practice cases are taken from actual consulting interviews given by consulting firms. These are the best types of cases to practice with because they closely simulate the length and difficulty of an actual case interview. Other practice cases may be written by the consulting club’s officers. These cases are less realistic, but can still offer great practice.

The formats of the practice cases in consulting casebooks also vary significantly.

Some practice cases are written in a question and answer format. This type of format makes it easy to practice the case by yourself, without a case partner. Other practices cases are written in a dialogue format. These cases are better for practicing with a case interview partner.

How do I use Casebooks to Practice Case Interviews?

How you should use consulting casebooks depends on whether you are practicing cases by yourself or practicing cases with a case partner.

Practicing Cases by Yourself

If you are trying to practice cases by yourself, you will need to find cases that are written in a question and answer format. Only in this format can you read the question, answer it, and then move onto the next question without getting any case spoilers.

To practice cases by yourself, read the case background. Then, summarize the case information out loud, verify the objective to yourself, and then ask clarifying questions out loud.

You likely won’t be able to answer any questions that you have by yourself, but talking to yourself out loud is good practice because it simulates what you would do in a real case interview.

Afterwards, take a few minutes to write out your case interview framework. Treat this like a real case interview, so don’t give yourself unlimited time to think about how you would structure your approach. When you have your framework written out, talk through it like you are explaining it to an interviewer.

Next, move onto the first case question. For each case question, talk through your thinking out loud as if you were in a real interview. If there is math involved, make sure you talk through your calculations out loud.

Once you have finished answering each case question, provide your final recommendation out loud. Make sure to suggest potential next steps.

Now that you have finished the case, you can review your answers and compare them to the sample answers. Try to identify areas of improvement or things that you could have done better.

For a comprehensive guide on how to practice case interviews by yourself, without a case partner, read this article .

Practicing Cases with a Case Partner

If you are practicing with a case partner, decide who is going to be giving the case and who is going to be receiving the case.

If you are giving the case, read the entire case information carefully. It may be helpful to read through everything twice so that you are familiar with all of the information and can answer any question that your partner asks you to clarify.

As the person giving the case, you need to be the case expert.

You should become familiar with the overall direction of the case. In other words, you should know what the major questions of the case are and what the major areas of investigation are. This will help you run the mock case interview more smoothly.  

Depending on whether you want the case interview to be interviewer-led or candidate-led, you will need to decide how much you want to steer the direction of the case.

If your partner gets stuck and is taking a long time, you may need to step in and provide suggestions or hints. If your partner is proceeding down a wrong direction, you will need to direct them towards the right direction.

Caveats to Using MBA Consulting Casebooks

In general, MBA consulting casebooks are great resources because they are free and provide tons of practice cases to hone your case interview skills. However, there are several caveats that you should be aware of.

1. Similarity to Real Case Interviews

Some cases in MBA consulting casebooks are not representative of actual case interviews because they are written by consulting club officers instead of interviewers from consulting firms.

For example, some cases may be too short or too long in length. Some cases could also be too technical or may require you to have specialized knowledge. If you come across a case that is way too complicated or way too simple, keep in mind that the case may not be representative of an actual case interview.

2. Quality of Sample Answers

While consulting casebooks provide sample solutions, these answers are often not the best or highest quality answers. If you use the answers in casebooks as your benchmark for what a great answer looks like, you may not be learning the best way to answer case interview questions.

3. Ease of Use

Consulting casebooks are all written in different formats and by different people. Therefore, it can be challenging to find cases that you can consistently use to practice cases by yourself or with a partner.

Case information may be written in an unorganized way. The main questions of the case may be hidden in the case background information or in the answers. You’ll have to learn the best way to read and digest each case in each casebook.

Introduction to MBA Case Interviews

Case interviews have become an integral part of the MBA admissions process, testing a candidate’s analytical abilities, problem-solving skills, and interpersonal aptitude. The essence of a case interview lies in the presentation of a business problem or scenario, and the task for the candidate is to analyze it, offer solutions, and justify their recommendations. Whether you’re looking at some challenging mba case study examples or diving headfirst into the process , thorough preparation is key.

Key Tips for Effective MBA Case Interview Preparation

Improving analytical skills for case interviews.

Analytical prowess is indispensable when navigating the intricacies of case interviews. Here’s how you can sharpen your analytical skills:

• Practice Regularly: The age-old saying, “Practice makes perfect,” holds in this context. Delve into as many MBA case interview preparation tips and examples as you can find. The more cases you solve, the better you’ll get at swiftly identifying the crux of a problem.
• Diversify Your Case Pool: Don’t just stick to one kind of case. From market sizing to operational problems, ensure you cover a spectrum.

Common Pitfalls to Avoid

Every candidate is prone to certain errors during their interview preparations. Here are some to watch out for:

• Overcomplicating Analysis: Avoid getting bogged down in unnecessary details. While deep dives are great, they shouldn’t sidetrack you from the main issue.
• Losing Structure: A structured approach is paramount. Outline your thought process before diving into problem-solving to ensure you address all key areas.

The Role of Industry Knowledge

While the primary aim of the case interview isn’t to test industry knowledge, being acquainted with sector-specific nuances can give you an edge. Prioritize high-impact industries like tech, finance, and healthcare. Dive into MBA applications to understand the most sought-after industries.

Diverse Case Types and What to Expect

Each case interview can be a unique experience based on the type:

• Market Sizing Cases: These require you to estimate the size of a particular market or segment. For instance, estimating the market for electric cars in Europe.
• Business Strategy Cases: Here, you might be tasked with devising a growth strategy for a stagnant company.
• Operational Cases: These cases can revolve around improving the efficiency of certain business processes.
• Merger & Acquisition Cases: Involve analyzing whether a company should acquire another, merge, or perhaps even divest a part of its operations.

Breaking Down the Case Analysis for MBA Interviews

The essence of a successful case interview lies in a structured analysis. This means dissecting the problem, identifying key issues, and arranging them in a logical manner. Lean into analytical skill development for MBA interviews to refine this approach. Remember, every case has hidden traps. Your job is to unearth them, address them, and build a compelling solution.

Crafting Comprehensive Answers to MBA Case Study Questions

Once you’ve analyzed the case, presenting your findings is crucial. Here’s a guideline:

• Structuring Your Response: Begin with a brief summary, delve into the core of the problem, present your recommendations, and then offer a conclusion.
• Incorporate Data: Use qualitative and quantitative data to substantiate your arguments. If a company’s sales are falling, use percentage drops, and figures to highlight it.
• Provide Actionable Recommendations: Merely identifying problems won’t suffice. Offer solutions that are actionable and feasible.

Case Interview Example:

A leading manufacturer of sports shoes is facing declining sales in Europe. The CEO wants to understand the reasons behind this drop and strategies to turn the situation around.

Approaching the Case:

• Understand the Problem:
• Clarify any doubts regarding the case.
• Ask questions like: How significant is the sales decline? Over what period did this decline happen? Are specific segments of the market affected more than others?
• Structure the Problem: Break down the larger problem into smaller segments you can analyze.
• Market-related issues: Is the whole sports shoe market in decline or just our brand?
• Company-specific issues: Product quality, marketing effectiveness, distribution channel issues, etc.
• External factors: Regulatory issues, economic downturn, etc.
• Hypothesize:
• Based on the data provided and common business sense, hypothesize potential reasons for the decline. For example, “There might be new entrants in the market offering products at a cheaper rate” or “There might be a shift in consumer preferences.”
• Analyze the Problem:
• Market Research: Look into market trends. Are consumers buying more of a particular type of shoe (like sustainable shoes)?
• Company Data: Analyze the company’s sales data, customer feedback, and product lineup.
• Competitive Analysis: How are competitors faring in the same period? Are they facing declines as well?
• Conclude & Recommend:
• Summarize findings: “The sales decline is due to a combination of increasing competition from sustainable shoe brands and ineffective marketing campaigns.”
• Offer actionable recommendations: “Introduce a new line of eco-friendly shoes and revamp the marketing strategy to target the environmentally conscious audience.”
• Feedback Loop:
• Be prepared to answer follow-up questions or delve deeper into specific areas. If the interviewer provides new information, incorporate it into your analysis.

Remember, in a case interview, the journey and approach to the solution can be as important, if not more so, than the solution itself. Interviewers are keen to understand your thought process, analytical skills, and problem-solving approach.

In summary, MBA case interviews can seem daunting, but with meticulous preparation and a structured approach, they are very navigable. Dive deep into MBA case study examples, capitalize on all the MBA case interview preparation tips, and refine your analytical skills. Remember, every interview is a learning opportunity. Whether you ace it or not, the experience will be invaluable in your journey towards an MBA and beyond.

The Complete Guide to a Management Consulting Case Study Interview

Candidates attempting to launch a career in management consulting by applying for positions with firms like McKinsey, Boston Consulting Group (BCG) and Deloitte are waiting nervously for that invitation to interview. And, increasingly, management consulting position interviews with employers like these include a case study component. Adequately preparing for these case study interviews is a key step in the recruitment process.

This introduction to and overview of the case interview process from the experts at The MBA Exchange can help you nail your management consulting case interview. We’ve got all the examples, samples, explainers and tips you need to answer case interview questions with confidence and land your targeted management consulting position.

Serious management consulting candidates need to prepare with care for case interviews, ideally working with a partner or other consulting field expert. 

What is a Case Interview?

Case study interviews provide recruiters from consulting companies with a window into your analytical problem-solving capabilities. These skills that key for any management consulting career . And it’s difficult to show your ability to work on dynamic issues without a “live test,” so to speak. That’s what case study questions are for!

Case study questions ask you to come up with practical solutions to real-world business problems, grounding your answer in hard data, logical reasoning and effective communication. Case interviews are less about demonstrating correct knowledge, or your ability to hit to a “right” answer, than showing off your ability to reason on the fly.

What is the focus and format of the case interview?

The form of case interviews can vary. You might face a stand-alone interview with a partner, or case study questions may be part of an interview that also includes more traditional interview questions designed to gauge “fit.” Case interview questions can vary dramatically from applicant to applicant, so it’s not worth much of your time to try to guess or anticipate them. 

How long is a case interview? Case study interviews usually last about 45 minutes. Some companies may send you the case question and some data 24 hours in advance for you to study. Others will present the case at the start of the interview. You will be expected to ask questions to elicit more information during the interview, and use that information to resolve the problem with specific recommendations.

What is a quantitative case interview?

If you plan to apply for positions with firms like McKinsey, Bain or BCG , you should be prepared for quantitative case study questions and answers. 

Quantitative case interviews focus on your mathematical and logical problem-solving capabilities, a must for our data-driven reality. Often, quantitative case interviews form a core element of the management consulting recruitment process. You might also encounter quantitative case study interview questions in interviews for positions in general management, marketing or even engineering.

Quantitative interview questions reveal the key strengths that you as a candidate will need to become a successful consultant. Here are some examples of questions from different case interview question categories:

• Market sizing: “Estimate the total industry-wide sales of bicycles in the US”
• Revenue estimate: “Estimate annual sales for Starbucks retail stores in the US”
• Breakeven: “A running shoe manufacturer sells shoes for $100 a pair. To produce each pair, the company spends $10 in material and $5 in labor. They have $1M in monthly operating costs. If they sell 30,000 pairs a month, what is their monthly profit?”
• Price elasticity: “The price of a one-way ticket from Seattle to New York is $400. Should JetBlue raise their price to $450?”
• Lifetime value: “What is the customer lifetime value of a Visa card holder over the next three years?”

You need to be prepared to field questions like these, no matter the twists and turns your interview takes! Remember to demonstrate mathematical dexterity: We’re used to doing math with calculators and designing and running complex data analysis algorithms. As a result, we don’t have as much experience doing math by hand. Often, a quick back-of-the-envelope analysis is needed to test that you are on the right path. Quantitative interviews test your ability to manipulate numbers manually at speed. 

What Are Top Consulting Companies Really Looking for?

The case study is not meant to test your domain knowledge or your ability to get to a “right” answer. Instead, what companies will look for is:

• Problem-solving abilities – what approach you take to start addressing the question presented in the case study. Today’s business world has many new and ambiguous problems. Consultants need to be able to tackle unfamiliar challenges with incomplete information and devise a logical framework for setting a course of action. Can you?
• Analytical and creative thinking: What role does creativity play? It informs how you attack the problem, the kinds of probing questions that you ask, the connection you forge with the interviewer and the conclusions you present at the close of the case. Your creativity will certainly set you apart from the rest.
• Presentation of qualitative and/or quantitative data or evidence and logic to support your analysis and recommendations
• Communication skills: Work gets done by teams. To persuade team members and leaders to your point of view as a consultant, you must be able to convince others with logical, objective arguments backed by numbers. Ability to ask insightful questions as well as answer follow-up questions
• Demeanor and poise: Good consultants are calm and inspire confidence. Poised individuals communicate with an approach that is balanced, not emotional. That balanced approach is based on a strategy of sound logic and hard numbers. If you can show these key qualities during your case interview, you’ll be well on your way to management consulting success.

In a case interview, the consultant is looking to see how the candidate will attack the problem. Will they grasp the main question that needs to be solved? Will they ask the pertinent questions to get the relevant information needed to come up with an answer? Will they develop a logical solution based on the evidence? 

In addition to solving the problem, or “cracking the case,” the intangibles in the situation also matter. Does the candidate walk through their logic clearly? Are they comfortable doing calculations in their head? How do they present themself? Are they confident and positive? Are they building rapport with the consultant? 

Case Study Interview Examples

Check out these examples of the types of case interview questions you can expect from major management consulting firms. How well would you do, if you had to craft a response on the spot?

“You are a product manager at a well-established ride-sharing company operating in a highly competitive market. Recently, you read an article in the “Weekend Journal” section of the Wall Street Journal that examines how senior citizens engage with the digital economy. The article describes how a team of researchers from a reputable US university conducted focus groups with senior citizens who frequently use ride-sharing apps because they are no longer able to drive. One of the findings was that seniors are frustrated by how quickly their cars arrived – often in under five minutes – after the ride was booked. With this information in mind, describe what recommendations you would make to your ride-sharing company (if any).”

“The Weston Group is a Canadian retailer that is facing limited growth. The CEO has proposed creating a new tablet, the ‘Hudl’, that will be affordable and target the 75% market in Canada that does not have tablets. Do you think that this is an innovative idea? Should Weston Group pursue this venture?”

“Assume you have taken over Nokia as CEO. Following the major sale to Microsoft, what steps would you take to ensure the company’s profitability and future survival?”

Case interviews are not a cause for panic or concern: you should welcome them as an open-ended opportunity to demonstrate your understanding of, and comfort with, analytical problem-solving. Rather than a “correct” answer, the interviewer is seeking to understand how you think and communicate.

How to Answer Consulting Case Interview Questions

The key to success in case interviews is to think logically and follow a linear thought process, while still leaving space for creativity in your final response. Here is a general format for you to follow:

• Listen very carefully and take notes on the case as presented by your interviewer. Pay attention to subtle cues and guidance that could help you justify your proposed solution.
• Ask for clarification if you don’t understand something significant. Your questions will be “on the record” so be articulate and thoughtful. Pose a “framing” question to elicit more information than you were given upfront. For instance, if you are given a case about a venture capital firm considering an investment in a startup, you can ask: “Does this VC have other portfolio companies in the same industry and therefore might be planning a roll-up of multiple companies?”
• Paraphrase the situation and the key issues/problems/opportunities. For instance, “Company X is losing market share despite a growing market for its products. The CEO must decide whether to reduce price to increase demand, differentiate the offerings to justify a higher price or seek a merger partner to add scale and reduce manufacturing cost.”
• Walk through the steps of your analysis clearly. Make simplifying assumptions as necessary. You can use paper and pencil to do your calculations, and you can share any simple illustrations, like a 2×2 matrix, that illustrates your problem-solving process.
• Develop your potential solution and test your answer to make sure it is achievable. For example, are your sales projections reasonable given the size of the total market and current growth rates? Are there additional criteria that need to be checked to reach success? For example, does the company have an adequate supply chain to sustain its projected growth? Look for disconfirming evidence to ensure your solution is robust.
• Confidently summarize the problem that was posed and your hypothetical solution, identifying three convincing support points for your solution. For instance, if you think Company X should seek a merger partner, your support would be: the market is already price sensitive, there is excessive supply available, and other companies with more efficient factories are also feeling pain.” Three points of convincing support should shore up your suggested solution, giving you a solid tripod of elegant evidentiary reasoning.

Case Interview Prep for Consulting

You don’t need to panic when it comes to case interview preparation. You can’t control when you’ll be invited to consulting interviews with companies like BCG and McKinsey, or who you’ll interview with when the time comes. You can’t even control what the subject matter of the case will be. But you can control your ability to perform well during the case with your prep for case interviews.

Preparing on your own

Candidates who are serious about pursuing a career in consulting should set aside a significant portion of their time to practice their case interviewing skills. Did you know that the best practice case interview questions actually often come from business news articles in major publications like the Wall Street Journal or The New York Times? Find an article about a company that is facing a difficult business decision, and describe for yourself what and how you would address it as the CEO. There you go, that’s case interview prep!

At a minimum, you should prepare yourself for success by committing to practicing your case techniques for several weeks before your interview. Doing 50–70 cases is common. However, it is just as important to practice the right way if you want to achieve your management consulting career goals .

Welcome these open-ended opportunities to demonstrate your understanding of, and comfort with, analytical problem-solving. Solving cases is a skill that can be learned and developed. Just as you would have better chances of scoring well on the SAT, GRE or GMAT by studying the format of the test, doing practice tests and developing a strategic approach, you can improve your case-solving skills during your consulting case prep.

Preparing with others

The best practice is doing cases with someone who can give you targeted feedback not only on the obvious factors such as correct case math, appropriate frameworks, and logical structure, but also on the intangible components of the evaluation, such as your communication skills and client-facing presence.

It’s a good idea to look for some guidance and support from people familiar with the industry as you build your business case prep plan. Practicing written cases with your peers helps you internalize the logic for cracking cases. However, a peer will not know what the evaluation criteria are for top tier firms and won’t be able to evaluate how you are performing versus your competition. 

For a realistic assessment of your strengths and weaknesses, you should do some case interview practice with someone from the industry — either an industry contact who is willing to practice with you, or a firm like the Career Consulting Academy.

The more you practice, the more comfortable you will feel and the better you will do on interview day. In addition to the guidance provided above, top management consulting firms such as McKinsey, Bain and BCG feature valuable suggestions and sample case interviews that you can use to prepare. In order to ensure that you are practicing the right skills, look for some guidance and support from people familiar with the industry.

Strategic preparation for consulting case interviews

A strategic approach to preparing for case interviews involves:

• Working through cases out loud with an expert coach
• Receiving constructive feedback on your strengths and weaknesses
• Developing a plan on how to improve your case interview skills
• Building skills and confidence in the case interview process

Understand and internalize key frameworks, don’t try to memorize them. A common mistake is the desire to remember the solution to every single case in every single industry. Clearly, that’s impossible. Understanding how case solutions are structured and internalizing the key logical steps to take to solving a case is much more effective than memorizing fifteen frameworks and trying to think through what framework matches the problem you’ve been presented with during the interview.

Get comfortable with oral math. Nothing is more off-putting than someone who cannot perform simple multiplication, division, taking percentages, etc. out loud. Wean yourself off of your calculator and learn how to make meaningful estimates that simplify your calculations.

Remember that half of the evaluation will be on intangibles — your executive presence, your skill at building rapport with the interviewer, and your oral communication skills. If you think it’s all about the “right answer,” you’re wrong!

With these steps, you can step into case interview or qualitative case interview situations with confidence and mental clarity, providing instant evidence of how competently you can handle the challenges of a top-tier management consulting career at your consulting interviews and impressing potential employers when it matters most.

Case interview sample question and answer tips – Mergers & Acquisitions

Instead of creating one in-house, we invited Marc Cosentino, the world’s foremost authority on case interviewing, to write a sample case interview question exclusively for MBA Crystal Ball readers.

Marc has twenty seven years of experience with case questions, has written over a 100 cases and trained over 150,000 students and alumni. His authoritative book ‘Case in Point’ was called the MBA Bible by the Wall Street Journal.  

Case interview example with sample questions and answers

How to tackle a mergers & acquisitions case, by marc cosentino.

  While there are a variety of cases an interviewer can give you, one of the most popular is a merger and acquisition case. A case interview example might be:  

Interviewer: Our client company G is a high-end maker/manufacturer of luxury goods. It is unable to keep up with demand for alligator-skin products, hand bags, wallets, belts and briefcases. Not only is it having a hard time getting the alligator, it has seen the price of alligator double in the last nine months squeezing otherwise fat margins. The client is considering buying company H, a Louisiana-based company that sources, tans and processes alligator leather. What do they need to take into consideration?

  The student should first summarize the question, streamline it, not repeat it word for word. The student should also ask a clarifying question or two. One good clarifying question in a M&A case is “Why do they want to buy the company?” Very few students ever ask why.  

Student: Our client, company G, is considering acquiring company H and we’ve been tasked to determine whether this is a good idea. I have a couple of clarifying questions. Why do they want to buy H?

Interviewer: Why do you think?

  It’s not uncommon for the interviewer to throw that questions right back at you – so be prepared. Learn some common reasons why one company might buy another.  

Student: I can think of a number of reasons. Guaranteed uninterrupted source of alligator leather. Reduced alligator costs through lower margins and synergies. Pre-empt the competition from buying H and limiting our source, and maybe to diversify holdings.

  If you memorize reasons to acquire before-hand you won’t have to stop and think about it and you’ll sound confident and professional. I don’t care who is giving the case, McKinsey, Amazon, Pepsi or Bain they all look for the same four things: structure of thought, confidence level, communication skills and creativity.   The most important of the four is structure of thought. Each structure should be crafted to the individual case. Be cautious of books that sell you on the fact that one structure fits all cases. These are often just glorified cookie-cutter approaches that stifle original thought, create pedestrian answers that lack tactical or strategic brilliance, and make it harder to set yourself apart from the competition.  

Student: I’d like to break this down into a few buckets. Company G, the luxury industry, company H, acquisition costs and risks, and exit strategy.

  The student should turn their paper toward the interviewer and walk the interviewer through each bucket, touching on the headings first.  

  After explaining your structure, state your initial hypothesis. You can state “My hypothesis is…” or “My thoughts are that G should buy H to control costs and maintain fat margins.”It is important to remember to state a hypothesis.  

Interviewer: Okay, good. This is what I know about G. (Hands the student a small chart).

Student: Thanks. (Does some quick calculations) It looks like revenues increased 2%, and its profit margin stayed constant at around 15%. How does that compare to the industry overall?

  In every case there will be math. The most common math is percentages. You need to be able to do them on the fly – quickly in your head. Consultants like to put things in perspective which is why they always do two things: they quantify related numbers as percentages and ask for trends. If you don’t do those two things automatically, you need to start from this day on.   At the end of the case the interviewer will ask you for a recommendation. Lead with the recommendation, state a clear “yes” or “no”. Do not say “I think they…” be definitive. Your M&A recommendation should include; yes or no, why, the risks involved (in order of severity) and the next steps, both for the short-term and long-term.  

Student: Yes, G should buy H if the price is acceptable. Why? to ensure an uninterrupted flow of alligator and to control costs. The risks are that the bottom falls out of the alligator market or it becomes less fashionable. Some next steps: let H be H and don’t try to integrate the two companies. The cultures are too different. Continue to supply all customers at a small price increase because the margins on alligator is greater than on alligator products.

  Once you give your recommendation there is a good chance, that regardless of your decision, the interviewer will take the other side of the argument and say “Let me tell you why you are wrong.”

The interviewer is looking for you to defend your answer without getting defensive, make a persuasive argument while keeping your confidence high.   About the author: Marc Cosentino is the president of CaseQuestions.com and the former Associate Director of Career Services at Harvard for 18 years.

I Have scored 700 in GMAT and have 3 years of work experience with 2 years in startup as head of marketing and CEO of its child company with GPA of 4 /4 . Can you give me an idea whether i have a chance of admission in Rotman Canada with scholarship.

hi sir, i am an english literature student.i wan’t to do MBA.which will be easier and best to me after my BA?

@Kumar: It’s tough to answer such questions. Here’s why: https://www.mbacrystalball.com/blog/2011/10/26/how-not-to-select-business-schools-mba-application-don%e2%80%99ts/

But you do have a decent profile. So, go ahead and put in your best shot. Make sure you also target other bschools in Canada, since Rotman is so competitive. Always good to have a backup option.

@Vasundhara: You’ll have to share much more about yourself (like your work experience, career goals, test scores) for us to provide any helpful response.

1. The key to landing your consulting job.

Case interviews - where you are asked to solve a business case study under scrutiny - are the core of the selection process right across McKinsey, Bain and BCG (the “MBB” firms). This interview format is also used pretty much universally across other high-end consultancies; including LEK, Kearney, Oliver Wyman and the consulting wings of the “Big Four”.

If you want to land a job at any of these firms, you will have to ace multiple case interviews.

It is increasingly likely that you will also have to solve online cases given by chatbots etc. You might need to pass these before making it to interview or be asked to sit them alongside first round interviews.

Importantly, case studies aren’t something you can just wing . Firms explicitly expect you to have thoroughly prepared and many of your competitors on interview day will have been prepping for months.

Don’t worry though - MCC is here to help!

This article will take you through a full overview of everything you’ll need to know to do well, linking to more detailed articles and resources at each stage to let you really drill down into the details.

As well as traditional case interviews, we’ll also attend to the new formats in which cases are being delivered and otherwise make sure you’re up to speed with recent trends in this overall part of consulting recruitment.

Before we can figure out how to prepare for a case interview, though, we will first have to properly understand in detail what exactly you are up against. What format does a standard consulting case interview take? What is expected of you? How will you be assessed?

Let's dive right in and find out!

2. What is a case interview?

Before we can hope to tackle a case interview, we have to understand what one is.

In short, a case interview simulates real consulting work by having you solve a business case study in conversation with your interviewer.

This case study will be a business problem where you have to advise a client - that is, an imaginary business or similar organisation in need of guidance.

You must help this client solve a problem and/or make a decision. This requires you to analyse the information you are given about that client organisation and figure out a final recommendation for what they should do next.

Business problems in general obviously vary in difficulty. Some are quite straightforward and can be addressed with fairly standard solutions. However, consulting firms exist precisely to solve the tough issues that businesses have failed to deal with internally - and so consultants will typically work on complex, idiosyncratic problems requiring novel solutions.

Some examples of case study questions might be:

• How much would you pay for a banking licence in Ghana?
• Estimate the potential value of the electric vehicle market in Germany
• How much gas storage capacity should a UK domestic energy supplier build?

Consulting firms need the brightest minds they can find to put to work on these important, difficult projects. You can expect the case studies you have to solve in interview, then, to echo the unique, complicated problems consultancies deal with every day. As we’ll explain here, this means that you need to be ready to think outside the box to figure out genuinely novel solutions.

2.1. What skills do case interviews assess?

Reliably impressing your interviewers means knowing what they are looking for. This means understanding the skills you are being assessed against in some detail.

Overall, it’s important always to remember that, with case studies, there are no strict right or wrong answers. What really matters is how you think problems through, how confident you are with your conclusions and how quick you are with the back of the envelope arithmetic.

The objective of this kind of interview isn’t to get to one particular solution, but to assess your skillset. This is even true of modern online cases, where sophisticated AI algorithms score how you work as well as the solutions you generate.

If you visit McKinsey , Bain and BCG web pages on case interviews, you will find that the three firms look for very similar traits, and the same will be true of other top consultancies.

Broadly speaking, your interviewer will be evaluating you across five key areas:

2.1.1.One: Probing mind

Showing intellectual curiosity by asking relevant and insightful questions that demonstrate critical thinking and a proactive nature. For instance, if we are told that revenues for a leading supermarket chain have been declining over the last ten years, a successful candidate would ask:

“ We know revenues have declined. This could be due to price or volume. Do we know how they changed over the same period? ”

This is as opposed to a laundry list of questions like:

• Did customers change their preferences?
• Which segment has shown the decline in volume?
• Is there a price war in the industry?

2.1.2. Two: Structure

Structure in this context means structuring a problem. This, in turn, means creating a framework - that is, a series of clear, sequential steps in order to get to a solution.

As with the case interview in general, the focus with case study structures isn’t on reaching a solution, but on how you get there.

This is the trickiest part of the case interview and the single most common reason candidates fail.

We discuss how to properly structure a case in more detail in section three. In terms of what your interviewer is looking for at high level, though, key pieces of your structure should be:

• Proper understanding of the objective of the case - Ask yourself: "What is the single crucial piece of advice that the client absolutely needs?"
• Identification of the drivers - Ask yourself: "What are the key forces that play a role in defining the outcome?"

Our Problem Driven Structure method, discussed in section three, bakes this approach in at a fundamental level. This is as opposed to the framework-based approach you will find in older case-solving

Focus on going through memorised sequences of steps too-often means failing to develop a full understanding of the case and the real key drivers.

At this link, we run through a case to illustrate the difference between a standard framework-based approach and our Problem Driven Structure method.

2.1.3. Three: Problem Solving

You’ll be tested on your ability to identify problems and drivers, isolate causes and effects, demonstrate creativity and prioritise issues. In particular, the interviewer will look for the following skills:

• Prioritisation - Can you distinguish relevant and irrelevant facts?
• Connecting the dots - Can you connect new facts and evidence to the big picture?
• Establishing conclusions - Can you establish correct conclusions without rushing to inferences not supported by evidence?

2.1.4. Four: Numerical Agility

In case interviews, you are expected to be quick and confident with both precise and approximated numbers. This translates to:

• Performing simple calculations quickly - Essential to solve cases quickly and impress clients with quick estimates and preliminary conclusions.
• Analysing data - Extract data from graphs and charts, elaborate and draw insightful conclusions.
• Solving business problems - Translate a real world case to a mathematical problem and solve it.

Our article on consulting math is a great resource here, though the extensive math content in our MCC Academy is the best and most comprehensive material available.

2.1.5. Five: Communication

Real consulting work isn’t just about the raw analysis to come up with a recommendation - this then needs to be sold to the client as the right course of action.

Similarly, in a case interview, you must be able to turn your answer into a compelling recommendation. This is just as essential to impressing your interviewer as your structure and analysis.

Consultants already comment on how difficult it is to find candidates with the right communication skills. Add to this the current direction of travel, where AI will be able to automate more and more of the routine analytic side of consulting, and communication becomes a bigger and bigger part of what consultants are being paid for.

So, how do you make sure that your recommendations are relevant, smart, and engaging? The answer is to master what is known as CEO-level communication .

This art of speaking like a CEO can be quite challenging, as it often involves presenting information in effectively the opposite way to how you might normally.

To get it right, there are three key areas to focus on in your communications:

• Top down : A CEO wants to hear the key message first. They will only ask for more details if they think that will actually be useful. Always consider what is absolutely critical for the CEO to know, and start with that. You can read more in our article on the Pyramid Principle .
• Concise : This is not the time for "boiling the ocean" or listing an endless number possible solutions. CEOs, and thus consultants, want a structured, quick and concise recommendation for their business problem, that they can implement immediately.
• Fact-based : Consultants share CEOs' hatred of opinions based on gut feel rather than facts. They want recommendations based on facts to make sure they are actually in control. Always go on to back up your conclusions with the relevant facts.

2.2. where are case interviews in the consulting selection process.

Not everyone who applies to a consulting firm will have a case interview - far from it!

In fact, case interviews are pretty expensive and inconvenient for firms to host, requiring them to take consultants off active projects and even fly them back to the office from location for in-person interviews. Ideally, firms want to cut costs and save time by narrowing down the candidate pool as much as possible before any live interviews.

As such, there are some hoops to jump through before you make it to interview rounds.

Firms will typically eliminate as much as 80% of the applicant pool before interviews start. For most firms, 50%+ of applicants might be cut based on resumes, before a similar cut is made on those remaining based on aptitude tests. McKinsey currently gives their Solve assessment to most applicants, but will use their resulting test scores alongside resumes to cut 70%+ of the candidate pool before interviews.

You'll need to be on top of your game to get as far as an interview with a top firm. Getting through the resume screen and any aptitude tests is an achievement in itself!

For readers not yet embroiled in the selection process themselves, let’s put case interviews in context and take a quick look at each stage in turn. Importantly, note that you might also be asked to solve case studies outside interviews as well…

2.2.1. Application screen

It’s sometimes easy to forget that such a large cut is made at the application stage. At larger firms, this will mean your resume and cover letter is looked at by some combination of AI tools, recruitment staff and junior consulting staff (often someone from your own university).

Only the best applications will be passed to later stages, so make sure to check out our free resume and cover letter guides, and potentially get help with editing , to give yourself the best chance possible.

2.2.2. Aptitude tests and online cases

This part of the selection process has been changing quickly in recent years and is increasingly beginning to blur into the traditionally separate case interview rounds.

In the past, GMAT or PST style tests were the norm. Firms then used increasingly sophisticated and often gamified aptitude tests, like the Pymetrics test currently used by several firms, including BCG and Bain, and the original version of McKinsey’s Solve assessment (then branded as the Problem Solving Game).

Now, though, there is a move towards delivering relatively sophisticated case studies online. For example, McKinsey has replaced half the old Solve assessment with an online case. BCG’s Casey chatbot case now directly replaces a live first round case interview, and in the new era of AI chatbots, we expect these online cases to quickly become more realistic and increasingly start to relieve firms of some of the costs of live interviews.

Our consultants collectively reckon that, over time, 50% of case interviews are likely to be replaced with these kinds of cases. We give some specific advice for online cases in section four. However, the important thing to note is that these are still just simulations of traditional case interviews - you still need to learn how to solve cases in precisely the same way, and your prep will largely remain the same.

2.2.3. Rounds of Interviews

Now, let’s not go overboard with talk of AI. Even in the long term, the client facing nature of consulting means that firms will have live case interviews for as long as they are hiring anyone. And in the immediate term, case interviews are still absolutely the core of consulting selection.

Before landing an offer at McKinsey, Bain, BCG or any similar firm, you won’t just have one case interview, but will have to complete four to six case interviews, usually divided into two rounds, with each interview lasting approximately 50-60 minutes .

Being invited to first round usually means two or three case interviews. As noted above, you might also be asked to complete an online case or similar alongside your first round interviews.

If you ace first round, you will be invited to second round to face the same again, but more gruelling. Only then - after up to six case interviews in total, can you hope to receive an offer.

2.3. Typical case interview format

Before we dive in to the nuts and bolts of case cracking, we should give you a bit more detail on what exactly you’ll be up against on interview day.

Case interviews come in very similar formats across the various consultancies where they are used.

The standard case interview can be thought of as splitting into two standalone sub-interviews. Thus “case interviews” can be divided into the case study itself and a “fit interview” section, where culture fit questions are asked.

This can lead to a bit of confusion, as the actual case interview component might take up as little as half of your scheduled “case interview”. You need to make sure you are ready for both aspects.

To illustrate, here is the typical case interview timeline:

• First 15-30 minutes: Fit Interview - with questions assessing your motivation to be a consultant in that specific firm and your traits around leadership and teamwork. Learn more about the fit interview in our in-depth article here .
• Next 30-40 minutes: Case Interview - solving a case study
• Last 5 minutes: Fit Interview again - this time focussing on your questions for your interviewer.

Both the Case and Fit interviews play crucial roles in the finial hiring decision. There is no “average” taken between case and fit interviews: if your performance is not up to scratch in either of the two, you will not be able to move on to the next interview round or get an offer.

NB: No case without fit

Note that, even if you have only been told you are having a case interview or otherwise are just doing a case study, always be prepared to answer fit questions. At most firms, it is standard practice to include some fit questions in all case interviews, even if there are also separate explicit fit interviews, and interviewers will almost invariably include some of these questions around your case. This is perfectly natural - imagine how odd and artificial it would be to show up to an interview, simply do a case and leave again, without talking about anything else with the interviewer before or after.

2.4. Differences between first and second round interviews

Despite interviews in the first and second round following the same format, second/final round interviews will be significantly more intense. The seniority of the interviewer, time pressure (with up to three interviews back-to-back), and the sheer value of the job at stake will likely make a second round consulting case interview one of the most challenging moments of your professional life.

There are three key differences between the two rounds:

• Time Pressure : Final round case interviews test your ability to perform under pressure, with as many as three interviews in a row and often only very small breaks between them.
• Focus : Since second round interviewers tend to be more senior (usually partners with 12+ years experience) and will be more interested in your personality and ability to handle challenges independently. Some partners will drill down into your experiences and achievements to the extreme. They want to understand how you react to challenges and your ability to identify and learn from past mistakes.
• Psychological Pressure: While case interviews in the first round are usually more focused on you simply cracking the case, second round interviewers often employ a "bad cop" strategy to test the way you react to challenges and uncertainty.

2.5. Differences between firms

For the most part, a case interview is a case interview. However, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

As we’ll see, these differences aren’t hugely impactful in terms of how you prepare. That said, it's always good to know as much as possible about what you will be going up against.

2.5.1. Candidate led vs interviewer led case formats

Most consulting case interview questions test your ability to crack a broad problem, with a case prompt often going something like:

" How much would you pay to secure the rights to run a restaurant in the British Museum? "

You, as a candidate, are then expected to identify your path to solve the case (that is, provide a structure), leveraging your interviewer to collect the data and test your assumptions.

This is known as a “candidate-led” case interview and is used by Bain, BCG and other firms.

However, a McKinsey case interview - especially in the first round - is slightly different, with the interviewer controlling the pace and direction of the conversation much more than with other case interviews.

At McKinsey, your interviewer will ask you a set of pre-determined questions, regardless of your initial structure. For each question, you will have to understand the problem, come up with a mini structure, ask for additional data (if necessary) and come to the conclusion that answers the question.

McKinsey’s cases are thus referred to as “interviewer-led”. This more structured format of case also shows up in online cases by other firms - notably including BCG’s Casey chatbot (with the amusing result that practising McKinsey-style cases can be a great addition when prepping for BCG).

Essentially, these interviewer-led case studies are large cases made up of lots of mini-cases. You still use basically the same method as you would for standard (or candidate-led) cases - the main difference is simply that, instead of using that method to solve one big case, you are solving several mini-cases sequentially.

2.5.2. The McKinsey PEI

McKinsey brands its fit aspect of interviews as the Personal Experience Interview or PEI. Despite the different name, this is really much the same interview you will be going up against in Bain, BCG and any similar firms.

McKinsey does have a reputation for pushing candidates a little harder with fit or PEI questions, focusing on one story per interview and drilling down further into the specific details each time. We discuss this tendency more in our fit interview article. However, no top end firm is going to go easy on you and you should absolutely be ready for the same level of grilling at Bain, BCG and others. Thus any difference isn’t hugely salient in terms of prep.

2.6. How are things changing in 2023?

For the foreseeable future, you are going to have to go through multiple live case interviews to secure any decent consulting job. These might increasingly happen via Zoom rather than in person, but they should remain largely the same otherwise.

However, things are changing and the rise of AI in recent months seems pretty much guaranteed to accelerate existing trends.

Even before the explosive development of AI chatbots like ChatGPT we have seen in recent months, automation was already starting to change the recruitment process.

As we mentioned, case interviews are expensive and inconvenient for firms to run. Ideally, then, firms will try to reduce the number of interviews required for recruitment as far as possible. For many years, tests of various kinds served to cut down the applicant pool and thus the number of interviews. However, these tests had a limited capacity to assess candidates against the full consulting skillset in the way that case interviews do so well.

More recently, though, the development of online testing has allowed for more and more advanced assessments. Top consulting firms have been leveraging screening tests that better and better capture the same skillset as case interviews. Eventually this is converging on automated case studies. We see this very clearly with the addition of the Redrock case to McKinsey’s Solve assessment.

As these digital cases become closer to the real thing, the line between test and interview blurs. Online cases don’t just reduce the number of candidates to interview, but start directly replacing interviews.

Case in point here is BCG’s Casey chatbot . Previously, BCG had deployed less advanced online cases and similar tests to weed out some candidates before live case interviews began. Now, though, Casey actually replaces one first round case interview.

Casey, at time of writing, is still a relatively “dumb” chatbot, basically running through a pre-set script. The Whatsapp-like interface does a lot of work to make it feel like one is chatting to a “real person” - the chatbot itself, though, cannot provide feedback or nudges to candidates as would a human interviewer.

We fully expect that, as soon as BCG and other firms can train a truer AI, these online cases will become more widespread and start replacing more live interviews.

We discuss the likely impacts of advanced AI on consulting recruitment and the industry more broadly in our blog.

Here, though, the real message is that you should expect to run into digital cases as well as traditional case interviews.

Luckily, despite any changes in specific format, you will still need to master the same fundamental skills and prepare in much the same way.

We’ll cover a few ways to help prepare for chatbot cases in section four. Ultimately, though, firms are looking for the same problem solving ability and mindset as a real interviewer. Especially as chatbots get better at mimicking a real interviewer, candidates who are well prepared for case cracking in general should have no problem with AI administered cases.

2.6.1. Automated fit interviews

Analogous to online cases, in recent years there has been a trend towards automated, “one way” fit interviews, with these typically being administered for consultancies by specialist contractors like HireVue or SparkHire.

These are kind of like Zoom interviews, but if the interviewer didn’t show up. Instead you will be given fit questions to answer and must record your answer in your computer webcam. Your response will then go on to be assessed by an algorithm, scoring both what you say and how you say it.

Again, with advances in AI, it is easy to imagine these automated interviews going from fully scripted interactions, where all candidates are asked the same list of questions, to a more interactive experience. Thus, we might soon arrive at a point where you are being grilled on the details of your stories - McKinsey PEI style - but by a bot rather than a human.

We include some tips on this kind of “one way” fit interview in section six here.

3. What do I need to learn to solve cases?

If you’re new to case cracking. You might feel a bit hopeless when you see a difficult case question, not having any idea where to start.

In fact though, cracking cases is much like playing chess. The rules you need to know to get started are actually pretty simple. What will make you really proficient is time and practice.

In this section, we’ll run through a high level overview of everything you need to know, linking to more detailed resources at every step.

3.1. Business fundamentals

Obviously, you are going to need to be familiar with basic business concepts in order to understand the case studies you are given in the first instance.

If you are coming from a business undergrad, an MBA or are an experienced hire, you might well have this covered already.

However, many consultants will be entering from engineering or similar backgrounds and the major consulting firms are hiring more and more PhDs and non-MBA master's graduates from all subjects. These individuals will need to get up to speed on business fundamentals.

Luckily, you don’t need a degree-level understanding of business to crack interview cases, and a lot of the information you will pick up by osmosis as you read through articles like this and go through cases.

However, some things you will just need to sit down and learn. We cover everything you need to know in some detail in our Case Academy course. However, some examples here of things you need to learn are:

• Basic accounting (particularly how to understand all the elements of a balance sheet)
• Basic economics
• Basic marketing
• Basic strategy

Note, though, that learning the very basics of business is the beginning rather than the end of your journey.

Once you are able to “speak business” at a rudimentary level, you should try to “become fluent” and immerse yourself in reading/viewing/listening to as wide a variety of business material as possible, getting a feel for all kinds of companies and industries - and especially the kinds of problems that can come up in each context and how they are solved.

The material put out by the consulting firms themselves is a great place to start, but you should also follow the business news and find out about different companies and sectors as much as possible between now and interviews. Remember, if you’re going to be a consultant, this should be fun rather than a chore!

3.2. How to solve cases like a real consultant

This is the really important bit.

If you look around online for material on how to solve case studies, a lot of what you find will set out framework-based approaches. However, as we have mentioned, these frameworks tend to break down with more complex, unique cases - with these being exactly the kind of tough case studies you can expect to be given in your interviews.

To address this problem, the MyConsultingCoach team has developed a new, proprietary approach to case cracking that replicates how top management consultants approach actual engagements.

MyConsultingCoach’s Problem Driven Structure approach is a universal problem solving method that can be applied to any business problem , irrespective of its nature.

As opposed to just selecting a generic framework for each case, the Problem Driven Structure approach works by generating a bespoke structure for each individual question and is a simplified version of the roadmap McKinsey consultants use when working on engagements.

The canonical seven steps from McKinsey on real projects are simplified to four for case interview questions, as the analysis required for a six-month engagement is somewhat less than that needed for a 45-minute case study. However, the underlying flow is the same.

This video has more information on how frameworks can be unreliable and how we address this problem:

Otherwise, let's zoom in to see how our method actually works in more detail:

3.2.1. Identify the problem

Identifying the problem means properly understanding the prompt/question you are given, so you get to the actual point of the case.

This might sound simple, but cases are often very tricky, and many candidates irretrievably mess things up within the first few minutes of starting. Often, they won’t notice this has happened until they are getting to the end of their analysis. Then, they suddenly realise that they have misunderstood the case prompt - and have effectively been answering the wrong question all along!

With no time to go back and start again, there is nothing to do. Even if there were time, making such a silly mistake early on will make a terrible impression on their interviewer, who might well have written them off already. The interview is scuppered and all the candidate’s preparation has been for nothing.

This error is so galling as it is so readily avoidable.

Our method prevents this problem by placing huge emphasis on a full understanding of the case prompt. This lays the foundations for success as, once we have identified the fundamental, underlying problem our client is facing, we focus our whole analysis around finding solutions to this specific issue.

Now, some case interview prompts are easy to digest. For example, “Our client, a supermarket, has seen a decline in profits. How can we bring them up?”. However, many of the prompts given in interviews for top firms are much more difficult and might refer to unfamiliar business areas or industries. For example, “How much would you pay for a banking license in Ghana?” or “What would be your key areas of concern be when setting up an NGO?”

Don’t worry if you have no idea how you might go about tackling some of these prompts!

In our article on identifying the problem and in our full lesson on the subject in our MCC Academy course, we teach a systematic, four step approach to identifying the problem , as well as running through common errors to ensure you start off on the right foot every time!

This is summarised here:

Following this method lets you excel where your competitors mess up and get off to a great start in impressing your interviewer!

3.2.2. Build your problem driven structure

After you have properly understood the problem, the next step is to successfully crack a case is to draw up a bespoke structure that captures all the unique features of the case.

This is what will guide your analysis through the rest of the case study and is precisely the same method used by real consultants working on real engagements.

Of course, it might be easier here to simply roll out one an old-fashioned framework, and a lot of candidates will do so. This is likely to be faster at this stage and requires a lot less thought than our problem-driven structure approach.

However, whilst our problem driven structure approach requires more work from you, our method has the advantage of actually working in the kind of complex case studies where generic frameworks fail - that is exactly the kind of cases you can expect at an MBB interview .

Since we effectively start from first principles every time, we can tackle any case with the same overarching method. Simple or complex, every case is the same to you and you don’t have to gamble a job on whether a framework will actually work

In practice, structuring a problem with our method means drawing up either an issue tree or an hypothesis tree , depending on how you are trying to address the problem.

These trees break down the overall problem into a set of smaller problems that you can then solve individually. Representing this on a diagram also makes it easy for both you and your interviewer to keep track of your analysis.

To see how this is done, let’s look at the issue tree below breaking down the revenues of an airline:

These revenues can be segmented as the number of customers multiplied by the average ticket price. The number of customers can be further broken down into a number of flights multiplied by the number of seats, times average occupancy rate. The node corresponding to the average ticket price can then be segmented further.

It is worth noting that the same problem can be structured in multiple valid ways by choosing different means to segment the key issues.

That said, not all valid structures are equally useful in solving the underlying problem. A good structure fulfils several requirements - including MECE-ness , level consistency, materiality, simplicity, and actionability. It’s important to put in the time to master segmentation, so you can choose a scheme isn’t only valid, but actually useful in addressing the problem.

After taking the effort to identify the problem properly, an advantage of our method is that it will help ensure you stay focused on that same fundamental problem throughout. This might not sound like much, but many candidates end up getting lost in their own analysis, veering off on huge tangents and returning with an answer to a question they weren’t asked.

Another frequent issue - particularly with certain frameworks - is that candidates finish their analysis and, even if they have successfully stuck to the initial question, they have not actually reached a definite solution. Instead, they might simply have generated a laundry list of pros and cons, with no clear single recommendation for action.

Clients employ consultants for actionable answers, and this is what is expected in the case interview. The problem driven structure excels in ensuring that everything you do is clearly related back to the key question in a way that will generate a definitive answer. Thus, the problem driven structure builds in the hypothesis driven approach so characteristic of real consulting practice.

You can learn how to set out your own problem driven structures in our article here and in our full lesson in the MCC Academy course.

Join thousands of other candidates cracking cases like pros

3.2.3. lead the analysis.

A problem driven structure might ensure we reach a proper solution eventually, but how do we actually get there?

We call this step " leading the analysis ", and it is the process whereby you systematically navigate through your structure, identifying the key factors driving the issue you are addressing.

Generally, this will mean continuing to grow your tree diagram, further segmenting what you identify as the most salient end nodes and thus drilling down into the most crucial factors causing the client’s central problem.

Once you have gotten right down into the detail of what is actually causing the company’s issues, solutions can then be generated quite straightforwardly.

To see this process in action, we can return to our airline revenue example:

Let’s say we discover the average ticket price to be a key issue in the airline’s problems. Looking closer at the drivers of average ticket price, we find that the problem lies with economy class ticket prices. We can then further segment that price into the base fare and additional items such as food.

Having broken down the issue to such a fine-grained level, solutions occur quite naturally. In this case, we can suggest incentivising the crew to increase onboard sales, improving assortment in the plane, or offering discounts for online purchases.

Our article on leading the analysis is a great primer on the subject, with our video lesson in the MCC Academy providing the most comprehensive guide available.

3.2.4. Provide recommendations

So you have a solution - but you aren’t finished yet!

Now, you need to deliver your solution as a final recommendation.

This should be done as if you are briefing a busy CEO and thus should be a one minute, top-down, concise, structured, clear, and fact-based account of your findings.

The brevity of the final recommendation belies its importance. In real life consulting, the recommendation is what the client has potentially paid millions for - from their point of view, it is the only thing that matters.

In an interview, your performance in this final summing up of your case is going to significantly colour your interviewer’s parting impression of you - and thus your chances of getting hired!

So, how do we do it right?

Barbara Minto's Pyramid Principle elegantly sums up almost everything required for a perfect recommendation. The answer comes first , as this is what is most important. This is then supported by a few key arguments , which are in turn buttressed by supporting facts .

Across the whole recommendation, the goal isn’t to just summarise what you have done. Instead, you are aiming to synthesize your findings to extract the key "so what?" insight that is useful to the client going forward.

All this might seem like common sense, but it is actually the opposite of how we relay results in academia and other fields. There, we typically move from data, through arguments and eventually to conclusions. As such, making good recommendations is a skill that takes practice to master.

We can see the Pyramid Principle illustrated in the diagram below:

To supplement the basic Pyramid Principle scheme, we suggest candidates add a few brief remarks on potential risks and suggested next steps . This helps demonstrate the ability for critical self-reflection and lets your interviewer see you going the extra mile.

The combination of logical rigour and communication skills that is so definitive of consulting is particularly on display in the final recommendation.

Despite it only lasting 60 seconds, you will need to leverage a full set of key consulting skills to deliver a really excellent recommendation and leave your interviewer with a good final impression of your case solving abilities.

Our specific article on final recommendations and the specific video lesson on the same topic within our MCC Academy are great, comprehensive resources. Beyond those, our lesson on consulting thinking and our articles on MECE and the Pyramid Principle are also very useful.

3.3. Common case types and the building blocks to solve them

You should tackle each new case on its own merits. However, that’s not to say there aren’t recurring themes that come up fairly reliably in cases - there absolutely are. Business is business and case studies will often feature issues like profitability, competition etc.

Old fashioned framework approaches would have you simply select a defined framework for each kind of case and, in effect, just run the algorithm and wait for a solution to fall out.

We’ve already explained how frameworks can let you down. In this context, too many candidates will fall into the trap of selecting a framework for that case type that simply won’t work for their specific case.

The counterpoint in favour of frameworks, though, is that they are at least fast and prevent you having to start from the ground up with a common kind of case.

Ideally, you should have the best of both worlds - and this is why, in our articles on this site and in our MCC Academy course, we have developed a set of “building bocks” for common case themes.

As they name suggests, building blocks give you modular components for different kinds of case to help build out your own custom structures faster. These then allow you to leverage the symmetries between cases without inheriting the inflexibility of frameworks.

Let’s take a look at five different case types and get a brief idea of how our building block approach helps you with each. You can find more detail on each in the full length articles linked, as well as in the full-length video lessons in our MCC Academy course.

3.3.1. Estimation

Consultants need to push forward to provide definitive recommendations to clients in a timely manner despite typically not having access to full information on a problem. Estimation of important quantities is therefore at the heart of real life consulting work.

Estimation is thus just as fundamental to case cracking.

A case interview might centre on an estimation question, and this might be quite common for a first round interview. However, estimation is also very likely to be a crucial part of pretty well any other kind of case question you receive is likely to include estimation as a crucial component of your analysis.

The kinds of estimation you might be asked to make in a case interview can be very daunting:

• How many bank branches are there in Italy?
• How many cars are sold in Berlin in one year?
• How many people will buy the latest high-tech smartphone on the market?

You might have no idea where to begin with these examples. However, tempting as it might be, your answer cannot ever be a simple guess .

A decent estimation does have a guessed element - though this should really be an educated guess based on some pre-existing knowledge. However, this guessed element is always then combined with a rigorous quantitative method to arrive at a reasonable estimation.

In context of a case interview, it’s important to realise that your interviewer doesn’t really care about the right answer (they don’t need to ask you to find out, after all). What’s important is showing the rational process by which you get to your answer.

A guess that was somehow exactly correct is no good compared to a “wrong” answer that was reached by a very sensible, intelligent process of estimation. In cases, this method will often be a matter of segmentation.

So, where would we start in working out how many cars are sold in Berlin, for example?

The key to estimation case questions is the ability to logically break down the problem into more manageable pieces. In consulting case studies, this will generally mean segmenting a wider population to find a particular target group. For example, starting from the total population of Berlin and narrowing down to the cohort of individuals who will buy a car that year.

There are usually many ways to segment the same starting population, and several different segmentation schemes might be equally valid. However, it is crucial to choose the specific method best suited to the goal in answering the question and allowing you to best leverage the data you have available.

Segmentation must be allied with assumptions in order to arrive at an estimation. These assumptions are the “guessed” element of estimations we mentioned above. Assumptions cannot just be plucked from thin air, but must always be reasonable .

The example below showcases both the segmentation and assumptions made in an estimation of the size of the wedding planning market in London:

Our articles on estimation and the MECE concept are great starting points in getting to grips with consulting estimation. However, the best place to learn how to make estimations is with the dedicated building block video lesson in our MCC Academy course.

Those of you from physics or engineering backgrounds will probably see a lot in common with Fermi questions . We have plenty of estimation cases for you to work through in our free case library. However, Fermi questions are a great way of getting a little extra practice and you can find a lifetime’s supply online.

3.3.2. Profitability

The fundamental goal of any normal business is to maximise profits - nobody is getting up and going to work to lose money. Even Silicon Valley tech start-ups are supposed to be profitable some day!

Profitability problems are thus bread and butter issues for management consultants.

Clients often tell consultants broadly the same story. The business was doing in well in recent years, with strong profits. However, some recent turn of events has upset the status quo and led to concerns around profit levels. Consultants are brought in as businesses are often sufficiently complex that it can be difficult to figure out precisely where and why the company is losing money - let alone how to then reverse the situation and restore healthy profits.

Despite steady growth in customer flow, the Walfort supermarket chain has seen falling profits in the past year. What is the reason for this decline?

Understanding profitability ultimately means understanding the various components that determine a company’s profit. You will need to learn to decompose profit first into revenues and costs (profit being the synthesis of these two factors). Crucially, you then need to segment further, distinguishing different specific revenue streams and separating various fixed and variable costs.

To take an example, just examining the revenue side of profit, the incoming revenues for an insurance firm might be broken down as follows:

Improving profitability will inherently mean increasing revenues and/or decreasing costs. To solve profitability problems, we thus have to understand the ways we can minimise different costs, as well as ways to drive sales and/or optimise pricing to increase revenue. Importantly, you must be able to judge which of these options is best suited to address specific scenarios.

The key to tackling the complex kind of profitability questions given by MBB-level consultancies lies in this proper segmentation.

By contrast, old-fashioned case interview frameworks will simply have you look at aggregate cost and revenue data before recommending generic cost-cutting or revenue-driving measures. However, this will often lead to negative outcomes in more involved cases, making matters worse for the client.

For example, it might well be that a company actually makes a loss when it serves a certain cohort of customers. An airline, for instance, might lose money on economy class customers but make a healthy profit on each business class customer. Attempts to boost revenue by increasing sales across the board might actually reduce profit further by increasing the number of economy class customers. What is required is targeted measures to increase focus on business class and/or mitigate economy class losses.

You can start learning to segment these kinds of cases properly in our article on profitability , whilst the best way to really master profitability questions is our full lesson on the subject in the Building Blocks section of our MCC Academy course.

3.3.3. Pricing

For a company to be profitable at all, it is a pre-requisite that it charges the right price for whatever it sells. However, establishing what price to charge for any one product - or indeed a whole suite of related products - can be a highly complex business.

Consultants are often engaged to negotiate the many variables, with all their complex interdependencies, at play in pricing. Correspondingly, then, pricing is a common theme in case interviews.

• A company launches a new smartphone with a significantly improved camera. How much should they charge?
• A doughnut chain wants to start selling coffee in their shops. How much should they charge per cup?

Clearly, lot of different factors can influence the answers to these questions, and it can be difficult to know where to start. To get a handle on all this complexity, you will need to take a methodical, structured approach.

To really understand pricing, you must begin from fundamentals like the customer’s willingness to pay, the value captured by the company, and the value created for the customer. These basics are shown in the diagram below:

This might seem simple enough, but the exact level at which prices are ultimately set is determined by a whole host of factors, including product availability, market trends, and the need to maintain a competitive position within the market. In particular, if we are changing the price of an existing product, we must consider how the price elasticity of demand might cause sales to fluctuate.

Our four-step method for pricing starts from establishing the customer’s next best alternative, calculating the value added by our own product, and working from there. A summary of this method is given, along with an overview of pricing in general, in our article on the subject . However, the most complete resource is our pricing lesson in the MCC Academy .

3.3.4. Valuation

Valuation is fundamental to any kind of investment. Before allocating capital towards a particular opportunity, an investor must understand precisely what value it holds and how this compares to the other available options.

In short, valuation tells us how much we should be willing to pay to acquire a company or an asset.

There are many ways to value an asset - indeed the finer points are still subject to research in both the academic and private sectors.

Standard ways to assign value include asset-based valuations (notably the Net Asset Value or NAV) and the various multiples so widely used by market traders.

However, in consulting case interviews, you will only usually need to be familiar with Net Present Value (NPV) . This means you need to learn and master the NPV equation:

CF = Cash Flow r = Discount Rate

Whilst this is a pretty simple equation on the face of it, in order to make proper use of it, you will also need to develop a feel for interest/discount rates appropriate to different cases. This will be essential, as you will often have to estimate rational values for these rates for different investments before plugging those values into the NPV equation. Our Case Academy course has more detail here.

Note, though, that NPV is only really half the story.

NPV provides a kind of “absolute” value for an asset. However, the fact is that the worth of any asset will be different for different buyers , depending largely upon what the buyer already owns. In just the same way a spare clutch for a 1975 Ford will be a lot less valuable to a cyclist than to someone restoring the relevant classic car, so a courier business will be more valuable to an online retailer than to an airline.

As such, what we call the Total Enterprise Value (TEV) of an asset is calculated as a function of that asset’s NPV and of the potential cost and revenue synergies resulting from an acquisition. This is shown in the useful structure below:

You can learn more about all aspects of valuation in our article here , as well as in our dedicated video lesson in MCC Academy . These include guides to the kind of interest rates typically required to finance different kinds of investment.

3.3.5. Competitive Interactions

Most of what we’ve discussed so far in terms of case themes and our building block approach to them will all depend upon the prevailing competitive landscape our client exists within. Product prices, profit levels and ultimately valuations can all change over time in response to competition.

What is more, the zero sum dynamics of competitive interactions mean that these things can change quickly .

Companies enjoying near monopolies for years or even decades can quickly see their values go to zero, or near enough, in the face of some innovation by a competitor coming onto the market.

Nokia and Kodak thoroughly dominated the mobile phone and photography markets respectively - until new companies with new products pulled the rug out from under them and led to precipitous collapses.

New market entrants or old competitors with new ideas can throw a company’s whole business model up in the air overnight . Complex decisions about profound changes need to be made yesterday. Firms trying to save themselves will often slash prices in attempts to maintain sales - though this can actually make things worse and result in a corporate death-spiral. Consultants are then frequently called in to help companies survive - with this type of engagement carrying over to inform case interview questions.

You are running an airline and a low-cost competitor, like Ryanair, decides to start operating on your routes. You are rapidly losing customers to their lower fares. How do you respond?

Your eventual solutions to competitive interaction problems will likely need to be novel and unique to the situation. However, the process by which we understand competitive interactions and move towards those solutions is usually very methodical, moving through the limited dimensions in which a company can take action.

The following structure neatly encodes the general options open to responding to new sources of competition:

Of course, we would never suggest that you blanket-apply any strict, inflexible methodology to a whole swathe of case questions – this is precisely the approach that causes so much trouble for candidates using old-fashioned frameworks.

This structure is only a starting point - a shortcut to a bespoke framework specific to the case question in hand. You might well have to alter the details of the structure shown and you will almost certainly have to expand it as you lead the analysis . How you build out your structure and the solutions you provide are necessarily going to depend upon the specific details of the case question.

Thus, in order to deal with competitive interactions, you will need to put in the time to understand how the different strategies available function - as well as how competitors might then react to implementing such strategies. With enough practice, though, soon you won’t be fazed by even the most complex cases of competition between firms.

You can learn more in our article here and in our dedicated video lesson on competitive interaction in the MCC Academy case interview course.

3.4. Mental mathematics

Almost every interview case study will feature some mental mathematics and this is an area where many many candidates let themselves down.

As such, it makes sense to out in the time and make sure you are fully proficient.

Nothing beyond high school level is required, but you probably don’t do much mental arithmetic day to day and will likely need to practice quite a lot to get good enough to reliably perform at pace, under pressure.

We give a high-level overview of what you need to know in our consulting math article , but devote a whole section of our MCC Academy course to a deep dive on consulting math, with plenty of practice material to get you up to scratch.

4. How do I practice for case interviews?

As we said above - case interviews are much like chess. The rules are relatively quick to learn, but you need to practice a lot to get good.

If you’re working through our MCC Academy course, we recommend getting through the core Problem Driven Structure section. After that, you should be practising alongside working through the remainder of the course and beyond. However you do things, you need to get up to speed with the fundamentals before practice is going to do much more than confuse you.

Of course, if you’re enrolled in one of our mentoring programmes , your mentor will let you know precisely when and how you should be scheduling practice, as well as tracking your progress throughout.

4.1. Solo Practice

For solitary preparation, one of the best uses of your time is to work on your mental mathematics . This skill is neglected by many applicants - much to their immediate regret in the case interview. Find our mental math tool here or in our course, and practice at least ten minutes per day, from day one until the day before the interview.

Once you've covered our Building Blocks section, you should then start working through the cases in My Consulting Coach's case bank alongside your work on the course. This is a large library of case interview questions and answers in different formats and difficulties.

To build your confidence, start out on easier case questions, work through with the solutions, and don't worry about time. As you get better, you can move on to more difficult cases and try to get through them more quickly. You should practice around eight case studies on your own to build your confidence.

4.2. Peer practice

One you have worked through eight cases solo, you should be ready to simulate the interview more closely and start working with another person.

Here, many candidates turn to peer practice - that is, doing mock case interviews with friends, classmates or others also applying to consulting.

If you’re in university, and especially in business school, there will very likely be a consulting club for you to join and do lots of case practice with. If you don’t have anyone to practice, though, or if you just want to get a bit more volume in with others, our free meeting board lets you find fellow applicants from around the world with whom to practice.

4.3. Professional practice

You can do a lot practising by yourself and with peers. However, nothing will bring up your skills so quickly and profoundly as working with a real consultant.

Perhaps think about it like boxing. You can practice drills and work on punch bags all you want, but at some point you need to get into the ring and do some actual sparring if you ever want to be ready to fight.

Of course, it isn’t possible to secure the time of experienced top-tier consultants for free. However, when considering whether you should invest to boost your chances of success, it is worth considering the difference in your salary over even a just few years between getting into a top-tier firm versus a second-tier one. In the light of thousands in increased annual earnings (easily accumulating into millions over multiple years), it becomes clear that getting expert interview help really is one of the best investments you can make in your own future.

Should you decide to make this step, MyConsultingCoach can help, offering the highest quality case interview coaching service available . Each MCC case coach is selected as an MBB consultant with two or more years of experience and strong coaching expertise.

Case interview coaching is hugely beneficial in itself. However, for those who want to genuinely maximise their chances of securing a job offer - and especially for time-poor, busy professionals or hard-pressed students who want to take the guesswork and wasted time out of their case interview prep - we also offer a much more comprehensive service .

With one of our bespoke mentoring programmes , you are paired with a 5+ year experienced, ex-MBB mentor of your choosing, who will then oversee your whole case interview preparation from start to finish - giving you your best possible chance of landing a job!

4.4. Practice for online cases

Standard preparation for interview case studies will carry directly over to online cases.

However, if you want to do some more specific prep, you can work through cases solo to a timer and using a calculator and/or Excel (online cases generally allow calculators and second computers to help you, whilst these are banned in live case interviews).

Older PST-style questions also make great prep, but a particularly good simulation is the self-assessment tests included in our Case Academy course . These multiple choice business questions conducted with a strict time limit are great preparation for the current crop of online cases.

5. Fit interviews

As we’ve noted, even something billed as a case interview is very likely to contain a fit interview as a subset.

We have an article on fit interviews and also include a full set of lessons on how to answer fit questions properly as a subset of our comprehensive Case Academy course .

Here though, the important thing to convey is that you take preparing for fit questions every bit as seriously as you do case prep.

Since they sound the same as you might encounter when interviewing for other industries, the temptation is to regard these as “just normal interview questions”.

However, consulting firms take your answers to these questions a good deal more seriously than elsewhere.

This isn’t just for fluffy “corporate culture” reasons. The long hours and close teamwork, as well as the client-facing nature of management consulting, mean that your personality and ability to get on with others is going to be a big part of making you a tolerable and effective co-worker.

If you know you’ll have to spend 14+ hour working days with someone you hire and that your annual bonus depends on them not alienating clients, you better believe you’ll pay attention to their character in interview.

There are also hard-nosed financial reasons for the likes of McKinsey, Bain and BCG to drill down so hard on your answers.

In particular, top consultancies have huge issues with staff retention. The average management consultant only stays with these firms for around two years before they have moved on to a new industry.

In some cases, consultants bail out because they can’t keep up with the arduous consulting lifestyle of long hours and endless travel. In many instances, though, departing consultants are lured away by exit opportunities - such as the well trodden paths towards internal strategy roles, private equity or becoming a start-up founder.

Indeed, many individuals will intentionally use a two year stint in consulting as something like an MBA they are getting paid for - giving them accelerated exposure to the business world and letting them pivot into something new.

Consulting firms want to get a decent return on investment for training new recruits. Thus, they want hires who not only intend to stick with consulting longer-term, but also have a temperament that makes this feasible and an overall career trajectory where it just makes sense for them to stay put.

This should hammer home the point that, if you want to get an offer, you need to be fully prepared to answer fit questions - and to do so excellently - any time you have a case interview.

6. Interview day - what to expect, with tips

Of course, all this theory is well and good, but a lot of readers might be concerned about what exactly to expect in real life . It’s perfectly reasonable to want to get as clear a picture as possible here - we all want to know what we are going up against when we face a new challenge!

Indeed, it is important to think about your interview in more holistic terms, rather than just focusing on small aspects of analysis. Getting everything exactly correct is less important than the overall approach you take to reasoning and how you communicate - and candidates often lose sight of this fact.

In this section, then, we’ll run through the case interview experience from start to finish, directing you to resources with more details where appropriate. As a supplement to this, the following video from Bain is excellent. It portrays an abridged version of a case interview, but is very useful as a guide to what to expect - not just from Bain, but from McKinsey, BCG and any other high-level consulting firm.

6.1. Getting started

Though you might be shown through to the office by a staff member, usually your interviewer will come and collect you from a waiting area. Either way, when you first encounter them, you should greet your interviewer with a warm smile and a handshake (unless they do not offer their hand). Be confident without verging into arrogance. You will be asked to take a seat in the interviewer’s office, where the interview can then begin.

6.1.1. First impressions

In reality, your assessment begins before you even sit down at your interviewer’s desk. Whether at a conscious level or not, the impression you make within the first few seconds of meeting your interviewer is likely to significantly inform the final hiring decision (again, whether consciously or not).

Your presentation and how you hold yourself and behave are all important. If this seems strange, consider that, if hired, you will be personally responsible for many clients’ impressions of the firm. These things are part of the job! Much of material on the fit interview is useful here, whilst we also cover first impressions and presentation generally in our article on what to wear to interview .

As we have noted above, your interview might start with a fit segment - that is, with the interviewer asking questions about your experiences, your soft skills, and motivation to want to join consulting generally and that firm in particular. In short, the kinds of things a case study can’t tell them about you. We have a fit interview article and course to get you up to speed here.

6.1.2. Down to business

Following an initial conversation, your interviewer will introduce your case study , providing a prompt for the question you have to answer. You will have a pen and paper in front of you and should (neatly) note down the salient pieces of information (keep this up throughout the interview).

It is crucial here that you don’t delve into analysis or calculations straight away . Case prompts can be tricky and easy to misunderstand, especially when you are under pressure. Rather, ask any questions you need to fully understand the case question and then validate that understanding with the interviewer before you kick off any analysis. Better to eliminate mistakes now than experience that sinking feeling of realising you have gotten the whole thing wrong halfway through your case!

This process is covered in our article on identifying the problem and in greater detail in our Case Academy lesson on that subject.

6.1.3. Analysis

Once you understand the problem, you should take a few seconds to set your thoughts in order and draw up an initial structure for how you want to proceed. You might benefit from utilising one or more of our building blocks here to make a strong start. Present this to your interviewer and get their approval before you get into the nuts and bolts of analysis.

We cover the mechanics of how to structure your problem and lead the analysis in our articles here and here and more thoroughly in the MCC Case Academy . What it is important to convey here, though, is that your case interview is supposed to be a conversation rather than a written exam . Your interviewer takes a role closer to a co-worker than an invigilator and you should be conversing with them throughout.

Indeed, how you communicate with your interviewer and explain your rationale is a crucial element of how you will be assessed. Case questions in general, are not posed to see if you can produce the correct answer, but rather to see how you think . Your interviewer wants to see you approach the case in a structured, rational fashion. The only way they are going to know your thought processes, though, is if you tell them!

To demonstrate this point, here is another excellent video from Bain, where candidates are compared.

Note that multiple different answers to each question are considered acceptable and that Bain is primarily concerned with the thought processes of the candidate’s exhibit .

Another reason why communication is absolutely essential to case interview success is the simple reason that you will not have all the facts you need to complete your analysis at the outset. Rather, you will usually have to ask the interviewer for additional data throughout the case to allow you to proceed .

NB: Don't be let down by your math!

Your ability to quickly and accurately interpret these charts and other figures under pressure is one of the skills that is being assessed. You will also need to make any calculations with the same speed and accuracy (without a calculator!). As such, be sure that you are up to speed on your consulting math .

6.1.4. Recommendation

Finally, you will be asked to present a recommendation. This should be delivered in a brief, top-down "elevator pitch" format , as if you are speaking to a time-pressured CEO. Again here, how you communicate will be just as important as the details of what you say, and you should aim to speak clearly and with confidence.

For more detail on how to give the perfect recommendation, take a look at our articles on the Pyramid Principle and providing recommendations , as well the relevant lesson within MCC Academy .

6.1.5. Wrapping up

After your case is complete, there might be a few more fit questions - including a chance for you to ask some questions of the interviewer . This is your opportunity to make a good parting impression.

We deal with the details in our fit interview resources. However, it is always worth bearing in mind just how many candidates your interviewers are going to see giving similar answers to the same questions in the same office. A pretty obvious pre-requisite to being considered for a job is that your interviewer remembers you in the first place. Whilst you shouldn't do something stupid just to be noticed, asking interesting parting questions is a good way to be remembered.

Now, with the interview wrapped up, it’s time to shake hands, thank the interviewer for their time and leave the room .

You might have other interviews or tests that day or you might be heading home. Either way, if know that you did all you could to prepare, you can leave content in the knowledge that you have the best possible chance of receiving an email with a job offer. This is our mission at MCC - to provide all the resources you need to realise your full potential and land your dream consulting job!

6.2. Remote and one-way interview tips

Zoom case interviews and “one-way” automated fit interviews are becoming more common as selection processes are increasingly remote, with these new formats being accompanied by their own unique challenges.

Obviously you won’t have to worry about lobbies and shaking hands for a video interview. However, a lot remains the same. You still need to do the same prep in terms of getting good at case cracking and expressing your fit answers. The specific considerations around remote interviews are, in effect, around making sure you come across as effectively as you would in person.

6.2.1. Connection

It sounds trivial, but a successful video interview of any kind presupposes a functioning computer with a stable and sufficient internet connection.

Absolutely don’t forget to have your laptop plugged in, as your battery will definitely let you down mid-interview. Similarly, make sure any housemates or family know not to use the microwave, vacuum cleaner or anything else that makes wifi cut out (or makes a lot of noise, obviously)

If you have to connect on a platform you don’t use much (for example, if it’s on Teams and you’re used to Zoom), make sure you have the up to date version of the app in advance, rather than having to wait for an obligatory download and end up late to join. Whilst you’re at it, make sure you’re familiar with the controls etc. At the risk of being made fun of, don’t be afraid to have a practice call with a friend.

6.2.2. Dress

You might get guidance on a slightly more relaxed dress code for a Zoom interview. However, if in doubt, dress as you would for the real thing (see our article here ).

Either way, always remember that presentation is part of what you are being assessed on - the firm needs to know you can be presentable for clients. Taking this stuff seriously also shows respect for your interviewer and their time in interviewing you.

6.2.3. Lighting

An aspect of presentation that you have to devote some thought to for a Zoom interview is your lighting.

Hopefully, you long ago nailed a lighting set-up during the Covid lockdowns. However, make sure to check your lighting in advance with your webcam - bearing in mind what time if day your interview actually is. If your interview is late afternoon, don’t just check in the morning. Make sure you aren’t going to be blinded from light coming in a window behind your screen, or that you end up with the weird shadow stripes from blinds all over your face.

Natural light is always best, but if there won’t be much of that during your interview, you’ll likely want to experiment with moving some lamps around.

6.2.4. Clarity

The actual stories you tell in an automated “one-way” fit interview will be the same as for a live equivalent. If anything, things should be easier, as you can rattle off a practised monologue without an interviewer interrupting you to ask for clarifications.

You can probably also assume that the algorithm assessing your performance is sufficiently capable that it will be observing you at much the same level as a human interviewer. However, it is probably still worth speaking as clearly as possible with these kinds of interviews and paying extra attention to your lighting to ensure that your face is clearly visible.

No doubt the AIs scoring these interviews are improving all the time, but you still want to make their job as easy as possible. Just think about the same things as you would with a live Zoom interview, but more so.

7. How we can help

There are lots of great free resources on this site to get you started with preparation, from all our articles on case solving and consulting skills to our free case library and peer practice meeting board .

To step your preparation up a notch, though, our Case Academy course will give you everything you need to know to solve the most complex of cases - whether those are in live interviews, with chatbots, written tests or any other format.

Whatever kind of case you end up facing, nothing will bring up your skillset faster than the kind of acute, actionable feedback you can get from a mock case interview a real, MBB consultant. Whilst it's possible to get by without this kind of coaching, it does tend to be the biggest single difference maker for successful candidates.

You can find out more on our coaching page:

The HBS Interview: What to Expect + Sample Questions

Oct 6, 2023

How the HBS interview works

The post-interview reflection, who is harvard looking for, how can you prepare for your hbs interview, what to do if you get a question you haven’t prepared an answer for, effectively tell your story during your hbs interview.

UPDATE : This article was originally posted on February 6, 2019. It has been updated with new information and tips below. 

When many people think “business school,” the first MBA that pops into their mind is Harvard Business School. Established in 1908, HBS has been at the forefront of business education for more than a century. 

However, receiving more than 8,000 applications per year, Harvard Business School is one of the most difficult MBA programs to enter. 

That’s why we’ve prepared this guide to help you use your Harvard admissions interview to stand out. We’ve rounded up not only our best tips but have also included sample HBS interview questions to ensure you give your Harvard application your best shot.

The Harvard interview is one of the most sought-after – and most difficult – interviews to land in the business school world. 

Thus, if you have passed to the interview phase of the Harvard application process, congratulations! This is already an exceptional achievement. 

The HBS interviews are fast-paced, often including as many as 20-30 questions in the space of 30 minutes! Furthermore, though HBS interviewers do sometimes ask a few standard MBA interview questions, most of the questions you will receive are tailored to your profile and/or are follow-up questions to answers you give during the interview . We believe that HBS adopts this type of interview style to test how well you would fit into the case study classroom environment. 

Despite its fast pace, our clients who have interviewed with Harvard say that the interviewer was very friendly and demonstrated a genuine interest in their answers. 

For some clients, questions were far more personal in nature, covering topics like their childhood and family upbringing. Other clients reported their interview was strictly professional, so make sure you’re ready for anything when you interview with HBS. 

Who will interview you?

Members of the HBS admissions committee. You will be interviewed by one or two people. 

Will the interviewer have read my application?

Yes. Since a member of the adcom will interview you, they will have read your entire application before the interview. 

How long will the HBS interview last?

30 minutes. The HBS interview is exactly timed and will not last longer than half an hour.

Where will my interview take place?

After two years of conducting interviews exclusively online, HBS is now offering the option to complete interviews either on Zoom or on campus. After being invited to interview, you will receive a link through which you can schedule a time for your interview. 

If you choose to complete your interview virtually, it will not negatively impact your application in any way. However, if you haven’t had the chance to visit campus yet. 

Unlike other most business schools, all candidates that are selected to interview at HBS must answer this open-ended question and submit their answers within 24 hours of their interviews. 

As part of the application process, you will be required to complete a Post-Interview Reflection. Here are a few details straight from Harvard Business School:

• The Post-Interview Reflection is not intended to be another formal essay. Think of it instead as a reflection after a meeting.
• We will be much more generous in our reaction to typos and grammatical errors than we will be with pre-packaged responses. Reflections that give any indication that they were produced before you had the interview will raise a flag for us.
• We do not expect you to solicit or receive any outside assistance with this exercise.
• Your Post-Interview Reflection is due within 24 hours of the conclusion of your interview. Let the interview soak in a little bit…no need to start writing your reflection right at the conclusion of your interview.
• There is a word guidance of 300-450 words for the Post-Interview Reflection.

Though there is no “model” for how to respond to this question, we have gathered several tips to help you ace this part of the HBS interview process here .

Every year, Harvard Business School admits the largest single MBA class in the world, with around 1000 students starting each year. In general, Harvard tends to admit applicants with 4.9 years of work experience and outstanding test scores. The median GMAT for the Class of 2025 was 740 and the median GRE was 163Q, 163V.   

Harvard also places a strong emphasis on diversity, with the Class of 2025 containing 45% women and 39% international students. 

According to Harvard’s Admissions team:

In addition, some of the key characteristics HBS looks for in applicants are:

Habit of Leadership

Leadership may be expressed in many forms, from college extracurricular activities to academic or business achievements, from personal accomplishments to community commitments. We appreciate leadership on any scale, from organizing a classroom to directing a combat squad, from running an independent business to spearheading initiatives at work. In essence, we are looking for evidence of your potential.

Analytical Aptitude and Appetite

Harvard Business School is a demanding, fast-paced, and highly-verbal environment. We look for individuals who enjoy lively discussion and debate. Our case and field-based methods of learning depend upon the active participation of prepared students who can assess, analyze, and act upon complex information within often-ambiguous contexts. The MBA Admissions Board will review your prior academic performance, the results of the GMAT or GRE, and, if applicable, TOEFL iBT and/or IELTS, and the nature of your work experience. There is no particular previous course of study required to apply; you must, however, demonstrate the ability to master analytical and quantitative concepts.

Engaged Community Citizenship

So much of our MBA experience – including the case method, section life, and student-organized events – requires the active collaboration of the entire HBS community. That’s why we look for students who exhibit the highest ethical standards and respect for others, and can make positive contributions to the MBA Program. The right candidates must be eager to share their experiences, support their colleagues, and teach as well as learn from their peers.

We want applicants who have these traits, as well as bring a variety of skills, accomplishments and aspirations. In each class, we create a dynamic environment that mirrors the breadth and depth of our world economy. Our promise to our faculty and to every student here is to create a class of 900 students who come from as many different backgrounds and perspectives as possible.

The questions you get at HBS will be very tailored to your profile and will adapt as the conversation develops. 

For example, if you say: “I’d really love to do my summer internship in a technology company,” your interviewer might follow with: “Which 3 companies would you apply to?” As such, make sure you have combed through your application and have considered all types of questions and follow-up questions your interviewer might be interested in asking you. 

Though most questions are unpredictable, HBS does also draw upon some of the more common MBA interview questions, such as those asking why you are interested in attending an MBA in light of your career goals, why you’re interested in HBS, and what you bring to the Harvard community. As such, we have prepared some model questions below that previous candidates have received in their past HBS interviews.

Sample HBS Interview Questions

The questions below are drawn from our clients’ interview reports, as well as from sites like clearadmit.com . These are not all the potential questions you could possibly receive during your HBS interview. These are not even necessarily questions that you will receive on your HBS interview. However, these questions will help you understand what sort of questions to expect as you critically review your HBS application and consider what the adcom might dive into during your interview. 

The best way to prepare for HBS is to practice .

Despite your most diligent preparation, you will almost always receive a question you had not prepared. 

First, stay calm and take a deep breath. You have already made it this far in the process, and one question will not trip you up!

Second, make sure you directly answer the question the interviewer asked you. For example, if the interviewer asks you about a time you had to deal with a difficult manager, make sure to tell a story about a difficult manager and how you handled the situation. 

If you’re having trouble thinking of an answer or an example to support your answer , however, take a drink of water to give yourself a few more minutes to think. If you really can’t think of an example from your personal or professional experience, you can use a hypothetical answer about how you would act in a certain situation. 

Finally, assume that the interviewer is testing how you think on your feet and respond to questions you didn’t prepare in advance . Though your answer might not be as polished as if you’d had weeks to rehearse it, smile and confidently give your answer to show you can respond to any question they throw at you. 

One of the most common mistakes we see in MBA interviews is that candidates fail to tell compelling, well-constructed stories about their profiles while also nailing the basics. 

Striking this balance between sharing STAR-format examples that show off your background while also presenting strong answers to questions like “Why do you want an MBA?” is a challenging task that requires significant thought and preparation. 

Because of this, it’s no surprise that, on average, 50% of interviewed applicants walk away without an offer . 

This is why our interview preparation process here at Ellin Lolis Consulting is known as the best in the industry. We offer customized 1:1 support that ensures you’re able to turn your application’s strengths into compelling answers that show fit and sell your profile in any type of interview.   

That’s the approach we took with Marina, who was admitted to HBS. In her words, 

“My favorite part of working with Ellin Lolis was how well she knew my application and resume and customized the questions so they were realistic and compatible with my story.

Working with Ellin was essential to get into HBS. She prepared me for the interview in a complete manner: question customized for my history, amazing feedback (with orientation and examples on how to improve) as well as a complete post-mock session email with all the practiced questions, answers and feedback

While the consulting case study interview may seem daunting at first, most cases follow a typical song-and-dance. Once you get a hang of it, prepping feels much more manageable. The first part of this guide will give a broad overview of the case interview. The second part will break out the typical structure of an interviewee-led case. The last part will dive into each component, with tips and suggestions for preparing. Note that some firms may have their own specific case interview style. Be sure to familiarize yourself with your target firms’ interview processes before the time comes to recruit.

Case interviews involve tackling a business issue or problem faced by a company (the client). These interviews allow consulting firms to gauge candidates’ ability to perform the job. Specifically, firms are testing whether candidates can:

• Think in a structured and creative way
• Analyze and interpret new information
• Communicate persuasively and succinctly

Most firms conduct interviewee-led cases, as outlined in the guide below. In these cases, the candidate is expected to drive the case forward by asking the interviewer for data or information relevant to forming the recommendation. A few firms, most notably McKinsey, are interviewer-led, meaning that the interviewer will be the one guiding the discussion.

Below are a few common types of cases that you can expect to receive. Some cases can be several types all in one (lucky you!):

• Profitability - Determine cause for profit decline and / or ideas for increasing profit; you will rarely get a standalone profitability case – It will usually be rolled up in another case type
• Growth - consider strategies for company growth; could be through sales or market share
• Market Entry / New Business - Assess attractiveness of entering new geography / business / sector and method for entering
• Due Diligence / M&A - Assess attractiveness of purchasing / acquiring a company or business; client can be another company or a financial sponsor
• Competitive Response - Address a competitor’s recent action (e.g., new acquisition, change in pricing strategy)
• Non-Traditional - Similar to the other cases but the client (non-profit, NGO, education-focused entity) has different objectives than a typical corporate company

Case Interview Components

• Prompt: Interviewer reads aloud the case while the interviewee takes notes
• Recap: Interviewee provides a high-level summary of the case and confirms accuracy of information written
• Clarifying Questions: Interviewee asks 2-3 high-level questions
• Structuring (<2 minutes): Interviewee takes a few minutes create a roadmap for approaching the case
• Framework Presentation (2-3 minutes): Interviewee reviews the structure with the interviewer, who may have follow-up questions. Interviewee then moves the case forward by asking for additional information
• Brainstorming: Interviewee is expected to list out several solutions or ideas (e.g., cost drivers for an industry, ways to increase sales)
• Exhibits: Interviewee will be given data in forms such as graphs or charts and expected to provide high-level insights
• Math: Interviewee will be asked to perform a calculation with the new information or using data from the exhibits. Oftentimes, interviewee is not given enough information and must ask for the relevant data
• Synthesis and Recommendation (2-3 minutes) : Interviewee provides the answer first, then supporting facts from the case, and finally risks and next steps

Setup (2-3 minutes)

Prompt : The interviewer may be giving you A LOT of information - don’t write down everything verbatim. Jot down facts and figures, the client name, and the objective(s). If you miss something or don’t remember what a number means, you can ask after your recap.

• Prep: Have a friend read you several different case interview prompts and practice taking down notes. Create your own shorthand and learn how to recognize extraneous pieces of information

Recap : I always reference the client by name and start my recap with the objective(s) first, since this is the most important part of the case. The recap should be summarized, not verbatim, and you should be checking that the figures you wrote down are correct.

• Prep: Practice summarizing your notes out loud instead of repeating the case verbatim. Time yourself to make sure it’s <1 minute.

Clarifying Questions : Very detailed questions should be saved for the case. Clarifying questions are meant to help you with your structure or alleviate any confusion. Keep these at 2-3 questions. I usually ask questions pertaining to:

• Language/terminology - The interviewer won’t expect you to know the nuances of every industry or practice area. It is better you start off the case on the right footing by asking for clarifying definitions
• Goals/objectives - I always ask if there are other goals the company has in mind and, if relevant, specific financial targets or timeframe. Sometimes, the objective given is vague, so I will ask the interviewer to be more specific.
• Business model or geography - Very helpful for cases in niche industries; understanding geography can also prompt you to think about factors like labor cost or global competition
• Scope - To save you time from considering every possibility, you can ask whether the company is leaning towards one option or excluding a set of options completely
• Prep: Have a friend read you case prompts and then practice asking 2-3 clarifying questions on the fly. Try to think of them as you’re taking down notes and giving the recap. Are they helping you with your structuring or are you asking the first thing that pops into your head? Are they broad enough or overly detailed? Are there types of questions you should be asking but keep forgetting?

Framework (4-5 minutes)

Structuring (<2 minutes) : Do not use the word “framework” during the interview. I ask if I could have time to “gather my thoughts” when I am structuring. In your structure, you should have at least three but no more than five “buckets.” These are areas that you want to explore in order to solve the case. In each bucket, there should be at least three sub-bullets. Make sure there is no overlap between the buckets.

• Prep: Time yourself structuring your roadmaps. Be comfortable with recalling the different buckets you should be considering for each type of case and brainstorming sub-bullets for those buckets. It’s okay to go over two minutes when you first start, but as you get comfortable, make sure you are becoming more efficient. For example, as you become more familiar with the buckets, you don’t need to write down every example for the sub-bullets, they will become muscle memory as you recite them out loud. Review the suggested frameworks for the case and take note of whether there are vital topics you keep forgetting or whether there are unnecessary buckets you keep adding. There is no one “right” answer, but your roadmap should enable you to uncover the necessary information to make your recommendation.

Presenting: Introduce the high-level buckets first before diving into each one. You will want to “customize” your framework to the specific case you’re working on. This does not mean creating a custom framework for every single case. You can use the same topics for similar types of cases (but ensure that those topics are relevant - some cases sneakily rule out an entire topic to see if you are paying attention), but you need to make sure that you are using case-specific language and examples when you present. This shows that you are thinking about the specific problem, not just recycling a generic framework. After going through the structure, pause and ask if the interviewer has any questions. Then, give your hypothesis and state which bucket you want to start with by asking for data pertaining to that bucket and why you want it.

• Prep: Present your structures out loud and note whether you are rambling or being case-specific in your language. If you find that your presentation is too long, consider cutting down on the examples or explanations. Be succinct and say enough to get your point across. Don’t just move on to the next case if your presentation falls short. Keep practicing until you feel satisfied and make mental notes for the next case.

Interview “Questions” (10-20 minutes)

For each type of question, you are going to be doing the same things: answering the question, providing insights, conveying how it impacts your recommendation, and driving the case forward. Every time you have “answered” a question, you want to be thinking, “ What else do I need? What’s the logical path forward ?” The only way you can prepare for this is to run through entire cases! Remember, your framework is your friend. Refer back to it often if you don’t know where to go next.

Brainstorming : You will want to structure your ideas into MECE buckets. They can be fairly simple (financials vs. non-financials, external vs. internal, etc.). Similar to your framework, you will give a preview of the buckets first before going into the details of each and you will need to ensure that it is “custom” for your case. If a structure doesn’t naturally come to you, you can create a pseudo-structure by organizing how you will present your brainstorm. For example, you can state how many ideas you have from the onset or say that you will first go through the ideas first and then the associated risks.

This is a highly debated practice, but I always ask for a few seconds so I can think of a structure (they may say no). Don’t take more than 30 seconds because you can add to your buckets as you are presenting.

For non-technical brainstorms, be creative! For example, when interviewers asked about how to increase sales for a consumer-facing retail company, I would bring up TikTok campaigns and celebrity endorsements as a few ideas. Have fun with it!

Occasionally, interviewers will prod you with, “What else?” This does not always mean you didn’t give enough ideas. Sometimes it’s the opposite – they are looking to challenge you or see how you will react. Just roll with it - if you don’t have anything else, say so.

• Prep: Practice brainstorming for different types of prompts. Collect a bank of general ideas and solutions that can be customized for use across industries. Try to think of as many ideas as you can (four to six at the very least) and exercise that creative muscle. To help you with structuring, have a list of “easy” MECE buckets that you can pull out on the fly.

Exhibits : First, give an overview of the exhibit. As an example, for graphs say what the axes represent, tie it back to the case, and give your interpretation of those axes. This gives the interviewer a chance to course-correct if you misinterpreted the exhibit. Give some insight, even if it is low-hanging fruit, and tie it back to the case. There are three levels of insights for both exhibits and math:

• What the numbers say, patterns/trends (X is smaller than anticipated, Y is the largest driver)
• What the client should do (enter the market, cancel plans, plan for launch)
• What we should do next (reconsider something specific, research more data on X, move on to Y)

Oftentimes, exhibits will tie into a calculation. If you are given an exhibit with data that can be used to calculate more insightful information, tell the interviewer that you would like to make those calculations. The interviewer will lead you down that path regardless but it is more impressive if you call it out.

• Prep: Run through different types of exhibits and see how many insights from each level you can pull out. Practice anticipating what type of data you need next in order to move ahead in the case or whether you can/should calculate anything from the data given. Don’t be too insightful though – you only have a limited amount of time to run through the case.

Math : Before you start calculating anything, it is critical for you to confirm what you are solving for and that the information you wrote down is correct. SUPER IMPORTANT – answer the question that is being asked !!  If the interviewer is asking for the incremental profit from a certain strategy, you don’t want to calculate the total profit from the strategy. Active listening is so important!

As you know by now, structure is everything. Again, I always ask for a few seconds to organize my thoughts (the worst thing they can say is no). Set up the problem before you start calculating. This allows you to identify whether there is data missing. Walk the interviewer through your method and ask for missing data. You may need to make your own assumptions or estimates – be sure you can justify them.

If your method is off, the interviewer will usually guide you back to the right path. This saves you from wasting time calculating the incorrect answer. Be sure to pay attention when the interviewer is trying to coach you.

As you are solving the problem, walk the interviewer through each calculation and use math shortcuts as much as possible. Again, if you make a math error, the interviewer can stop you before you go down the entire path. Save time by only calculating what is important for the case and understanding what you can skip.

• Prep: Practice setting up the problem, walking the interviewer through your proposed method, and verbalizing the calculations out loud. On paper, make sure your calculations are being done neatly and not all over the place. Look for different math shortcuts and try them out. Not all of them will fit your style, but you might find new tricks. Track whether you are answering the right questions. Once again, active listening is critical to your candidacy. Once you have correctly solved the problem, make sure you are thinking about the, “So what?” Determine how that number impacts your recommendation and where you should go next.

Synthesis and Recommendation (2-3 minutes)

Again, I always ask for a few seconds to collect your thoughts (<30 secs). If the “CEO is already in the elevator,” they may say no. Have a definitive stance – start with your recommendation and then provide two to three supporting facts using data from the case.

Address risks and next steps (i.e., what is the required analysis/gameplan – this is like real life where the firm is trying to sell additional projects). Your recommendation should be <2 minutes. Frankly, the interviewer has most likely made a decision on your candidacy. Don’t ramble and try to finish strong.

The hardest part of this is pulling out the supporting data in a succinct way. Throughout the case, you should be jotting down notes. I tend to circle what I believe to be relevant supporting data. When you present it, don’t be too specific or granular. You want your recommendation to be punchy.

• Prep: Run through whole cases where you are tracking the relevant supporting data along the way. Time your recommendation and practice verbalizing the information concisely. Don’t forget the risks and next steps. I usually have a list of generic risks (e.g., competitor response, regulation, inaccurate projections) that I can “customize” on the off-chance I’m scrambling to think of some. Your next steps can be collecting additional data to support your recommendation or ways to address those risks.

Final Thoughts

• Your approach is more important than the solution – The interviewer is trying to understand how you think. Some cases have data that support recommendations in either direction. The key piece is that you are able to back your stance using the facts and data uncovered during the interview.
• Deadends are okay – There will be times when you make multiple requests for data and the interviewer does not have it. That’s perfectly fine! You can’t read the interviewer’s mind and the case could go in so many directions. Just look back at your framework to see where else you can proceed.
• Be coachable – It’s not the end of the world if your method is wrong or if you misinterpreted an exhibit. The interviewer wants to see that you are actively listening and can take feedback and improve. Don’t freak out! Stay calm! Listen to what the interviewer is trying to tell you.

This guide only scratches the surface of case interviews. The best way to prepare for case interviews is to get your reps in with entire cases. That way, you can identify your areas of weakness and be more precise with the drills. I can give you feedback and additional tips and tricks so that you are performing at your best on interview day.

How to succeed in a consulting case study interview.

Top consulting firms like Bain, McKinsey, and BCG all assess candidates through case studies, so case study interview prep is essential © Bain & Company via Facebook

Applying for a job at Bain, BCG, or McKinsey? Ex-Bain consultant explains how to approach your case study interview prep and ace the recruitment process

Wed Nov 17 2021

But with the right preparation you can really stand out, and case study interview prep is a good place to start. These five tips will boost your performance from good to great, so you can stand out from the crowd.

1. Understand what’s being asked

This might seem like common sense, but it can’t be emphasized enough.

Many candidates make assumptions when they’re first given the case interview question, and end up spending their time solving the wrong problem.

For example, an interviewer might ask you how you would help a company grow. If you assume ‘growth’ means more revenue, but the interviewer actually meant increased profits or market share, you end up with the wrong solution.

2. Structure your approach

Before you dive in, take a moment to think about how you would solve the problem you're given. 

Your interviewer isn’t looking for the perfect answer to the case. If tough business problems could be solved that easily, the management consulting industry wouldn’t exist. Instead, your interviewer is assessing your ability to break the case into its key components and then to go through these components step-by-step to identify the source of the business problem and its solution. 

This is the same skill that you'll use day to day as a consultant, so interviewers want to see that you can demonstrate this skill.

For more on how to structure your approach to a case interview question, see My Consulting Offer’s Guide to Case Study Interview Prep .

3. Make the interview conversational

As a consultant, you’ll be working directly with other consultants and your clients to solve problems. This problem solving will take the form of discussions, so the interviewer wants to know you can be a great problem solver while still being conversational. 

In consulting, we call this being ‘client-friendly,’ which means being someone a client can trust, not just someone they hire to solve a problem.

You can set a conversational tone right from the beginning of your case by asking pertinent questions when you’re first given the case question. This will draw your interviewer into the case with you. It will also get you some great information to inform your problem-solving.

As you work through your structure and begin to make assumptions,it’s also a good idea to ask whether your assumptions are reasonable. For example, if you’re given a profitability case and need to make an assumption about how much revenues might improve in response to a price cut, make a logical assumption and ask your interviewer for feedback on it. 

Again, this engages your interviewer in the problem-solving process. It will also provide you with useful feedback. 

4. Address any implementation risks in your recommendation

At the end of your interview, you need to tie up your case neatly, with a well-reasoned and persuasive recommendation for the ‘client’—your interviewer.  

What most applicants don’t realize is that you should also address risks that are inherent in your recommendation. 

For example, if you’re recommending the client goes forward with a new product launch, you should note that competitors will see the marketing for the new product and defend their market share. 

They might do this by launching a new product of their own or, perhaps, competing on price. Noting these risks doesn't make your recommendation weaker. It shows you're aware of the competitive environment and allows you to deepen your recommendation by brainstorming ways to fool-proof the implementation plan—thinking through likely scenarios that the client will face.

5. Be ready to be challenged—if you are it’s a good sign

What if you present the results of your analysis or your recommendation and your interviewer tells you she thinks your logic is flawed? 

It might be tempting to think it’s a crisis, or that you’ve just bombed the interview.

But often, that’s not the case. If you screw up, there’s no need for the interviewer to make the interview more difficult. It’s just awkward. But if you’ve done well, your interviewer wants to make sure you can hold up under pressure in front of a client. That’s when you’re likely to get the stress test. The key here is to have confidence. 

Think through the objection they raise. If they have a point, acknowledge it and talk through how you’d modify your analysis or recommendation to address it. If you think that your recommendation is still solid, say so, and why you think that’s the case.

By doing your case study interview prep, and actively incorporating these five tips naturally in your interviews, you’re sure to move to the top of the strategy consulting firms’ applicant pool and get closer to landing an offer.

• The measurable results of the service provided.
• Data and metrics that prove the success of your service or product, if possible.

You can adapt these considerations based on how your customers use your product and the specific answers or quotes that you want to receive.

What makes a good case study question?

A good case study question delivers a powerful message to leads in the decision stage of your prospective buyer's journey.

Since your client has agreed to participate in a case study, they're likely enthusiastic about the service you provide. Thus, a good case study question hands the reins over to the client and opens a conversation.

Try asking open-ended questions to encourage your client to talk about the excellent service or product you provide.

Case Study Interview Questions About the Customer's Business

Knowing the customer's business is an excellent way of setting the tone for a case study.

Use these questions to get some background information about the company and its business goals. This information can be used to introduce the business at the beginning of the case study — plus, future prospects might resonate with their stories and become leads for you.

• Would you give me a quick overview of [company]? This is an opportunity for the client to describe their business in their own words. You'll get useful background information and it's an easy prompt to get the client talking.
• Can you describe your role? This will give you a better idea of the responsibilities they are subject to.
• How do your role and team fit into the company and its goals? Knowing how the team functions to achieve company goals will help you formulate how your solution involves all stakeholders.
• How long has your company been in business? Getting this information will help the reader gauge if pain points are specific to a startup or new company vs. a veteran company.
• How many employees do you have? Another great descriptor for readers to have. They can compare the featured company size with their own.
• Is your company revenue available? If so, what is it? This will give your readers background information on the featured company's gross sales.
• Who is your target customer? Knowing who the target audience is will help you provide a better overview of their market for your case study readers.
• How does our product help your team or company achieve its objectives? This is one of the most important questions because it is the basis of the case study. Get specifics on how your product provided a solution for your client. You want to be able to say "X company implemented our solution and achieved Y. "
• How are our companies aligned (mission, strategy, culture, etc.)? If any attributes of your company's mission or culture appealed to the client, call it out.

How many people are on your team? What are their roles? This will help describe key players within the organization and their impact on the implementation of your solution.

Case Study Interview Questions About the Environment Before the Purchase

A good case study is designed to build trust. Ask clients to describe the tools and processes they used before your product or service. These kinds of case study questions will highlight the business' need they had to fulfill and appeal to future clients.

• What was your team's process prior to using our product? This will give the reader a baseline to compare the results for your company's product.
• Were there any costs associated with the process prior to using our product? Was it more expensive? Was it worth the cost? How did the product affect the client's bottom line? This will be a useful metric to disclose if your company saved the client money or was more cost-efficient.
• What were the major pain points of your process prior to using our product? Describe these obstacles in detail. You want the reader to get as much information on the problem as possible as it sets up the reasoning for why your company's solution was implemented.
• Did our product replace a similar tool or is this the first time your team is using a product like this? Were they using a similar product? If so, having this information may give readers a reason to choose your brand over the competition.
• What other challenges were you and your team experiencing prior to using our product? The more details you can give readers regarding the client's struggles, the better. You want to paint a full picture of the challenges the client faced and how your company resolved them.

Getting answers to this question will illustrate to readers the client's concerns about switching to your service. Your readers may have similar concerns and reading how your client worked through this process will be helpful.
• Why didn't you buy our product or a similar product earlier? Have the client describe any hesitations they had using your product. Their concerns may be relatable to potential leads.
• Were there any "dealbreakers" involved in your decision to become a customer? Describing how your company was able to provide a solution that worked within those parameters demonstrates how accommodating your brand is and how you put the customer first. It's also great to illustrate any unique challenges the client had. This better explains their situation to the reader.
• Did you have to make any changes you weren't anticipating once you became a customer? Readers of your case study can learn how switching to your product came with some unexpected changes (good or bad) and how they navigated them. If you helped your client with troubleshooting, ask them to explain that here.

How has your perception of the product changed since you've become a customer? Get the interviewee to describe how your product changed how they do business. This includes how your product accomplished what they previously thought was impossible.

Case Study Interview Questions About the Decision Process

Readers of the case study will be interested in which factors influenced the decision-making process for the client. If they can relate to that process, there's a bigger chance they'll buy your product.

The answers to these questions will help potential customers through their decision-making process.

• How did you hear about our product? If the client chose to work with you based on a recommendation or another positive case study, include that. It will demonstrate that you are a trusted brand with an established reputation for delivering results.
• How long had you been looking for a solution to this problem? This will add to the reader's understanding of how these particular challenges impacted the company before choosing your product.
• Were you comparing alternative solutions? Which ones? This will demonstrate to readers that the client explored other options before choosing your company.
• Would you describe a few of the reasons you decided to buy our product? Ask the interviewee to describe why they chose your product over the competition and any benefits your company offered that made you stand out.
• What were the criteria you used when deciding to buy our product? This will give readers more background insight into the factors that impacted their decision-making process.
• Were there any high-level initiatives or goals that prompted the decision to buy? For example, was this decision motivated by a company-wide vision? Prompt your clients to discuss what lead to the decision to work with you and how you're the obvious choice.
• What was the buying process like? Did you notice anything exceptional or any points of friction? This is an opportunity for the client to comment on how seamless and easy you make the buying process. Get them to describe what went well from start to finish.
• How would you have changed the buying process, if at all? This is an opportunity for you to fine-tune your process to accommodate future buyers.
• Who on your team was involved in the buying process? This will give readers more background on the key players involved from executives to project managers. With this information, readers can see who they may potentially need to involve in the decision-making process on their teams.

Case Study Interview Questions About the Customer's Business Case

Your case study questions should ask about your product or solution's impact on the customer's employees, teams, metrics, and goals. These questions allow the client to praise the value of your service and tell others exactly what benefits they derived from it.

When readers review your product or service's impact on the client, it enforces the belief that the case study is credible.

• How long have you been using our product? This will help readers gauge how long it took to see results and your overall satisfaction with the product or service.
• How many different people at your company use our product? This will help readers gauge how they can adapt the product to their teams if similar in size.
• Are there multiple departments or teams using our product? This will demonstrate how great of an impact your product has made across departments.

• If other teams or departments are using our product, do you know how they're using it? With this information, leads can picture how they can use your product across their teams and how it may improve their workflow and metrics.
• What was the most obvious advantage you felt our product offered during the sales process? The interviewee should explain the benefits they've gained from using your product or service. This is important for convincing other leads you are better than the competition.
• Were there any other advantages you discovered after using the product more regularly? Your interviewee may have experienced some additional benefits from using your product. Have them describe in detail what these advantages are and how they've helped the company improve.
• Are there any metrics or KPIs you track with our product? What are they? The more numbers and data the client can provide, the better.
• Were you tracking any metrics prior to using our product? What were they? This will allow readers to get a clear, before-and-after comparison of using your product.
• How has our product impacted your core metrics? This is an opportunity for your clients to drive home how your product assisted them in hitting their metrics and goals.

Case Study Interview Questions About the Buying Team and Internal Advocates

See if there are any individuals at the customer's company who are advocates for your product.

• Are there any additional team members you consider to be advocates for our product? For example, does anyone stick out as a "power user" or product expert on your team? You may want to interview and include these power users in your case study as well. Consider asking them for tips on using your service or product.
• Is there anyone else on your team you think we should talk to? Again, the more people can share their experience using your product, the better.
• Are there any team members who you think might not be the biggest fans of our product or who might need more training? Providing extra support to those struggling with your product may improve their user experience and turn into an opportunity to not only learn about their obstacles but turn them into a product fan
• Would you share some details about how your team implemented our product? Get as much information as possible about the rollout. Hopefully, they'll gush about how seamless the process was.
• Who from your company was involved in implementing our product? This will give readers more insight into who needs to be involved for a successful rollout of their own.
• Were there any internal risks or additional costs involved with implementing our product? If so, how did you address them? This will give insight into the client's process and rollout and this case study question will likely provide tips on what potential leads should be on the lookout for.
• Is there a training process in place for your team's use of our product? If so, what does it look like? If your company provided support and training to the client, have them describe that experience.
• About how long does it take a new team member to get up to speed with our product? This will help leads determine how much time it will take to onboard an employee to your using your product. If a new user can quickly get started seamlessly, it bodes well for you.
• What was your main concern about rolling this product out to your company? Describing their challenges in detail will provide readers with useful insight.

• How do you measure the value our product provides? Have the interviewee illustrate what metrics they use to gauge the product's success and how. Data is helpful, but you should go beyond the numbers. Maybe your product improved company morale and how teams work together.

Case Study Interview Questions About Product Feedback

Ask the customer if they'd recommend your product to others. A strong recommendation will help potential clients be more open to purchasing your product.

• How do other companies in this industry solve the problems you had before you purchased our product? This will give you insight into how other companies may be functioning without your product and how you can assist them.
• Have you ever talked about our product to any of your clients or peers? What did you say? This can provide you with more leads and a chance to get a referral.

Case Study Interview Questions to Prompt Quote-Worthy Feedback

Enhance your case study with quotable soundbites from the customer. By asking these questions, prospects have more insight into other clients and their success with your product — which helps build trust.

• How would you describe your process in one sentence prior to using our product? Ideally, this sentence would quickly and descriptively sum up the most prominent pain point or challenge with the previous process.

• Why do you do business with us? Hopefully, your interviewee will share how wonderful your business relationship is.

Before you can start putting together your case study, you need to ask your customer's permission.

If you have a customer who's seen success with your product, reach out to them. Use this template to get started:

Thank you & quick request

Hi [customer name],

Thanks again for your business — working with you to [solve X, launch Y, take advantage of Z opportunity] has been extremely rewarding, and I'm looking forward to more collaboration in the future.

[Name of your company] is building a library of case studies to include on our site. We're looking for successful companies using [product] to solve interesting challenges, and your team immediately came to mind. Are you open to [customer company name] being featured?

It should be a lightweight process — [I, a product marketer] will ask you roughly [10, 15, 20] questions via email or phone about your experience and results. This case study will include a blurb about your company and a link to your homepage (which hopefully will make your SEO team happy!)

In any case, thank you again for the chance to work with you, and I hope you have a great week.

[Your name]

If one of your customers has recently passed along some praise (to you, their account manager, your boss; on an online forum; to another potential customer; etc.), then send them a version of this email:

Hey [customer name],

Thanks for the great feedback — I'm really glad to hear [product] is working well for you and that [customer company name] is getting the results you're looking for.

My team is actually in the process of building out our library of case studies, and I'd love to include your story. Happy to provide more details if you're potentially interested.

Either way, thank you again, and I look forward to getting more updates on your progress.

You can also find potential case study customers by usage or product data. For instance, maybe you see a company you sold to 10 months ago just bought eight more seats or upgraded to a new tier. Clearly, they're happy with the solution. Try this template:

I saw you just [invested in our X product; added Y more users; achieved Z product milestone]. Congratulations! I'd love to share your story using [product] with the world -- I think it's a great example of how our product + a dedicated team and a good strategy can achieve awesome results.

Are you open to being featured? If so, I'll send along more details.

Case Study Benefits

• Case studies are a form of customer advocacy.
• Case studies provide a joint-promotion opportunity.
• Case studies are easily sharable.
• Case studies build rapport with your customers.
• Case studies are less opinionated than customer reviews.

1. Case studies are a form of customer advocacy.

If you haven't noticed, customers aren't always quick to trust a brand's advertisements and sales strategies.

With every other brand claiming to be the best in the business, it's hard to sort exaggeration from reality.

This is the most important reason why case studies are effective. They are testimonials from your customers of your service. If someone is considering your business, a case study is a much more convincing piece of marketing or sales material than traditional advertising.

2. Case studies provide a joint-promotion opportunity.

Your business isn't the only one that benefits from a case study. Customers participating in case studies benefit, too.

Think about it. Case studies are free advertisements for your customers, not to mention the SEO factor, too. While they're not promoting their products or services, they're still getting the word out about their business. And, the case study highlights how successful their business is — showing interested leads that they're on the up and up.

3. Case studies are easily sharable.

No matter your role on the sales team, case studies are great to have on hand. You can easily share them with leads, prospects, and clients.

Whether you embed them on your website or save them as a PDF, you can simply send a link to share your case study with others. They can share that link with their peers and colleagues, and so on.

Case studies can also be useful during a sales pitch. In sales, timing is everything. If a customer is explaining a problem that was solved and discussed in your case study, you can quickly find the document and share it with them.

4. Case studies build rapport with your customers.

While case studies are very useful, they do require some back and forth with your customers to obtain the exact feedback you're looking for.

Even though time is involved, the good news is this builds rapport with your most loyal customers. You get to know them on a personal level, and they'll become more than just your most valuable clients.

And, the better the rapport you have with them, the more likely they'll be to recommend your business, products, or services to others.

5. Case studies are less opinionated than customer reviews.

Data is the difference between a case study and a review. Customer reviews are typically based on the customer's opinion of your brand. While they might write a glowing review, it's completely subjective and there's rarely empirical evidence supporting their claim.

Case studies, on the other hand, are more data-driven. While they'll still talk about how great your brand is, they support this claim with quantitative data that's relevant to the reader. It's hard to argue with data.

An effective case study must be genuine and credible. Your case study should explain why certain customers are the right fit for your business and how your company can help meet their specific needs. That way, someone in a similar situation can use your case study as a testimonial for why they should choose your business.

Use the case study questions above to create an ideal customer case study questionnaire. By asking your customers the right questions, you can obtain valuable feedback that can be shared with potential leads and convert them into loyal customers.

35 Case Interviews Examples from MBB / Big Four Firms

Studying case interview examples is one of the first steps in preparing for the  management consulting  recruitment process. If you don’t want to spend hours searching the web, this article presents a comprehensive and convenient list for you – with 35 example cases, 16 case books, along with a case video accompanied by detailed feedback on tips and techniques.

A clear understanding of “what is a case interview” is essential for effective use of these examples. I suggest reading our  Case Interview 101  guide, if you haven’t done so.

McKinsey case interview examples

Mckinsey practice cases.

• Diconsa Case
• Electro-Light Case
• GlobaPharm Case
• National Education Case

What should I know about McKinsey Case interviews?

At McKinsey, case interviews often follow the interviewer-led format , where the interviewer asks you multiple questions for you to answer with short pitches.

How do you nail these cases? Since the questions can be grouped into predictable types, an efficient approach is to master each question type. However, do that after you’ve mastered the case interview fundamentals!

For a detailed guide on interviewer-led cases, check out our article on McKinsey Case Interview .

BCG & Bain case interview examples

Bcg practice cases.

• BCG – Written Case – Chateau Boomerang

Bain practice cases

• Bain – Coffee Shop Co.
• Bain – Fashion Co.
• Bain – Mock Interview – Associate Consultant
• Bain – Mock Interview – Consultant

What should I know about BCG & Bain case interviews?

Unlike McKinsey, BCG and Bain case interviews typically follow the candidate-led format – which is the opposite of interviewer-led, with the candidate driving the case progress by actively breaking down problems in their own way.

The key to acing candidate-led cases is to master the case interview fundamental concepts as well as the frameworks.

Some BCG and Bain offices also utilize written case interviews – you have to go through a pile of data slides, select the most relevant ones to answer a set of interviewer questions, then deliver those answers in a presentation.

For a detailed guide on candidate-led cases, check out our article on BCG & Bain Case Interview .

Deloitte case interview examples

Deloitte practice cases.

Undergrad Cases

• Human Capital – Capital Airlines
• Strategy – Club Co
• Strategy – Health Agency
• Technology – Waste Management
• Technology – Bank of Zurich
• Technology – Galaxy Fitness

What should I know about Deloitte case interviews?

Case interviews at Deloitte also lean towards the candidate-led format like BCG and Bain.

The Deloitte consultant recruitment process also features group case interviews , which not only test analytical skills but also place a great deal on interpersonal handling.

Accenture case interview examples

Accenture divides its cases into three types with very cool-sounding names.

Sorted in descending order of popularity, they are:

These are similar to candidate-led cases at Bain and BCG. albeit shorter – the key is to develop a suitable framework and ask the right questions to extract data from the interviewer.

These are similar to the market-sizing and guesstimate questions asked in interviewer-led cases – demonstrate your calculations in structured, clear-cut, logical steps and you’ll nail the case.

These cases have you sort through a deluge of data to draw solutions; however, this type of case is rare.

Capital One case interview examples

Capital One is the odd one on this list – it is a bank-holding company. Nonetheless, this being one of the biggest banks in America, it’s interesting to see how its cases differ from the consulting ones.

Having gone through Capital One’s guide to its cases, I can’t help but notice the less-MECE structure of the sample answers. Additionally, there seems to be a greater focus on the numbers.

Nonetheless, having a solid knowledge of the basics of case interviews will not hurt you – if anything, your presentation will be much more in-depth, comprehensive, and understandable!

See Capital One Business Analyst Case Interview for an example case and answers.

Other firms case interview examples

Besides the leading ones, we have some examples from other major consulting firms as well.

• Oliver Wyman – Wumbleworld
• Oliver Wyman – Aqualine
• LEK – Cinema

Case interview example – Case video

The limitation of most official case interview examples is that they are either too short and vague, or in text format, or both.

To solve that problem for you, we’ve extracted a 30-minute-long, feedback-rich case sample from our Case Interview End-to-End Secrets Program .

This is a candidate-led, profitability case on an internet music broadcasting company called Pandora.

In 30 minutes, this candidate demonstrates the exact kind of shortcoming that most candidates suffer during real case interviews – they come in with sharp business senses, then hurt their own chances with inadequate techniques.

Here are seven notable areas where the candidate (and you) can improve:

Thanking Throughout the case, as especially in the opening, he should have shown more appreciation for the time the interviewer spent with him.

Structured opening The candidate’s opening of the case feels unstructured. He could have improved it by not mixing the playback and clarification parts. You can learn to nail the case in a 3-minute start through this video on How to Open Any Case Perfectly .

Explicitness A lot of the candidate’s thought process remains in his head; in a case interview, it’s better to be as explicit as possible – draw your issue tree out and point to it as you speak; state your hypothesis when you move into a branch; when you receive data, acknowledge it out loud.

Avoiding silence The silence in his case performance is too long, including his timeout and various gaps in his speech; either ask for timeout (and keep it as short as possible) or think out loud to fill those gaps.

Proactivity The candidate relies too much on the interviewer (e.g: asking for data when it can easily be calculated); you don’t want to appear lazy before your interviewer, so avoid this.

Avoiding repeating mistakes Making one mistake twice is a big no-no in consulting interviews; one key part of the consulting skill set is the ability to learn, and repeating your mistakes (especially if the interviewer has pointed it out) makes you look like someone who doesn’t learn.

Note-taking Given the mistakes this candidate makes, he’s probably not taking his notes well. I can show you how to get it right if you watch this video on Case Interview Note-Taking .

Nonetheless, there are three good points you can learn from the candidate:

The candidate sums up what he’s covered and announces his upcoming approach at the start and at key points in the case – this is a very good habit that gives you a sense of direction and shows that you’re an organized person.

The candidate performs a “reality check” on whether his actions match the issue tree; in a case interview it’s easy to lose track of what you’re doing, so remember to do this every once in a while.

The candidate prompts the interviewer to give out more data than he asked for; if anything, this actually matches a habit of real consultants, and if you’re lucky, your interviewer may actually give out important pieces you haven’t thought of.

These are only part of the “ninja tips” taught In our Case Interview E2E Secrets Program – besides the math and business intuition for long-term development, a key feature is the instant-result tips and techniques for case interviews.

Once you’ve mastered them, you can nail any case they throw at you!

For more “quality” practice, let’s have a mock case interview with former consultants from McKinsey, BCG, Bain, Oliver Wyman, Strategy& and many other consulting firms. They will help you identify your problem areas and give you actionable feedback, making your preparation much easier and faster.

Hi! This is Kim and welcome to another performance in the Tips & Techniques part of our amazing End-to-end program. You are about to hear a really interesting performance.

There is a common Myth that Profitability cases are easier. Well, for beginners, that’s may make sense, but I would argue that Profitability cases can be really tricky and candidates without good foundation will make about the same level of mistakes regardless of type of cases given.

The profitability case we are about to watch will show that. It’s a very unconventional

Profitability. It started out like a typical one but getting more and more tricky toward the end.

The candidate is fairly good in term of business intuition, but the Tips & Techniques aspect needs a lot of fine tune! Now let’s go ahead and get started! 

It’s actually a little better to playback the case information and ask clarifications. The candidate does not distinguish between the two and do both at a same time. Also, the candidate was asking these clarifications in an unorganized and unstructured fashion. This is not something terrible, but could have been better, especially when this is the very first part of the case, where the crucial first impression is being formed.

My pitch would sound like this:

“That’s a very interesting problem and I am happy to get the chance to solve it. First of all let me tell you my understanding of the case context and key objectives. Then I would like to ask a few clarifying questions regarding a few terminology and concepts. Both of these are to make sure that I will be solving the right problem.

So here is my understanding of the case: The client is ABC. Here are some DEF facts about the situation we just talked about. And the key case question is XYZ.

Does that correctly and adequately summarize the case?”

Once the interviewer confirms, I would move to the clarification part as follows: “Now I would like to ask a few clarification questions. There are three of them: No 1, … No 2, … and No 3, …”

You may see above pitch as obvious but that’s a perfect example of how you should open any cases. Every details matters. We will point out those details in just a second. But before we do that, it’s actually very helpful if you can go back, listen carefully to the above pitch, and try to point out the great components yourselves. Only after that, go back to this point and learn it all together.

Alright, let’s break down the perfect opening.

First of all, you hear me say: “That’s a very interesting problem and I am happy to get a chance to solve it”. This seems trivial but very beneficial in multiple ways:

1. I bought myself a couple of seconds to calm down and get focused. 2. By nature, we as human unconsciously like those who give us compliments. Nothing better than opening the case with a modest compliment to the interviewer.

And (c) I showed my great attitude towards the case, which the interviewer would assume is the same for real future consulting business problems.

You should do that in your interviews too. Say it and accompany it with the best smile you can give. It shows that you are not afraid of any problems. In fact, you love them and you are always ready for them.

Secondly, I did what I refer to as the “map habit”, which is to always say what you are about to do and then do it. Just like somebody in the car showing the drivers the route before cruising on the road. The driver would love it. This is where I said: “Let me tell you my understanding of the case context and key objectives. Then ABC…”.

Third, right at the beginning of the case, I try to be crystal clear and easy to follow. I don’t let the interviewer confused between playing the case vs. asking clarification questions. I distinguish between the two really carefully. This habit probably doesn’t change the outcome of how the case goes that much, but it certainly significantly changes the impression the interviewer has of me.

Fourth, in playing back the case, each person would have a different way to re-phrase. But there are three buckets to always include:

1. Who is the client 2. The facts regarding the client and the situation and (c) The key question and the objective of the case.

Fifth, after playing the case context and objectives, I pause for a second and ALIGN with the interviewer: “Does it correctly and adequately summarize the case?”. This is a habit that every consulting manager loves for young consultants to do. Nobody wants first-year folks to spend weeks of passion and hard-work building an excel model that the team can’t use. This habit is extensively taught at McKinsey, Bain and BCG, so therefore interviewers would love somebody that exhibits this habit often in case interview.

Lastly, when asking clarification questions, you hear me number them very carefully to create the strong impression that I am very organized and structured. I said I have three clarifying questions. Then I number them as I go through each. No.1, No.2, and No.3.

Sometimes, during interviews it’s hard to know exactly how many items you are going to get. One way is to take timeout often to carefully plan your pitch. If this is not possible in certain situations, you may skip telling how many items you have; but you should definitely still number your question: No.1, No.2; and so on. 

Just a moment ago, the candidate actually exhibited a good habit. After going through his clarification questions, the candidate ended by asking the “is there anything else” question. In this case, I actually give out an important piece of data.

Though this is not very common as not every interviewer is that generous in giving out data. But this is a habit management consultants have to have every day when talking to experts, clients, or key stakeholders. The key is to get the most data and insights out of every interview and this is the type of open-ended question every consultant asks several times a day.

To show of this habit in a case interview is very good!

There are three things I would like you to pay attention to:

First, it took the candidate up to 72 seconds to “gather his thoughts”. This is a little too long in a case interview. I intentionally leave the 72 seconds of silence in the recording so you get an idea of how long that is in real situations. But it’s worth-noting here is not only that. While in some very complicated and weird cases, it’s ok to take that long to really think and gather ideas. In this case, the approach as proposed by the candidate is very simple. For this very approach, I think no more than 15 to 20 seconds should be used.

No.2, with that said, I have told I really like the fact that this candidate exhibits the “map” habit. Before going straight to the approach he draws the overall approach first.

No.3. You also see here that the candidate tried to align the approach with me by asking my thoughts on it. As I just said on the previous comment, this is a great habit to have. Not only does it help reduce chance of going into the wrong direction in case interviews, but it also creates a good impression. Consulting interviewers love people doing it often!

Here we see a not-really-bad response that for sure could be much better. The candidate was going into the first branch of the analysis which is Revenue. I would fix this in 3 aspects:

First, even though we just talked about the overall approach, it’s still better to briefly set up the issue tree first then clearly note that you are going into one branch.

Second, this is not a must, but I always try to make my hypothesis as explicitly clear as possible. Here the candidate just implicitly made a hypothesis that the problem is on the revenue side. The best way to show our hypothesis-driven mindset is to explicitly say it.

Third, you hear this a ton of times in our End-to-End program but I am going to repeat it again and again. It is better to show the habit of aligning here too. Don’t just go into revenue, before doing that, give the interviewer a chance to agree or to actually guide you to Cost.

So, summarizing the above insights, my pitch would sound something like this:

“So as we just discussed, a profit problem is either caused by revenue or by cost. Unless you would like to go into cost first, let’s hypothesize that the problem is on revenue side. I would like to look deeper into Revenue. Do we have any data on the revenue?”

And while saying this, you should literally draw an issue tree and point to each as you speak.

There is an interesting case interview tip I want to point out here. Notice how the candidate responds after receiving two data points from me. He went straight into the next question without at least acknowledging the data received and also without briefly analyzing it.

I am glad that the candidate makes this mistakes… well, not glad for him but for the greater audience of this program. I would like to introduce to you the perfect habit of what you should react and do every time you have any piece of data during case interviews. So three things you need to do:

Step 1: Say … that’s an interesting piece of data. This helps the interviewer acknowledge that you have received and understand the data. This also buys you a little time. And furthermore, it’s always a good thing to give out modest compliments to the interviewer.

Step 2: Describe the data, how it looks, is there any special noteworthy trend? In this case, we should point out that revenue actually grew by more than 50%.

Also notice here that I immediately quantified the difference in specific quantitative measurement (in this case, percentage). Saying revenue went up is good, but it’s great to be able to say revenue went up by more than 50%.

Step 3: Link the trend identified back to the original case question and the hypothesis you have. Does it prove, disprove, or open up new investigation to really test the hypothesis? In this case, this data piece actually opened up new investigating areas to test the hypothesis that the bottleneck is within revenue.

My sample pitch for this step 3 would sound like this: “It’s interesting that revenue went up quite a bit. However, to be able to fully reject our hypothesis on the revenue, I would like to compare our revenue to that of the competitors as well.”

Then only at this point, after going through 3 steps above, I ask for the competitors’ revenue like the candidate did.

Notice here that I ended up asking the same question the candidate did. This shows that the candidate does have a good intuition and thought process. It’s just that he did all of these implicitly on his head.

In consulting case interview, it’s always good to do everything as explicitly as possible. Not only is it easier to follow but it helps show your great thought process.
