• Hacking the Case Interview

Deloitte case interviews are the most difficult part of the interview process. Deloitte interviews are comprised of case interviews, a group case interview, and behavioral or fit interview questions. You will need to pass every single Deloitte case interview in order to land a job offer.

Deloitte Interview Process

The Deloitte interview process typically consists of two rounds of interview that include case interviews, a group case interview, and behavioral or fit interview questions. The entire interview process can take anywhere from one week to a few months.

Given its size, Deloitte may have a different interview process depending on the country or the office that you are interviewing for. However, the most common interview process consists of two rounds of interviews following the submission of your Deloitte resume .

• First round interviews : you will have one 30 to 45-minute behavioral interview and one or two 30 to 45-minute case interviews.
• Final round interviews : you will have a 30 to 45-minute behavioral interview, a 30 to 45-minute case interview, and a one hour group case interview

There are three important distinctions between your first round Deloitte interview and your final round Deloitte interview.

One, your interviewers will likely be more senior people at Deloitte. This means that the case interviews you receive may be a bit less structured and more qualitative in nature. The case interview may feel more like a discussion where you and the interviewer are discussing your opinions and ideas on a business problem.

Two, there will be more of an emphasis on assessing your fit with the firm. The first round interview is primarily used as a screener to determine whether or not you can solve case interviews effectively and whether or not you have the potential to be a great consultant.

Final round interviews will also continue to assess this, but interviewers will also be determining whether or not you would be a great fit with the office. Are you coachable and easy to work with? Are you collaborative? These are a few of the qualities that interviewers want to see.

Three, your interviewers may read the notes that your interviewers wrote during your Deloitte first round interview. If there was a particular area of the case interview that you struggled with, interviewers may want to test you again on it to make sure that it is not a significant weakness.

What is a Deloitte Case Interview?

A Deloitte case interview, also known as a “case” for short, is a 30 to 60-minute exercise in which you and the interviewer work together to develop a recommendation or answer to a business problem.

These business problems can be anything that real companies face:

• How can Amazon increase its profitability?
• What can Apple do to increase customer retention?
• How should Tesla price its new electric vehicle?
• Where should Disney open another Disneyland theme park?

Deloitte case interviews simulate what the consulting job will be like by placing you in a hypothetical business situation. Cases simulate real business problems that consulting firms solve for their clients. Many Deloitte case interviews are based on actual projects that interviewers have worked on.

While consulting projects typically last between 3 to 9 months, case interviews condense solving the business problem into just 30 to 45 minutes.

Deloitte case interviews can cover any industry, including retail, consumer packaged goods, financial services, energy, education, healthcare, government, and technology.

They can also cover a wide range of business situations, including entering a new market, launching a new product, acquiring a company, improving profitability, and growing revenues.

Although Deloitte case interviews cover a wide range of industries and business situations, no technical or specialized knowledge is needed. Unless you are interviewing for a consulting firm that specializes in a particular industry or function, cases are designed to be solved by someone that has general business knowledge.

Nailing your Deloitte case interviews is critical to get a job at Deloitte. There is no way to get a Deloitte job offer without passing your case interviews.

What Does a Deloitte Case Interview Assess?

Deloitte case interviews assess five different qualities or characteristics: logical and structured thinking, analytical problem solving, business acumen, communication skills, and personality and cultural fit.

1. Logical and structured thinking : Consultants need to be organized and methodical in order to work efficiently.

• Can you structure complex problems in a clear, simple way?
• Can you take tremendous amounts of information and data and identify the most important points?
• Can you use logic and reason to make appropriate conclusions?

2. Analytical problem solving : Consultants work with a tremendous amount of data and information in order to develop recommendations to complex problems.

• Can you read and interpret data well?
• Can you perform math computations smoothly and accurately?
• Can you conduct the right analyses to draw the right conclusions?

3. Business acumen : A strong business instinct helps consultants make the right decisions and develop the right recommendations.

• Do you have a basic understanding of fundamental business concepts?
• Do your conclusions and recommendations make sense from a business perspective?

4. Communication skills : Consultants need strong communication skills to collaborate with teammates and clients effectively.

• Can you communicate in a clear, concise way?
• Are you articulate in what you are saying?

5. Personality and cultural fit : Consultants spend a lot of time working closely in small teams. Having a personality and attitude that fits with the team makes the whole team work better together.

• Are you coachable and easy to work with?
• Are you pleasant to be around?

All of these five qualities can be assessed in just a 30 to 60-minute Deloitte case interview. This is what makes case interviews so effective in assessing consulting candidates.

How to Solve Deloitte Case Interviews

Deloitte case interviews are candidate-led. You will be in the driver’s seat of the case interview and will be expected to ask the right questions, probe for data, and propose each next step to solve the case.

In a Deloitte case interview, you are not assessed on whether or not you have the correct answer. Instead, Deloitte uses case interviews to assess six different qualities:

• Problem solving : Can you decompose a problem into smaller, more manageable questions?
• Analytical ability : Can you draw the right insights from data and information?
• Strategic thinking : Do you have a sharp business acumen and practical business judgment?
• Logical thinking : Are you structured, organized, and rational in the way that you think?
• Creativity : Can you generate interesting or unique ideas and solutions?
• Professional demeanor : Are you calm, confident, and articulate?

Our step-by-step guide to case interviews is presented in the video below. We highly recommend watching that video in its entirety. 

On Deloitte's case interview website , they recommend taking five   steps to solve a case interview:

1. Understand the issue and ask clarifying questions

The most important part of the case interview is to make sure you understand the business issue and the objective of the case. The quickest way to fail a case interview is to answer or address the wrong business problem. 

Therefore, if either the business issue or objective of the case is unclear, make sure to ask clarifying questions.

2. Identify the underlying assumptions

Next, you’ll need to decompose the overall business problem into smaller, more manageable issues. Identify what would need to be true in order for you to recommend a particular course of action.

To do this, it will be helpful to put together a framework, which is a tool that helps you organize your ideas and thoughts into different categories. For a complete guide on how to create tailored and unique frameworks for each case, check out our article on case interview frameworks .

3. Summarize specific issues and findings

Afterwards, you’ll begin investigating different issues or areas of your framework. After investigating each one, it is important that you summarize the key takeaways or insights that you uncovered.

Connect these findings back to the overall business problem and explain how your findings impact your potential recommendation.

4. State your recommendations

Once you have gathered enough evidence and support for your recommendation, you will need to present your recommendation in a clear and concise way.

Start by giving a firm recommendation. Then, provide the three major reasons that support your recommendation. This should summarize most of the important findings from the case.

5. Outline next steps and the expected results or impact

After delivering a recommendation, you should propose potential next steps that you would take if you had more time or data. What would you need to know to further strengthen your recommendation or make you more confident in your answer?

You can also talk about the expected results or impact of your recommendation. This may also have implications on potential next steps, such as analyzing the risks or quantifying the financial benefits. 

The Different Types of Deloitte Case Interviews

There are three different types of Deloitte case interviews, one type for each of Deloitte's consulting groups:  

• Strategy & Operations : primarily focused on corporate strategy, supply-chain improvement, business model transformation, and process improvements. The work that this group does is most similar to the work that McKinsey, BCG, and Bain do
• Business Technology : primarily focused on digital strategy, delivery of information technology programs, and building tech-based solutions for clients
• Human Capital : primarily focused on organization transformation, change management, corporate learning and development, and diversity and inclusion

The type of case that you get depends on what group you are interviewing with. 

For example, If you are interviewing with the Strategy & Operations group, you’ll get a strategy or operations case . You may be asked to determine whether to enter a new market, launch a new product, or make an acquisition.

If you are interviewing with the Technology group, you’ll get a technology or IT case. You may be asked to determine whether to roll out a new IT system, how to assess different technologies, or how to best coordinate an IT transformation.

If you are interviewing with the Human Capital group, you may be asked to determine the optimal organization structure, how to better incentivize employees to perform better, or how to save payroll costs.

  Deloitte Case Interview Tips

Below are eight of Deloitte's case interview tips to help you improve your case interview performance.

Tip #1: Take notes

While the interviewer is providing you with the case background information, take notes on the most important pieces of information. Pay particularly close attention to the context, company, and case objective.

Tip #2: Make sure you understand the case question

Answering or addressing the wrong business problem is the quickest way to fail a case interview. The most important thing is understanding what the business issue is and what overall question you’ll be expected to answer at the end of the case. 

Tip #3: Ask questions

Do not be afraid to ask questions. You will not be penalized for asking questions that are important and relevant to the case. 

Great questions to ask include asking for the definition of an unfamiliar term, asking questions that clarify the objective of the issue, and asking questions to strengthen your understanding of the context or company.

Tip #4: After you develop a framework, develop an initial hypothesis

A hypothesis is an educated guess on the answer based on the data and information that you have so far. It helps guide your analysis and keeps you on the right track.

After developing a framework, try to develop a hypothesis to help you decide what area of your framework you should explore first.

Tip #5: Take time to structure your thoughts

When asked a question in a case interview, don’t always start answering immediately. Instead, take the time to process the question and develop an organized and structured way to answer it. It is acceptable to ask the interview for a brief moment to collect your thoughts.

Your answer will likely be much stronger if you give yourself time to think. 

Tip #6: Present a clear, logical story for your recommendation

Remember that consultants need to convince clients to follow their proposed recommendations. Being articulate and persuasive are necessary skills for consultants.

When you deliver your recommendation, try to make it a coherent story. This will make your recommendation easier to follow and more compelling.

Tip #7: Walk the interviewer through your thinking and explain assumptions

You do not get any points for the ideas and thinking that you do not communicate. Therefore, you should make every effort to talk through your thoughts out loud.

Walk the interviewer through what you are thinking. Explain why you have made particular decisions. State your assumptions. This makes it easier for the interviewer to provide feedback or hints to help you out.

Tip #8: Engage the interviewer in a business conversation

Remember that a case interview is a collaborative exercise. You should not be dismissing the feedback and suggestions that the interviewer provides you. They may be trying to help steer the case in the right direction or provide you with hints when you get stuck.

Treat the interviewer as your teammate and turn the case interview into a business conversation.

How to Prepare for Deloitte Case Interviews

There are seven steps to preparing for Deloitte case interviews.

1. Understand what a case interview is

The first step in preparing for Deloitte case interviews is to understand exactly what case interviews are.

When you are familiar with what case interviews are, it is important to know what a great Deloitte case interview performance looks like.

Knowing what a great Deloitte case interview performance looks like will facilitate how quickly you learn case interview strategies in the next step.

Before continuing onto the next step, you should be familiar with:

• The overall objective of a case interview
• The structure and flow of a case interview
• The types of questions you could get asked
• What a great case interview performance looks like

2. Learn the right strategies

Now that you have sufficient background knowledge, the next step in preparing for Deloitte case interviews is to learn the right strategies to build good case interview habits.

It is much more effective to learn the right case strategies the first time than to learn poor strategies and try to correct them later.

The quickest, most efficient way to learn these strategies is to go through our Comprehensive Case Interview Course .

If you prefer reading case interview prep books instead, the three I recommend are:

• The Ultimate Case Interview Workbook
• Case Interview Secrets

Hacking the Case Interview provides strategies on exactly what to do and what to say in every step of the case interview. It is a concise and straight to the point guide. I recommend this book as the first book to read for beginners.

Case Interview Secrets teaches core concepts such as the issue tree , drill-down analysis, and a hypothesis driven approach. It illustrates these concepts through stories and anecdotes. If you have read Hacking the Case Interview, I recommend also reading this book to get perspectives from a second author. Check out our full review of Case Interview Secrets .

Case in Point provides a ton of specific and complex frameworks. However, you likely won’t be using many of these in an actual case interview because many of them are overly complex and specific. If you have time, it may be useful to skim through this book. Check out our full review of Case in Point .

At the bare minimum, read either the first or second book. If you have the time, read the first two books so that you can get strategies from two different authors.

Make sure to spend sufficient time learning the right strategies before starting to practice cases. It is ineffective to practice cases if you have no idea what strategies to practice and refine.

Before moving onto the next step, you should at least have strategies for the following parts of a case interview:

• Developing unique and tailored frameworks
• Solving quantitative problems
• Answering qualitative questions
• Delivering a recommendation

3. Practice 3-5 cases by yourself

Once you have learned the right strategies, the next step in Deloitte case interview prep is to practice.

When practicing case interviews, it is usually better to practice with a case interview partner than to practice by yourself . Casing with a partner better simulates the real case interview experience.

However, when you are just starting to practice, I recommend doing the first 3 – 5 cases by yourself.

There are three reasons for this:

• You can get the hang of the case interview structure and format much more quickly working by yourself rather than having to wait to schedule a time with a partner
• There are many aspects of case interviews that you can practice without a partner, such as structuring a framework and solving quantitative problems. You can get much more practice working through these parts by yourself
• You may have difficulty finding a case interview partner if you are a complete beginner. Without having done any cases, you likely won’t know how to properly give a case or provide good feedback

4. Practice 5-10 cases with a partner

The next step in preparing for Deloitte case interviews is to case with a partner.

Casing with a partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to improve on unless you practice live with a partner.

When practicing cases with a partner, ensure you are spending enough time after cases to deliver feedback.

For a case that takes around 30 – 40 minutes, spend at least 15 – 20 minutes for feedback. Much of your learning and improvement will come from these feedback sessions.

Do not move onto the next step until you have done at least 5 – 10 cases and are beginning to feel comfortable with case interviews.

5. Practice with a former or current consultant

At this point, I highly recommend asking former or current consultants to give you a practice case. This will significantly help you prepare for case interviews.

Doing a mock case with a former or current consultant is highly advantageous because they know exactly how to run cases and give feedback. You’ll receive incredibly helpful feedback that your previous case partners likely missed.

If you feel that you are plateauing with your case partner, that is a sign you should do a mock case interview with a former or current consultant.

You can find former or current consultants among:

• People you met during the consulting recruiting process
• Your broader LinkedIn network

I would not ask a consultant that is involved with the consulting recruiting process for a case too prematurely. Although these practice cases are not evaluative, some firms will actually make note of how well you perform during the practice case.

At this point, you will have accumulated a long list of improvement areas from all of the different people you have cased with.

6. Work on your improvement areas

In this step of preparing for Deloitte case interviews, you will work on strengthening and fine-tuning your improvement areas. Examples of common improvement areas include:

• Creating a more complete and mutually exclusive framework
• Performing math calculations quicker or more smoothly
• Providing more structure to your qualitative answers
• Leading the case more proactively
• Delivering a more succinct recommendation

Try to focus on improving one thing at a time. This is much more effective than trying to improve everything at once.

For some areas, such as math, it will be better to work independently. For other areas, such as learning to proactively lead the case, it will be better to work with a case partner.

If you are looking for more cases, look at the resources listed in step four. If you are looking for specific drills or practice problems for a particular part of a case interview, check out The Ultimate Case Interview Workbook .

Do not move onto the next step until you have finished working on all of your improvement areas.

7. Stay sharp

If you have progressed this far, congratulations! You have almost finished preparing for Deloitte case interviews.

Once you feel that you have no more improvement areas to work on, the key is to not burn yourself out by doing too many unnecessary cases.

While each case that you do makes you slightly better, there is a point when doing too many cases can create case fatigue right before your interview. Case fatigue can negatively impact your interview performance.

On the other hand, you also don’t want to go weeks without having done a case. You may end up forgetting strategies or become rusty and slow.

Once you have achieved case mastery, I recommend doing no more than 2 cases per week in the weeks leading up to your interview. This ensures that you remain sharp for case interviews, but don’t have case fatigue.

How to Solve the Deloitte Group Case Interview

Deloitte is one of the few consulting firms that uses group case interviews in their final round of interviews. They conduct group case interviews because Deloitte’s work culture has a huge emphasis on teamwork and culture fit.

Here’s what to expect:

• You’ll be put into a group with 3 to 5 other candidates
• The interviewer will hand out case materials
• You’ll be given 10 minutes to review the case materials and prepare
• The group will have a discussion for 20 minutes
• During this discussion, interviewers will be observing candidates and will not interfere
• Afterwards, the interviewer will ask the group specific questions for another 20 minutes

Group case interviews can be challenging to prepare for because it is difficult to replicate the exact conditions to practice them. However, if you prepare for case interviews well, you will be in a great position to succeed in group case interviews.

Your goal in a group case interview is to add value to the group. There are six different ways that you can add value:

• Lead or facilitate the discussion : You can propose what topics to discuss, the order they should be discussed in, and how much time should be allocated towards each topic. If the group gets off track, you can bring the group’s focus back together.
• Expand upon other people’s ideas : If a group member suggests a great idea or raises a good point, build upon it and make it even better.
• Synthesize information : You can summarize information that other people have said and reconcile different viewpoints and ideas together.
• Keep track of time : You can volunteer to keep track of time and make sure that the group is on track.
• Play devil’s advocate : You can help your group develop strong ideas by testing the team’s thinking by considering potential risks or downsides of their ideas.
• Take notes:  You can keep track of what other people are saying so that you can recall what has been discussed if any group members have questions.

Follow these five tips to shine during your Deloitte group case interview.

Tip #1: Treat your group members as teammates, not competition

The group case interview is not an exercise in which you are competing with others. Interviewers are trying to assess whether you would be a great teammate. Multiple people or even all people in your group can receive job offers.

Therefore, focus on adding value to the group rather than making yourself look better than your teammates.

Tip #2: Don’t speak too much, but don’t speak too little

If you speak too much, this may be seen as being too aggressive or controlling. If you speak too little, you may come off as shy or timid.

If you were to rank all of the members in your group by how much each person spoke, you would want to be roughly in the middle. This would be the perfect balance of speaking and listening.

Tip #3: Don’t interrupt or talk over your group members

Interrupting others when they are speaking is rude and disrespectful. You do not want to be inconsiderate or a jerk. Be nice and respectful to your group members.

Tip #4: Involve other people

If you observe that someone has not spoken much, ask them for their thoughts or opinions. If you notice that someone has been cut off when they were speaking, ask them to finish their thoughts after the person interrupting them has finished what they have to say.

These are easy ways to show interviewers that you are a considerate and helpful teammate.

Tip #5: Speak only if you are adding value to the group

Just because you are speaking a lot during the group case interview does not mean that you are doing well. Interviewers are not assessing you purely on the quantity of what you say. They care more about the quality.

Great teammates know when to speak and when to listen. Therefore, you should speak only if you are adding some kind of value to the group. Interviewers can tell when people are speaking for the sake of getting air time.

Deloitte Behavioral and Fit Interview Questions

In addition to case interviews, you will likely be asked a few behavioral or fit interview questions. There are ten questions that are most commonly asked.

1. Why Deloitte?

How to answer: Provide your three biggest reasons why you’re interested in working at Deloitte. You could mention that you loved the people that you have met from Deloitte so far. You can talk about Deloitte’s massive global presence, their expertise in nearly any industry or function, or their professional development opportunities.

2. Why consulting?

How to answer: Again, provide three reasons for why you’re interested in consulting. You could mention the fast career progression opportunities, the learning opportunities to develop soft and hard skills, or the level of impact that you can make right away in consulting.

3. Walk me through your resume.

How to answer: Provide a concise summary of your work experience, starting with the most recent. Focus on emphasizing your most impressive and unique accomplishments. At the end, tie your experiences to why you are interested in consulting and why you would be a great fit for Deloitte.

4. What accomplishment are you most proud of? 

How to answer: Choose your most impressive, unique, or memorable accomplishment. Structure your answer by providing information on the situation, the task, the actions you took, and the results of your work. Explain why the accomplishment is so meaningful to you and what qualities that reveals about you as a person.

5. Tell me about something that is not on your resume.

How to answer: This is a great opportunity to highlight an accomplishment that is not related to your professional work experience. Perhaps there is a non-profit that you volunteer at, a side project or business that you work on, or a hobby that you have won awards or recognition for. Select an accomplishment that is impressive and interesting.

6. Tell me about a time when you had to lead a team.

How to answer: If possible, choose a time when you directly managed a person or a team. For this question and the following similar questions, make sure that you structure your answer. Provide information on the situation, the task, the actions you took, and the results of your work. This is known as the STAR method and is the most common way of answering behavioral or fit interview questions. 

7. Describe a time when you faced conflict or disagreement.

How to answer: When answering this question, focus on emphasizing the steps you took to resolve the conflict or disagreement. Speak about the interpersonal skills you had to use in order to mediate the situation. Interviewers want to know that you can handle conflict in a constructive way.

8. Give an example of a time when you successfully persuaded someone.

How to answer: Choose a time when you were able to change someone’s mind who originally disagreed with you. Focus on emphasizing the steps that you took to persuade that person and what impact this had on the organization. Interviewers want to know that you are a great communicator and have strong people skills.

9. Tell me about a time when you failed.

How to answer: Choose a time when you failed to meet a deadline or did not meet expectations. You do not want to pick a failure that is too big or embarrassing. Focus on emphasizing what you learned from the experience and how you used that experience to deliver even better results in the next opportunity that you got. Interviewers want to see that you strive to learn from your past failures and are always working to get better.

10. Are there any questions that you have for me?

How to answer: This is a fantastic opportunity to get to know the interviewer on a more personal level. Ask them questions about their experience in consulting. Ask what their favorite case was or what they are looking to do next in their career. The more you can get the interviewer talking about themself, the more likely they will be to have a positive impression of you. People love talking about themselves, so make sure to listen attentively and ask follow-up questions.

For a step-by-step guide on how to best answer all of these questions and more, check out our complete guide on consulting behavioral interview questions .

Deloitte Case Interview Coaching

With case interview coaching, you’ll pay anywhere between $100 to $300 for a 40- to 60-minute mock case interview session with a case coach. Typically, case coaches are former consultants or interviewers that have worked at top-tier consulting firms.

Although very expensive, case interview coaching can provide you with high quality feedback that can significantly improve your case interview performance.

For case interview beginners and intermediates, it may be a better use of their money to first purchase a case interview course or case interview prep book before purchasing expensive coaching sessions.

If you do decide to eventually use a case interview coach, consider using our case coaching service .

There is a wide range of quality among coaches, so ensure that you are working with someone that is invested in your development and success. If possible, ask for reviews from previous candidates that your coach has worked with.

The Deloitte Case Interview: What to Expect

Deloitte Group Case Interview

Have an interview with Deloitte Consulting coming up? If so, you’ll want to know what to expect and how to prepare.

We’ve got you covered, including our 6 tips on how to ace your Deloitte case interview!

In this article, we’ll discuss:

• What the Deloitte Consulting case interview process looks like,
• The Deloitte case interview: what to expect,
• Sample Deloitte case interviews,
• Our 6 tips on acing the Deloitte case interview,
• The Deloitte group case interview, and
• The Deloitte behavioral interview question.

Let’s get started!

What the Deloitte Consulting Interview Process Looks Like

Initial application.

The Deloitte Consulting interview process has 4 steps:

• Application
• Online assessment
• First round interviews
• Final round interviews

If you’re a student, make sure you know if you need to apply directly to Deloitte Consulting or through your career center.

As part of your application, you’ll need to submit your resume and, for campus hires, your academic transcript. Research which office you want to apply for as you’ll need to state that at this stage.

Deloitte Online Assessment

The second stage of the Deloitte Consulting recruitment process is an online assessment. This assessment tests numerical reasoning and your situational judgment.

Information from recent candidates suggests there are 35 questions split over 5 distinct sections. We’ve got all you need to know about this part of the process in our article, Deloitte Online Assessment: What It Is & How To Pass .

Deloitte Consulting First Round Interviews

If you’re selected for a Deloitte interview you’ll be contacted via your campus career center or direct by the Deloitte recruiting team.

For campus hires, first-round interviews often take place on campus and include one or 2 interviews. These interviews include both case and behavioral interview questions. We’ve heard the cases include market-sizing as well as the non-profit sector.

The same types of interviews are used for non-campus hires.

Deloitte Consulting Final Round Interviews

Final round interviews may take place virtually, on campus, or in a Deloitte office. While the exact format depends on the position you’re applying to, expect both behavioral and case interviews at this stage. Candidates may also have a group case interview.

Deloitte will let you know the outcome of your application within a week of the final round interview.

Case interviews can feel daunting for many candidates. In this section, we’ll cover what type of cases Deloitte uses and how to approach them so you can feel confident in tackling them.

What Exactly Is a Case Interview?

A case interview is an interview conducted within a business context.

The interviewer will present information about a company and a business problem it faces. These 2 elements together are known as a case.

Case interviews can either be candidate-led or interviewer-led depending on who is expected to steer the order in which different aspects of the case are analyzed.

Deloitte case interviews are predominantly candidate-led which means they’ll be looking to you to take control of solving the case — breaking down the problem, choosing a suitable business framework, and asking for appropriate data to fill in the gaps.

What Type Of Cases Does Deloitte Consulting Use?

The branch of Deloitte Consulting you are applying for can influence the business context you receive in the case. There are 3 parts to Deloitte Consulting:

• Strategy and Operations (S&O) focuses on corporate issues such as organizational strategy, supply-chain improvement, operating model transformation, and business process improvements.
• Technology Consulting focuses on technology issues such as digital strategy, IT program delivery, infrastructure and software solutions, and cybersecurity.
• Human Capital focuses on people issues such as organizational transformation, cultural change, knowledge management, and talent acquisition and development.

So, if you were applying for a Human Capital role you might get an organizational transformation case or, if you were applying to S&O you might get an organizational strategy case

Whichever branch you’re applying to, there are going to be certain skills Deloitte Consulting is looking to test through the case interview process.

What Skills Is Deloitte Consulting Looking to Assess?

Deloitte uses case interviews as a way to assess skills it values in its consultants.

• Structured problem solving
• Analytic skills
• A balance of creativity and practicality

Structured Problem Solving

The ability to carefully think through a problem in a structured and logical way, is a key skillset for consultants. You’ll need to be able to break down a business problem to identify and analyze root causes and potential solutions.

Case interviews test this skill by providing lots of data for you to manage within an unfamiliar business context. Your ability to sort through information to pull out what’s most relevant to the issue will be assessed.

Analytic Skills

Deloitte Consulting will assess your numerical ability during the case interview. Make sure you brush up on your math skills in advance of the interview. Our article on Case Math tells you what to expect.

A Balance of Creativity and Practicality

Case interviews give Deloitte recruiters a chance to see how creative you are when searching for an answer to a thorny problem. Clients hire consultants to solve complex, multi-factor problems, not for mundane issues they can solve themselves.

However, innovative thinking needs to be balanced with good business sense. Suggesting solutions that aren’t viable or attractive to the client shows you lack practical business judgment.

Whatever your recommendation, make sure you highlight the risks associated with it and how those could be managed.

Case interviews can feel challenging — very like tackling a real-life client problem! They’re the perfect environment for interviewers to see how comfortable you are with ambiguity and how resilient you are when things get tough.

Whether that’s grappling with a tricky calculation, or struggling to see how the pieces fit together, make sure you don’t give up. Take a breath and give yourself a moment to clear your head. Then jump back in and keep going.

How Do I Tackle a Deloitte Consulting Case Interview?

There are 4 key stages to tackling any case interview:

• Opening . Make sure you fully understand the client’s problem. Repeat back to the interviewer your understanding of the issue so they have a chance to guide you if you’ve misunderstood. Ask any clarification questions you need.
• Structure . Brainstorm all the issues or factors related to the client’s problem that need to be considered. Be explicit about any underlying assumptions you are making to check their accuracy with your interviewer. Organize your thoughts into a logical sequence to make sure you tackle all of them in your analysis.
• Analysis . Gather and review all the data available to you. Data can be communicated directly by your interviewer or come in the form of exhibit. Complete any calculations required. Identify the most important issues and use this to formulate a recommendation.
• Conclusion . Present your findings to the interviewer and give your final recommendation. State any risks associated with the recommendation and how you’d mitigate them. Outline the next steps and the expected result of taking them.

For more information on using these 4 steps to tackle case interviews see Our Ultimate Guide to Case Interview Prep .

Once you’ve got the 4 stages nailed, it’s time to practice! Doing the thinking is only half the battle in a case interview, you’ve also got to effectively communicate your thoughts.

Practicing with friends, people in your network who are also going through the process, or with former consultants who can coach you through it, is critical to your confidence and success.

Links to Sample Deloitte Case Interviews

You can find links to several Deloitte case interviews in our Case Interview Examples article, as well as dozens of cases from other major consulting firms. The Footloose example has a lot of data exhibits so it’s a good one for practicing how to effectively manage information.

In addition, Deloitte has a very helpful tool on their site that helps you practice case interviews. Each of these cases is 15–20 minutes long and presents you with a real-life business problem and a number of questions.

You can prepare your answers to these cases then compare your thoughts to the Deloitte model answers provided.

Our 6 Tips on Acing the Deloitte Case Interview

Tip 1: keep organized notes.

Deloitte case interviews can last up to an hour and have a lot of information to review. Make sure you take organized notes throughout so you don’t forget anything important or miss something in your analysis.

Neat and logical notes also show you can manage large amounts of data effectively.

Tip 2: Ask Questions to Fill In the Gaps

It’s important to fully understand the problem you’re trying to solve. Don’t be afraid to ask clarification questions or for more data to fill in any gaps in your analysis. Asking questions gives the interviewer insight into how you’re approaching the problem.

Tip 3: Take Time to Organize Your Thoughts

Make sure you take your time during the interview to compose yourself and structure your thoughts. It’s tempting to launch into responding straight away but give yourself space to think through your answer first to make sure you don’t miss something or forget an important point.

Tip 4: Utilize a Framework and Develop a Hypothesis

Using a business framework or an issue tree helps you drill down into the heart of the problem. This means you’re more likely to develop a hypothesis that solves the key issue the client is facing.

Keep referring back to your issue tree and hypothesis during your Deloitte interview to make sure your analysis is logical and hasn’t gone down a rabbit hole!

Tip 5: Structure Your Recommendation

Present your analysis in a clear and structured way. Start with the main takeaway — your recommendation. Then walk your Deloitte interviewer through your analysis in a logical way, highlighting the most important points and explaining how they led you to draw the conclusion you have.

Share any assumptions you’ve made to reach your recommendation and also any associated risks. This shows you’ve thought more broadly about the problem in the context of the business as a whole.

Tip 6: Don’t Forget to Breathe!

While case interviews can feel daunting, try not to panic. Viewing the case as a business conversation that showcases your ability to think through a problem, rather than as something that must be solved, can ease the pressure.

As part of the final round assessment, Deloitte Consulting uses group case interviews.

As many of the top consulting firms don’t use group case interviews, candidates can be unsure of what to expect. But, don’t worry, we’ve got you covered!

What Happens In the Deloitte Group Case Interview

In Deloitte group case interviews you’ll be organized into a group with 3-6 other candidates. The group will be presented with information about a case that they’ll need to work together to solve.

• For the first 10 minutes, you’ll work alone, or in a pair, to review the information and prepare your thoughts.
• The group will then discuss the problem for 20 minutes, sharing analysis, and preparing a recommendation for the client. During this discussion, interviewers will observe the group to see how you interact with each other.
• For the final 20 minutes, interviewers will ask questions of the group.

Our Top Tips for the Deloitte Group Interview

Group case interviews are your opportunity to stand out against other candidates. Interviewers will be observing the group dynamics and looking for great communication skills, strong analysis, and leadership.

Here are our top tips:

• Add value with your contribution . Everyone knows interviewers are looking for participation but it’s not enough just to speak up during the group case interview — what you say matters. Your contribution should add fresh insights to what’s already been said. This shows good listening and analysis skills.
• Showcase your leadership ability . Leadership isn’t just about speaking first or dominating the conversation. Facilitate the conversation and bring other team members into the discussion if they haven’t had a chance to speak. This shows you value the contribution of others, which links to one of Deloitte’s core values: foster inclusion . Do be proactive about proposing points for discussion, managing time, and bringing the group back on track if you lose focus.
• Recognize others as teammates . While demonstrating leadership is important, it’s equally important to remember you’re trying to deliver value to the client. Make contributions that bring the group closer to a recommendation — don’t sidetrack the discussion just to stand out. Acknowledge the great ideas of others — which shows confidence — and then add to them.
• Summarize the discussion . At the end of the group discussion, summarize the main points of the conversation and state the group’s recommendation. You can also do this throughout the interview, any time when a lot of points have been discussed and a quick recap would be helpful.

This is important as it shows good communication skills and the ability to synthesize large amounts of data. It also makes sure that everyone’s on the same page and clear about the next steps, which is critical when dealing with real-life clients.

Deloitte Consulting Behavioral Interview Question

The Deloitte behavioral interview has 2 types of questions: fit questions and personal experience questions.

Fit questions help interviewers judge whether you’d fit into the Deloitte culture. Personal experience questions help them judge whether your skills and personal qualities match those they’re looking for in a consultant.

Top 3 Fit Questions and How To Ace Them

1. Why Do You Want To Work For Deloitte Consulting?

This is the top fit question and for good reason. Deloitte Consulting cares about recruiting people who really want to work there and value its specific culture and approach. 

Consulting firms invest heavily in developing their new recruits and they need you to stay long enough to make that investment worth it. So they’re expecting you to join the firm with eyes wide open.

Tackle this question by having a few good reasons why Deloitte is the company for you. The best answers are personal to you. 

Maybe you’ve been inspired by someone you’ve met from the firm. Or there’s something about Deloitte core values that really matters to you. That’s what recruiters want to hear about.

Deloitte Consulting’s core values are:

• Lead the way
• Serve with integrity
• Take care of each other
• Foster inclusion
• Collaborate for measurable impact

2. Why Consulting?

Consulting can be intense, so consulting firms are genuinely concerned that you understand what’s required of you and have the potential to meet the challenge. This question is your chance to explain why consulting is the career for you.

Whether that’s because you get to work with senior management early in your career or you’re excited about the opportunity to make a difference, make sure you’re clear on your motivation.

3. Tell Me Something About You That’s Not On Your Resume.

It’s easy to curate a polished, professional profile on paper. But interviewers are interested in who you are outside of work too.

This question provides an opportunity for you to talk about something you’re passionate about, and show a more human side. Bear in mind the Deloitte Consulting core values when you’re considering how you’d tackle this question.

For example, maybe you organize a community garden to provide food to local families. Or you spend time as a reading volunteer at your local care home.

Contributions you make as a volunteer can demonstrate your leadership capability as well as other ways you create a positive impact in your daily life.

Personal Experience Questions And How to Approach Them

A typical personal experience question starts with “Tell me about a time when…”

They help the interviewer see how your experience has helped you build the skills that make you suitable for consulting.

Examples include:

• Tell me about a time you disagreed with someone and how you worked through the problem.
• Tell me about a time when you led a team to solve a problem.
• Give me an example of when you had to deal with adversity. How did you resolve it?
• Tell me about a time when you changed someone’s mind on an important topic.
• How did you go about deciding on your class project recommendation?

The best approach to tackling a personal experience question is to tell stories. Stories are engaging and stick in the interviewer’s mind even after a long day.

However, like everything else in the case interview, your answer should be well-thought-through and structured. Don’t just launch into your story without thinking.

We recommend using the A STAR(E) framework to make sure your story is impactful and covers all the main points.

Using the A STAR(E) Framework

The A STAR(E) framework covers the following points:

• Answer . Start with a clear, short answer to the question.
• Situation . Give your story some context. Who were the people involved in the story? When and where did it take place?
• Tension . What was the problem you faced? The conflict or challenge?
• Action . What action did you take to resolve the issue?
• Result . What happened as a result of your action?
• Effect . What did you learn?

The (E) is in parentheses because this won’t be relevant to every story.

Remember the behavioral interview is also an important opportunity to learn more about Deloitte so you can feel confident you’re making the right choice.

In fact, that’s one of 6 key things Deloitte Consulting encourages candidates to bear in mind when tackling the behavioral interview:

• Share personal experiences to illustrate your critical skills and achievements.
• Describe experiences and career/life periods reflected in your resume.
• Focus on the positives of all your past experiences and remain optimistic.
• Use this discussion to learn more about Deloitte Consulting.
• Relax, be yourself, and help us get to know you.
• Use your time wisely; it’s your time, make sure you get your points across.

Case Interview Examples (2024): A Collection from McKinsey and Others

Last Updated on January 11, 2024

Whenever you prepare for case interviews, you have to practice as realistically as possible and mimic the real case study interview at McKinsey , BCG , Bain , and others. One way to do this and make your preparation more effective is to practice real cases provided by the firms you apply to.

It will help you to understand what the differences are across firms, how they structure and approach their cases, what dimensions are important to them, and what solutions they consider to be strong.

Below is a steadily expanding selection of real case interview examples provided by different management consulting firms.

Before wasting your money on case interview collection books that use generic cases, use original cases first. Additionally, use professional case coaches, who interviewed for the top firms , to mimic the real interview experience and get real, actionable feedback to improve.

Please be aware that cases are just one part of a typical consulting interview. It is equally important to prepare for behavioral and fit interview questions .

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.

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 .

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.

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.

Initiation: The process kicks off with candidates submitting their resumes and cover letters online, presenting an opportunity to showcase their academic achievements and relevant professional experiences.

Expectations: Beyond the academic and professional qualifications, Strategy& is keenly interested in applicants who embody the five core traits integral to the firm's values.

2.   Online Assessments:

Introduction: Adopting PwC's online assessment methodology, this stage involves a trilogy of evaluations: a numerical reasoning test, a games-based assessment, and a video interview.

Timeline: The assessments, spanning over 2 hours, are strategically spread across a 4-week period, offering a comprehensive evaluation of candidates' analytical abilities and suitability for consulting roles.

3. Super Day Style Interviews:

Format: Strategy& introduces a 'super day' style for interviews, streamlining the evaluation process.

First-Round Interviews (Morning): Led by junior consultants, the first round consists of two interviews. It commences with a 15-minute Personal Fit Interview, followed by a case interview question. Prompt feedback and decisions regarding the afternoon session are provided at the end of the morning.

Second-Round Interviews (Afternoon): Senior consultants, including partners and directors, conduct two interviews mirroring the first-round format.

Outcome: Post-second round interviews, candidates receive detailed feedback or, in the case of successful candidates, a coveted job offer.

​ 4.  Final Decisions:

Closure: The application process concludes with candidates receiving conclusive feedback or, for those who have demonstrated exceptional potential, a formal job offer from Strategy&.

In aligning its application process with PwC's online assessments, Strategy& emphasizes a holistic evaluation approach. The 'super day' structure not only expedites the interview process but also ensures candidates receive timely feedback, enhancing the transparency and efficiency of the recruitment journey. This multi-stage process underscores Strategy&'s commitment to identifying and nurturing top-tier talent to further solidify its position as a global leader in strategy consulting .

• 4. Types of Interviews

Strategy& has  two interview formats across their network:  experience/fit questions followed by a case interview question and experience/ fit questions followed by a structured case interview .

• 4.1 Case Interview (Question)

Real-life Scenarios: Strategy& structures its case interviews around real-life client examples. Interviewers often draw from their own client engagements, leveraging familiarity with data and context.

Attributes Assessed:

Approach and structure

Analytical and creative thinking

Application of data

Communication skills

Business acumen

Evaluation Criteria: Success in a case interview is gauged based on a candidate's proficiency across these attributes, determining their capability to fulfill the responsibilities of a Strategy& consultant.

• 4.2 Experience Interview

Preliminary Insights: Conducted prior to the case interview, experience questions delve into a candidate's motivations, past experiences, and decision-making skills.

​Sample Questions:

Why are you interested in Strategy&?

Why are you interested in consulting?

What experience are you most proud of?

What experience do you wish you could do over, and how would you do it differently?

What is a difficult decision you have made in the last year?

What is an example of a time when you showed initiative and leadership?

What aspects of your internship did you like less?

What do you most like to do in your free time?

What attributes would you bring to a case team?

Describe a role where you changed the direction of a team. How did you do it?

Key Strategy: Structuring responses to these questions is crucial, showcasing a thoughtful and strategic approach even when discussing non-business-related topics.

• 4.3 Case Interview (Structured)

Information Pack: In this structured case interview, candidates receive a 15-20 page information pack and 10 minutes to read it. They formulate three high-level questions they wish to address. The interviewer leaves during this reading period.

Evaluation Focus: Similar to traditional case interviews, the emphasis is on evaluating a candidate's decision-making process, considering trade-offs, and assessing the robustness of recommendations.

• 5. Case Interview

Structured Approach: Strategy& follows a well-defined structure for case interviews, reflecting the core elements of the consulting process.

• Situation and problem:   Understanding the context and defining the problem.

Hypothesis validation:  Offering an initial hypothesis and explaining the intention to validate it.

Framework development: Creating a structured framework for analysis.

Root cause analysis: Exploring the framework to identify the root cause of the issue.

Mathematical calculation (sometimes): If relevant, incorporating mathematical calculations.

Creativity test (sometimes): Demonstrating the ability to think creatively and propose alternatives.

Recommendation: Synthesizing findings and providing a clear and concise proposal.

The Strategy& interview process is a nuanced journey, designed to holistically evaluate candidates' analytical prowess, strategic acumen, and adaptability to the intricacies of strategy consulting. This multifaceted assessment requires candidates to navigate real-life scenarios, draw on experience-based insights, and showcase structured problem-solving abilities.

At the inception of the case interview, the scenario is unveiled by the interviewer, presenting a tangible challenge.

An example might be:

"A high street retailer seeks to reduce costs by 30% in response to the Covid-19 pandemic. How would you approach this?"

Candidates embark on this journey by formulating an initial hypothesis, articulating their intention to validate or refute it. Subsequently, a meticulously crafted framework is developed to guide the analysis, adhering to the MECE (Mutually Exclusive, Collectively Exhaustive) principle. Successful exploration of the framework unveils the root cause of the client's issue, allowing for relevant calculations.

The creativity test introduces a layer of complexity, requiring candidates to propose alternatives when faced with client constraints.

For example:

"The client opposes store closures; suggest alternative cost-cutting measures."

This test is iterative, assessing the candidate's ability to think creatively and adapt solutions as per evolving constraints. Culminating the process, candidates synthesize their findings into a clear and concise recommendation, showcasing their ability to distill complex analyses into actionable proposals.

The Strategy& interview process is not merely a gauntlet; it's an opportunity for candidates to demonstrate their strategic thinking and problem-solving prowess in a simulated consulting environment.

• 6. Additional Tips
• 6.1 Fast Maths

Case interviews are pressurized situations where your anxiety levels are heightened and you don’t have the safety net of notes or the internet to fall back on.

For in-person interviews, it is common that one of the questions will have a mathematical element or be a market sizing question included. These require long maths calculations without a calculator . If you haven’t practiced long addition, multiplication, division, or subtraction recently then it is a good idea to do so. Being quick at maths shows your competent quantitative skills and reduces unnecessary pressure during the interview, increasing your overall performance.

• 6.2 Practice

As with maths, practicing case interviews is the best way to improve your performance . Through practice, you will begin to develop a robust approach that satisfies the structure and framework components of the case and you will recognize how to navigate the case successfully.

If you are applying to Strategy& then you are probably applying to other strategy consulting firms too, this practice will be relevant to all the firms you apply to as they all use case interviews in their application process.

• 6.3 Apply Structure to Everything

The key requirement of a candidate in a case interview is the application of structure , specifically with a MECE approach. As mentioned above, you can even apply structure to the FIT questions and it is recommended you do so.

An example answer to the question ‘walk me through your CV’ would be to segment your experience into: 1) Experience relevant to consulting 2) Experience not relevant to consulting and then briefly cover the experience you have in each bucket. This shows you understand what consulting is and what is relevant and also a key skill of a consultant – structured thinking.

If you can demonstrate robust structured thinking in your interview , you will score highly.

• 7. Conclusion

In conclusion, the Strategy& consulting case interview process is a well-structured journey emphasizing analytical skills, strategic thinking, and adaptability . The firm's integration with PwC brings a comprehensive evaluation approach, focusing on values like integrity and teamwork. The 'super day' style interviews efficiently assess candidates, led by both junior and senior consultants.

The case interview follows a defined structure, challenging candidates with real-world scenarios and time-pressured tasks . Success requires mastering fast maths, consistent case interview practice, and applying a structured approach.

Overall, it's not just a hurdle, but an opportunity for candidates to showcase their abilities in line with Strategy&'s commitment to excellence and innovation in global strategy consulting.
