Case interview tips

Cases can help us assess a candidate across multiple dimensions, and your answers should project clear thinking, practical judgment, and a professional demeanor. Apply this five-step approach while working through the case interview:

  • Understand the issue; ask clarifying questions as needed
  • Identify the underlying assumptions
  • Summarize specific issues and findings
  • State your recommendations
  • Outline next steps and expected results/impacts

We want candidates to have an effective and enjoyable case discussion so we encourage you to follow the case interview tips below. You are not expected to provide the "right" answer, but rather clearly convey your logic and thought process. Sample case interviews provide examples and mimic an actual case dialogue.

To help you demonstrate your best thinking in the case interview, we encourage you to:

  • Take notes throughout the case exercise
  • Be sure you understand the case question
  • Ask questions, but don't use them as a crutch—we're interested in how you connect the dots, not in painting the picture for you
  • Develop and articulate a framework and the initial hypothesis that you intend to explore
  • Take time to compose your thoughts–don't just start talking
  • Structure your analysis into a clear, logical story
  • Walk the interviewer through your thinking and explain your assumptions
  • Don't panic—engage the interviewer in a business conversation
  • Don't forget that the case interview is an opportunity to learn about a Deloitte project

Below are examples of the kinds of questions you could be asked at different stages of the intern and graduate recruitment processes at Deloitte - and how to show recruiters, in your answers, that you possess the competencies they're looking for. Even if the questions you're asked are different, practising how you'd answer these will be great preparation for your interview.

Why Deloitte?

How to approach the question: Employers always tell students to use examples in their interview answers, and this is no different. You can demonstrate your commercial awareness and career motivation by giving a couple of examples about what Deloitte is currently doing.

The points you make should show that you have thoroughly researched the company – simply referring to Deloitte’s annual turnover or first quarter results doesn’t really say very much and won’t make you stand out from the competition. You can still cite these results, however, as long as you talk about what they mean. Think about other recent developments – for example, how will Deloitte’s recent acquisition of Market Gravity impact the firm's consulting business? Explain how these developments are relevant to you and your interests.

Don’t say: Anything to do with a ‘strong reputation for excellence’, ‘the chance to work with pioneers in their fields’, ‘working within a true meritocracy’ or anything that sounds equally sycophantic.

If you were running Deloitte for a day, what would you do?

How to approach the question: Deloitte is looking for someone who can make and implement clear decisions, and has exceptional planning and organisational skills. You will likely face follow-up questions that challenge your opinions; your interviewer will play Devil’s advocate to make sure you have considered things from every angle.

You could suggest, for example, that you would identify a number of areas for the business in the technology sector. If you gave an example, you would have to consider the potential impact on Deloitte’s other geographical markets and additional service lines, as well as the long term impact on business development in these areas.

Don’t say: You would make wholesale changes and focus only on one or two markets alone. The example above highlights the technology sector, but remember to think about how your actions here impact on the rest of the business. You can easily fall into the trap of focusing only on what you are interested in, rather than what’s in the best interests of the international business as a whole.

What challenges is Deloitte currently facing?

How to approach the question: This is a particularly fun question because you can really sell yourself in terms of what value you could bring to Deloitte and highlight your commercial awareness. The best place to start is the 'Newsroom' section of Deloitte's website. You need to take some company news and spin it around to relate to what you do. Just relaying a piece of news that the recruiters are already aware of isn’t enough; you need then to be able to say, ‘What this means for the company is x’, and, even better, ‘This is what it means for the division I’m applying to, and how it might affect things we have to consider here in Britain’.

Don’t say: That the current economic climate makes things difficult for Deloitte. You’ll need to know plenty about local, national and international economics, certainly, but this is the bare minimum – you need to be more specific.

What does the ACA (or another professional qualification) involve?

How to approach the question: Everyone is going to go to Deloitte’s webpage and note down its content. The problem with this is that Deloitte’s website doesn’t actually provide much information about the ACA qualification, aside from the absolute basics. A more interesting candidate would investigate the providers of the ACA qualification and find out who Deloitte’s specific training partners are. Contracts for this kind of training vary quite a lot in the industry, so it’s useful to keep up to date with the different partnerships. The content of the ACA will always stay the same, but how it is taught and how much personal study is involved will vary, so look into this to help your answer.
