Though not as prestigious as McKinsey, BCG or Bain, the Big 4 of accounting are also among the largest management consulting firms out there. 

For a long time, I’ve reveived quite a few questions from my readers on case interviews at Big 4 firms and how they differ from the “typical cases”, with Deloitte being the most frequent subject. So today, I’ll take some time to answer one such question.

Question – Is there anything unique about Deloitte case interviews?

I am having an interview with Deloitte this week. Been following case interview prep for a while now, I can get myself through the basic just fine. I am just wondering what are things I must notice specifically for this Deloitte interview? Is there any worth-noting facts about Deloitte cases that make them different from those at MBB firms?

My philosophy is this: if you really deserve to ace one firm’s case interview, you should also be able to pass all firms’ cases. Otherwise, any single ace is just pure luck!

Now with that said, it does not hurt to come into your Deloitte case knowing the following:
