Case interview examples - McKinsey, BCG, Bain, etc.

One of the best ways to prepare for case interviews at firms like McKinsey, BCG, or Bain, is by studying case interview examples. 

There are a lot of free sample cases out there, but it's really hard to know where to start. So in this article, we have listed all the best free case examples available, in one place.

The below list of resources includes interactive case interview samples provided by consulting firms, video case interview demonstrations, case books, and materials developed by the team here at IGotAnOffer. Let's continue to the list.

5. How to practise case interviews

We've coached more than 15,000 people for interviews since 2018. There are essentially three activities you can do to practice case interviews. Here’s what we've learned about each of them.

5.1 Practise by yourself

Learning by yourself is an essential first step. We recommend you make full use of the free prep resources on our consulting blog and also watch some mock case interviews on our YouTube channel. That way you can see what an excellent answer looks like.

Once you’re in command of the subject matter, you’ll want to practice answering cases. But by yourself, you can’t simulate thinking on your feet or the pressure of performing in front of a stranger. Plus, there are no unexpected follow-up questions and no feedback.

That’s why many candidates try to practice with friends or peers.

5.2 Practise with peers

If you have friends or peers who can do mock interviews with you, that's an option worth trying. It’s free, but be warned, you may come up against the following problems:

  • It’s hard to know if the feedback you get is accurate
  • They’re unlikely to have insider knowledge of interviews at your target company
  • On peer platforms, people often waste your time by not showing up

For those reasons, many candidates skip peer mock interviews and go straight to mock interviews with an expert. 

5.3 Practise with experienced MBB interviewers

In our experience, practising real interviews with experts who can give you company-specific feedback makes a huge difference.

Find a consulting interview coach so you can:

  • Test yourself under real interview conditions
  • Get accurate feedback from a real expert
  • Build your confidence
  • Get company-specific insights
  • Learn how to tell the right stories, better.
  • Save time by focusing your preparation

Landing a job at a top consulting company often results in a $50,000 per year or more increase in total compensation. In our experience, three or four coaching sessions worth ~$500 will make a significant difference in your ability to land the job. That’s an ROI of 100x!
