Practice both interview-led and interviewee-led cases.
Don’t expect an interview to be fully interviewee-led (McKinsey-type) or interviewer-led (BCG-type). Each type demands slightly different skills and interviewers often expect you to both take the lead as well as respond to his/ her specific question in the same interview.

Practise cases with partners and also alone.
When you practise cases alone, it is easier to pay more attention to the quantitative questions (i.e. what numbers you had wrong, shortcuts you could have use, etc.). When you practise with a peer, you get to improve your communication skills and hear other ways of interpreting the same exercise.

How many to crack? As many as you need to feel comfortable. Just keep in mind that it is about developing the skills that help you crack any case – each one is different. Make sure to do cases in depth. Be careful with over practising – it can kill your creativity and fresh style!
