Cases should take 15-25 minutes. I've taken a look at this one and, even though it's beginner, it's quite long. I'd say 20-25 minutes.

Hello Marta,
In a real interview you usually have around 30 minutes to solve your case. You have to be really careful to listen to your interviewer during the interview: every case has hundreds ways to be "complicated" by the candidate.
It's good to mention all the critical points that come up to your mind, showing your critical reasoning skills, but always ask the interviewer before getting lost in useless and complex analysis. Most of the times, since you have only half hour, the interviewer will say "Okay, let's assume that.." giving you the solution for that critical point.
Hope it helps,
Luca

Does rejection from the McKinsey and Company case workshop hinder my ability to apply for the open roles in London, and will I be subject to the 12-month waiting period?

Hi I work as a private equity / M&A lawyer in London considering a shift to MBB. My attraction stems from the more commercial / strategic thinking I believe consulting will give me and I can later leverage that to either pivot to (i) industry; or (ii) private equity. Thoughts?
