I applied through an employee referral. The process took 2 weeks. I interviewed at McKinsey & Company in June 2012
Interview
Referred by former Managing Director; set up interview while in town.
Two case questions, one with each interviewer.
One was a profitability issue for various retails branches in various geographic locations.
One was a market sizing question.
Interview questions [1]
Question 1
The profitability issue I found particularly difficult and did not know how to start. However, I chalk this up mostly to not being prepared enough and it shouldn't be THAT difficult if you've done enough case practices.
Straightforward, well structured & well explained. Long duration, with 5 30-ish minute interviews total spread out over the course of a couple of weeks. Great support, information on requirements/evaluations readily available.
Too long - too many rounds. Had to play a game first, then multiple rounds. No follow ups after I was rejected - I got ghosted.
Did not enjoy it - obviously this was a long while back and I was too young to notice but not a good behaviour. Truly no respect.
The process made me feel very unprepared but I was able to get through with all of my studying. I would recommend anyone about to interview with them look at Harvard Business cases as reference
