I applied through a recruiter. The process took 4 months. I interviewed at McKinsey & Company (Lagos) in May 2013
Interview
I wrote and passed the Problem Solving Test. I was then selected for the 1st round of interviews. I had a coaching session with one of the analysts. On the day of the Interview, I was put through two interview sessions for the 1st round and each of them was an hour on average. First was a one on one live session, the other was also through video conferencing.
Interview questions [2]
Question 1
Describe a time when you disagreed with a teammate, what happened, what did you do and how was it resolved?
What challenges have you faced with any of your teammates while working as part of a team, what happened, what did you do (i.e did you seek advice), how was it resolved?
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
