The process took 3 weeks. I interviewed at McKinsey & Company (New York, NY) in Nov 2011
Interview
First rounds at Chicago office - two 45-min interviews with 15-20min behavioral and 25-30 min case. Behavioral is super intense and they'll drill down on the same situation for 15-20 min.
Interviewers clearly more direct than at other firms. Case itself wasn't as hard as other top firms, but McK will push back a lot more and use that as a way to see if you really understand business dynamics.
I interviewed at McKinsey & Company (San Francisco, CA)
Interview
Interview was a straightforward case study, and a McKinsey-specific Personal Experience Interview. This was difficult but I was able to prepare, so it was not too challenging after preparation. The team was very kind throughout the process and I was able to request information on the interview style ahead of time.
Interview questions [1]
Question 1
Tell me about a challenge and how you overcame it?
Passed the online test and then had a round 1 interview. I got a rejection call shortly after. Interviews were a mix of behavioral and technical. Difficulty depends on difficulty of case.
First you get an HR Round, then 2 back to back interviews then 3 interviews. The overall process took around 2-3 weeks, it was not very difficult very fast turnaround
