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.
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

I interviewed at McKinsey & Company (New York, NY)
Interview
Positive experience until the super day. The scheduling was quite long and they gave me a month's gap between my previous round and my final round. But overall everyone speaks eloquently and thinks logically. My interactions with senior partners are also very positive; they ask insightful, probing questions and were encouraging throughout the interview. I thought I smashed it, but one of the partners called me the other day and rejected me.
After submitting my application in their portal. In about two days I recevied the link to do their Solve assessment, The assessment had three games. I was however not selected for the next rounds.
