The process took 4 weeks. I interviewed at McKinsey & Company in Jan 2012
Interview
One month after I applied on the internet site, HR contacted me to schedule the first round and emailed me some docs that I found really useful to prepare myself. The first round consisted of a written test followed by a 1:1 interview. The written test was very similar to one that I had received in the email.

Question 1
Why does a haircut cost much more money today than in the sixties?
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.

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.
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.
