I applied online. The process took 1 day. I interviewed at McKinsey & Company (Chicago, IL) in Oct 2010
Interview
A central aspect of Mckinsey's recruiting process is the case interview, as they believe it most closely parallels the actual work consultants might undertake there. Throughout the recruiting process, I participated in several round of case interviews, each of which varied in scope and approach. I'd say the best preparation for these interviews is to familiarize your self with the process and to practice sample cases with friends or colleagues.
Interview questions [1]
Question 1
What is the potential demand (in units) for anti-cancer drugs in the U/S.? How many cancer patients are there?
Had 2 rounds. First was a virtual interview with 2 sessions back-to-back. One case and one PEI in each. Second was a final in person round, with 3 sessions back-to-back with one case and one PEI each.

Question 1
Tell me about yourself
Behavioral questions - There are only 4 PEIs which are listed in their career prep site
3 step process. first was a screening then followed with around 7 case studies. the case studies ranged in varying industries and scope. this was done over a course of 2 months
Too long, too many rounds, too many people interviewing you and you need to follow up several times in order to get a response. They give you the materials to prepare which is good, but everything else is suboptimal
