The process took 1 day. I interviewed at McKinsey & Company in Feb 2009
Interview
People very incredibly friendly throughout and did a great job explaining what to expect from the interview beforehand. Phone interview consisted of behavioral questions (20 minutes) and a case (approx 40 minutes). Be prepared to talk about yourself and handle a challenging case.
Interview questions [1]
Question 1
The case dealt with an expansion strategy for a small firm in a market with which I wasn't familiar. The interviewer had plenty of information available and was helpful. Tip: when they ask you, "Do you have anything more to say?", you need to think of additional ideas.
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
