I applied through college or university. The process took 2 weeks. I interviewed at Kearney in Sep 2013
Interview
Two rounds -- first round 2 45 minutes interviews with a case each. Second round - 1 case where you are left in a room for 1 hour to prepare and present to 2 consultants. 2 individual interviews after that with or without case depending on interviewer. Typical cases from MBA case workshops, nothing unique
I applied through a recruiter. The process took 3 months. I interviewed at Kearney (Prag) in Nov 2008
Interview
Expect at least 5 interviews, I myself had an interview with approx. 8 people. Every one has the right to refuse you. People are evaluating your approach to the problem: whether you are able to invent process how to get to solution. Plus, they evaluate whether you are nice person to work with, for example, whether they would be OK spending with you more time with you than their family during the project.
