I applied through a recruiter. The process took 1 day. I interviewed at Kearney in Nov 2011
Interview
Recruiter contacted me initially and was very helpful and considerate of my time. My interaction with people at the firm was a 180. Both interviewers were late. And there was no type of warm reception at the office. It seemed like they didn't care if I was there/interested or not.
2 rounds, 5 interviews total. Consisted of 4 cases with some behavioral questions. Final interview with partner only on behaviorals. The whole process was really quick and great, with very accommodating recruiter.
Two round process with one case in the first and two in the second, one behavioral interview in each interview. The cases got progressively easier, and the interviewers offered feedback in between rounds.
Fair interview process. First one is generally with Manager, and final round interview is generally with a Partner. Be prepared for a case! I genuinely enjoyed my final round with the Partner and felt that he was someone I could learn from.
