The process took 1 day. I interviewed at Oliver Wyman (New York, NY) in Aug 2010
Interview

Interview
First round interview was held on campus - was largely based around previous work experience, relevance and a general understanding of what the role entailed. No case in first round but did as a brain teaser.
Second an final round was a super day in NY with other Ivy league schools. Consisted of a presentation to two partners, a case study and a one on one interview with an Associate.
