First round - 1 case interview with a Senior Manager. Second round 2 case interviews + behavioral with partners and senior partners. Fairly straightforward process and streamlined once it gets going.

Brief screening interview (in person) followed by full-day on-site interview. Interviewed with four consultants who asked a mixture of business, statistics, and brain-teaser type questions. The day culminated with an interview with the section head who did a brief and fairly easy case-style interview.
