4 interviews: 1) Group interview (10 people in total), including 4 "quick" tests (reading, logic, maths, english skills) and a group assignment to discuss and reach a joint conclussion 2) HR interview, with a background check 3) Technical interview with your (hopefully) future direct boss 4) Last interview with a Partner (high-rank boss in the internal hierarchy)

I applied through a school website and had an hour long campus interview, two 30-minute interviews with local managers. It was a standard fit-interview. Final rounds were at the office, totaling about 4-5 hours, including lunch and other activities that HR puts on. Two senior employees, including one partner, interview you for 30 minutes each. Another standard fit-interview. Candidates were extended an offer a couple hours after the final rounds on the same day.
