It started with an on campus interview with 2 people from the sourcing group - director and associate that was for about 30 minutes. A week later, i got an email being invited for final rounds in Chicago. Final round consisted of an excel test, 4 1x1 interviews that ranged from sourcing managers, 2 directors, and one partner that were about an hour each. The questions were behavioral questions and 2 of the interviews did ask a case question. The last part of the interview was the case study/presentation. you were given a printed out power point presentation for a case and asked to extract information from that and make it into a 3 slide power point and presented it to the same 4 people.
