30 minute interview on-campus to begin. Then four phone interviews that each lasted about an hour. Interviewed on-site for 4-5 hours. First three rounds had zero fit questions, only probability/game theory problems. Final round of on-site involved being given 100 chips and then making markets on answers to problems that were not difficult but very hard to get an exact answer to in the time they give you (1-2 minutes per problem). The interviews were actually pretty enjoyable because the problems were good but I rate my overall experience as negative because I had to go through many rounds of interviews to get to the onsite, which took an entire day of interview and transport, only to be rejected at the final stage.
