1st round interview was at my University, where I met with two people for two, 15 minutes 1:1 interviews. The first one was a simple case study related to the call routing of sales agents. Compared to any other case study, this was by far the easiest. 2nd round was at Red Ventures in Fort Mill where I have 4 half hour interviews. 2 of them were behavioral, and 2 were case. Red Ventures really makes an effort to see if you match with the cultural. The case interview were significantly harder than the 1st round interviews, but not overwhelming. I took the offer and it was a great experience.
