For specifically the on site interview, 2 interviews in the morning, lunch with my second interviewer, 2 more interviews. Each one lasted approximately 45 minutes to an hour, and the interviewers were of very diverse ages and backgrounds, all interesting to interview with though. Lunch included tour of the campus.

1 coding assessment. If you pass, you get to the final round which consists of 4 rounds in one day. 3 technical and one behavioral. The algorithms I had was BFS, Min heaps, and backtracking(parentheses)
