One shared document programming screening interview. On-site day was four rounds: two whiteboard programming rounds which were moderate, one system design round which was hard, one research q&a session along with behavioral questions. Everybody was very friendly and the process was efficient.

7 Interviews, didn't receive an offer after the final round. Time-consuming process, which includes multiple rounds of technical interviews (design, coding, behavior, etc.) and a 1-hour research talk. The team leader was unpleasant to interact with.
