I had two rounds of interview. One interviewer was friendly but the other one was not. They typically asked about coding questions at median level but the time was very limited for candidates to solve the problems.

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.
