Had 4 rounds of interviews with a particular team (did not get to choose the team) and each lasted for one hour. There was some kind of connection problem so it took about 5 minutes to solve. The first interviewer gave a small introduction and started with two behavior questions. He was very interested in getting to know my answer, so he asked a lot of follow-up questions before finally gave the coding question. The second interviewer started with the coding question and we had about 5 minutes for behavior. The third interviewer was pretty chill compared to the first two. We went through behavior questions like chit chat and then a coding question. The fourth interviewer is the director of the team. He was interested in knowing why I was interviewing with the team, which I actually did not have a choice. There are other teams I would love to join, so I hope in the future, the coordination between HRs and Engineering Teams could be better.
