4 rounds in total: * 1 round with HR (15-30 minutes) * 2 rounds of tech interview (each 1 hour with medium-hard LC, ML questions, system design) * 1 final round (behavioral questions, about 1 hour)

First, you apply and get an OA. If you score well enough (you don't need a perfect score), then you get the interview, where they give you really hard questions. It depends on the interviewer, but someone I knew got an easy string question.

First, there is a brief introduction about the team and the company. Then, the interviewer asked me to give a basic introduction about myself. After that, there was one coding question, which I think should be hard, and it is not a tagged question.
