Four interviews, straightforward typical questions definitely prepare a lot beforehand. Interview process itself was very fast paced and all within two to three weeks I'd say. The first interview was a phone screen with a recruiter, it took about 20 minutes and was just typical questions that were asked. Two days later I got an invite for my first interview, which was with a PM, that was also standard for what I was expecting, that was about 30 minutes. Then two interviews in the final round.
