My experience was different than most, because I was selected to be interviewed during the holiday season, so there was a large gap between all the interviews. But I believe, regardless, the process is the same. There was a total of 5 interviews, each roughly an hour long. The first was with an engineer to determine whether or not you would move forward. After moving on to the next stage, there was a call with a recruiter, where they explained what happens next and what to prepare. Finally, there were 4 back-to-back interviews with three engineers and a hiring manager. The engineering interviews all contained a live coding session, where they gave you a problem to solve. After it was all done, I had to wait roughly 2-3 days for the team to meet up and make their decision.
