Interview
There are 3 rounds to the interview process: phone screening (30 min), one online (30 mins), and a final round (in person, 45 mins). Fairly standard questions behavioral questions they asked during all rounds. Not many technical questions. If they did ask it would be very simple like what is a binary tree. Mostly behavorial and resume review
