I was contacted by a recruiter and then set up a phone interview using an online programming website. I was asked a couple of technical conceptual questions, followed by a simple algorithm coding question. The total time was about 45 minutes. Noth

The interview lasted four hours. Each round was tougher than the last. We had to build the system in steps over all six rounds. The first four rounds were half an hour each, and the last two were an hour each.

I briefly met with one of the managers and had a behavioral interview. We talked about tech, but did not do any algorithm questions. Once I got past that, I was called in for an interview that lasted about 2.5 hours. I met with other senior managers
