The process was: an initial meeting with a recruiter, then a take-home challenge, then two hour-long systems design challenges, and an hour-long coding challenge. The interviewers varied in quality since it was a different person for each thing. The girl who asked me about the nexflix challenge was very confusing and kept changing the instructions, but the rest of the interviews were fun. That was also my first one so I was really nervous. I think they should validate their interviewers a little bit more. The feedback I got on other two interviews was good and I did miss something really obvious in the last systems design one now that I look back at it.
