I was interviewed for a full-stack engineering role. The people that I met with were all very kind, but opaque.
Relatively standard interview process - recruiter call, then technical interview with potential peers, then a take-home assignment.
The technical interview was particularly frustrating because the interviewers added extra conditions to it during the interview, then realized at the end that the extra conditions were not part of the assignment.
The interviewers did not review my take-home assignment for more than two weeks.
