The interview process started with an initial phone screen. The in person interview was with 4 engineers and HR. All 4 engineers gave me a tests. I was not expecting the interview to be so design related. It was the hardest interview that I have had to date. A couple of the interviewers was really Impersonable. when I would ask them questions that I know I got wrong, one guy would interupt me and say "moving on" and another guy was rolling his eyes at error.
