Initial interview was an hour with two engineers, discussion and coding exercise. Second round interview was two hours of coding exercises with two engineers, along with another hour with others of interview. All over videoconference/screen sharing.
I messed up the coding interview by being too nervous. There wasn't anything in the exercises that particularly intimidated me -- they were well-crafted exercises, not requiring too much contextual knowledge, the right kind of tasks for this kind of interview. However, I hadn't done interview code exercises like this before, nor do I have much experience pair programming, programming in front of an audience was a new experience for me, and made me pretty nervous especially when I knew I was being evaluated. I was nervous and jumpy, and it showed, and in the feedback given by the recruiter, this was the reason I was turned down, I seemed hurried and not confident.
I guess my advice is do your best to stay calm and collected and one step at a time in code exercises in interviews!
All around, but for that, the interview process was good, relatively speedy, with the interviewers showing care and consideration for the candidate.
