I applied online through Door of Clubs, which linked me to their website. I heard back a week later asking to schedule my first round technical phone interview. We used CoderPad - the interview went well, the interviewer was really nice and the question was difficult, but definitely solvable. After this interview, I heard back the next day to schedule the second round interview of 2 back-to-back Skype interviews. Again, both interviewers were super nice and the questions were difficult, but solvable. I thought I did well on these interviews, but I was not called back for a third round.
