I applied online through an employee referral. I was invited to an email about 1 week later at the Boulder, Colorado office. 8 people were interviewing the same day. I had 3 interviews each with 2 engineers and each lasted 30 minutes. By the 3rd interview, it was basically all the same questions as from the first two. None of the interviews were with the hiring manager. The process was way too rushed, not very efficient, and I left not really knowing what I would be doing there as an engineer. I had very little time to ask questions. I received an email the day after my interview saying I was not a good fit. The good part about the interview process here is that the whole application, interview and result was done within about 2 weeks.
