The process took about 4 weeks.

I applied on their website for the Denver office. I had a phone interview; the interviewer was very nice and made me feel at peace. I did well on the interview and was scheduled for an on-site. I flew to the Denver office.

Had two technical interviews, one pair programming session, and one culture interview. I did well on both technical interviews. However, I didn't do so well on the pair programming one. While it wasn't laid out properly, I didn't ask clarifying questions, and it didn't help that I wasn't familiar with Ruby on Rails (which is what their back-end is in). I did very well on the culture one.
