In general, the interview process was interesting, engaging, and fair. There were multiple stages (personal essay, basic testing, a take-home coding assignment, and several in-person interviews), but all felt fair and respectful. The people on the other end were engaging and interested, and the communication throughout the process was good (I never felt left wondering what the status was). The only negative I found was that the process was long in terms of actual calendar time from application to offer. But there was an unexpected benefit there as well: by the time they made an offer, I had spoken with ~6 different people and gotten a much better view into the corporate culture. The longer process helped me interview the company.
