I was referred by a friend who was employed there, and had a phone screen. After a fair amount of followup with their internal recruiter, I was brought in for an onsite. During the onsite I interviewed with a few engineers, had lunch with some of the team and met with their recruiter to discuss salary (before being made an offer).

The process began with a skills based phone screening. The screening was fair and thorough, and the interveiwer was appropriately forgiving about minor mistakes. The interview generally felt more like a friendly conversation, and it was very easy to relax and honestly express my knowledge and personality. Following the screening, I was flown to San Francisco for an on-site interview with a total of four potential team members, an HR representative, and my would-be supervisor (who had conducted the original screening). It was one of the fairest and most well-conducted interview processes I've ever been through. Everyone was extremely easy to get along with, and again it was perfectly easy to relax and be myself.
