A comprehensive 3-stage process. My impression was that the key factors were that your technical knowledge was good and that you would be a good fit for the team and company. The content/focus of each stage was clearly described in each invitation so you knew what to expect. The interactions with the various interviewees were pleasant and relatively relaxed. I felt very comfortable asking questions so I could be sure that the role would be a good fit for me. Decision-making at each stage was the fastest I've ever known and it took just over 2 weeks from application to offer. This was the most pleasant application/interview process I've experienced and the swift decisions were greatly appreciated.
