I had two one-on-one non-technical interviews, which went well. I then had two two-on-one interviews. The first was technical. It was somewhat difficult, but reasonable. The second interview was I guess meant to try to understand my architecture methodology, but was done in such a way that they kept asking general questions that weren't actually answerable, and not giving any feedback on what they were getting at. It was the first time I remember feeling that the interviewers faield the interview process. Not only did I not get the job, they never got back with me.
