It was the most enjoyable interview I have had. I'm only a student so don't have much interview experience, but I really enjoyed the experience. There were 4 interviewers (they are all essentially managers for one of the software teams) and they were all very friendly, and helped me feel comfortable. The interview was about an hour, maybe less. All of the questions seem relevant, and most were just describing past work experience on my resume. They also showed me around the office after which was enjoyable. I haven't gotten an offer yet, but they haven't told me no yet either(the interview was last Wednesday, so 6 days ago).
