Long. There were 5 30 minute interviews with 5 separate people. Two of the interviews were with possible future peers, both of which were good, one was with the HR director, which was very informative about the company, one was with the upper lever supervisor, which was laid back, however, I had phone screened with him already, and the last was with my future supervisor, which was uncomfortable, due to him asking standard corporate questions that he knew I would not be prepared for.
