The first interview was with the Director of Operations only. It was fairly brief and conversational. To be honest, because there were no tough questions, I left thinking that they were really not interested in me.
The second interview was about 3 weeks later, and was entirely informational; again, no questions. I'd been scheduled to speak with the manager I was to work with, but he was too busy. I met with a different manager who told me a bit about the firm and his work style. It would have been better if I'd been able to speak with my manager-to-be, as it turned out that our expectations of each other and my position were not quite aligned, and the first few months there were a bit rough.
