Initial phone screen with HR Interviewer was very professional. Well spoken. Smart. It was an unscheduled call and started by explaining who he was and why he was calling. Once I agreed that it was a good time the interview began. It lasted for twenty minutes or so. At the end he wanted to know if I had any questions.

Round robin interview with four separate individuals in separate rooms. Each interviewer asked several questions in the span of 30 minutes. Afterwards, I was shown the facility briefly.
