I met with four different people in different positions, but in the same R&D department. Since it was a writing position there was a writing sample portion that took thirty minutes. It was helpful not only on their end, but also gave me a good feel of the content I'd be writing. The whole interview took about 2 hours I believe. The interview was laid back and very down to earth. It was a conversation instead of an interrogation. I felt very relaxed and everyone was friendly and gave me lots of information about the job and answered all my questions. The response time was quick after the interview. I interviewed on a Wednesday, and by Monday they had called me back.
