I spoke with several interviewers. Although we did speak about my experience in reviewing regulatory documents the questions were not in any depth. They seemed to be more interested in my personality and perhaps my 'fit' for the position within their group.

They put me in a conference room and 5 interviewers took turns coming in the room. Questioning was not intensive but they all asked the same thing. It didn't come across that they were trying to see if I would say the same thing, rather they were just winging it and asking the usual questions. But they made me feel very comfortable and no games.
