I interviewed during an open house - was given an interview time that fell after the group presentation time. When I arrived I was given the written exam, then given a copy of the presentation to review while I waited to be called to interview. I jotted a few questions down on the presentation copy, and, at the end of the interview when asked if I had any questions, jotted the answers down. I don't think I've ever been in an interview, aviation or otherwise, where I haven't been asked if I had questions at some point.
