Interviews with department chairs

My school didn't have a psychiatry department chair and I'm unfamiliar with what their role is in the grand scheme of things and what their role would be in my potential future life as a resident at their institution. I've had interviews with them, but they feel like wasted opportunities that I fumble through by making small talk. I even asked one to help me get a sense of his role and he said, "Oh, meetings mostly." What are some useful things for me to ask or for me to have in mind to notice during these interviews?
