That seems a bit harsh, especially if the interview is the last thing you do on interview day. I know that when I interviewed there were times when I would be asked "any more questions?" and I had just spent the last 5 hours asking questions, including in other interviews and tours and meet and greets that I had already done that day. I came up with a generic question that I would ask every interviewer, but I seriously would not hold it against someone if they didn't have any questions left for me, so long as they seemed like human beings during the interview and not drones. Though if the interview is first thing I would be a little bit more wary.
Yeah I can relate to this. In general I felt like if I was going to get rejected because I didn't have any questions at the end of my interview, it wasn't a great interview anyway. I personally get irritated when people force stupid questions just to show they have thought about the school. I think there are other ways to put your best foot forward and show thoughtfulness and curiosity about a school. I actually recall, for probably the biggest interview of my life so far (not med school), that I was asked at the end if I had any comments or questions. While many of the other interviewees had already admitted to each other that they'd prepared either little speeches for the end or general questions crafted to show some attribute they wanted to leave the committee with, I honestly answered that I had none and felt comfortable with what had been discussed at that time. The panel all perked up in their seats and exchanged looks with one another, and one person even remarked "Well
that's certainly a first!". I actually felt crushed and thought I had tanked the interview by being honest, but I actually ended up being successful.
That was a long-winded story basically to say that I really advocate approaching interviews with honesty. Certainly put your best foot forward, but avoid getting caught up in games. If I have questions remaining, I'll ask them. If I don't, I'll thank them and explain that my questions had already been answered. Maybe this only works for people who are good conversationalists or interviewers. Perhaps it's stubbornness, but believe enough in yourself and in your performance in the interview that you don't have to worry about every perceived slight or misstep that an interviewer might imagine. You can't know all their preferences and cues, and focusing on them could force you into situations where you no longer approach interviews with authenticity and honesty, which is often very detectable (and certainly not beneficial). The hell with it, just do you.
Caveats:
1) Definitely ask questions if you have some, often there are questions that you have remaining that just weren't on the top of your head so think about this ahead of time. For most interviews I did have questions.
2) Be ready to accept the consequences
