Voxel,
I've gotten this at least twice at every programs that I've interviewed at for neuro (11 programs). It's been especially true if I'm speaking to the chair or the program director. At the Cleveland Clinic, I interviewed with 6-7 faculty. My last three interviews began with that dreaded question, "do you have any questions for me?" By that point in the day, I had asked all the residents, and many other faculty members the same questions over and over. It seemed quite pointless.
Other faculty will spend the whole alotted time period talking about the program, telling us it's really up to us to decide whether we want to come to the program or not.
I must say though that my favorite type of interview is the one where the interviewer spends the first 2-3 minutes of the interview getting a first glance at your application. That always gives me a good first impression.
