I am in Canada, but I am applying to schools in the US and obviously I am not fully familiar with the process; how embarrassing! I assumed that the professors interviewing me would be the ones who would be accessing me for whether I would be a good candidate for their lab in particular and didn't consider that this may simply be the admissions committee. If these individuals are simply accessing me for whether I would be a good fit for their program in general, I find it a bit odd that I wouldn't have the opportunity to chat one-on-one with the professors I'm actually interested in doing rotations with. However, I suppose there will be other opportunities during lunch, poster sessions, etc. where I could speak with them.
By "professors I'd actually be working with", I meant that the individuals I'll be interviewing with aren't those I proposed to do rotations with, as their research is quite different from my previous experience and research interests. So far no one has mentioned anything about who I'd actually be doing rotations with, likely because this is a discussion to be had if they decide to give me an offer of admission, as you advised. I haven't actually contacted any professors in this program directly yet, but my SOP was very detailed and my application included a list of the professors whose research I was interested in. I think you're right in that this is likely the admissions committee interviewing me and not necessarily my prospective PIs.
Thank you so much for clarifying this process with me; you have great advice that I'll certainly be following and questions that I'll be asking!
