Help on Alumni Interview Problem!

<p>So I asked for an interview from a School of Computer Science person (Carnegie) like a week ago since I'm applying to SCS, but she didn't respond so I asked someone else from Carnegie Institute of Technology and we set up an interview TOMORROW at 1PM. Now the SCS person JUST replied and I really want to go with the SCS person because I feel that (no 100% sure) it'll help my application tremendously to have someone write my interview on something I can talk about with them (plus there's an essay on the interview so it'd help to have it from someone in SCS) but I feel that it'd be rude to call of the CIT person at the last second. My question is, what do I do? Can I have both interviews? Is that an option?</p>
