Just to expand on what Faline2 already said...Alumni interviewers are actually EXPLICITLY told NOT to ask what other schools somebody is applying to unless the student brings it up him or herself. However, it's stated in a powerpoint presentation that you're supposed to read, so perhaps some don't go through it all or choose to ignore it. The questions vary GREATLY from person-to-person as well as the formality. I think wearing khaki's and a button down (no jeans, no suit) is a good rule of thumb and would be suitable for any interviewer. Many applicants wear jeans, which I personally don't care that much about as long as they look presentable, but other interviewers may look down upon. I had one guy show up in a track warmup which seemed odd since he didn't come straight from school...Overall, just be relaxed, be yourself, ask questions, and do your best. The interviewer does write an evaluation on you so I can't say it will have no effect if you make a terrible impression, but typically it's just to get a greater insight into the applicant and doesn't carry much weight. Prepare answers to a few common questions that can be found via a simple google search, including the dreaded "tell me about yourself." Overall, the interview is just as much for you learning more about Duke than it is for Duke to learn more about you.
