This was my last interview, but I was still nervous because of the panel format. It was extremely relaxed and informal and I felt like the people I interivewed with were very friendly and non-competitive. Get to know your fellow interviewees before hand (they let you know who they'll be at the beginning of the day). The interview with Dean Brown was very pleasant. She was just making sure that your application is complete and asks some questions about your family.

Interview questions they asked
If you could travel anywhere in the world tomorrow, where would it be?
During the group interview we were each asked, 'If only one of you can get in this year, tell me why the person sitting next to you should be admitted.'
Read about NU's curriculum. Used SDN forums. Re-read my supplemental application.
What impressed you positively?
The students were far more laid back than I'd expected. I'd heard that Northwestern had some snotty students, but that didn't seem to be the case at all. It seemed like a diverse, well-rounded group who loved being at NU.
What impressed you negatively?
Actually nothing really. The dorms might be a little hard to live in because I'm an older student, but the rent around the school is sky-high. Dorms might be the best way to go for the first year.
What did you wish you had known ahead of time?
I had never been in temperatures that cold. If you are wearing a skirt to the interview, you might want to wear two pairs on nylons. The tour takes you outside a bunch of times.
