My fingers are crossed for everyone waiting to hear today.
I just finished my on campus interview this morning. It went well, and the questions were exactly as expected:
1. Visiting campus and impressions.
2. A time when you were working on a team with conflicts between team members.
3. A time when you were on a team without a clearly defined leader.
4. A time when you had to sell your opinions to people who disagreed with you.
5. 6-7 minutes to ask her questions.
No questions about my resume/background/why MBA/why Wharton.
My take on the behavioral interview format: it requires a high level of skill on the part of the person doing the interview. I felt lucky because the second year student who interviewed me was very personable. She put me at ease and did a good job keeping me on target time-wise. When I hadn't given her the exact information she wanted (what tactics did you use to achieve X?), she asked the question directly. I think I might have come away from the interview with a dramatically different impression if I had been assigned a less skilled interviewer who provided me with less structure (or didn't explain why he/she was writing the whole time instead of making eye contact).
This is probably a given for everyone, but bring a copy of your resume. I don't specifically remember seeing this anywhere, but fortunately I had brought a few copies just in case. I had the luxury of taking 2 days off of work, so I was able to tour the campus the day before and speak with current students. The extra day helped me get a better sense of the school and I was more relaxed for my interview as a result.
Anyway, since they only admit 40%-ish of interviewed applicants, I still have a very long way to go. But I'm glad this step is out of the way. If anyone has any specific logistical questions about getting to the interview location, etc. Feel free to PM me.
Good luck all!
