When I interviewed applicants as a chief, I did the following:
- review their numbers and verify that things seemed "normal" for the group that had been selected for interviews. If there was a glaring discrepancy, such as an unusually low board score, I would make a note of that and ask the faculty about it later.
- focused on all awards, activities, etc. listed on the application. I figured if they listed it, they want to talk about it - IN DETAIL. If someone put down something strange or unique, I found that either they were really passionate about it or shouldn't have put it on there. One guy didn't know the meaning of a word contained in the name of an award he received.
- if someone wasn't easy to talk to and I was out of ideas, instead of asking the mundane "desert island" questions, I asked them to agree or disagree with a statement like, "health care is a right". Not to see whether they agreed with me, but just to get inside their mind to see how they reasoned.
- be passionate about something - the more unique, the better! I talked with one guy for the whole 20 minutes about his online course/degree/certification in refrigerator maintenance.
