The Temple interview was pretty relaxed - but not too much so. They broke us into smaller groups to do the interview. In my group Dr. Carp and two students took turns asking candidates different questions. They were pretty much "text book" interview questions but some were a little tough to answer on the spot. I would come up with a few examples that you could use when asked to show how you handle difficult situations, embody different traits and skills, etc.
They say that the interview counts for only 5% of the decision and that if you are offered an interview you have made it passed the other 95% of the process. I think they said something like a 90% chance of acceptance. I do know someone who was not accepted following an interview this Fall but I don't know the details.
Good Luck and let me know how it goes!
