This interview is very laid back. They want to get to know you on a personal level so just be yourself. With my interview it was just a faculty member and myself. As for the rest of the day, you meet some of the other faculty, tour the campus, lunch was provided and They have an info session about the program and financial aid. My best advice is just be yourself and show that you want to be a pt and that you are passionate about it! They are very personal hence why I chose une over other programs. I hope this helps. Good luck.
Oh and if you have time there are tons of great restaurants in Portland. Portland lobster company, Gilbert’s chowder house to name a few.
