Expect to write an essay in about 15ish min on a picture related to PT. and interview with faculty member. Interview questions are pretty similar to a job interview, ethical, strength, weakness, long term short term goals etc.
Refer to megi1212's post. He/she listed everything you need to know to help you prep for the interview.
In addition, I would like to point out that the interview is not your typical interview. You are given the opportunity to best display your personality/character to all the faculty members. Wish you the best of luck 🙂
There were about 25 people. We were there from 7.45 and I left around 1.30pm! People who went on a tour stayed even longer. So it was longer than 2-4 hours as they said it would be. Good luck!
