I personally had a really nice interviewer. It was not anything too intense and I don't remember being caught off guard with any questions. I remember why PT, why Drexel, I think they asked me about an impactful experience I had or something about is there anything I'm passionate about or something along those lines involving my community service experience. Make sure you have questions for them as well, it looks bad to not have any questions prepared. It was so long ago so its hard to remember but I didn't feel like there was anything crazy being asked as long as you know the basic questions.
