Hi!
Yeah it was me with another applicant and two professors who interviewed us.
It was pretty laid back and they try to make you feel comfortable. They mostly want to get a feel for who you are and if you'll be a good fit for the program.
Your process might be a little different I've heard other people had a bunch of ice breakers too. But just be yourself and just prepare for the typical questions like why do you want to be a PT and why APU.
Good luckk! I might be at preview day too that day of your interview
