Hey there!
I was an applicant last year so maybe I can give you some insight into what interview day/the interview session is like. Brenau was definitely the most relaxing interview that I had (I applied only to the Georgia schools). As with most interviews, there's usually a introduction of the faculty and from what I remember, there's a group interview (although it ended up being more like a Q & A session) as well as a personal interview and tour. The personal interview for me was very casual and flowed a lot like a conversation. Question-wise, there wasn't too many but the questions seemed to be geared towards your character and how you got to wanting to become a PT. From what I remember, the turn around time for decisions was pretty quick.
As for interview advice, definitely look up the school/program and see what it has to offer you (e.g., early immersion) that other schools might not offer. Read over your essays and give yourself a refresher of what you wrote about, but other than that it's a bit of luck who you interview with and how at ease you feel when you're interview. Hopefully this helps, and good luck!
