Absolutely! I interviewed on 9/10 and was accepted and I will be attending there come May! If you look back on this forum, there's a post from two current students of the program regarding the interview format and they were right on point with how mine was.
They'll have everyone interviewing that day come to the school around 9:30 (or whatever your email says) and the dean will give you an overview of the program and a tour of the PA building and answer any questions you have as well as tell you how the interview is going to go.
Then they'll bring in some current first year students to answer your questions and the dean will leave the room. They will start coming in to pull you one-by-one for your interview according to the time your email said your actual interview will occur. Ask the students anything you want because anything goes! They're very helpful and will answer any question you may have. After your interview, you can come back to the room and talk to the other applicants and current students some more if you like or you can leave if needed. You have no further obligations after your interview is completed.
If you've never been to AB, I encourage you to take 5-10 minutes to walk around the campus so you can get a feel for the atmosphere. It's somewhat quaint and small. I live about 30 minutes from the campus and I take prereqs there now. I really like the small campus and the atmosphere. Everyone is seriously so nice and everyone seems to know everyone.
As for the actual interview format, you will be interviewed alone by 2 faculty members. Mine was a PA and an admin assistant (not a PA). It's very traditional and will only last 10-20 minutes. They'll ask you the basic questions like "why do you want to be a PA?" and "What area of medicine are you interested working in as a PA?" and some just personal get to know you questions. I've heard some people say they will ask you "If you could be anything besides a PA, what would you be?" I did not personally get asked that question though. Overall, it's very lax and probably the easiest and most laid back interview you will have. Don't be nervous! They're all very nice and just want to get to know you! You'll realize that as soon as you step in the door!
If you have any other questions, please let me know! Good luck!
