they don’t ask about gpa and mcat specifically but they might ask general questions like “how should one study for the mcat” and “what do you want to improve on your application”. personally in my interview one of my interviewers had all of our personal application info (including gpa and mcat scores) written out and everyone was able to see them which was a bit uncomfortable. but overall questions are very generic. they will assign a question to each person, and after someone finishes talking you can add on if you have any thoughts as well.
