I can't speak for everyone's group, but my interviewers didn't ask anything about my GPA. They did, however, close the interview with the question, "Do you have anything you want to tell me: bad semesters, life stuff, etc." and I told them about a bad semester I had. The admissions committee has your GPA and PCAT on file, and I think because I completed my Academic Update so early that was part of the decision to accept me so quickly. I was very surprised, because I thought I botched the interview (I'm very hard on myself 😛 ). But, yeah, they could ask you a question like that and then you can describe a bad semester or normal GPA, etc.
