I'd say a mix of both, plus dentistry questions. The ones I found hardest were some hypothetical questions he threw at me which I think would have fallen in the "ethical questions" category -- like what would I do if this and that happened to me as a future dentist. He also asked me general questions about the field of dentistry, like what I know and things I've learned. What I did love though was that after each question he kind of used it as a teaching moment -- he would take what I said and then used it to add his own opinion and advice. So if that's any clue as to what UoP will be like, then I think it's going to be a great place to learn! Haha but like everyone else said, I think my experience is a lot less common. You'll probably just have a stress free conversation about you and why you chose dentistry 🙂
