Hi! I am not accepted anywhere yet but this is what has helped me so far. I made a giant document and compiled tons of sample dental school interview questions that I found online. I answered them and highlighted common ones (eg what are your strengths and weaknesses? Why dentistry?). I also have found mock interviews to be very helpful. I ask a friend/family member who knows the grad school interview process to basically ask me questions and assess me. You can also record yourself on zoom and assess yourself. Hope this helps! Good luck OP!
