You may want to take a gander at what SDN has regarding frequently asked interview questions by school (based on feedback from interviewed applicants). Here is the link http://studentdoctor.net/schools/?view=dental
Practice a variety of questions with friends and family. Maybe your undergraduate institution has a Pre-Health office- they may conduct mock interviews so check that out. Lastly, you want to be structured, but not too structured. More specifically, you want to have an idea of what you want to say during the interview, without your answers coming off as "canned" if that makes sense. You'll still have a couple of months to fret over this 😴
do a little research on the school. Trust me when the kids who are giving tours here the same question...90 different times. It makes their heads rattle, and please be personable. Treat your fellow interviewees with respect. Past that just be yourself.
Sorry, you don't get to see my responses, come up with your own 😉
Most of the last few questions are just pretty typical ones... aside from that just look at the interview feedback and try answering some for practice. Also when you're making this, don't use complete sentences. That way when you go on different interviews, it'll be different every time and won't sound rehearsed.
