Hey! So you'll arrive to the SoD and meet on the administrative floor (3rd floor I think?) with the other interviewees for that day. You'll all be sitting in the conference room making small-talk until the interviews begin. It'll be one-on-one, so you'll leave the room and return when you're finished.
Afterwards, you'll take a tour around the school, really casual. You'll get to shadow a few students in the clinics, followed by a pretty good lunch. While eating, you'll get to sit down with some dental students and ask any question on your mind.
After lunch, you'll go one-by-one to record a 1 minute video about yourself. When everyone has returned, you'll participate in a short writing exercise. It's just a bunch of different scenarios asking for what you would do, or what you think the right answer is. It's all open-ended though, so don't stress about it. After that, the day was pretty much over.
