Current USC dental student here - I'm involved with helping out with the admissions process. Just wanted to address some FAQs I've been seeing:
1. This year, the Kira assessment is part of the initial application to qualify a candidate for an in-person interview invite. This means that everyone who applies is asked for a Kira submission. The in-person interview invites are extended only to a select group of applicants.
2. The in-person interview will be your PBL interview. You'll then sit through a number of presentations about the school, financial aid, etc., followed by lunch with student ambassadors, then a tour of the dental school. You'll probably be tired after finishing the interviews, but do your best to stay engaged during the lunch and tour - the admissions office asked us to report back the names of applicants who stood out (both in a positive and negative way).
3. Interviews are held on Mondays, Wednesdays, and Thursdays.
