I had my interview in October. The professor I met with didn't ask all the "normal" questions one might expect (e.g. "Why dentistry", "Why LLUSD", etc.) It was more of a conversation about who I was as an individual.
My spirituality was also "dissected", along with my personal life-story.
I have two friends who interviewed in October also. One had a similar conversation-type interview. The other one got asked all the normal questions as previously mentioned above.
I would recommend knowing what you might say if asked the "normal" questions, but also have an idea of who you really are. Stress your community service/volunteer work. My interviewer stated that he can "see through BS", which was pretty intimidating. Don't force anything, but verbally illustrate to them how you're different than other applicants. 👍
