I actually loved my temple interview. I am from Idaho (haha so it was a long ways), but it definitely made it as one of my best trips. The school is in a pretty scary part of town. I was only there during the day, but I never felt threatened by anyone or anything while I walked around.
The interview day started with the group of us meeting upstairs. We just sat and talked for awhile, getting to know everyone. We then watched a powerpoint about the school and got information to help us with housing and everything. The admissions people were VERY friendly and along with the interviewing group, it just felt like I was hanging out with good friends all day. We had lunch with some dental students and were able to ask them any questions we had.
I know that some people have a problem with the interview being a 3-5 min video, but really I felt like I got to say everything I needed in about 3. They have your application, they have your stats, and they spend the whole day getting to know what type of person you are. It is a very enjoyable interview. If you have an invite there, you should look forward to it and enjoy the experience.
