I think its just about the applicant as a whole. Make sure that your essay really encompasses why you want to become an AA and what drives you. If you have one bad grade or a lower GRE score but make up for it the other areas, they are able to overlook that. They want to see diversity and well rounded applicants. It is not just about the grades or a test score.

This was just a phone call about 2019, not 2018. I was just trying to find out what a great applicant to them looks like.

The interview was a really fun process actually. The day before your interview you have a dinner meet-and-greet, where you get to meet some of the professors, interviewing staff, and students. That lasted about two hours and was really, really helpful. The next day you get interviews out of the way almost immediately. In my interview session, I had three separate interviews, one of which was with current students. In each interview you're asked about more or less who you are and what you're like. they can ask you anything from research experiences, about your personal essay, or fun things that you've done in extracurriculars. You might be asked why you're interested in Wisconsin, how you handle stressful situations, what you've done to help others ... But the thing I heard over and over again is that if you got an interview you are already qualified academically. Really they just want to get to know who you are as a person, and if you fit into the program.
