I'm a current student and for the interview, the biggest thing is to really show your drive to become an AA along with understanding the AA profession. If you get invited to an interview, you have what it takes academically to complete the program.

At the interview, ADCOMs want to see that you work well under pressure, have good communication skills, and can think on your feet. They also like to see your personality to ensure you will fit well with other classmates. My stats were a tad higher than yours (3.52 GPA) and I had some HCE as well. As long as you have a good MCAT/GRE score, I would think you'd get an interview.

Good luck, hope that helps!
