I have already been invited to three different interviews. My cum. and sci. gpa is a 3.6 and my DAT AA is an 18. I am assuming that part of my reason for getting invited is based on my extensive research experience (graduated over one year ago and am currently a medical researcher) and the fact that I worked over 30 hours a week while going to college. Also, how big of a deal is it to get invited for an interview? This is my first time to apply, so I am somewhat new to all of this.
