The interviewer asks this question for several reasons. They want to see what draws you to their program and that you have done your homework on their school before applying. If you have done your research, you will see that the Indiana University School of Medicine is a national leader in medical research and education, and they have more than 60 academic departments and specialty divisions across their nine campuses throughout Indiana. Perhaps what interested you about their program is the faculty-student ratio of 2.1:1, the medical curriculum, or the four-year program specific to rural medicine training. Or, their program may be interesting to you because of the summer research opportunities with hands-on training through projects in Indiana and abroad. Let the interviewer know that you have performed your research and what interests you most about their program.
