IUSO Admissions Day

Does anyone who applies to Indiana University Optometry School get invited to an Admissions Day interview? Or do they first narrow it down then invite people to an interview?

I'm just trying to figure out if I should feel special because I got invited to the IUSO Admissions Day, or does everyone get invited! Also, how do I make myself stand out during this process to guarantee a spot in their program?

Thanks,
