"How are reapplicants viewed?" "How about those who were interviewed?"
If you interviewed at this school this cycle, initiate a conversation about how you were impressed with the school and mention a few particular things that really stood out to you about the school and that you genuinely believe that you'd be a good fit there. Be modest and genuine when you ask something along the lines of - "I understand that I was rejected, but I'd like to learn why I was rejected post-interview."
The admissions person may ask you what you're doing to improve your application. You can consider taking a few upper division bio classes this summer or say you're continuing to shadow. Basically you don't want to seem like you're just waiting around for the next cycle to roll in and reapply as the same applicant again. Show that you've matured through this cycle.
