What do you think??????

I applied to Albert Einstein Medical School last year late but was interviewed in late March. I was eventually rejected which literally broke my heart since it?s my first choice. This year while reading their brochure I notice that they discourage reapplying to their school unless the applicant has ?significant improvement?. I received an invitation for an interview last week; I would like to know your opinion on the following.

1) Is this a good sign since I was interview there last year?
2) Would I have been invited to another interview if I had received a poor evaluation from my first interview?
3) Will the admissions committee use both interviewers? evaluations when deciding my fate?
4) Is there a significant advantage at interviewing earlier than last year (my interview is in early Nov)?

Thank you for your two cents.
