Re-Interview Advice

I was wait-listed at a program last spring and never got off the list. I'm interviewing at the same school next month and was wondering if anyone has advice on what the interview may be like this time. I know they'll probably ask me what I've been doing with my life over the past year/what makes me a stronger applicant but that's all I can think of.

Has anyone been in this same situation or have any advice to offer?

Thanks!
