I turned my application in early September. It took about 2 weeks to get contacted for an interview. You get an email link to select your time from 2 dates offered. i got offered my acceptance the Monday after my interview. In the future I think you will get called even sooner....but they weren't able to offer acceptances until the priority deadline was finished. They probably got a large amount of people turning their application in on the 14th so it might take them longer than 2 weeks to contact you for an interview. Good luck and hang in there!
I work PRN for an agency and have worked a few shifts at Northside. I wasn't impressed with the acuity or the facility. Have you considered Tampa General?
At the open house they mentioned starting interviews in September/October. Also, I'm not sure if they place a huge emphasis on the GRE. I know someone who was accepted for the previous class with a pretty low score. (she was strong in experience and shadowing) I think they look at you as a whole.
