Yeah it's a little late but honestly it seems completely random as to who they decide to interview, regardless of when you turn in your app. Keep your fingers crossed.
What FSU honestly looks for: if you're from FL, if you are specifically from the Panhandle/North FL, if you're from a rural town, if you graduated from a FL school (+5 cool points if you did it at FSU), and if you legit want to pursue primary care (they are pretty good at picking through the people who just BS this on their app just to get in). Regardless, good luck. Let me know if you have school specific questions.
