Since I already submitted my supp app, I can't see exactly what I wrote, but I believe I included a few words that brought out my humor, included things about the crazy humidity and temps and having to wear a suit. Looking back on it I probably should not have taken such an approach. If I had to do it over again I would include some things that I value like family/outdoor activities and relate it back to the school/South Florida area.
With that said, I did somehow manage to get an interview in September, and ill definitely ask what they thought of my answer and how they got to the decision to interview me.
Hope that helps a little and remember to just be yourself, in my experience people enjoy others that are genuine. Take a breath and jot down what you think is right.
Congrats on your interview in TN.
Cheers.
