I got THE CALL from Katie Horne almost exactly one month ago...funny thing is, I was waiting for my mom to call me back and I assumed it was her when I picked up my phone. I almost answered, "Yeah", but something stopped me and it's a good thing. When Katie Horne introduced herself, my heart stopped. I was driving and had to pull over. After I got my offer, I just cried (I'm a sap about this kind of stuff).
I hope other people have been able to share my good fortune; I know what it's like to sweat bullets. It's also good to know that other people have contacted Katie on several occasions...I had started to feel like I must have been annoying her.
If I could give any advice (I realize it's getting late), I'd say be creative with what you send to pad your file. I sent a copy of an award I'd just gotten from school, etc. I was told at my interview that "letters of recommendation carry a lot of weight here". I think it's not important WHO the letters are from, but how well the people know you. For example, I had a local doc who is a Michigan alum offer to write a letter for me, but I said no thanks because he didn't really know me very well. Instead, I sent letters from parents of my violin students, etc., because these people could write colorful letters that really painted a good picture of who I am.
Best of luck to all of you!
