Congrats on your interview! What day is yours? I have mine on Monday. I've heard from another applicant who interviewed a week ago that there were two essays. Personally (correct me if I'm wrong Dr. Chuck), I think these are to test our ability to write a coherent essay. Mainly to inform the school whether or not we wrote our own personal statement. The individual who told me about the essays said that one of them asked the interviewees how they would redecorate the waiting room.
