Word of advice: I would suggest not using the word "osteopathy" in your interview. It's a bit outdated and I got yelled at by the Dean last week for using it 🙂 Osteopathic medicine or osteopathic physician is preferred. All diplomas now say "Doctor of Osteopathic Medicine" and the ones that dont from years ago are being reissued.
Dont sweat the goose poop. The geese have actually been displaced (for good I hope) by a major landscaping project that's underway.
The interviews are usually pretty relaxed. Practice writing what you want to say on your secondary (why nycom, why osteopathic medicine, etc).
good luck.
