Congratulations on getting the interview. I can't really say whether Dec is bad or not, but at least it isn't Feb or something. I interviewed on Oct 4th and thought I was pretty lucky to get that. The whole interview day was pretty cool. I admit I was high strung on the inside for most of it. The interviews themselves were surprisingly relaxing. I didn't get any "dead baby" ethical questions. The first interviewer had me elaborate on parts of my essay and then asked about my family. The second interviewer and I mostly told sea stories and laughed.
My physical consisted of the normal head to toe checkup followed by a rousing bout of turn your head and cough. There was an eye exam, a urine test, and a hearing test too. The physical instructions state that a visual rectal check is MANDATORY. The doctor didn't do one on me. Now I looked on the website they gave me to check my medical status and it says I am "remedial" until I go back for that loving rectal check. So if your doctor tries to defer the rectal exam.......tell him to head south or you'll be back later. Oh, and I had lasik eye surgery so they need the actual surgical records. Otherwise I think that's all they cared about.
Good luck on your interview!
