The question is actually "Have you come to terms with your own mortality?" not morality.
There have been a few on SDN that have gone through the phone interview this year. Do a search for "Mayo" under the Pre-Allopathic forms. It was a thread about a week or two ago. You will find many of the questions that were asked this year there. I do not know why that person has not put completed an SDN INTERVIEW FEEDBACK request as of yet, but hopefully she will soon.
Best wishes on the interview. Let me know if you have any questions about Mayo.
