This is simply not true. Stop trying to psych him, Lloyd.

Hayward makes some good points. Mostly just be yourself. The whole process is really about your ability to balance being human with some elements of pressure (think: grace under pressure), ability to make decisions using some demonstrable intellect. Be prepared to answer questions about your views on the role of the physician in society and how this has changed over the past 50 years and where you think its going. If the interview is soon, suggest you get current on the WHO and the avian flu. Try reading the economist for some mature views on the world political situation. Be familiar w/what is current in basic science (read Science/Nature/New Scientist). Having some interests outside of science & medicine will demonstrate you won't immediately burn out. Bring such an item or photograph along for interest (e.g. artifact from your time in wherever it was you grew up). In the group interaction interview, don't be afraid to be a leader, but avoid being pushy. There is quite a bit of teamwork in medicine. Hope this helps.

Note to add: one thing to remember in these interviews is that you want to stand out, but not as a smart-ass. Remember the ppl interviewing you are (mostly) physicians. I am assuming you are quite bright so I will share some advice about the "interview game": NEVER give an answer that is smarter than the person asking the question. Remember that those ppl interviewing you are ppl who take pride in their intellect, so you don't want to come across as offending that in any way. Be bright, be sincere, be human, and be humble. Show off your POTENTIAL, not your superiority or you run the risk of offending some members of your committee.
