Just kidding. Don't piss off anybody. Your behavior is much more important than your knowledge. Don't interrupt anybody. Don't talk with your phone loud in the reading room. Don't jump into resident-attending discussion,
If thry tell youleave, for god sake leave. It means they are busy and behibd the list and want you to leave.
It is almost impossible to impress anybody by your knowledge, unless you are a radiologist. But try to behave so well that when there is ranking time, people say he was a great guy to get along with and we like to have him.
