Do not under any circumstance lie to a program director. It is a small world-program directors often discuss residency candidates. If they catch you lying it is likely they will not rank you. Without question, lying to a program director will result in burning bridges-you never know where you may want to consider a fellowship or faculty position in the future. Be attentive on interview day and arrive on time.
Programs frequently begin the day with an orientation session led by the program director.
Don't appear disinterested or sleepy. Be gracious, friendly and polite to everyone during the entire process. Remember that the Department Chair's wife may be working in the gift shop. You never know who is connected to whom. And secretaries frequently report rude behavior to the program director.
