going by the UPENN threads in SDN...those who have been there say that there is nothing to prepare....u just have to be mentally strong and confident.....just be yourself....don try to be or portray what you are not....read ur sop carefully....rehearse answers to possible questions....
i don think there are any clinical questions that are being asked.....it is a very relaxed atmosphere and they really make sure that you are taken care of nicely......
but i can give you a suggestion which you or others might think that it is not apt among all this interview frenzy that we are in....but i believe it really helps calm ur mind and soul......try meditating 15 min everyday.....someone gave me this advice and it is helping me.....it might work for you too....
