You can apply to more than one. Just make sure you write specific personal statements for each specialty. Have your LOR's be specialty specific too. It is always great in a letter if they can say why you will be such a great ER doc, anesthesiologist, or you get the point...
When you interview they are going to ask you why you want to be a (fill in the blank). I just don't feel that it comes across good to say you would be happy in their specialty, or another, or this other one. So when you answer this question, act like that specialty is the only one in the world you could even consider.
One of my very first interviews, one of the docs asked if I had a back up plan or if there is anything else I could do... Unfortunately I was honest and said I had some back up plans in another specialty.. Her reply - I guess you don't really know where you want to end up then do you? This program has made their contacts to the people they wanted to take, needless to say I wasn't one of them.
The correct answer would have been - if I don't match then I will scramble into an internship and reapply next year.
