Why can't it sound good to say you won't miss patient contact? I don't... I never will and I knew I wouldn't once I did my medicine and family practice rotations.
And what's with all the questions about how to answer such and such question? It's fine to not actually know the answer and maybe get information to strengthen your own opinions but the only correct answer to any question is the truth as you see it. If you get into a program because you answered questions in a practiced way that didn't reflect your actual opinions and beliefs about your expectations chances are you're going to be in a bad program for you.
Why would it sound bad?
Two people answer that question.
1- No I won't, I knew that medicine and family practice weren't for me. I want to do pathology.
2- I might, but I found that areas of medicine that interest me are the diagnosis and disease process. Pathology seems like a good fit.
The interviewer might take 1 as someone who is running away from the rest of medicine, and not to pathology in particular. 2 is more suggestive of an interest in pathology.
Yes staff pathologist will say things "I knew I didn't want to be around patients...", but answering questions in an interview is an attempt to put your best foot forward. We are responding to possible candidates, not current residents.
Look, if you do your interviews and don't try to answer things in a positive fashion, just whatever you feel like, and you get jobs, more power to you. Ignore this advice, it is for people who are worried about saying the wrong thing or coming across in a bad light...
Oh and we aren't saying lie. If you are going to really miss patient contact, pathology is not a great fit, people do leave the field and sometimes it is for that reason.
