Before your interview, be honest with yourself and consider any shortcomings you may have coming into a surgical critical care fellowship. As long as you have a plan to address it, your interviewers will respect your answer. Also, rather than focusing on a potential deficit in your ability to perform as a surgical critical care fellow, pick a common weakness or discuss a common misconception about training in the subspecialty. Then, explain how you have taken or will take steps to prepare for this hurdle. Conversely, if you don't have any worries, confidently express this to your interviewers.
