Besides spending the day in the morgue the morning after you watch a horror movie, we hope nothing at works makes you too uncomfortable. This question can also be considered a 'weakness' question. Tell the interviewer if working in large groups makes you uncomfortable, public speaking or performing examinations on children. Whatever your discomfort be sure to tell the interviewer that you are working on making the issue more manageable.

"Speaking in public in front of large crowds makes me uncomfortable. For whatever reason, I seem to freeze up despite the hours of work I've put into my speech. I've been working on presenting my findings to groups of 5 or more to help me with my fear. So far so good, my intentions are to work up to groups of 10 next week."
