Should I follow-up about poorly answered questions in an interview? I had an interview today (my first one) for a teaching stream position at a college, and I'm unhappy with a couple of my answers.

Should I just consider the matter closed and send a follow-up email to the committee thanking them for their time? or is it appropriate to include a few remarks and/or clarifications about the questions that I wish I answered differently?

Appreciating any advice.  Thanks!
My advice is to take a deep breath, what happened in the interview room is now a closed book. While I am sure that we would all like to sometimes be able to change the past. The past is a sealed land.

I suspect that as it was your first interview that you messed up royally in some way, do not be disheartened. Learn from what happened, chalk it up as experience.

I am an associate prof, I went through a lot of attempts to get my first academic post. Each time I failed in an interview room I failed less bad than the last time. I would use your interview failure as a chance to try to identify any training needs you have.

If you act in a sensible way on these then you can make yourself into a better academic.
