Should I send a thank you note after an interview?

I am reposting this question because it comes up from time to time. If you have a different opinion than mine, please let me know.

Question: Should I send a thank you letter following a pharmacy school interview?

Answer: Some years ago, I received a thank you note or email from what seemed like most of the applicants that I personally interviewed. Today, however, I receive very few.

What I will point out though, is that I tend to remember those applicants who did send the note (which is the point of sending the note, right?). On several occasions when discussing a file, I have heard a commitee member comment that they received a nice card or email from the applicant being discussed. While it might not sway anyone's opinion, for the time it took to send the note, I'd say it was worth it.

I might also add that if you have been working with someone in the admissions office closely, it would be very polite to send them a thank you email as well following an interview. Sometimes I think they get overlooked
