When do you send thank you notes? Is it only for the interview or do you also send a note after a tour and information session?
We sent a thank you if we met with somebody personally. We didn’t send anything for group sessions.
It’s good form to send a thank you email to your interviewer and perhaps any professor or director of a program that you met.
And always send an email to your interviewer if you were accepted. The school generally notifys the interviewer if any of their interviewees are accepted, but another email is always appreciated.
