<p>I don’t think it would hurt to send another e-mail. It would be especially nice if you can mention something you learned in the interview that further solidified your interest in the job or if something came up in the interview that specifically relates to your qualifications, and you’d like to make sure that they know that you’re a good match for the job in that respect.</p>
<p>I would send another thank you. It can never hurt. I always send thank yous after every interview, if there is time, and I am sincerely interested in the position.</p>
<p>D sends an email after every interview and a written letter after that --for every interview. Just a note card that says something a bit more than the email. She sends both to every person she has had contact with at that school or business.</p>
