<p>As is the case with all thank-you notes, you should not send a preprinted card, but should write a note expressing appreciation for the person's taking the time to interview you. You also should mention anything that you particularly appreciated or learned.</p>
<p>I had a great interview and my interviewer was a really nice person, but I only have her email address. Is it okay if I email her a note or send her an online card? I would send it sometime soon, but I don't want her to think I'm brown nosing...</p>
<p>Don't send her an on-line card. That is tacky.
It is polite, not brown nosing, to send some kind of a written thank-you. If all that you have is her e-mail address, then send it to that address. Sending thank-you notes after interviews is considered courtesy.</p>
<p>Unfortunately,most applicants are not courteous. My experience has been that the applicants who eventually get accepted are more likely than others to have sent thank-you notes. I think that their acceptances reflects the appreciative and kind way they've treated people throughout their lives.</p>
<p>For instance, one accepted applicant who had sent me a thank-you shortly after his interview also took the time after acceptance to set up (at no charge) the computer of an elderly alum who had attended a dinner party that we threw for accepted students. She didn't ask him to do this nor was she a prominent or wealthy alum. He heard she was having trouble with the computer, and then he volunteered to help her.</p>
