<p>i had an interview at carleton a few days ago, but i lost the card the student interviewer gave me admist all the other brochures and stuff. this worries me because it looks rude if you don't send a thank-you email, right? just wondering how big a deal that is...</p>
<p>Just call the admissions office and ask for the name of your interviewer. It's always nice to follow up with a thank you and any additional questions/observations you have.</p>
