<p>Well I can tell you what doesn't work.
The representative from Tufts at one of the college fairs I went to was, for lack of a better word, a total snob. Complete with the nose in the air, and eye rolling anytime anyone asked a question. Talk about a turn off</p>
<p>So I guess what I'm trying to say is be friendly. I was extremely impressed with the reps that took the time to offer information, expanding on the very simple questions I asked. It only took them maybe 30 extra seconds. Also a friendly smile, rather than an "I don't want to be here but I have to look good" smile goes a long way. A handshake leaves a better impression too</p>
