<p>I would ask how they liked their experience at Cornell and whether they would choose it again. What did they like the most, what did they like the least?</p>
<p>As someone else said, I would avoid asking basic questions like how many colleges there are or other question that you could learn the answer to on the website. </p>
<p>I would also take the opportunity to convey any information that you think may not have come through completely or clearly on the application. For some students this is not an issue, but it may be for some. It also does not hurt to demonstrate some level of knowledge of Cornell. Polishing up a stong response to “Why Cornell?” can’t hurt.</p>
