<p>As an alumni interviewer for Duke, I personally wouldn't ask any of those questions. It's common (and good) sense that you are going to be applying to several schools, and we may or may not be your top choice. I wouldn't want to put an applicant in such an awkward position, and honestly, neither does Duke -- which is why we are specifically asked to avoid questions such as the ones you mention. The only exception I would make to that rule is for applicants who are applying Early. In that case, I would expect that Duke is your first choice, and I'd want to know how you came to that decision.</p>
<p>That being said, alumni interviewers are given fairly free reign, and it's really up to the alumnus to decide what to ask/not ask. If you do end up with one of your "painful interview questions," I'd say be honest. Don't lie. If it's one of a few top choices, let the interviewer know that and try to steer the question toward how you came to put it in your top bunch. Ask the interviewer if he/she has any advice on making the decision. Keep in mind, we aren't just there to evaluate you -- we are trying to make you <em>want</em> to attend our school. Most interviewers aren't trying to ask "gotcha" questions; they want you to succeed. </p>
<p>Also remember that for most schools, the interview is just a small part of the overall picture. It can make a difference, especially for those who are hovering on the border, but it will rarely make or break you. It's the "nudge" that can determine which pile your file goes into.</p>
