<p>What do I do?</p>
<p>I know the basics, don't argue, be positive, ask intelligent questions, but I'm scared of what will happen when he asks the question I don't know the answer to. If I don't know the answer to a question (and this is bound to happen, one can't prepare for everything), what should I do?</p>
<p>It is not "bound to happen." The interviewer will be asking questions about you, presumably, and no one knows the answers better than you do. Just relax, limit the words "like" and "um," and--of course--be yourself. :)</p>
<p>As long as you've come across as a good, polite, smart, and interesting kid, then you've done fine.</p>
<p>If you don't know the answer to a question for some reason, just say so. There is nothing wrong with saying you aren't sure; it's usually better than just making up an answer. What kinds of questions do you think you would be unsure about?</p>
<p>You should say, "Can I come back to that question?" He will say "Sure" and you will move on. Be YOURSELF and STOP WORRYING. Know answers to the basic, obvious questions that will be asked: Why Harvard, what can you contribute to Harvard, why are you unique, why is Harvard a good match for you, tell me about yourself, what is you favorite EC and how have you contributed to it, what distinguishes you from the 20,000 other Harvard applicants, why should Harvard choose you. WARNING: DO NOT EVER EVER EVER EVER SAY YOU WANT TO GO TO HARVARD BECAUSE OF ITS PRESTIGE, even though that is true.</p>
<p>a lot depends on ur interviewer. Mine wanted to have an intellectual discussion with me about psychology, economics, and linguistics. needless to say it was fairly grueling in the sense that I could have easily sounded like an idiot, but it also gave me the opportunity to impress him because it was less conventional. I think it went well, but I guess you never know.</p>
