<p>I can only tell you my own experience in high school, which was that my interviewers were never the same as the ones who interviewed other students at my high school, for Harvard as well as other colleges. I think it’s a simple matter of how they divided up the applicants, nothing to worry about.</p>
<p>Edit: Also, since there are several posters on this board who’re interviewers, hopefully one of them will jump in to give you a definite answer, or I guess you can just PM someone and ask :)</p>
