<p>for the interview, should you restate your main ECs or should you show a different side of you so that the school can get to know you even better (would this be misunderstood as "dispassionate about main ECs"?)</p>
<p>You can certainly talk about what EC’s you do in the interview if that’s something you want to talk about during the interview (as a topic of conversation), but it doesn’t make sense to go on talking about what’s in your application. What would be the point of that? To bore the interviewer? </p>
<p>Your second question suggests that you have to be passionate about your EC’s, and that you’re not passionate about anything else. I did volunteer work in high school, but I wouldn’t say that I was passionate about it. I was certainly interested in it, but not passionate, and that’s perfectly fine. The point of the interview is to have a conversation so that the interviewer can get to know you a little better, not to rehash your application. It’s not necessary to show a different side of you than what’s on your application either. The interview is pretty much a low-key way so that the interviewer can get to talk to you in person.</p>
