I have been to a ton of info sessions and personally I can tell you that those are not really the forums where you try to somehow gain the confidence of an admissions director or anyone else responsible for admitting students. They are all there to sell you their school, not to scout out the best b-school recruits. I mean the admissions committee holds hundreds of these info sessions in several different countries..so don't feel bad if you got the feeling that you didn't leave an impression because I'm not sure that during those sessions they ever really give you a chance. It seems to me the only way to leave a strong impression on the adcom guys is to have a great GMAT score, great grades, phenomenal work experience and extremely interesting volunteer experience...but I could be wrong
