Just curious questions：
For each EC, how many percentage applicants could receive a reply after sending thank-you email post interview ? I think even people said irrelevant, but seems EC only reply those who made good-to-great impression during an interview. My son had 3 interview for EA, the ones he got reply are those he felt good, not the one felt so-so or uncomfortable.
On the other hand, are most of those students finally admitted into MIT had a good/ great interview and at least received a reply after the thank-you-email-post-interview ?
If the applicant had a so-so interview (he interviewer ignore the thank-you-email), does this lower his chance to get into MIT? or just did not improved his chance to get into MIT？i think this depends how well in average those teens can handle the interview, for most of them, 1st formal interview in their life.
Most adults get nervous at job interviews, so it is fascinating for me to even think about how those 17, 18 years old to handle the interview. How many preparation is adequate for those teenages ? not seems careless and unprepared, also not seems overly-prepared or scripted answers？
