<p>If they don’t consider any application without interview, why is there that 3% acceptance rate? 
This may help:
[MIT</a> Admissions | Blog Entry: “It’s a puzzlement…”](<a href=“http://www.mitadmissions.org/topics/apply/the_selection_process_application_reading_committee_and_decisions/its_a_puzzlement_1.shtml]MIT”>http://www.mitadmissions.org/topics/apply/the_selection_process_application_reading_committee_and_decisions/its_a_puzzlement_1.shtml)
Missing the interview means missing a chance to tell them more about you. If your application is just perfect thought it’s without the interview, they still want to have you. However, who knows how good is perfect to them?
Even so, trying to have an interview does show your interest. You know, MIT’s intellectual environment is pretty tough, so if you don’t have any interest in MIT, that may mean you’re not ready to take the challenges, especially in the case that this aspect is not shown clearly in the application.</p>
