<p>I made a MIT account and have been assigned an interviewer. Am I supposed to initiate contact with this person? Or does this person contact me?</p>
<p>You’ve got the choice, so it’s you who has to contact this person [usually known as an EC or educational counselor.] Sending an e-mail is fine, asking to set up an interview, and note that the subject field should probably read “MIT Interview” or similar.
There are also deadlines that you have to contact your EC before, or you lose the opportunity to set up an interview.</p>
