Hello!
I haven’t been contacted yet for an interview, but my friend said she received the interview in her mom’s email box not her own email. It sounds so weird that harvard doesn’t contact you directly. My mom just totally forgot her password, so I am nervous that my interview invitation may lie in my mom’s email box. I just want to make sure that are there anyone receive their interview invitations in your parents’ email?
How the interviewer contacts you depends entirely on the interviewer; some will email, while others will call.
But if they email you, they will email you , not you parent(s) at the address they have. You can check your spam folder.
Note that just because your neighbor/friend/classmate got an interview request does not mean that you will have the same interviewer, or any interviewer. It’s supply/demand with a hint of randomness.
