Two things: Anyone out there that had a kid that interviewed for college via zoom? How did that go?

Also, with increasing applications, like Harvard ED almost doubled, how do they get the all the interviews done? Do they more, inexperienced, or are interviewers overwhelmed?

My older two did Zoom interviews last year, prior to the pandemic, though this was for grad and law school.

I wouldn't worry about it. I don't even know why they do interviews. Read up on interviews for elite schools on College Confidential. I don't think they figure into admissions (unless perhaps you are really rude, resulting in a sure rejection).
