My Harvard interview (in the dark ages) was horrible. It was in the apartment of a local alum, who had no furniture [yet?], shaggy carpet, and multiple pets. I was wearing thin tights and a pencil skirt, and am very allergic to animals. I was very squirmy. Additionally, she had been a cheerleader and that’s all she wanted to talk about. I did not get into Harvard.
I loved my Princeton interview - in the guy’s office, and we talked about all kinds of things. I did get into Princeton.
Of course, I doubt it was only the interview, but…
