I just finished my Harvard interview today, and overall felt good about how it went except for one question that I just kind of froze on and wasn’t happy with my answer for. I of course immediately thought of a better answer to it after leaving the interview, and I’m just wondering if there’s any point in contacting my interviewer with that answer? She said I could email her at any time with questions, but I’m worried that it just makes me seem overly worried and not put together by emailing her an answer after the interview is long over.
As a Yale interviewer, I would find that odd (maybe a bit neurotic). If you think the interview went well overall, I’d leave it at that. When she said to email her with any questions, she was probably being polite more than anything else. If you have questions, it should be Harvard experience related.
@BKSquared That’s what I figured, thanks. If I think I made a factual error would you correct that? The question was about if I had any ideas for a film I would like to make (I’m a prospective film major), and I started talking about a Hitchcock movie called The Man Who Knew Too Much. The issue is that there are actually two different versions of the film and I forgot to mention which one specifically I was talking about, and then I also misstated one part of the plot. She made a note of writing down the name of the movie, so I just want to make sure she doesn’t look it up and think I’m lying about having seen it.
I was planning on writing a thank you note for the interview, would you think it would be worth it to add in a short note at the end of that saying something like “Also, so sorry but I realized I made two small factual errors earlier when discussing the Man Who Knew Too Much” and then elaborating from there? Or does that just raise more questions?
You’re way overthinking this. DO NOT add that bit to the thank you note but definitely write a thank you and get it out in the mail.
Thank you note is fine and appreciated. I wouldn’t bring attention to the small factual errors. I doubt she is going to research it. What I look for (and this interviewer probably as well), is how you think, how you connect dots, how you communicate your thoughts.
No, don’t contact her except to send a thank you note. You are human, and believe it or not that’s what they want to see.
She didn’t say to contact her with any answers 
There are times when you could mention something. I’m not even going to suggest when, because you’re so worried about this.
But generally, not to correct some error we’re telling you is minor. If she’s deeply into film, she would have asked you which version. Most of us don’t know that level of detail. Or care. I can’t imagine an interviewer commenting that you noted a film but not which version. Or got a piece of the plot wrong. Your admit chances do not hang on that.
@Eeyore123 Fair enough, lol.
Thanks to everyone for the replies and for both talking some sense into me and calming my nerves. 
Harvard interviewer here—as everyone has said, don’t mention it!
