Interview Tips

I have my MIT interview tomorrow, and I would love some tips on how to prepare.
I’m nervous but also excited. What are some questions I should ask the interviewer? What questions should I definitely be prepared to answer?
I’m afraid of being asked, “what’s your biggest accomplishment?” One of my friends was asked this during his Navy Interview and was stumbled. Honestly, I’m 17… I don’t have some ‘great’ accomplishment.
What was your interview like? Was it fun? What if I don’t connect with the interviewer? Any tips will be appreciated.

Thanks!!

There are a large number of interview prep threads on this forum, and you can search for some specific advice, but from my perspective, as an interviewer, I find that most people are not comfortable or used to talking about themselves. And this can be practiced. Get friends or family to quiz you about YOU. It can be anything. What is your favorite book? Movie? Dinner option? Which celebrity do you think is massively overrated and why? What class do you dread at school, and which is your favorite? If you are stuck on a desert island with only 5 albums (and a way to play them), which would you want to be stuck with?

Now almost none of these questions will come up at an actual interview, but the idea of thinking about yourself, what you like and dislike and why, will help you prepare for the questions that do actually come up.
