I'll answer these questions for me specifically -- not presuming to be able to answer for other ESTx's.
what do you guys do on your spare time?
I spend a LOT of time with my friends. We have movie nights, dinner parties, we go out searching for new restaurants, we walk around the city, we mix drinks and watch YouTube videos... anything, really, as long as we're shooting the shit and having fun. (My love language is Quality Time, so it hardly matters what I do with my friends as long as we're all together.)
Unrelated to friends, food, travel, or exploring, I like to make things. Music, cooking, DIY, whatever -- as long as it's a creative outlet and involves the satisfaction you get from delivering an excellent final product.
What do you dispise about the world?
Hypocrisy and ignorance. Especially hypocrisy. We've never been able to come up with a set of rules that we could stick to without weaseling our way out of some of them, for "special cases".
WHat do you guy major or in or plan to major in?
World History -- focused on theology, political science, and the modern history of Arab-European relations.
Which personality types do you find the most difficult to deal with?
I don't think I have an answer to that. It depends too much on other factors.
How would you feel or act if things weren't "normal" or "in control"?
Depends on the type of "not normal" or "not in control" you're talking about. What scenario do you have in mind?
