Hi nfefe
I worked as a curatorial intern at the new museum for a semester. My advice: don't uproot your life for this internship. It is unpaid (you aren't treated the same as the paid employees there), it is not in a very "hands-on" environment (no permanent collection, the curators will have you do research but won't include you in discussions, meetings, etc.), and you will be given smaller, sometimes menial tasks unless you have extensive experience already in some sort of curatorial or contemporary art field-- in which case you probably shouldn't be taking an unpaid position. While it was eye-opening to see all the work that goes into museum exhibitions, I felt like I was not a super valuable member of the team. All of that being said, I'm totally glad I did it! But I also lived in New York already and have a paying part-time job here. Unless you're lucky enough to not have to worry about finances, I'd say you should decline. Hope this is helpful? Feel free to message me privately!
(EDIT: wrote assistant instead of intern at first-- to clarify I was an unpaid intern, the assistants are paid)
