I remember a while back I was looking at a college that had a bunch (probably between 7 and 12) houses. They were like Hogwarts houses almost. You would rank them by your interest and they would choose among the incoming freshmen. Each house had it’s own personality and would host like a weekly dinner. I think one had a fued with mit? I thought it was Stanford but its not. Pretty sure the university has no Greek life and it might’ve been on the west coast. It wasn’t Notre Dame either, though I understand their system is similar.
