analyst class social dynamics

I’m in FT training rn at a BB and been feeling pretty out of the loop. It seems like most people kinda stick with their friends from their internship groups and there isn’t a whole lot of camaraderie on a class level. I interned at a different bank in a non-NY city and am the only one in the analyst class of ~250 from my nontarget, so it feels like being the new kid who transfers high schools junior year or something. Ik i probably won’t hang with most of these kids outside of work anyway and have a healthy social life with non-bankers but damn it feels like ppl just are way more closed off than the intern days. Wanted to see if this is the universal experience or if my BB is just so particularly cliquey? Or maybe It’s a full time hire thing? Other an1s or older guys feel free to chime in
