It's not just school. There are a lot pieces of literature, tutorials/guides, discussions, papers I came across over the years that tell you something very useful _plus_ wrap everything either into OO (or sometimes FP) noise and treat this part as just as important. Often there are vague rationales sprinkled in without much backing. So you get interfaces that are much bigger than they need to be, visitor pattern this, manager that. As someone who isn't used to OO it is sometimes difficult or cumbersome to compile these kinds of examples and explanations into its essence. I also noticed that AI assistants often want to blow up every interface with a whole bunch of useless stuff like getter/setter style functions and the like. That's obviously not the fault of these assistants, but I think it's something to consider.
