The two last hire we got a year ago still don't have any ownership of anything. Even the project they coded 'themselve' where we involved them in the design and let them cook almost on their own, we are the one chasing bugs and defucking everything six months later because, probably unlike them, we actually read the PR (I'm mean, they probably did read it too, but today I'm extremely pissed, I'm at the point of calling a meeting to figure it out, it cannot continue like this). I've never took more than 4 months to at least understand most of the code, I feel like a year later their level of understanding is still the same. They are basically ai overseers at this point, but while I do more code review than ever before, I feel like they learn around the same as LLM, basically nothing.
