I was a hobbyist programmer installing all sorts of Linux and BSD distros on my computers since the age of 10. My first real software job still had me go through a period where I had 50+ comments on some of my initial changes because life before work doesn't really prepare you for what you need to know on the job. If they aren't learning from your feedback and constantly making the same mistakes then I understand, but it's somewhat misguided to expect folks to simply know a lot early in their career.
Heck even folks coming in with experience, but from a company with a very different coding culture or simply a different primary language can result in the same situation.
Do you/they learn is the question. Not programming but a different role in tech but I’ve had a recent intern who did a very competent job and vacuumed up feedback and opportunities to learn. And I’ve had a longer tenure person who moved in from a different type of role at a different company who… did not. And just couldn’t appreciate how what they were creating was a net time sink for everyone else. They didn’t last.
