unfortunately it can mean over-confident, though (or simply not understanding how clueless you are?)... we had a nice guy at work - young, friendly, ambitious. got some weird vibes a couple of times when i tried to help him out with problems, but thought little of it. then he leaves and i have to maintain his code. why the fuck didn't he ask for help?

and yes, this implies something about the company culture needs to be fixed. the blame certainly isn't all his.
