Also, not implying this is the case but often I see junior developers saying they've done X but have to double check if they overlooked something or mangled with something from Y and Z after repeated attemps.

I have had a junior dev claim that someone must have changed their code overnight. I decided that there were a couple more possibilities before going down that route of inquiry.

Yeah I often try to double check things like that before asking for help. Other wise there are too often silly things wrong like config settings not pointing to the db I think they are. But still end up with egg on my face far to often.
