What I see is the developer who's left after multiple rounds of cost cutting layoffs and subsequent exodus of anyone qualified, that knows they are only there because they are willing to work for the least amount of money, and are willing to endure abuse from their sadistic manager, not knowing how to systematically debug the mountain of accumulated issues, and keeps trying random stuff hoping that anything will somehow work.
Scattershot troubleshooting is the most frustrating way of looking for solutions, can't imagine why that would be any sane persons first option, or even before asking for another set of eyes.
Not really relevant to your comment, just that I've seen that myself a few times and it always frustrates me. Especially if the person does multiple changes so it's hard to find the origin of any new issues
Tell me about it, all the juniors were doing it at my old job, and I was usually the one tasked with fixing their shit. And since we basically didn't do any form of mentoring (including code reviews) it was such a pain in the ass to get them to change their ways
Tell me about it, when the roles are reversed and nor the manager ex-dev nor the older dev care about good programming practices it's a far west where the junior desperately tries to become the dictator of a ruleless country
