Right, this is top edge of bootcamp folks, and these guys do get hired and do succeed.
You're talking about folks who completed a tough STEM degree and then switched to tech. These are the folks you know. But these are already pre-selected people. They were already in the top 1% "most likely to succeed" before they even set foot in the bootcamp.
You're missing the 99% who never went to college because they lacked the desire or ability to learn, then drifted into some skill-mill that took their money.
These are the majority of bootcamp graduates.
> I've also seen people with non-quant backgrounds land ok jobs doing menial coding (e.g working at an accounting firm on database stuff)
Ten bucks say these were non-quant college graduates, and probably a good college too. So now we're not talking about the top 1%, but probably top 5%.
What you're considering "menial coding" is just simpler jobs, but not really simple or brain-dead. That stuff gets automated... often by startups staffed by folks who went to Stanford CS.
