As someone trying to hire web developers, it looks to me like Bootcamps are more like finishing school than trade school. Candidates that come out of a bootcamp have learned how to signal membership in the Silicon Valley in-group. Their resumes have all the right keywords, and refer to "projects" they've worked on, built with all the frameworks and tools currently in fashion. They've practiced their interview techniq…
That's all the more reason these bootcamps should be way more transparent than they are.
There are people for whom the cost of attending such a bootcamp is enormous - they might spend their entire life savings or finance the attendance of such a camp, putting them in a bad debt spiral. And while many of the camps are selective and only hire people with previous development experience, I'm sure there are some with more 'flexible' standards so to speak that will happily take your money, regardless of your background.
One of the things they could do to make it more transparent is to signal that software development may not be for everyone - just like being a doctor or an athlete or some other profession that requires extreme passion and dedication.
