From historical context (and from what I remember), when these Bootcamps came on the scene it was the height of Ruby and Ruby on Rails. And companies were tripping over each other trying to hire Rails developers and there wasn’t much pool to pick from.
These bootcamps came on scene to train new RoR developers and companies were snapping up students even before they graduate, offering 100K+ salary, etc… From what I remember, it was good during the early days.
Well, nowadays, the big for-profit companies have bought these Bootcamps and well… try to extract as much profit from it as they can. — you can pretty much see where this is going.
Also, some of the Bootcamps have closed as the business model isn’t sustainable… or sold themselves to these for-profit companies to remain in operation.
Buyer Beware is what I can say nowadays.
