They focused pretty heavily on soft skills, like communication and pairing, and also somewhat on generic software construction ideas, on thinking through a problem and breaking it down into its component pieces. The curriculum used JS and Rails, although I didn’t feel that I had much more than a surface familiarity of either by the end of the cohort.
I think that, in general, if a bootcamp has a decent focus on software construction and doesn't totally fall down on teaching you the technical stuff, you’ll probably be prepared to work, at least, as a junior dev. But, you can't just rely on a bootcamp. You really have to spend a lot of time (like, a ton of time) learning on your own, writing code and reading code others have written.
Since then, I’ve been working steadily as a mostly front-end and sometimes full-stack developer.
My cohort was a little weird, people went on to do other stuff, like start their own bootcamps. But, I believe most of the people who wanted to be devs are still doing just that!
