The camp I went to was very small and went under after my class graduated. There were just 4 of us in the class. 2 of us now are devs. The other guy who became a dev had a good amount of IT experience coming in, but needed more hands on work with development. The other students just weren't picking up the stuff fast enough and quickly fell behind and didn't recover. I have met a decent amount of people from other camps that had similar experiences, sometimes coding isn't for everyone.
After graduation, I had to do a few more months of solo studying/project work before I reached hire-able level. I got lucky and got hired by a startup that needed a junior dev ASAP. I had a great boss at this startup and learned a lot while also getting the chance to work on features.
Now getting work is easy because I have worked before.
TLDR: You have to put in more work than just the bootcamp to go from no experience to hire-able. And some people just aren't made to be devs, and they may be able to get into a boot camp but they won't be able to contribute when hired. Hopefully I don't come off as conceited/cocky, but that's just my 2 cents.
