I came from one of these bootcamps, GA specifically. I have a job at a large tech company in NYC as an junior developer and have been here for almost a year. GA set up good expectations for us and they definitely did not promise us 100k a year! There is also no commission that my company had to pay to hire me. I spent about a month looking for a job. Everyone in my class had a job by 2 months after class was over, so I think the demand is still high for junior talent. I think it works for companies that want to hire developers that they can really shape but have proven their ability to learn. I really loved my time at GA and I have a totally different life than I did a year ago.
