There is also market saturation. My brother took the GA bootcamp in 2013, I took it in 2014. The outcomes were drastically different because their hiring partners/relationships couldn't keep up with their output. When he took it, they had a speed-dating event at the end of the course where employers had already signed up to take on an intern, i.e. 100% job placement. One year later, my class had nothing more than a meet and greet. Less than half of my classmates were hired through that event. I can't imagine the outcomes are any better now.
