I did not attend a bootcamp, but I have known a few who have. Of them, there were two types I found most successful.
1. People who were also spending time learning on their own while working for peanuts (or even free) to gain experience.
2. People who were supplementing their existing expertise (outside of computer science) with basic coding skills.
The people in group 1 certainly had a lower salary/years-experience ratio than people from CS backgrounds. The people in group 2 often increased their salary, assuming they learned relevant things.
