I feel like most bootcamps are bad, and the metric I measure it by is how many people actually end up with careers. Sample size of friends, coworkers, and coming across random profiles on Linkedin or Twitter or whatever.
Hackbright is the best one from what I've seen when it comes to placement and career retainment, and it's free too, but it's only available to women. Hack Reactor seems ok. App Academy seems ok too. DevBootcamp seems like it used to be ok, but is now bad after it was sold.
Which other bootcamps have you hired people from?
