My experience has been that a developer bootcamp is not enough for our company, but could probably land you a junior position at an agency. The camps give you a lot of buzzwords for your resume but the actual technical knowledge is skin deep. We have a technical interview, and most bootcamp candidates won't be able to complete it.
If you do try it, remember that simply going into a company afterwords and saying, "I want to learn! See? I took a bootcamp, I can learn!" is not an effective strategy. I've had a lot of candidates try to sell me on how quick they'll pick up on something. Sorry, this isn't a learning hospital. You have to demonstrate initiative and outline your personal learning plan, and convince me you'll be the one in charge of your educational path.
