I have encountered a number of people who share your sentiment, that attending a bootcamp is a negative signal. I went through one of these bootcamps after a few years of learning on my own. While it was an awesome experience and I learned a lot, I find it necessary to pretend it never happened - it's as if the years I spent teaching myself and my passion for the subject are undone by association with a bootcamp.
Have you not encountered people with the opposite sentiment? I'm in your same situation (but I haven't gone to a bootcamp yet) so I'm wondering what I should do.
I suggest not going, but at least be careful which one you pick. We've interviewed a bunch of people from General Assembly LA and none of them have the right kind of experience for us to hire, so now we don't really consider anyone whose only experience is GA.
Have you tried applying for jobs? Working anywhere >> going to a dev bootcamp (with the possible exception of NYC Hacker School, which seems incredibly impressive and self-motivated)
