I'm more curious about what's generally covered in the curriculum. Three months doesn't seem like enough time to learn much in depth, even if you're a total workaholic.

The basics and that's about it. IMHO, these schools do a very big disservice to the people they pretend to help. I think it's particularly bad for woman and under represented groups looking to springboard into technology, as it sets an unreal expectation.

This could be selection bias: companies have other channels to acquire junior engineers, so they don't advertise these positions.

I'd like to know this too. The few places I've worked that hired from these schools quickly let folks go and never went back.

I know a few left tech altogether.

Startups, Web-Design boutique/consulting, freelance/contract. Less likely the big guys (Google, MS, Apple, Amazon).

Yes majority in local consultancies and small startups, but generally anywhere: Facebook, google, linkedin, paypal, square, tumblr [1], thoughtbot, pivotal, artsy, betterment

You can only get away with hiring juniors is you're very big or very small - between the two the overhead of training someone up is a significant short term burden.
