I hired one. She got rejected from my company for a developer position, but I hired her for my team anyways for a hybrid business development/programming role.

This was ~2 months ago; she's learned enough in two months that we're going to hire her at the end of her contract as a full-time Rails developer. I'm not sure that the 10 week bootcamp was enough for her to pass our screening, but in the two months she's been here she's more than proved herself as capable.

As a business guy, I can't comment much on why she was denied originally, but so far it's worked out.
