I have heard about them. The only thing nice about their program is that they already have relationships with employers and by going through their program you already are in a better spot to find employment. They only accept 250 or so students every class session so its tough to get in.
The most important factors employers look at is experience. The key is to find a training program that graduates experienced professionals. Chicago Career Tech does this but I still don't think their program is that great! They just have a lot of connections (friends with some big name ppl)
