Calling all bootcamp grads or those currently in bootcamp! I need your help!

A couple of my friends are looking to make a career switch to coding and were asking me about Bootcamps. I have heard of Flatiron school, which seems pretty awesome but not much beyond that. One friend asked about this Northwestern University one, which looks great based on the brochure, but I would rather get REAL feedback from those who have done them.

Give me all the juice so I can actually make a good recommendation for the next generation of coders! Please and THANK YOU! 😃

PS If you could include what language or part of the stack the bootcamp was focused on that would be super helpful as well!
