Pros
The people who are attracted to TechChange are nothing short of idealistic, educated young people, and my experience working with them was wonderful, to the extent that they were supportive, creative, empathetic, and hard-working (despite being ill-compensated and undervalued. And, lied to.)
Cons
TechChange did not value any ideas contrary to management's cemented conception of success. Clear-cut, fact-based strategies were ignored and employees fired after offering constructive-criticism. This org exists in a decently competitive market where the CO's ideas could honestly flourish if properly implemented and time invested. I believe TechChange had a competitive edge based on the fact that good, smart, and energetic people applied to work there, from various backgrounds. However I found the hiring environment to be extremely elitist and I suspected preferential treatment for a particular alma mater. Managers were not honest, made promises to employees which were not kept, and falsely promoted a "social good" agenda when really, the patriarchy in the air stank, and those leading your teams were hardly compensated for their energies.
