Pros
AngelHack has been one of the most challenging and rewarding professional experiences of my life. I've worked for NASA Ames, Stanford University, University of California Irvine and many other top-tier organizations and AngelHack ranks right up there with all of the above. Prior to my employment at AngelHack I was a fairly non-technical person, but after two years, and due to the mentorship I've received at AngelHack, I am very comfortable and confident communicating to a technical clientele and developer base - as a minority women I'd give AngelHack a gold star for putting more women into the Bay Area tech scene.
Cons
AngelHack is a startup environment in every sense of the word. Employees that are the happiest here are able to fail fast, learn from their mistakes and pivot easily. If you love a hierarchy then this also might not be a fit - each individual is seen as an integral part of the whole and bears the responsibility as such.
