Pros
Umm, everything. If you like working for a cool company, interesting data, a fast-paced environment, intelligent people, accessibility to upper management, and lots of in-office perks, this is a good place for you. Not to mention working in down town San Francisco, which in my opinion is one of the best cities on earth. There is so much green field to work on in the company, no single person is doing "fluff work." Management is nimble and fast moving, and I have seen analyses turn into real time tracked metrics in less than a week. Dress is casual (though fashionable!). Management sits in the same size desks in the open as everyone else. It feels like a total team effort, and is very transparent. Plus, all the soy milk and organic dried fruit you could possibly want. 100000000000000X improved experience from a consulting firm.
Cons
Vacation time leaves a little to be desired. Is the standard 10 days per year.
