Pros
Good if you're a junior person who doesn't know better about what a good corporate culture looks like. Or if you're from NetApp or EMC, in which case this is a step up from your prior dinosaur companies.
Cons
Take a look at the "Executive Leadership" page of Pure Storage. What's the pattern here? In a place where the majority of individual contributors are Asian or Indian, the entire 4x5 grid of 'leadership' is a series of white men with a token woman. Is diversity a problem here? By all means- it's a joke. Also, nothing exciting happening, but lots of kool-aid being slung around about culture, with excited high-fiving and salesmanship. Don't believe the hype about advanced management capabilities. It's just a pretty UI. If you're a talented engineer why not work on public cloud at AWS, Microsoft or Google? Or Dropbox or Box?
