Pros
The company's commitment to culture is unfathomable without being in the company. Everyone eat lives and breaths the awesomeness that we give to each other. Yeah it's a little funky, but we're fundamentally a service company, and the best way to give service to our customers it to give service to each other. There is a lot placed on the 'intangible' in Rackspace, but that's what makes it unique, and better. The business has a good strategy, and it's very open to the employees. I sincerely trust upper management. That's _weird_.
Cons
If you don't fit the culture, you don't stay long. I've had good friends leave because it just wasn't the place for them, or they just didn't click perfectly. Politics happens, and there's fall out because of it, but at the same time the company as a whole moves forward.
