Just got back from 3 weeks on the East Coast. After 8 months in Seattle, I had completely forgotten what hot & humid feels like! (For those unfamiliar with East Coast summers: like walking through a warm marshmallow.)
I spent a week of that time at the Google office in New York City. It's an incredible facility - the building takes up an entire Manhattan city block, and the view from the cafeteria on the 8th floor is truly remarkable.
The culture is definitely different than either the Kirkland or Mountain View offices - still Googley, but with much more of an urban feel. If this sounds interesting to you, you can find out more about Google NYC here.
