Pros
Smart people - we're hooked into the London, Bay Area and Seattle tech world. Personally, I feel I've grown as a engineer in my time at Quantcast, directly through engagement with peers (smart people).

Great perks - all meals catered (rare for London), strong social culture (and budget for offsite activities) - Relaxed office culture - access to all the toys AWS has to offer.
