Vantaggi
Lots of cross-functional interaction. Work on the #1 products that influence the lives of hundreds of millions. Many great managers especially at the topmost levels. Plenty of smart people. A "cool" atmosphere with beer bashes and famous bands coming to visit. All the comforts of a large company, yet maintains an energy of execution similar to many start-ups.
Svantaggi
Some dinosaur rotten apples in middle management that are nothing more than political animals. There can also be territorial disputes over who-does-what that are usually not properly resolved from the highest levels. People who need to talk to each other are sometimes overwhelmed and have no time, so communication often suffers. The culture of secrecy is often frustrating.
