Pros
I was lucky to work out in the Playa Vista office for the first year and half and then worked from home mostly for another 1.5 years, this may not be the case for most other employees especially for those who work at the main offices.
Cons
Lack of communication between departments, which often resulted in misunderstanding and contradictory decisions. Toxic office politics, one of the worst working environment if ever experienced, I wouldn't have been able to stay for 3 years if I weren't working remotely. Too many people in the management roles, not enough people who actually do work. Many people are not capable of performing their jobs, the lack of knowledge plagues the company. These are the 3 main things that generates unnecessary chaos and stress, and it is not a healthy work environment at all.
