A great place to work in a great moment of mankind history
Pros
if you look back in history you will not find a moment of such changes as the one we are living right now. The digital phenomenon is still expanding rapidly, creating a world more open and connected. Right now, Facebook is the main company driving that mission, giving power to the people to create a more open and connected world. Being able to add value in a company that is consciously pushing that goal is really satisfying. you end each day knowing that you are doing your best for a good cause and that the journey is just getting started.
Cons
the main challenge is to adapt yourself to work in a really big structure and knowing that is growing more and more. It tends to be difficult to reach the exact person that you are looking for at the right time.
