The company is without a doubt the biggest example of "silos" and a "high school lunchroom" with each floor being a different table in the lunchroom. People are treated or looked at differently depending on which floor or team you work on. There is no real attempt to integrate or work on team building to increase the camaraderie in the workplace.
They also on trying to cram so many people into such a small office building and it's getting to the point where people are having to get creative just to have space to put a desk for them.
