Mars is a place where you work in a completely open environment, similar to what you see in start-ups or in newspaper rooms on TV. However, it is completely quiet so you can hear someone break out in laughter across the vacuous room. People create their own space by limiting their participation with other groups. \
Mars is built in silos and people do not care about what is before them or after them, only what they can control in their area.
This creates a challenging work environment for creating change. People do not show up for a scheduled meeting unless you call and remind them the week, the day before, and the day of the meeting. It's the most bizarre thing.
They also fire the lowest performing %5 no questions asked, so it also create a very competitive environment where people hold back information.
