The offices are not cohesive in their appearance. The San Diego office is an open-design office with cubicle walls only several feet high; the Virginia office is the most corporate-looking office of them all but lacks a fun office culture due to the high cubicle walls and the many private offices; the New York office is a multi-purpose space converted to an office space that does not look like a technology company. It would be better to have offices that give a corporate feel while also maintaining a start-up technology company atmosphere consistently throughout the entire corporation.
The company's offices and employees are each siloed in their own bubbles unless an employee or two from said offices actively collaborates with employees elsewhere. You may never know what your colleague looks like unless he or she has personally uploaded a photo to his or her profile. Many employees have not uploaded a photograph. This causes a significant communication barrier. Many other companies reasonably require their employees to have a corporate photograph taken upon hire.
The open-floor, low-cubicle wall concept may be the new thing many companies are trying but it must be implemented correctly to be successful. It is odd and uncomfortable to have an active walkway BEHIND employees desks. The Virginia office has this done right but at the cost of openness. The San Diego and New York office may need to rethink this design. It is very weird to approach people's backs and begin conversations while inadvertently looking at their computer screen instead of their face. Desk configurations should ensure that all employees are facing hallways instead of facing away from it.
