Pros
Some very sharp and motivated people work here. They have developed significant traction in their marketplace - essentially dominating the competition. Many people are around from pre-public offering days, yet there is significant change (as always) in the workforce. Teams tend to be small, self-sufficient, and motivated to define and drive their work forward. The stock continues to be strong.
Cons
Once extremely strong in culture, things have started to get challenging. The pressure of a large installed base, aging technology, and market demands (you make a contract with the devil when you go public - either grow or feel pain) have caused some significant strains. In an effort to orient the workforce toward the future, some of the magic has been spread thin. Acquisitions and the regionally dispersed workforce puts strains on communication and coordination. Many company veterans are finding now a convenient time to depart.
