Pros
SAS campus is beautiful, the benefits and facilities are wonderful, and the general environment (when people are actually going to the office) is an all-around great experience. The people, the coworkers, are generally great, but there are a many cliques who use their tenure or connections to influence and force their agendas on other people — which is not only a poor practice, but their direction is misguided leading to poor decisions.
Cons
People not going back to campus definitely hinders collaboration and team building. Pay is considerably lower than other tech companies, and the "work/life balance" SAS touts is pretty much the standard everywhere now. The SAS that was years ago is a myth now. It's hard to move up through the organization even though they talk about how easy it is to move to and train in other positions internally. Many departments are so short staffed at headquarters that they aren't willing to let people grow or move to other areas. There is a clear bias given to certain employees and HR is deplorable. Many older, talented employees who were with the company for decades were given early retirement packages or risk losing their jobs; the company is hemorrhaging experienced talent.
