Pros
Great benefits, including great healthcare insurance, onsite healthcare center, onsite intramural sports, onsite daycares, onsite cafes. Work environment is like a college campus including lots of walking trails. At lunch, there are employees working out in the gym, playing soccer or ultimate frisbee on fields, playing basketball, volleyball, handball, or cardiac routines in the gym, playing water polo in the pool, friends and family including their children, eating at the beautiful cafes. A culture that supports a healthy worklife balance. For now, you can optionally work from home. Employees are encouraged to work in different positions, so there are opportunities for lateral and upward moves, especially if you are in a lower position. There are a lot of smart people working there.
Cons
Salaries aren't as competitive as some other software companies. Career ladders are pretty short, so don't expect frequent promotions. Cooperation and communication between departments isn't great, so there can be overlap of different departments unknowingly doing the exact same thing, or waiting a long time for another department to do something you need to do your job. The future of Sas as a company is not clear.
