Pros
Great creature comforts. Wonderful benefits and facilities, if you have a lifestyle that fits the company's vision.
Cons
SAS is full of the dumbest people I have ever worked with. It is the opposite of a meritocracy. There is no reward for hard work or excellence. People just fill a chair until retirement. Salary, benefits, vacation, even the office you get, all depend only on one thing: how long you've been there. The brightest person in the world could walk into SAS and in 3 years do the work of 20 of their coworkers, and still would make less than someone who has been there 4 years and done literally nothing. I know people who stopped coming into work all together. No one even noticed. The largess of the 25 year monopoly is starting to wear off. SAS does not innovate. They simply are riding out their reputation from the days when they did, and their wealth of recurring contracts. If you are a hard working person who tries to make a difference at their job, SAS will chew you up and spit you out. If you were a "D is for diploma!" kind of college graduate, and you happen to know somebody who already works at SAS, Welcome! It will be the best career you can get until you retire or SAS pisses off enough customers to no longer be able to drag along all the dead weight, whichever comes first.
