Vantaggi
SAS' commitment to work/life balance is unmatched in this area. They are trailblazers in this arena and continue to be at the top of the best places to work. SAS is particularly good for employees with families.
Svantaggi
Unless you're making software, your job is not guaranteed. Dr. Goodnight is very focused on numbers--you're either making him money or costing him money. If you're the latter, consider yourself in trouble. You better bring something substantial to the table if you're in a non-revenue making department (particularly marketing). SAS is also very focused on benefits for employees with families. Young professional, particularly those with no kids, may find that the benefits gloss over you a bit. As a private company, you're not going to get rich at SAS. SAS is the kind of place to look for once you're ready to settle down with your family.
