Pros
Depending on your BU and site budget, SAIC offers training and educational opportunities. In fact, you'll find that many employed by SAIC have a great deal of certifications. The fact that these same employees have no real-world experience doesn't seem to bother the customers of SAIC, though it makes for a challenging work day for others.
Kontras
If you don't work at a client site, you have little to no opportunity as far as training or education or career advancement for that matter. Benefits leave a great deal to be desired. The site I work at is about ten years behind on technological advances, yet no one understands this based on the fact that they have been with SAIC for the last ten years. Also, the only qualification(s) needed to become SAIC management concern former military service and the ability to sit at a desk and stare into a computer screen (also, it is preferred though not required that you know your basic shapes and can read above a second grade level). If you meet these requirements, you are golden.
