Pros
Good benefits. Company has a good reputation with customers. Fairly simple and effective performance evaluation system. Loads of professional and competent people in the company.
Cons
There are two kinds of employees at SAIC: the real employees and the "talent." The talent are those people hired from inside government to work on site with government customers. The "talent" are not really treated like employees. No real career development, training, or corporate attention. The talent are really product that SAIC sells to the customer. And like any product, if there is any problem at all with the product or the contract, the product goes in the dust bin. I've been observing some chilling horror stories about SAIC putting these "talent" employees out on the street with no warning and no mercy, even though these people are qualified to do other open jobs in the company. Advice to any one in the government considering taking an SAIC job working in the government: Don't do it. You won't be able to trust the company to take care of you.
