Pros
Great people at all levels. Honestly I have never worked with a group of better people who come from a fairly wide experience base for an organization with such a narrow focus. I think the company does a very good job sharing gains with even low level employees such as myself. I work with an intergrated contractor / military team and have made great friends at work in in both the service and the company. I can talk honestly with my managers and they give me honest answers. I really like working for SAIC, they are a cut above any company I have worked for in the past.
Cons
None really. Timekeeping software is a bit tough to work with at first. Really any annoyances I have had have come from working at a remote site and having to deal with an HR department that is hundreds of miles away. They do a great job but dealing with issues by telephone and email can be more frustrating than being able to walk upstairs to an HR department and talk to people face to face. The online performance evaluation program can be a bit of a pain to an employee who is used to completing their annual performance reviews face to face also but works pretty well for something of its type.
