MITRE reviews

Like any big company, there are politics. Since this is government work, there's more politics than most. Pay is also not always competitive with industry, specifically where software engineers are concerned. Each super-organization (called Centers) within the company runs like its own business, which leads to unrest and in-fighting within the company. People are evaluated differently from Center to Center, values are different from Center to Center, and there's lots of turf wars.

Depending on what part of the organization within which you work, your experience may be miserable. No standards with regards to management and treatment of employees. Some people work hard, some people barely work at all -- and some people who do close to nothing - make large salaries, hold positions of high responsibility, and go completely unchallenged by the "system".
