Avantages
MITRE has great corporate policies of valuing their employees. They have great employee benefits and internal resources to create high-quality products, and to serve the government well. I believe many divisions within MITRE are great places to work. Collaborative environment with mostly very bright people.
Inconvénients
A couple of weeks after the CEO of MITRE proclaimed to all employees that the company's last resort would be RIFs, 100 or more people were RIF'd. This is indicative of the unmet promises at MITRE. The leadership is changing, and the great corporate policies no longer hold true. My personal experience at MITRE was horrible -- and I do mean horrible -- due to the politics and morale. People don't talk to each other in the hallways. It's a very unfriendly place to work. Direct supervisors give no direction to employees. Politics govern most decisions, and very hostile work environments are well known -- and remain -- while senior management does nothing about it. I think MITRE does an excellent job of thoroughly outlining project requirements, procedures, standards, etc., for projects for customers. But, to my amazement, I saw no evidence that MITRE has ever done this internally. They need to listen to their own advice!
