Pros
I enjoy the work-life balance. The flexibility I have to address family issues and not have them conflict with my work responsibilities, such as working from home if need be. My boss takes the time from his busy schedule to listen when I have a problem or issue, even if it is not work related. I believe that the salary ranges are commensable with other companies; I like the flexibility I have in work hours. There are time when I need to come in early or work late to make up time from an appointment and I don't get flax behind it. I can't say enough about working at MITRE. I recommend everyone I know from past and present work experiences.
Cons
If there are any downsides, they have not affected me in the 5 years I have worked for MITRE. I just love it here. I am an upbeat positive individual so if there were downsides, I would find up sides out of it. I think people who find downsides are negatives individuals to begin with so in their world - nothing is sanctioned. What more could you ask for in a company, flexibility, great salaries, benefits, open-doors (no-bullshit), the opportunity to speak your mind without prejudice or retribution. Here at MITRE if you have a dream or and idea - it is expanded upon - you can make dreams a reality here at MITRE so again, I ask you - What downsides?
