Pros
When I first started to work at MITRE (pre-pandemic) there was this emphasis from everyone about work life balance. I was excited about the tuition reimbursement policy and the benefits package was for the most part pretty great (aside from the fact you have to wait 1 year for the company to invest into your 401k).
Cons
Shortly after starting the pandemic hit. During this time finance underwent a transformation of systems which was an absolute nightmare and poorly executed. This resulted in 10 hour days for over 10 months. Senior leadership does not remotely care about you as an employee or about how many hours you have to work to meet the customers needs. Capacity issues rose as HR services failed to fill positions. I am so happy that I left when I did, I have not heard many positive things from anyone in finance since my departure. The finance leadership for the most part was a wonderful group of individuals who were willing to help you grow and achieve new heights until even their plates were too heavy to succeed in their leadership roles.
