Pros
As in many other reviews, I have found the company benefits to be very good. The retirement program has continued to provide matching even during the current economic downturn. Cost of the healthcare plans have increased somewhat during the years I have been here but we have maintained most of our coverage without a succession of double digit increases year after year after year.
Cons
Across the whole of the company, the company culture seems to suffer from a multiple personality disorder. Sponsored ratings of the company as a place to work are high but some groups do not fit this description at all. The primary culprit is middle management. To be fair, this is not the norm. But the choice by upper-middle and senior management to not get involved allows some individuals to set up fiefdoms where they bully their staff, siphon off the best work and pursue their own personal agendas. The best advice I can give to someone considering working at MITRE is to do everything you can to avoid one of these groups.
