Pros
This place used to be really great in terms of culture and work-life balance and career advancement but that changed in the last year. Base salary is good compared to some other larger federal contractors. You usually only have to work 40 hours a week but longer weeks are becoming increasingly common especially if you're on a new project or proposal. Healthcare benefits are okay but don't expect any help from from HR if you're disabled or on leave or need any support beyond the bare legal minimum. There are some talented people there but many of the people who made it what it is have left or been fired.
Cons
Pay and promotions and many benefits are frozen because of massive layoffs and loss of revenue. The company is not stable and leadership is not good at federal sales or contracting or leadership through hard times. They took extreme risks with a huge tax bill and attempts to grow too quickly, lost half their revenue on a contract with months of publicly documented signaling in advance that they either missed or ignored, chaotically laid off 1/3 of the company, and destabilized many remaining projects by laying off critical staff. If you criticize leadership, company policy or the People & Culture (HR) team, they will ignore you until they find a way to fire you. People who were critical of bullying behavior and non-inclusive policies or people who took "too much time off" (sick time was previously unlimited, vacation is accrual) were issued performance improvement plans and / or laid off regardless of their job performance or their importance to their projects. Do not trust HR here. The culture of transparency and candor and human-centeredness is disappearing with the people who defended it getting laid off or pushed out. It's been replaced with relentless positivity and corporate spin and diverting accountability. Check the responses to the recent Glassdoor reviews and keep that in mind.
