This is the most toxic company I have ever worked for, but it's very subtle. I am still unlearning trauma responses developed during my short time here and the only reason I would recommend taking a job here is if you can't find anything else and want to learn everything you shouldn't do. The "core values" sound nice but are not a reality (except for one, "let your geek flag fly", which is somehow still toxic). Employees aren't trusted to do their jobs and every action requires an insane level of justification. Planning is entirely top down and little to no consideration is given to what subject matter experts know. Many poor decisions are made in the name of security (like spying on employees) but the organization's actual security is comically bad. Engineering practices are stuck in the past and although the company claims to do Agile/SCRUM, it's in name only. There is open hostility between the many silos, and some teams have very problematic superiority complexes. Much of the "top talent" here is not good at their jobs and is threatened by, and will resist, anyone competent. Standard practices here are staggeringly inefficient. I believe that the only reason the company is still in business is because their government clients don't have the expertise to realize just how bad the product and company are.
There's also no sick leave. For a company that has "stay human" as a core value, that's pretty messed up.
