Pros
A large percentage of employees are former military so veterans will find a very familiar atmosphere. Not afraid of giving new employees important responsibilities. Better than average commitment to employee growth.
Cons
Definitely two classes of employees: Corporate - who are secure in their jobs and Contractors - who are jettisoned as soon as their government contract ends. Recruiting Managers and Human Resource department are not always in-synch - prospective employees should ensure everything is in writing and expect to reject the first couple offer letters as being to generic. Regardless of what anyone tells you, if you don't get it in writing you're not going to get it. Depending on which division you work for, vacation/paid holiday benefits are below average,
