Pros
When I first came to DIA, I loved my job. I was in a excellent office and thoroughly enjoyed my work. The overall mission is appealing. Similar benefits to working for other government entities (paid holidays, benefits, fitness programs, work/life balance initiatives, etc). Job security (aside from furloughs).
Cons
Several reorganizations later, I am an in a dead end job as far as career growth goes. Management is hit or miss. Way too many GS 14s and 15s that the Agency doesn't know what to do with. Little desire among leadership to align personnel to jobs that make sense and best leverage their skills. DIA's mission overlaps with other similar government agencies, which all seem to do the job better. Fewer resources than other similar government agencies. HR is archaic. The military culture means that a new director comes in every 2-3 years and "shakes things up" to get promoted, throwing the agency into turmoil. Budget cuts have come down hard and exacerbated all issues.
