Pros
Perfect employer for moralless, micromanaging masochists who like watching rocks grow. If you've ever wanted to work 60 hours in a week on a proposal then get ordered to work weekends for not doing enough billable work, this is a great opportunity. If you have an advanced degree but miss life as an undergraduate intern, Cadmus works at just the right level of sophistication. You'll spend months doing mindless data entry and making minor formatting adjustments to documents. The culture is really supportive of people who distrust others, and like demanding compliance on the smallest issues. If this describes you, you'll be promoted fast. Just avoid being supportive of other people; that's really frowned upon. Also great for small government advocates: Cadmus seemingly exists to leech as much money from the government as possible.
Cons
Multiple employees have been hired to positions they did not apply for to do work they do not enjoy and are not qualified for. No opportunities for professional growth. Salaries are significantly below competitors and public sector consulting generally (If you're interested in Homeland Security consulting, go to Hagerty Consulting or CNA. They pay better, are more prestigious, and have better reputations.)
