Pros
While the salaries are insulting the benefits aren't bad. If you are lucky you will be hired for a long-term placement in another organization that gets you out of the Rockville office for all but the painful, yet mandatory monthly meetings.
Cons
Too many to include a complete list, but on top of the low salaries, there are practically no opportunities for real advancement and few opportunities to learn skills necessary to advance elsewhere (such as using current collection management software like ArchivesSpace or any digital asset management skills other than perhaps basic scanning and recording info in a basic database). I would also agree with the reviewer who described the senior management (at least some of them) as incompetent and unprofessional and the rampant gossip and favoritism.
