Pros
Data Federal's hiring process is probably the fairest of any employer I've encountered in the area - based on merit, promise, and practicality. They move quickly in the hiring process and offer good benefits. They are always looking towards the future in regards to their business and potential career development. I know several people who have been with them for the better part of a decade, and that says something. Negotiations were fair, and I can't say I've encountered a company so focused on staff development. I have full faith in their future.
Cons
Because it is government contracting and inter agency agreements, sometimes things can move slowly, but in comparison to other SMEs I've worked for/with, Data Federal is pretty responsive considering. The COO takes on a lot to ensure things are fair - in regards to things that typically come up in government contracting.
