DSG is small firm (around 20 employees) owned and managed by a husband and wife. Their personalities, and their whims, govern every aspect of an employee's life at this extremely troubled place.
Management rests on the central pillar that loyalty to them is more important than competence. But even if you ascribe to this philosophy, you will never be able to please them. Keeping everyone in a constant state of anxiety and tension is a fundamental part of the culture. Work happens their way, when they say … they often show up around noon and stay until late night, and you should expect to keep the same schedule or there will be big trouble for you.
Adding to the strain: this is a federal contracting firm that is almost without contracts. All the attention is focused (and has been for a while now) on business development. So expect to be writing proposals even for projects where the likelihood of success is small. And expect to be working on them at 10pm, midnight, even later ... and on weekends.
Reading this, you may think I simply had a bad experience, but my experience is typical. Turnover is extremely high. DSG seeks out vulnerable people – young employees, those anxious for work, H1B visa immigrants – because they are easier to control. They may offer you a low salary with promises of a review in 3 or 6 months … but keep in mind any review will be contingent upon a sudden upswing in their success in getting proposals, and even then may not happen.
I strongly encourage you to do your due diligence and talk – offline, away from the bosses – with some current (or former, if you can find them … say, using LinkedIn) employees. Avoid this place.
