Pros
The only positive thing I can say about Quorum is that you will get to work closely with some really good people. From the Manager level down there are a lot of genuinely nice and dedicated young folks.
Kontras
The company suffers from ruthlessly inept management. I was there 2 years and not once did I see a picture of the CEO, much less an in person meeting. Quorums' problem is that all upper management is inbred and invisible, with no meaningful experience outside of Quorum. As a consequence they have very limited skills when it comes to managing people. Another big problem is the disconnect between the sales teams and the folks who have to deploy the systems. The sales team will estimate a job at X hours while the folks doing the implementation need at least 2-3X to complete the work. This derives from the fact that (1) there are no standardized tool sets in place for configuring their products, thus everything is done from scratch, (2) they often throw inexperienced resources into the mix and hope they can accomplish the task, and (3) they have an attitude that all projects are time and material projects, thus they have little commitment to honoring the original estimate. The system, as they have designed it, is unsustainable. It is too resource intensive on the front end for deployment and too resource intensive on the back end for support. That type of model only works when a boom is going on, but will collapse when the market takes a downward turn.
