Pros
Pretty responsive HR though not very useful for assisting in conflict resolution. Training platform available. Coworkers from the same company that worked in different teams within the contractor org had positive experiences.
Kontras
I imagine your experience with the company will depend on who they contract you out to. My on-site team was very busy and thus the "unlimited PTO" promise was just a way to NOT be able to take much PTO, and you are basically at the mercy of the approval of the onsite supervisor. You are also in this weird limbo, because the onsite supervisor has basically all the power over your duties and time, but are released from any issues that arise since they are not "your boss" and therefore don't have the power to really create any positive changes. Any changes usually mean heavy negotiations between the contractor and Guidehouse, which requires both the contractor and Guidehouse be willing to do so. Additionally there is not really a good "raise" or increased compensation policy, esp. since they claim they need to abide by the government raise caps,... so you kind of get the worst of both worlds. Finally, it seemed to be quite difficult to find a way to improve your situation, as their main goal is to keep the contractor happy, so again, if you have a high demand team there is really no incentive to help you get out from that team and find a better fitting role within Guidehouse, nor any backing to help you arrive to a better situation within the existing team.
