Pros
Good working facilities within premises. Good for individuals able to negotiate a substantial pay-hike, and looking for limited career growth.
Cons
The GSC entity is structured to be a cost-arbitrage center, and this is reflected in the policies and work culture. The roles are operational in nature, with creative and managerial aspects of a job being retained at onsite locations. I would recommend that folks take up opportunities here only if you do not intend to aim at career growth, and are ok with a tenure based career progression. HR policies unfortunately do not address internal conflicts of interest between teams and individuals. Prospective employees should expect to work within the constraints of redundant HR policies (esp. older employees and GSC senior management being driven by personal job retention).
