Pros

Great team up to director level. Good place to start career, however not many open positions in US

Cons

Contracts are often unclear not including all needed services, leading to financial overburn. The company relies on multiple tracking systems, creating inefficiencies and frustrations for employees, and prioritizes hiring in low-cost regions, which are known for high employee turnover.
