Pros
1. Trainings are available for most of the technologies and are open to all. 2. Transport is OK. 3. Canteen quality varies by location.
Cons
1. No freedom to work in your area of interest. 2. Biased attitude of senior management decides who can work in which area, not your abilities. 3. Favourism is a major issue based on Gender, cast, culture. 4. Long working hours/No work life balance. 5. Your manager decides your fate here. No transperancy. There is no way to escalate your issues to senior management. Even if you do, the senior management is equally incompetent, so no hopes at all. 6. Employees are forced to work long hours unnecessarily to complete the work long before deadline so that seniors managers can take the whole credit for their own benefit. 7. No matter how hard you work, its your Lead who will take the credit and you cannot do anyting about it because of biased management. 8. Personal remarks/humiliation is a part of day to day communication here. I will not suggest anyone, specially laterals to join cognizant and have stopped referring my friends. 9. Your manager can misguide you while joining a project. The job role specified and the work you are actually doing will be a lot different and its very difficult to get release from a project if you are not your managers pet.
