Vantaggi
You can get experience in how a big enterprise work and how organized a company can be. There is opportunity to learn about highly scaling applications but technically the learning will be stopped in one or two years because no new technology come up. Very good work life balance. Less stress if you like a relaxed work.
Svantaggi
Leaders are crappy and are at the mercy of the director for deciding even the smallest things. Director is good at bringing work to trivandrum office but is not good at his approach to employees. Very judgemental and discouraging. Plays crappy games with employees. HR is non functional and very confused. When some issue arises, they don't know how to solve it in a good way and always try to favour the management, even when the employee has a valid point. Unless escalated, HR never hustles for the employee.
