Pros
Chance to get exposed to large tech companies
Kontras
You'll likely sit around for months after training and have to deal with them expecting you to always be in constant communication with them and available any hour to answer calls from people in India about projects. The location they give you on your offer letter is meaningless, and they'll use your job security as ways to threaten you to get you to relocate multiple times no matter what personal financial cost it has on you. They'll pay you far under market average, despite being largely in major cities that cost subsantially more to actually live in. After all the time you sit around on bench after training, the odds are whatever project you get put onto will be filled with nothing but grunt work no matter your personal experience or even if you're not the newest person to join them. If you're not Indian, they'll actively work against you and make sure you know they see you as a lesser employee
