As a matter of fact, in India, engineers mostly avoid service based Indian companies like Infosys, CTS, TCS unless otherwise they are in the extreme bottom end of the funnel (they just need a job) or at the extreme top end (disproportionate high pay). These firms are notorious for their carrot (probable on-site opportunities) and stick (mindless work hours clocking among others) approach, and their typical workplace is full of discontent and frustration. Just for an example, I have known people working there who were trying to game the clocking system by finding a bug that allowed them to leave early provided they clock before midnight from any of the offices which would increase their clocking hours. That aside, these firms are just a small part of the actual tech scene in India, except they have sheer numbers when it comes to the H1B process, which kind of projects these firms as representative entities of Indian engineers.
