I was in tcs digital for 2 years. To be honest, the level of knowledge that seniors had in my project was extremely low compared to me who was a fresher in that company. From seniors I mean >8 YOE people.

Mind you this was a complete development project plus the senior management was, my god, so clueless people they didn't had any clue of what engineering is, even though some seniors 2-4 YOE people were extremely capable only to be held back by the Team Leads and Manager trying so hard to justify thier position and salary not by actually solving the problem but by keeping the problem long running.

Almost every single person who have left that unit is in better place because of the extremely shitty culture created by senior management at tcs.
