Pros
You get chance to work with experienced and supportive team. They value work life balance and always want you to grow. In case you are on bench then you get opportunity to select project based on your interest.
Cons
Less salary, WFO mandatory. If you are not visiting office then your salary gets impacted. Formal clothing is mandatory. You cannot wear casual (expect Friday) in TCS. Recently TCS migrated to Google Workspace, and this migration is not helping at all. Because not all the employees got migrated to Google Workspace, most of them are still using Microsoft products. In my case, I don't have access to teams, so I'm not able to connect with TCS HR or any other ex colleagues. Because they are still using MS teams and not using Google Chat. All the corporate sessions are being scheduled on MS teams, so what's the point of migrating to Google Workspace. And if you want access to MS products then you need to raise request only if your project management ready to give you access to MS products. ITS PATHETIC.
