Great team but occasional overnight stretches needed - Onsite Tech Lead Tata Consultancy Services Employee Review

Large client base. Talented people, have "cracked the code" on offshoring development and support.

For anyone used to working in US-based firms, the culture and politics will be difficult to understand and navigate. Internal policies and systems focus on the offshore delivery center model. Roles in the US do not fit into that mold, and obtaining approvals for simple expenses can require weeks and insanely high approval chains given the size of TCS. I needed approval from a global division head (a CEO direct-report) just to pay for a short training course. Missions of different departments are not clearly defined, so overlap and conflict are common.

Strong learning opportunities, exposure to large-scale enterprise projects, supportive colleagues in many teams, and access to training resources that help build technical and professional skills.

The experience can vary significantly across projects. In some teams, onboarding and knowledge transfer are not well structured. New team members may struggle if documentation, mentorship, and timely support are lacking, which can impact performance and confidence.
