TL;DR

TCS fresher hiring usually runs through the TCS National Qualifier Test (NQT), then technical, managerial, and HR interviews, with Digital and Ninja tracks differing in cutoff and difficulty. The fastest way to prepare is to combine aptitude, coding basics, project explanation, and HR readiness. OphyAI Interview Coach helps you rehearse TCS technical and HR questions, while OphyAI Interview Copilot helps you keep live answers structured.

Quick Answer

For 2026, prepare for TCS by mastering NQT verbal, reasoning, numerical ability, programming logic, and one or two coding problems. For the technical interview, be ready to explain your final-year project, OOP, DBMS, operating systems, networking basics, and one primary language. For HR, prepare relocation, shift flexibility, “why TCS,” and teamwork answers.
