TCS NQT interview experience
After the NQT, most candidates get one interview session with technical, managerial and HR parts, often by the same panel. Ninja interviews are short (about 20–30 minutes); Digital and Prime interviews go deeper (often an hour or more) into DSA, projects and newer technologies.
Selection process
- TCS NQT (online test): Foundation (numerical, verbal, reasoning) plus Advanced (quant/reasoning and coding). Your score decides whether you are considered for Ninja, Digital or Prime.
- Technical interview: Self-introduction, project deep-dive, OOP, DBMS/SQL, one small program, and for Digital: DSA, cloud and other new technologies.
- Managerial interview: Why TCS, strengths and weaknesses, situations and teamwork. Often merged with the technical round.
- HR interview: Hometown, family, relocation, documents and joining. Usually short.
