TCS Interview Questions 2026: NQT, Technical & HR Guide
Realistic TCS interview questions for 2026 campus and off-campus drives — NQT topics, coding basics, project deep-dives, and HR rounds for Indian freshers.
TCS still hires at scale through NQT and campus drives. Interviewers care less about LeetCode hard and more about fundamentals, clear projects, and whether you can learn on the job.
How TCS hiring usually works in 2026
Most freshers hit TCS through National Qualifier Test (NQT) or a college drive. Typical flow: online aptitude + coding → technical interview → HR / managerial. Role names vary (Assistant System Engineer, Digital, Graduate Trainee) but the evaluation pattern stays similar.
Digital and specialist tracks ask stronger programming; classic ASE tracks lean on aptitude, OOPs, SQL, and project explanation.
- NQT: numerical, verbal, reasoning, and coding (language of choice)
- Technical: core CS + your project stack
- HR: location flexibility, gap years, notice / joining date, bond talk
NQT-style topics that still show up
Expect speed over trickiness. Practise percentage, ratio, time-speed-distance, profit-loss, and seating arrangement. For verbal: reading comprehension and sentence correction. Coding is usually 1–2 easy problems — arrays, strings, or simple loops — not DP.
If your coding attempt fails but approach is clear, write the logic in comments; some panels review approach screenshots from the platform.
Technical round — questions interviewers actually ask
Open with your strongest project. They will ask: why this stack, what you built vs what you copied, how you tested, and what broke. Then fundamentals matching your resume keywords.
- OOPs: encapsulation vs abstraction with a class from your project
- SQL: joins, primary/foreign keys, write a query for ‘students with no submissions’
- DSA basics: reverse a string, find duplicates, two-sum style
- Java/Python: collections vs lists, exception handling, GIL (if Python)
- OS/Networks light: process vs thread, HTTP vs HTTPS, what is an API
HR & managerial — don’t improvise blindly
Common themes: Why TCS? Willing to relocate? Any backlog? Tell me about a conflict in your team project. Strengths and weaknesses that don’t sound scripted. Be ready for ‘walk me through your resume in 2 minutes’ without reading.
If you have a preferred tech (Java/React/cloud), say it once with a project proof — not a wishlist of every buzzword.
How Apply helps for TCS
Paste a TCS or Ninja / Digital JD into Tailor so your summary and skills match the role language (Java, SQL, SDLC, communication). Use Interview prep with company set to TCS for a practice set aligned to fresher rounds. Track similar IT-services openings on Jobs.
