What TCS Digital / NQT asks in the DSA round
TCS NQT tests aptitude, verbal ability, reasoning and programming logic. The coding section stays in the easy-to-medium band but the aptitude bar is real.
Across the 287 questions on this page, the weight sits on these patterns:
How to prepare for the TCS Digital / NQT interview
1. Start at the top of the list above. The patterns are ordered by how often TCS Digital / NQT uses them, so the first two or three buy you the most coverage per hour.
2. Solve by pattern, not at random. Doing eight dynamic programming problems in a row is what makes the ninth recognisable in an interview — jumping between topics does not.
3. Tick problems off as you go so the gaps are visible. The per-pattern counts tell you which TCS Digital / NQT topic you have actually covered.
4. Write the approach before the code. TCS Digital / NQT interviews are judged on the reasoning as much as the working solution.
5. Pair this with the pattern guides when a topic is new, and the system design sheet if the role is senior enough to have that round.
6. If this is a campus or off-campus drive rather than a lateral move, the placement preparation guide covers the stages around the DSA round — aptitude, core subjects and the HR interview — in the order they actually happen.
