Free tool · no sign-up · 3 interview rounds
Generate AI-powered TCS interview questions for all 3 rounds. Process: Online Test (NQT) → Technical → HR. Optimised for campus placements and fresher hiring.
From our curated bank of 12 TCS-specific questions. The generator produces fresh AI-tailored questions each run.
What is the TCS NQT and what sections does it cover?
Tip: The National Qualifier Test has four sections: Verbal Ability, Reasoning Ability, Numerical Ability, and Programming Logic. Scoring in the top band unlocks the Digital/Prime track with a higher package.
What is the difference between TCS Digital and TCS Prime? Which one should you target?
Tip: Prime (UG ₹9.09–9.30 LPA; PG up to ₹11.80 LPA) demands strong DSA and coding; Digital (UG ₹7.09–8.04 LPA) requires solid aptitude and basic OOP. Target Prime only if you can solve LeetCode Easy/Medium within 30 minutes under test conditions.
Explain the concept of polymorphism with a real-world example.
Tip: Use the classic shape/area example but frame it around a real system — a payment gateway processing CreditCard, UPI, and NetBanking objects through a common processPayment() interface.
Write a program to find the second largest element in an array without sorting.
Tip: Maintain two variables (max and secondMax). Single pass, O(n) time, O(1) space. Handle edge cases: all elements equal, array length less than 2.
What is a deadlock? How would you prevent it in a multi-threaded application?
Tip: Deadlock requires all four Coffman conditions (mutual exclusion, hold-and-wait, no preemption, circular wait). Prevention: consistent lock ordering, timeout-based lock acquisition, or using tryLock().
