Cognizant Interview Questions 2026: GenC, Technical & HR Rounds
Cognizant hires freshers across several programmes with different technical expectations. The interview tests whether your fundamentals match the track you applied for. Prepare for your track, not for a generic list.
Know your track first
Fresher hiring at Cognizant is commonly organised into programmes with different technical expectations (for example, a standard track and higher-skill tracks with tougher coding). Your interview depth usually follows the track. Experienced hires get a role-specific technical round and an HR discussion.
Selection steps and test sections change between hiring drives. Always confirm the current pattern on the company's official careers page or your drive invitation before you prepare.
Technical questions to prepare
- Explain your project end to end. What would you improve now?

- Explain joins in SQL with an example query.
- Write a program to count vowels in a string / sort an array without built-ins.

For higher-skill tracks, also expect data-structure questions such as stacks, queues, trees and basic time-complexity analysis.
