1. Passage: 'Cognizant's GenC program trains fresh graduates in technology, soft skills, and professional readiness.' Which skill is NOT mentioned? → Project management
2. In a row of 40 students, Priya is 15th from the left. What is her position from the right? → 26th
3. What is a composite key in a relational database? → A primary key made up of two or more columns to uniquely identify a record
4. Cognizant uses 360-degree feedback in performance evaluation. What is the primary limitation of this approach? → Rater anonymity can lead to inflated or biased scores
5. A candidate responding to a Cognizant case study interview spends 80% of the time explaining the problem and only 20% on the solution. What does this indicate? → Inability to prioritize and manage time under pressure
6. What is a primary key in a relational database? → A column that uniquely identifies each row in a table
7. Which data structure follows the Last-In-First-Out (LIFO) principle? → Stack
8. Two numbers are in the ratio 4:7. If their sum is 99, what is the larger number? → 63
9. Which interview round in Cognizant's process is PRIMARILY designed to assess cultural fit and values alignment? → HR/managerial behavioral round
10. Which evaluation strategy is MOST aligned with continuous improvement in Cognizant's agile project teams? → Retrospective-based assessments at each sprint end
11. What is the primary goal of Cognizant's Acceptable Use Policy (AUP) for IT resources? → To define permissible and prohibited uses of Cognizant IT systems and assets
12. What does REST stand for in web services? → Representational State Transfer
13. If a Cognizant project dashboard shows 'tasks completed' rising steeply in week 3 only, what type of variation does this represent? → Irregular/random variation
14. Which of the following BEST demonstrates 'upward communication' in an organization? → An employee reporting project risks to their manager

18. What is the space complexity of Merge Sort? → O(n)
19. In Python, what is a generator and how is it different from a regular function? → A generator uses 'yield' to produce values lazily; a function returns all values at once

24. How does practical experience complement theoretical knowledge in the Cognizant field? → It develops judgment, skills, and the ability to handle real-world complexity
25. What is the space complexity of storing n elements in a hash table? → O(n)
26. Cognizant interviewers score candidates on 'Learning Agility.' Which candidate response best demonstrates this competency? → I once learned a new cloud platform in two weeks to save a failing project delivery
