• Data structures basics: arrays, stacks, queues, linked lists (conceptual), binary search trees
• OS basics: process vs thread, deadlock conditions, paging vs segmentation

For GenC Next track (higher bar):

• Medium LeetCode problems: array manipulation, hashmaps, string problems, basic tree problems
• Time and space complexity analysis: expected for every coding solution
• OOP at interview depth including design patterns
• DBMS including window functions and query optimisation basics
• System design at a high level: not expected to be comprehensive for freshers

Most-reported topics at Cognizant technical interviews:

• 'Explain inheritance with an example': be ready with a clear Java/Python example
• 'Write a SQL query for Nth highest salary': DENSE_RANK or subquery approach
• 'What is a deadlock and what are the conditions for it?': Coffman conditions
• 'What is polymorphism? Give a real-world example': avoid textbook examples, use concrete ones
