I applied in the career portal, and HR contacted me and scheduled a technical discussion (3 rounds). It was a self-introduction followed by C/data structure questions and questions from my resume/work background.

Prepare basic C/data structure questions rather than complex algorithms, and be prepared for what you've mentioned in your resume.

1. Convert decimal to binary using recursion.
2. Factorial using recursion.
3. Linked list: check palindrome.
4. Find palindrome in substring.
5. Minimum element in a rotated sorted array.
6. Print pattern (reverse pyramid).
7. Mod operation without using the mod operator.
8. Addition without using '+' .
9. Replace every element of the array with the greatest element on its right.
10. Array of integers: find three integers a, b, c where a + b = c.
11. Sort [1,0,2,0,2,1] => [0,0,1,1,2,2].
12. Print transpose of a matrix.
