It was a campus interview. The first round consisted of technical aptitude, with 30 questions in 30 minutes. It was very much doable. The questions were based on C outputs, Data Structures and algorithms (time complexities), DBMS SQL, one or two math problems, maybe regular expressions, Java, and all core subjects.

There were then three technical rounds. There was no HR round; mostly the third technical round included HR questions.

Array rotation (Left shift an array k number of times, such that the elements moved to the left after reaching the end should again come at the other end).

Reverse the first k elements of a Linked List.

Given an array of elements, find the minimum absolute difference from the array (difference between any two elements, return the minimum one).
