First, there was an online test which consisted of MCQ questions on aptitude and CS basics. Then there was one technical interview round, and finally, shortlisted candidates went through one HR interview round.

The first round was a technical round where I was asked about stacks, queues, linked lists, databases, operating systems, and other parameters were covered. The second round was a managerial round.

The interview began with introductions, followed by questions about my projects. Then, core OOP concepts were discussed. I was given a coding question on hashing: checking if all elements of Set 1 exist in Set 2.
