The first round was aptitude and technical questions related to algorithms, operating systems, and network systems. You needed to clear all sections with some minimum criteria.

Once you cleared this, you would have three technical interviews and one HR interview.

The selection process could be defined as luck because it is based on the panels you are going to get interviewed. Even if you speak and discuss well, they may reject you. It is all dependent on your interviewer's point of view. It would be a bit of a tiring process because you would not be given much time between the interviews.

Concepts covered include linked list basics, operating system fundamentals, and writing test cases for semaphores, starvation, file system operations, and more.

I am quite confident that even the technical reviewers may not be familiar with how to write test cases for these concepts.

Puzzles, all sourced from GeeksforGeeks, would also be asked.
