The first round was an online test. It did not contain DSA-related questions.

The second round was a technical round. I was asked to code the deletion of a node in an SLL. Going further, OS and CN questions were asked at an easy to medium level, with more CN questions.

The next round was the manager round, which lasted for half an hour. In this round, they can question you about anything in your resume, and you should know every bit about all the projects mentioned. Since one of my projects was based on an SQL database, I was questioned on how to implement payment transactions as part of DB operations. Apart from the resume, they asked one other question: how would I come up with a Sudoku solver? I answered by saying we can use graph coloring in such and such a way, but I wasn't very sure of the full implementation.

I was asked if I preferred a developer or testing role. I stated my preference for the developer role, since it was an internship.

I heard two days later through mail that I was not selected for the HR round. The offer was bagged by one candidate.

In the technical round, they asked to write code to delete a node from a linked list. Several CN questions were asked, and several OS questions were asked. Be thorough with the basics. CN questions included:

• TCP vs. UDP difference
• HTTP vs. HTTPS difference
• Types of network devices (hub, switch, and router, and their differences)

OS concepts covered the uses of an OS and how multiprocessing happens, along with some questions along similar lines.
