The first round was a shortlisting, multiple-choice objective test consisting of 50 questions. Half of them were general aptitude questions, while the rest were from various fields like computer programming, microprocessors, databases, and basic electronics. Around 50 candidates were shortlisted.

After that, I had 3 rounds of 1:1 interviews.

The first round was technical, consisting of various questions from linked lists, threads, semaphores, and a few basic networking questions.

The next round was mainly a resume walkthrough, where I was evaluated on my various projects and responsibilities, and my strengths and weaknesses judged.

The last round was an HR round and was more like an informal chat.

How would you code a stack using a linked list?
