Then he further took the discussion towards operating systems, oops concepts, and programming fundamentals. This round was about 1 hr.
Round 3 (Technical Round 2): This round started with one of my projects in web development as the interviewer was also from the same background, so we had a discussion about the back end framework of the website, then he took the discussion to the code part. I was asked two coding questions.
- Sort the ages of the population, he wanted an O(n) sorting technique, I wrote counting sort for the same Counting Sort. He was satisfied with the solution.
- Unique paths in a Grid with Obstacles. I gave him the DFS solution.
Then he asked me some questions about operating systems and computer architecture concepts. This round also goes for about 1hr.
Round 4 (Managerial Round): This round was shorter than previous rounds and last about 40 mins, interviewer started with my introduction look through my resume, we had a discussion on my projects and my inclination towards web development.
