On Campus Interview After aptitude round, an Object Oriented Principles round was conducted. This has been by far my favorite round in any technical interview. They gave a question which wasn't your typical DSA based generic thing but an actual thing software developers use during their entire careers. It was a scenario which tested how much you actually understand designing (kind of like low level design) and how much fundamentals of OOP are you clear with. Your project hierarchy, is that good? SOLID principles, do you apply those? The interviewer would leave the room and join, we had to leave the screen share on. He even helped me improve my design by telling me that `Class X` shouldn't be responsible for this, buy `Class Y` should be. And in the end, I had only 2 minutes left and everything worked perfectly. Had defined proper getters/setters used a design pattern also (read Head First Design Patterns 15 days before and learnt 5-6 patterns). The focus was on how clear your code is, is it extensible to change? Do you use inheritance over composition? Cleared this round along with around 15 people. Next was a technical interview which lasted 2 hours. A male and female interviewer. They did ask some DSA stuff but nothing which couldn't be solved if you have done a little leetcode (I would say LeetCode Medium questions). Then they asked everything, from Computer Networks to Operating Systems, from Algorithms to Data Structures. Was one of the best technical rounds I have seen. Finally, a social pillar round or something where you have discussion with HR, they talk about LGBTQ and other issues in society. It is basically a culture fit round. Don't be arrogant and you should be able to clear it. Overall, great experience. Didn't end up joining as it is still a service based (but trust me, better than almost all service based companies), but memorable journey nevertheless.
