Infosys Systems Engineer interview questions

After my introduction, the interviewer asked some CS Fundamentals questions: OOPs and its four pillars(with examples), SDLC in Agile Software Development and Deadlock in Operating Systems. Then he asked where had I recently applied my Web Development skills(that were mentioned on the resume) so I told about the hackathon held the previous week where I used them, I also mentioned learning a completely new tool Motia with just the documents and resources the hackathon organisers provided to make the submission project. Then he asked their versions I worked on(HTML, Python and so on) and I said that I did not remember the exact versions. Following this, he asked to explain the Blockchain in layman language since my both projects were made with it and how it was used in project and its significance. I answered all correctly. Then he asked about why I choose blockchain. At the end, he looked at my submitted essay of the OA and asked questions from it which was about merits and demerits of social media.
