I prepared very hard for the role, but the interviewer did not ask me even one single thing about the subject matter. They were only interested in my CV, my internships, my family, my projects, etc. The interview went smoothly like a conversation, and was pretty easy. As a fresher, they didn't expect me to know too much other than my CV and that is what the interview revolved around. Two weird things that happened were that: 1. It was an online interview, and the interviewer did not have their camera on for even a microsecond. 2. They asked me if I had any plans for Marriage, as they expected me to work late nights and longer hours.
