It was an on campus offer, the interview was one of my first experiences of an interview. I was not initially shortlisted but then somehow called the day itself with a 2 hours of gap. Thus I really was underprepared. The usual chit chat happened, the interviewer looked at my resume, and asked questions. I was able to answer few and not others as i was not that prepared. Then some behavorial interview questions were asked and I was let go. Pretty standard interview i would say but my lack of preparedness was the reason to not advance to further rounds.
