It was an oncampus interview, they shortlisted 2 candidates after first technical interview. Both of us had another technical interview followed by an HR round/director round. All my interviews went well, I answered everything they asked me. In the HR round, the only thing they asked me was my intro, following which, the director explained what the company did and asked me which team would I like to join. After interview, I was told that I'm kept on waitlist and the other person had been selected, who had very bad interviews compared to me, he could not answer what he was asked.
