HARMAN interview questions

I had applied for the Product Owner position and the first round went very well. The interviewer was professional enough and knew what she was asking. The second round was scheduled on the same day and now comes the most unprofessional, unethical, and egoistic person who got offended for every answer I gave during the interview. According to him, we should not reuse the code. Throughout the interview he made me feel low. The questions asked were not rocket science. It was the typical P.O role questions. I guess I did not make it to the next round. In fact, even if they offer me, I am surely going to decline it.
