HARMAN interview questions

I got a mail from HR to attend interview on next day itself in Bangalore location. I reached to office at 11.30 though they asked me to come at 12. Very few interview panel and they had called many candidates. My interview started at 3.45 and just want to mention that interviewer was such an illiterate person. First he took 6-7 minutes to decide the question(reverse an array without affecting special characters) what he wanted to ask. then somehow i solved that but he did not agree with my solution and argued. Next he ask 2 theory question such as serialization and abstraction and he told me to leave for the day. He didnt even ask for 5 mins and asked me to leave for the day. I wish i would have asked him some question and came , it seems like he was sleepy and out of questions. They should respect others time as well, just for 5 mins of interview i wasted my whole day.
