HARMAN interview questions

The overall process went smooth, but only before interview happened , the interview was scheduled online and I was asked to have a video interview. It was supposed to be of 45 mins, but to my surprise , the interview went only for 15 mins. He asked me around five questions, and I was able to answer 4 and a half, and then he concluded that he is done from his side. It was very demotivating for me, and I believe if I am even answering 50% of the questions and there is more 30 mins to go for the interview , why would you leave it without even evaluating me completely.? I had the worst experience here.

HR interview (phone) [30 min] - easy interview to understand to intention and have a more clear view of the position, Team Lead interview (phone) [30 min] - second step with some technical questions, Director interview (in person) [2 hrs] - completely technical.
