Interviewer thought himself of some sort of big shot in the design industry, it was more about boasting how good and talented his team is, how I am not fit enough to join the team, I was asked to solve a design problem, but all he could do was find faults in the problem and not even appreciation, it was like he decided because I am from engineering background I am not fit from the beginning. Has to be the worst interviewer and the interview in my life.
