Dr. Reddy's Data Architect interview questions

Worst interview I ever had. Interviewer doesn't have any professional behavior, very rude. He was sticking to his version of answers and wanted to answer the same. Mocking while answering. And was rushing to next question when I am answering his previous one. Total waste of time and good that I have been rejected, so that I won't have to work with such a pshycopath teammate
