First round was standard - general programming language related questions and one problem. Interviewer was polite and had a good experience. Had second round with a senior member (20+ years exp). It was the most uncomfortable i have felt interviewing in a long time. He was constantly interrupting, not even allowing 20 seconds for an answer. It was affecting my chain of thought, and my general confidence level. In the end, he asked to write a basic http server that accepts a json request and stores in memory, which i did. I don't know what was the point of that if he had already made up his mind.
