There were 3 rounds of interviews planned. The first round the interviewer asked me questions about data science, ML and some python related topics. After 1 hr of interview I got call that I have cleared that and moved to next technical interview. The problem arrives here in this round, there were lots of problem in this interview. First of all he was sitting in a very noisy environment where people were walking behind him talking and making noises. The second problem was he was not in mood to take interview and asked me only 2 questions one of which was tell me about yourself and the other questions was technical question. He left after 5 mins of 2 questions asked and said I'm done with the interview. I lost my opportunity as his "mood" was not good or something
