HP Inc. Data Scientist interview questions

An initial telephonic screening round was scheduled. It did not happen and I got a call from the consultant HR that there would be direct face-to-face technical rounds - 2 rounds during the same day. I reached the venue well in advance on the day of the f2f round. However, the interviewer turned up 2 hours late. Not even a simple apology. His attitude during the entire interview was that of a king answering to a beggar. He did not introduce himself, let alone explaining what work his team does. Not very knowledgeable as can be expected out of people with such demeanour. At the end of the interview, he said that it was an initial screening round and I would later be told the schedule of the next round. Needless to say, I was happy that I was free to leave and never enter this company's premise again!
