SLB Software Engineer interview questions

Poor interview process, had 1 telephonic interview and 1 skype. Telephonic interviewer was ok however Skype round was worst, one hour they took to do mock call, interviewer didn't came that day, hence rescheduled the interview, again they took 30 minutes to do the setup in an 1 hour interview. I asked them to reschedule the interview but HR denied.After 30 mins interview started, he asked me java question in cpp interview, he was sarcastic and rude accross the interview, not at all the professional behaviour, then after 30 mins I reminded him about the time check, he cut the call saying this is not my problem, we started late. personally i don't recommend to be a part of such organisation. They asked to appear for further rounds, but I denied.
