IBM Software Developer interview questions

First round was technical screening with basic oops questions, second round was coding with 3 questions and it involved debugging as well since the role was for production support and third was with 3 interviewers regarding domain knowledge and cv and 4th was in person interview regarding my cv and experience, and there was no proper communication from the team, i was called around before day afternoon to attend a in person interview on next day and the interviewer was so rude.
