IBM Software Developer interview questions

Standard hacker rank interview with 2 questions based on leetcode style questions. Got 2 medium questions. Make sure to brush up on data structures and algorithms as well as object oriented programming.

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.
