Three processes, self introduction, behavior question, question you have to them. It around 30-60 minutes. The process is normal but interviewer is unprofessional and rude have bad experience with them

I went to an interview where the interviewer is yawning and asking a lot of confusing questions. Very unprofessional and unprepared. After the interview, I understood that the Engineering department does not align well with each other and is consistently having conflicts.
