BNP Paribas Senior Java Developer interview questions

They called for face to face for last round with VP and experience was worst ,it was virtual still they called office and made me wait for 1 hour and then the person who took interview was quite busy and not interested and gave negative feedback even after clearing all rounds

Instead of interviewing with he get into argument, what sort of behaviour is this. I won't recommend the company. These guys provide hacker rank assignment, if you solve hacker rank next round they will ask how you solved hacker rank question and they will evaluate there. Interviewer only doesn't know many things he interviewed me and got into argument.
