LuLu Hypermarkets interview questions

It was suppose to be 3 rounds of Interview 1. Coding Round 2. System Design 3. Interview with CTO. The coding questions were fair. 60 mins 2 questions but there was no proctoring. A guy used his phone and wrote while others were still dedicated to write there own solution. I cleared the round, but the interviewer was irritated soul he was rude, how did they gave chance to you as fresher to work in Banking. Why did you work on frontend. I should have stayed on Backend. He didnt listened anything just said ok bye. He just wanted to get rid of the interview somehow. Atleast HR Steve was polite he said sorry for his behaviour.
