HR was polite

During the pandemic, the interview was conducted online. The interview had been scheduled in advance, and the HR representative and supervisor attended together. The HR representative was very professional, but the female supervisor was very impolite. Throughout the interview, she kept handling her own things, and after asking questions, she even responded sarcastically to the answers, which was truly astonishing. This made the atmosphere of the entire interview very unpleasant, and I just wanted it to end as soon as possible. After the interview, I could already guess that there would be no follow-up, but HR said they would provide a response within 8–10 days, and then disappeared into the crowd. Speechless once again.
