Acumen Diagnostic interview questions

It was more of a desperate need of employees rather than an interview to be honest was just going through the formal process but didn’t feel like questions matter to anyone

I reached the place well before the CEO does, and to my surprise, the atmosphere is very tense and everyone in the office looked stressed out. When the CEO arrived looking like she was in a very bad mood, she asked me to go in her office for the interview. First question is to introduce myself, which I did, but she cuts me off about 10 seconds later with another question. She then started to criticise me out of nowhere. She asked about my grades, which she said was decent, but she preferred to hire people who are "more educated". The whole interview lasted for just 5mins, and I felt very disrespected. Please be more polite to people.
