Here’s the revised version with grammar and clarity improvements:
I attended the interview, but the interviewers were not friendly and only talked about their company. Then, they asked me about work I did five years ago, which I found unacceptable. I offered to show them my recent work instead. It was clear they didn’t understand the structure of UX and UI, nor did they know the difference between mockups and high-fidelity designs. They were very rude and mentioned they were looking for B2B screens.
