Nacre Capital interview questions

Firstly, the hiring manager didn't let me finish one complete sentence. He was rude and not letting me finish almost any word Our call duration was about 10 minutes, and he didn't ask me any reliable question, he started up by saying: "I'm very busy, let's do it fast." The last question was "What is your salary expectations", and I answered "8k USD", and he said: "Ok too expensive, bye" Even though I tried to say: "I'm opened to a negotiation" He just hanged up in my face. Tottaly unnecessary and rude.
