Applied online. Then a phone screening from a recruiter. Then a zoom interview with the hiring manager. I have to say this hiring manager has an anger issue. We didn't communicate well at one point. Then he became angry and kept saying " I've told you before, why you said this, again and again, I mean the business problem, not the technical definition". And he said I didn't think you have built models before. And I tried to explain to him, he didn't listen, he interrupt me again and again. How can you communicate well with a person who doesn't listen to you ??? I'm disappointed about this interview. It ruined my day. In my last 5 years of career, I have never encountered someone who is so UNPROFESSIONAL as him.
