Arista interview questions

As a new graduate position. The first round was general questions, easy. The interviewer was friendly and lovely. In the second round, they will match you with someone. I am good at cloud. But the process experience was not good. The interviewer is from Extensible Operating System, and all the questions are about the operating system, old and basses . No one ever told you this, my field is not that. He didn't take anything from your resume. He asked all the questions about the operating system. I don't know why for a new grad job all the questions are not based on the person's field and experience even though they say they will match you with good one. It's a horrible experience for new graduates.
