First, the hiring manager is responsible for your technical aspects, but I don't ask much of you. I mainly ask you the biggest challenge and solution in your previous job, and also ask you some questions that have nothing to do with your job, such as whether you are married, how is your girlfriend, and how to develop after going to Hefei.
Then hr asks you, HR-not professional at all, ask questions. Three days after the interview, I received a screenshot of the company's salary, social security and provident fund information before the first round of interview. Then a formal offer will be made a week later.
