Does the examination interview of public institutions depend on relationships?

In fact, I think some people may have passed the exam, but it doesn't mean that they can't pass the exam if it doesn't matter, because now they have to pass the written test and interview to get a job. Many related people can't get into the interview because of their poor written test results. How do they find jobs? Besides, interviews are now structured interviews. Examiners are composed of personnel departments and recruitment units, and are grouped by lottery on the spot. And it is not easy to cheat.
