Is it useful to find a relationship after a failed interview in a private school?

It's no use looking for a relationship because the interview in a private school failed. Judging from the relevant public information, the interview of teachers in private schools has a formal process, and it is unfair to its interviewers to find relationships, so it is not feasible to find relationships into the interview practice. The recruitment of teachers in all parts of the country is the responsibility of local county-level education departments in conjunction with government departments, and there are also corresponding regulatory departments.
