Civil servant interviews can't go through the back door. Going through the back door is equivalent to cheating. Once the consequences are found to be serious and fair, all aspects of the exam are very strict, especially the interview. The interview process is very rigorous, just to avoid the possibility of cheating.
In the interview process, candidates don't know which examination room they are or who their interviewer is before the interview, but the interviewer draws lots temporarily on the day of the interview, which is random, so candidates can't know who their interviewer is, nor can they know their examination room and test number, and the interviewer doesn't know the candidates' information of this examination room before the interview.
So it is impossible for both parties to know the relevant information of the interview in advance. Candidates cannot reveal their basic information during the interview. Once you tell your personal information, you will be considered cheating and disqualified from the interview. So the interview can't go through the back door, and there is no way to go through the back door.
The organizers of national civil servants are the Ministry of Personnel and relevant ministries and commissions, and local civil servants, whether provincial capitals or prefecture-level cities, are recruited by the Provincial Personnel Department. Most people's so-called "relationship" is a small section chief and director of a county or city, but how big his instinct can be, people who pass the exam by abnormal means must have it.
