The standard of the back adjustment lamp is mainly decided by the employer before cooperating with the third party back adjustment company, and the standards of each company may be different. Specifically, the standard of back modulation is usually divided into the following types:

1. Green light: indicates that there is no anomaly in the verification range and the verification passes. This usually means that the candidate's background information, work history, education, criminal record, etc. are consistent with the information provided by the candidate, and no untrue or potentially risky information has been found.

2. Blue light: indicates that there is a hint or small difference in the scope of verification involved. In this case, whether the result of the back adjustment is passed depends on the final choice of the employer.

3. Yellow light: indicates potential risks in the scope of verification, project verification has not been completed, or the project cannot be verified. The situation of yellow light is relatively serious, but whether it is passed by the back tone is still decided by the enterprise. For example, if the candidate has an average relationship with a past leader, the leader may viciously retaliate or exaggerate his or her problems, in which case the backtone may light up in yellow. However, as long as the candidate actively communicates with HR and explains the context, it is still possible to pass the back tone.

4. Red light: indicates that there is a very high risk or untrue information item in the scope of the verification. A red light is the most serious condition, and it usually won't pass. Situations that trigger a red light may include: mismatched work history or education, negative job performance, criminal record or illegal behavior, credit history or financial problems, false personal background information, etc.

In general, the standard of back modulation is determined by the employer, but the specific judgment results will also be affected by the actual situation of the candidate, the back modulation ability of the third party back modulation company and the recruitment needs of the employer.
