Background check refers to the act of verifying the personal information of job seekers by collecting information from external job seekers or previous employers. It is an effective method to directly prove the situation of job seekers. Background checks can be conducted either before or after the in-depth interview. This will take some time and financial resources, but it is generally still worth doing.

背景调查的做法通常有三种：

There are usually three methods for conducting background checks:

1）推荐候选人之前，做好背景调查，将背调报告和候选人推荐报告一起发给企业。这是更的方式，也是更难的。国内的候选人还没有养成这样的职业习惯。

1) Before recommending candidates, conduct a background check and send both the background investigation report and the candidate recommendation report to the enterprise. This is the most professional and difficult way. Domestic candidates have not yet developed such professional habits.

2）候选人接受Offer，提出离职之后，做完背景调查。这时候的候选人去向已定，比较容易获得更多的背调对象。

2) After accepting the offer and proposing to resign, the candidate completes a background check. At this point, the candidate's destination has been determined, making it easier to obtain more candidates for backtracking.

3）候选人入职后，表现和实际情况不符，需要做更深入的背调。

3) After the candidate joins the position, their performance does not match the actual situation, and they need to conduct more in-depth background checks.

如果是猎头顾问做的背景调查更好在候选人上班之前做完；如果是企业自己做的，更好在候选人保证期结束之前做完。

If it is a background check conducted by a headhunting consultant, it is best to complete it before the candidate goes to work; If it is done by the company itself, it is best to complete it before the end of the candidate's guarantee period.

因此猎头对于背调还是应当慎重的，一份详尽的背调不仅是对企业的负责，也是对猎头顾问生涯的负责，像那些猎头公司排名的企业中的顾问，他们是非常看重背调的。一旦发现被调查对象有重大问题，都会及时反馈给企业，有时甚至会放弃服务费，因为很多东西，尤其是在行业中的信誉并不是可以带来的。

Therefore, headhunters should be cautious when it comes to backtracking. A detailed backtracking is not only responsible for the company, but also for the career of headhunting consultants. Like consultants in leading companies in headhunting, they place great importance on backtracking. Once significant issues are found with the surveyed subjects, they will promptly provide feedback to the enterprise, and sometimes even give up service fees, because many things, especially reputation in the industry, cannot be brought about by money.
