First, the human resources department conducts its own investigation. The advantage is that the human resources department is familiar with the candidate's background, so it can better screen the information of the survey to make judgments and save costs. The disadvantage is that individualism is strong and the investigation may not be objective and rigorous enough. Because the investigation skills are not professional enough, it is easy to waste recruitment costs and energy. Another situation is that if the candidate is poached from a competitor, the former employer will inevitably have resistance, and the human resources department may create a more embarrassing situation when contacting the former employer.

Second, entrust a third-party rotary company to handle it uniformly. For example, a company like this has a fixed investigation information channel, which is professional, neutral and objective. In China, the third-party callback service has just emerged, and various enterprises are mixed. Therefore, the human resources department must be careful when choosing, otherwise irresponsible callback will not only lead to brain drain, but also bring legal risks.

Third, let headhunting companies conduct background checks. This practice saves energy and cost, but some headhunters usually do some "technical processing" for candidates because it is in line with their interests.

At present, most enterprises outsource the background investigation of the whole company to a third-party professional company. For them, choosing a third-party company is a good choice, because they have more employees and the budget is just enough. Even so, the human resources department should be familiar with the whole background investigation process and related technologies to facilitate the supervision of third-party companies. It should be noted that if the third-party post-adjustment company finds negative information, the employer may ask the third-party post-adjustment company to conduct a second investigation. If necessary, you can also participate in the investigation in person.
