1, interview method: the investigator answers the interviewee directly.

2. Questionnaire method: the investigator printed the questionnaire in advance, distributed it to relevant personnel, and collected and analyzed it after filling it out.

3. Literature method: collecting second-hand materials such as newspapers, magazines and books.

4. Electronic media collection method: collect information through telephone, computer, radio and other media.

5. Observation method: Investigators visit the investigation site to collect dynamic information of things.

Examples of background checks:

1, HR conducts its own investigation. The advantage is that HR is familiar with the background of candidates, so it can better screen the information found, make judgments in time 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.

2. Entrust a third party to send it back to the company for unified handling. For example, all aspects are realistic, and companies like this have fixed channels for investigation information, which are more professional, neutral and objective. In China, the third-party background investigation service has just emerged, and various enterprises are mixed. Therefore, the human resources department must be careful when choosing, otherwise irresponsible perversion will not only lead to brain drain, but also bring legal risks.
