How to do employee background check?

The background investigation methods of large companies are as follows:

First, prepare ringback tone data. Generally, the recruiter will reverse your past before determining the offer. If you are a basic person, or a manager, you will generally reverse the previous company. If you are a manager or above, you can turn the last two companies upside down. The reverse adjustment is not the number of companies, but the real situation.

Second, according to the ringtone you provided. The recruiter is only dubious about the credibility of this back tone. If the comments of the back tone are all good and bad, the credibility of this back tone is basically not high. So the phone number you provided is not credible, which will only lead us to make other ways to reverse the tone.

Third, the interviewer speaks for himself. This is the highlight, and this back tone is absolutely correct.
