Callback companies generally accept the entrustment of enterprises to make callbacks for candidates before offering, mainly to verify resume information. Generally, rotary companies will verify these resume information through various channels, mainly through inquiries.

Third-party back-adjustment companies can provide safe, objective, accurate and fair back-adjustment services. The back-transfer company has rich professional experience, and the time, manpower and material resources invested in the back-transfer service are much more comprehensive than those invested by HR and headhunters. Only callback services are provided, and services other than callback are not involved, so as to ensure the objectivity, completeness and accuracy of callback reports. So it is still relatively strict to some extent. The key depends on the degree of fraud in resume. If your resume is all fiction, then the tone behind it can be said to be very harsh. If your resume is not faked and beautified, then you don't have to worry about failing the back tone. After all, these back tones are authentic.
