1. If you make fraud in your resume, in this case, if the fraud is not serious, you just optimize your resume appropriately. You can communicate with HR in time, admit your mistake, ask for forgiveness, honestly describe your advantages to HR again, see if there is room for change, or have another interview. If you deliberately make a large-scale deep fraud with luck, then you must first reflect on your integrity and find the next job.

2. If you don't know why you can't get an answer. At this time, you should contact HR immediately, feed back the ring-back tone results and ask the specific reasons for not passing. Ask for a chance to readjust, or explain why the callback failed. The core of background investigation is truth, and everything contrary to truth is the reason for the failure of back tone. Investment is risky, please make a careful decision.
