Recently, I received some job calls. How do I know if they are cheating?

This is very simple. First of all, when you put your resume in the talent market, you should make a record yourself. After that, once an applicant company calls you for a second interview, you can ask the name and address of that company and check the record of your investment. Now some large enterprises have some online publicity, such as websites, you can check them out. Be careful to make it last forever.
