What questions does the background investigation of Australian hairdressing immigrants ask?

The background check of the embassy is generally to verify your real work situation, such as: When did you join the company? What is the approximate monthly income? What is your present position? etc

According to the current background investigation of the embassy, not 100% will investigate.

Your boss has two branches, and the embassy will generally investigate directly at the address shown in the documents you submit. In case you are not in the store, the answers given by colleagues or bosses will affect the visa officer's judgment on your application. If the answer is outrageous and completely different from the materials you submitted, it will definitely have an impact.
