Within the establishment of China Life Group Insurance

In fact, this back office job you mentioned is not a back office post in the establishment of China Life Insurance. You signed an agency contract, not a labor contract. In fact, this back office is to recruit people, that is, to keep making recruitment calls and inviting people for interviews. The more people you recruit, the higher your salary will be.

It's the account manager of China Life Insurance who interviewed you. The interview process is not a formal HR interview process, but more about what the future development will be like. Personally, if you have a strong resistance to the insurance industry, don't go.

It's hard to get back-office jobs in China Life.
