Is the recruitment of China Power Investment Corporation true?

You can tell at a glance that it is an invitation letter similar to pyramid schemes! Large groups will not send invitations directly, and it is impossible to call the hiring manager directly during the interview. It must be to save the seat number! Don't believe it! At present, I have received seven similar invitations, some of which are stamped with the company's official seal (P), and some have obvious loopholes.
