Is the recruitment information of PCB on pcb8 18 talent network deceptive?

Recruitment information of many websites may appear, so candidates must inquire about the background, registration information, office address and venue of this enterprise. If the address is only an office building and the headquarters has no independent office location, it is likely to be a small startup company or a leather bag company. It is conceivable that there are training institutions that pay training packages for employment. This is on many large websites, and no one is in charge at present.
