What is the difference between MLM and formal corporate recruitment?

Recruitment fairs held by ordinary schools are relatively reliable, because ordinary units come to the school to recruit, and there is an agreement signed with the school. As long as you believe that there is no such thing as pie in the sky, it will not happen. If you mistakenly fall into the ranks of pyramid schemes, the purpose of the pyramid schemes is to lock you in after you pay a part of the fees. Regular recruitment units will not charge you fees.
