I was in Chengdu and received a call from Guangdong saying that it was from Shell’s recruitment department. Is this reliable?

Liar

As long as you firmly believe that pie is impossible to lose in this world, you will not be deceived. If he calls again, he can say anything, but he cannot reveal his personal information or pay any fees. Just play with him. You don't have to spend money anyway, and you can also increase the cost of the other party's phone calls. Haha, just treat it as entertainment.
