Do laborers need to make an offer when they join the company?

when large enterprises hire laborers, they will offer you an offer. First, they will call you to inform you that you have been hired, and then they will offer you an offer. Then they will ask you to prepare materials and sign a contract after you join the company.

If the so-called offer issued by the company has neither salary nor job title, it is likely that the so-called offer you received is not a formal offer, but a recruitment intention or oral notice, which does not count from the legal point of view and cannot be regarded as a formal contract signing offer.
