The company's contract for interviewing mold workers is really about manufacturing. Is this contract valid?

The validity of the contract mainly depends on whether it conforms to the law and whether both parties are willing. As long as the terms in the contract do not violate the law, and both parties voluntarily sign it with full knowledge of the contents of the contract, then the contract is valid. In the recruitment process, it is necessary to ensure that the core employment information such as position, work nature and work place is consistent.

If there is any inconsistency, you can question it. Generally speaking, as long as both parties reach an agreement and the contents of the contract are legal, the validity of the contract can be confirmed.
