Does the general job fair sign the contract on site?

I can't sign the contract at the on-site job fair for the following reasons:

1 The personnel sent by the enterprise to attend the job fair generally include HR and business manager, and the on-site interview needs to be taken back for feedback and discussion.

2 interview process generally speaking, it is impossible to interview once. This situation only exists when the boss personally recruits.

Signing an agreement is a contractual act, which regulates the interests and obligations of both parties. There is no guarantee that the contract will be signed immediately after the interview.

Practice is the only way to test your understanding. Ask questioners to attend many job fairs, and ask whether the employees of each enterprise have brought paper contracts.

The phenomenon of "oral offer" cannot be ruled out. This kind of situation exists objectively in normal economic life, but it still needs to be implemented in a paper contract to be a real signing.
