Be careful, if you believe the authenticity of this job, you must sign a labor contract before you can pay the training fee. Regular units, even if they need to pay training fees, can only collect them after they become employees, and most of them use the method of deducting money from employees' wages in batches, and will not require employees to pay them in one lump sum. If you don't sign the contract, I want you to pay, so be careful not to be cheated.
