In both cases, pre-employment training can be unpaid, because it is not an on-the-job employee and has no formal employment. It is illegal to sign a labor contract, formally enter the job and conduct unpaid training.

Mainly depends on whether the pre-job training is within the contract period. If it is within the contract period (including the probation period), the salary will be paid; If it is not within the contract period, the employer may not pay wages. Because the employer pays wages on the premise of the existence of labor relations, if there is no labor relations, the employer can not pay, of course, but also pay (because the law does not prohibit such voluntary payment)
