Few companies have trained for so long. Some companies are doing regular work in the name of training during this period, but they pay trainees' wages, which can save a lot of wages. If you can't stand it during the period, you can resign at any time. Anyway, it is very beneficial to the enterprise.
So you have to ask clearly whether it is training or after training, how to calculate the salary, what is the difference between the work content and commuting time during the training period and the regular workers, and how to calculate the insurance and all aspects of protection.
