First, the pre-training understands that job seekers have the right to choose. Pre-employment training can let job seekers know the specific content of the job and the company's culture and welfare benefits. At this point, employees have the right to choose whether to join the company. When they feel that they don't want to join the job after three days of training, it doesn't matter to tell the referee, and they can choose not to join the job.
Second, if you don't go through the immigration formalities, there won't be too many formalities. I don't know that I don't need to go through the entry formalities before training, just tell the referees the reasons for not joining or not wanting to join. The initiative to join the job is in the hands of employees.
Third, if you go through the entry formalities, you need to go through the resignation formalities in accordance with the contract. If you have signed the entry procedures before the training, you need to go through the resignation procedures according to the contract. Every company has different procedures for leaving, but it may take some time and procedures, which is more troublesome.
The above is my personal opinion. In fact, before joining a company, we need to know something about it. In addition to the position and company, we should also consider whether we really want to do this job, which will also affect our daily mood and emotions. If we really don't want to do a job, don't force ourselves. We should choose a suitable job in time.
