1. Understand the relevant laws and policies: First, you can understand the relevant laws and policies of your own region or industry and see if there are specific requirements and time limits for pre-job training. If there are clear regulations, you can follow them.
2. Contact training institutions or companies: If you find that the pre-job training is a few years late, you can contact relevant training institutions or companies in time to consult whether you can participate in follow-up training or remedial measures. If you can get a positive answer, follow the advice of the other party.
3. Consider self-study or finding a new job: If you can't attend the training or the other party doesn't provide a solution, you can consider self-study related knowledge and skills, or find a job that doesn't require pre-job training. In the process of self-study, you can learn through the internet, books, videos and so on.
