The service standard of internal and external office management of a bank, if it is a management trainee, is not a post, but represents a project. This concept originally came from foreign companies, mainly recruiting fresh graduates, with the goal of "cultivating future leaders of the company". Generally speaking, the job content is not fixed, which requires a period of training and job rotation, and finally posts are fixed. In the early stage of management training in any enterprise, we should start from the basic position.
