Generally, the head office has the final say. Most of those who can get formal establishment are through the recruitment examination held by the head office, and they will be allocated after passing the examination.
In bank recruitment, there are three main forms of employment: formal workers, targeted recruitment, and labor dispatch, but they are mainly divided into regular workers and dispatched workers.
It is true that bank wages and benefits are good, but normally, dispatch workers may not be able to enjoy the benefits that regular workers can enjoy. Therefore, when applying for the exam, try to choose a formal employee establishment that can sign a labor contract. If you have already become a dispatched employee, then hurry up and become a regular employee!
