How does the National Security Agency recruit civil servants? How to recruit internally?

The conditions for applying for the National Security Bureau are mainly the conditions put forward by the National Security Bureau that year.

I would like to remind all candidates that the recruitment conditions of the same position in the same department may change every year. For example, last year, the professional requirement of the Security Bureau may be the police academy, and this year it may become an accounting major. Therefore, it depends on the job requirements issued by the national civil service examination in that year, and you can't register at will.

Note: when candidates apply for civil servants, remember that they can only apply for the position if they meet all the requirements of the position.
