This is not normal. The examinations of general institutions must be completed by written examination, qualification examination, interview and physical examination. If the recruitment conditions are vague and there is no need for qualification examination, I think you can give it a try and maybe you will succeed. Although everyone says that the examination of public institutions is opaque, if it has been fixed, why not write the recruitment conditions according to the fixed qualifications? Maybe the recruiting unit is eager to recruit people and wants to ensure the quality of the people who enter.
