Yes Examination is an important link in the recruitment of railway bureaus. Passing the exam can help employers better screen out talents. The examination questions of the railway bureau usually cover the necessary knowledge and skills in the work, and also have certain requirements for the ability and quality of candidates. In order to reflect fairness and justice, the railway bureau also needs to carry out some pre-test training, including providing teaching materials and examination guidance, to ensure that all candidates can show themselves in a fair examination environment and get a fair evaluation.
