What is the content of the written recruitment test for urban rail transit companies?

Rail transit companies (commonly known as subway companies) generally have two kinds of recruitment, one is school recruitment and the other is social recruitment. School recruitment is divided into spring and autumn, and the rail transit company will send people to relevant schools (both undergraduate and junior colleges, generally offering rail transit-related majors, which are basically established railway schools) to hold presentations, conduct on-site interviews, and sign tripartite agreements if they pass the interviews. Generally, school recruitment is not tested, because under the same conditions, the school recruitment of the railway bureau is not tested, and the treatment of the railway bureau is better than that of the subway in all aspects. Therefore, the subway school recruitment has no advantage in the old railway colleges, and it is often a leak. The other is social recruitment. Most social recruitment requires exams. The content of the exam is generally similar to that of the civil service exam. A few may examine professional knowledge and ability, but they are all relatively simple. Everyone goes to the workers' post, and promotion is slower than school recruitment. Social recruitment is actually a supplement to school recruitment. Some subway companies do, and some subways do not conduct social recruitment. So, they have to think it over.
