What system does the hospital use to recruit newly graduated medical students as formal doctors through normal channels? Is there a qualification examination?

Generally speaking, if you want to go to a regular hospital, you must first go through an interview with the hospital, and then take a written test. Depending on the hospital, some will take additional tests. After you pass the test, you will sign a tripartite agreement and submit it to the school. recommendation form and sign the final employment contract in the early stages of work.

I think you are talking about the occupational physician qualification examination. This is the most basic if you want to be a doctor, otherwise it is illegal practice.
