Career preparation is not full-time, you can write a college degree. Because the career establishment of civil servants or some positions require full-time students to take the exam, the so-called full-time is the diploma that students graduate from the college entrance examination, and the on-the-job education is the secondary school and junior college or undergraduate education after work.
Basically, there are work restrictions. For example, there is a full-time undergraduate degree or above in the remarks column behind a position (this is the most common requirement of recruitment agencies). If there is a junior college degree or above and full-time is not indicated, you can apply for this position, but the competition is more intense. This position is often 100 people.
