What's the difference between on-the-job graduate students and full-time graduate students? What's the difference between job recruitment? Are they the same level?

This is not a concept. For example, in some enterprises that require high professional knowledge and skills, on-the-job graduate students can't meet the requirements, while full-time graduate students have certain talents and practical learning because of their long learning cycle. However, some institutions only look at diplomas, and there is not much difference between on-the-job graduate students and full-time students. This is why some leading cadres are doctors or masters, and they are generally on the job!
