In terms of machinery manufacturing, which is better, the university order class or the job fair? What are the advantages and disadvantages of each?

Order class is better. The advantages of the order class are: first, during the school period, the order unit provides internship opportunities, and the course knowledge is closely combined with practice; Second, you can find a job after graduation. But the order class also has disadvantages. It is mainly the unit that must sign a contract for employment, and lost the opportunity to find a job in a better unit. If the unit fails to order, it will pay liquidated damages. If it's just a job fair, that person doesn't think you need to stay! There are many job fairs, although there are relatively many jobs in campus job fairs, but all of them are attended by a bunch of college students, and the level has naturally improved a lot;

Look at the reason why you left early. I also graduated from college. At that time, I didn't know I could leave early, so I wasted half a year in college and just muddled along like that every day! I have always felt that it is more meaningful to come out to work in advance than to stay in school, mainly because of professional problems. See whether your professional work needs to focus on skills or experience. If it is the latter, it is also a good thing to come out early!
