Lingyun was recruited by the Employment Bureau in the second half of last year. It seems that the target of recruitment is fresh graduates, with a college diploma and mechanical major, but only contract workers. It is said that after studying for a month, I will go to Wuhan for an exam. Those who pass the exam will be hired, and those who fail will click.
Another recruitment platform is the school. Many graduates from aviation colleges in other provinces are recruited through the campus.
You can go to the post bar and ask, there are some friends who work in Lingyun, they may know more information.
