Why is it that the recruitment of Suzhou Yuancai clearly stated that it needs 30 operators, but the total number of people we went to the factory for an interview was only 20, and only 3 people were recruited? Is it? ... I'm Yuan Cai who led the interview with Nokia. There was a big gap in their continuous recruitment in May. It's not that they don't recruit much, but that they are demanding and must have relevant work experience, so there are many people who often go and few people apply. . . . . . I'm used to ╮ (╯ ▽ ╰) ╭ You see?
