For the position of labor dispatch, is it the labor service company or the work company that interviewed?

Generally, the company is interviewed directly in the workplace. If the post has special requirements, the labor service company can conduct an interview in advance. It is mainly a company interview for on-site work, and subsequent employment can only be arranged after the interview is passed. Of course, the contract was signed with the labor service company. Personal interests have nothing to do with the company's on-site work.
