What does "outsourcing" mean on the recruitment website?

Outsourcing can be the outsourcing of recruitment, interview, insurance and other personnel work to other companies, that is, workers sign contracts with employers. If it is dispatch, it means that you sign a labor contract with the dispatch company and then send it to other companies to work ~

Of course, the advantages of outsourcing are convenience, cross-border and reducing the cost of employing people.
