There are three main methods for placing job advertisements related to mid-career recruitment: “open recruitment,” “mediation,” and “others.” “Public recruitment” is divided into the Internet, job information magazines, newspaper advertisements, newspaper inserts, etc., and it can be said that it is the most common method, but each seems to have advantages and disadvantages. There are a wide variety of job sites on the Internet, and they are characterized by being composed mainly of text and photos. It is the most major job advertisement at this stage, and it has the advantage that it can be used by many people regardless of the time or place to read it. On the other hand, it is difficult for people to find the Internet unless they access it voluntarily. Job information magazines located near the entrances of convenience stores and supermarkets are easy to read, so they are easy to use regardless of age, but the disadvantage is that the information is limited to regions. In addition, while newspaper advertisements can cover a wide area with one advertisement, the advertisement fee is high and it is difficult to design the magazine.
