3) trade fairs -
A trade fair is an exhibition organized so that companies in a specific industry can showcase and demonstrate their latest products, service, study activities of rivals and examine recent market trends and opportunities. In contrast to consumer fairs, only some trade fairs are open to the public, while others can only be attended by company representatives and members of the press therefore trade shows are classified as either "Public" or "Trade Only". A few fairs are hybrids of the two; one example is the Frankfurt Book Fair which is trade-only for its first three days and open to the general public on its final two days. They are held on a continuing basis in virtually all markets and normally attract companies from around the globe. For example, in the U.S. there are currently over 10,000 trade shows held every year, and several online directories have been established to help organizers, attendees, and marketers identify appropriate events.
4) job advertisement -
Advertisements are the most common form of external recruitment. They can be found in many places (local and national newspapers, notice boards, recruitment fairs) and should include some important information relating to the job (job title, pay package, location, job description, how to apply-either by CV or application form). Where a business chooses to advertise will depend on the cost of advertising and the coverage needed (i.e. how far away people will consider applying for the job.
