There are many large companies that hire workers on a seasonal basis. Resorts and hotels are in this group. When the season is about to begin, they often need new employees to replace those that have gone on to find year-round employment. Rather than hold interviews at their hotel or resort, they hold work fairs and exhibitions. Some of these exhibitions feature multiple companies. This makes it a good place for a person seeking employment to look for work.
Hotels, resorts and even cruise ship lines often open new facilities. When this occurs, they need to hire and train many workers at the same time. Employment exhibitions help them quickly gather applications, resumes and interviews of a great number of people in one location. It gives the company a chance to show the advantages of being employed with them. It also offers a chance to meet many prospective candidates available for immediate employment and training.
