Current industry requires a change of hiring system on competitive advantages and there has been growing interest in the degree to which human resource systems improve to organizational effectiveness. This study aims to examine the hiring system and characteristics of human resources in Korean advertising industry. For our purpose, we explore the change of labor market for the last 10-years and then compare the difference between person-job and person-organization fit as selection criteria of new employees. Data was collected from industrial statistics of the 'Ad Directory' from 1999 to 2008, and a survey was conducted with 131 supervisors working advertising-related companies. Results indicate that the average number of employees was approximately 19,000 for the last 10-years and recently has been exceeded 20,000 people in the whole advertising industry. From the trend of labor market in advertising industry, we predict that the demand for new employees will be more increased in the advertiser and media companies than in the advertising agency at the future industry. Also, our results show that companies prefer the person-job fit to the person-organization fit in selecting advertising professionals, except that advertisers consider both criteria of fitting person-job and person-organization. Finally, we discuss some implications and limitations of this study.
