This article examines the relationship of career indecision, job search behavior, and employment among college seniors based on sub-scales of career indecision (lack of career information, lack of self-clarity, decisiveness, lack of necessity recognition, external Barrier). This study explored the effect of career indecision, job search behavior, and employment successes(number of application, number of interview, number of job offer) in longitudinal method. In result, career indecision had negative effect on job search behavior. In other words, the higher career indecision level is, the less job search behavior is performed. Especially, career indecision is connected with preparatory job search behavior and informal job search behavior. Another finding is that job search behavior in time 1 (first semester of college senior) had a strong effect on all of employment success variables in time 2(second semester of college senior). Finally, the theoretical and practical implications of this research were discussed. Based on the limitation of this study, several directions for future research were also suggested.
