Despite the well-recognized importance of career maturity in job searching, little research has been done on the influence of career maturity on job attainment. Drawing on the extant literature, this study examined the relationship between career maturity and job attainment, and explored the boundary conditions that maximize this relationship. Data were collected from 1,202 young people during two time periods in Hong Kong, China. The results showed that career maturity was positively related to job attainment, and that both emotional intelligence and social vocational interest amplified the positive relationship between career maturity and job attainment.
