This study analyzed the role of working alliance in individual career counseling. The level of career decision difficulties and satisfaction with life of 188 clients was assessed at the beginning and at the end of career counseling. Clients’ perceived working alliance was assessed after the third session, and their satisfaction with the intervention (SWI) was assessed at the end of the intervention. Results showed that working alliance (1) moderated the decrease of lack of career information, (2) predicted SWI, and (3) played a mediator role in the decrease of inconsistent career information. The study confirmed the importance of relational factors in career counseling, particularly of the client–counselor agreement about intervention goals and tasks.
