Career interventions with unemployed populations benefit from mixed-methods approaches, as they allow capturing both objective outcomes and participants' and psychologists' subjective perceptions. This study aimed to evaluate a structured group career intervention, delivered both face-to-face and online, grounded in Social Cognitive Career Theory and the Multidimensional Employability Model, and designed for unemployed adults. Two complementary studies were conducted. The first examined the longitudinal effects of the intervention on employability resources — human capital and career development, social capital and networking, career identity and self-management, and environmental monitoring — with 212 unemployed adults: 85 in the face-to-face group, 58 in the online group, and 69 in the control group, assessed at three time points (pre-test, post-test, and follow-up). The second study explored the intervention process with 153 participants of the program and 18 psychologists who facilitated its delivery, using a qualitative design that combined descriptive statistics from quantitative data with content analysis of written reports. Latent Growth Modeling revealed sustained improvements in participants' employability resources, highlighting the positive impact of the program in both modalities. The process evaluation identified facilitating factors, perceived obstacles, and strategies used to transfer acquired knowledge and skills to real-life contexts. Together, these findings underscore the importance of integrating outcome and process evaluations to achieve a comprehensive understanding of career interventions' effectiveness and to inform the development of practices better suited to the needs of unemployed populations.
