This study looks at the relevance of Holland's Hexagonal Model of vocational interests within a collectivistic cultural context by examining the alignment between RIASEC personality types and occupational daydreams among Indonesian high school students. Informed by a mixed-methods approach, 649 students completed the Self-Directed Search (SDS), with a subset participating in follow-up interviews. Quantitative analyzes supported the model's structural validity, showing significant correlations between adjacent RIASEC types and a moderate fit to the hexagonal structure, as indicated by Mardia's Configuration Validity Index. The C-Index revealed moderate congruence between students' personality profiles and their career aspirations. Qualitative findings emphasized the strong influence of family expectations, peer dynamics, and sociocultural norms on students' vocational imaginings. Although Holland's model remains theoretically sound, its practical application in collectivist settings may require adaptation to account for external social influences. The findings advocate the need for culturally responsive career guidance that balances individual interests with collective expectations, offering valuable insights for educators, counselors, and policymakers in similar sociocultural contexts.
