This study aimed to investigate the relationship between the five personality traits (Costa & McCrae, 1992) and the levels of emotional intelligence (Bar-On, 1997) in order to draw some conclusions that would benefit adults who want to increase their job performance in terms of soft skills. Our exploratory focus was also motivated by the scarcity of studies on these issues in the Romanian context. The results revealed that introversion-extraversion factor influences the level of emotional intelligence, that there are differences between the extremes of the big five dimensions due to different levels of EI; that there is a correlation between the extraversion and consciousness factors and EI; that personality factors interact among them to influence the levels of emotional intelligence. The findings may be used to teach adults how to understand themselves better, to train leaders to understand their personnel and the dynamics of their group.
