The purpose of this paper is to (a) develop a comprehensive understanding of the relationships between person–environment (PE) fit and employee engagement by shedding light on their intervening mechanisms; (b) represent how different types of PE fit and employee engagement interact; and (c) establish a comprehensive theoretical framework to guide future research based on the empirically examined constructs and their relationships. An integrative literature review of 51 empirical papers which analyzed the relationship between PE fit and employee engagement suggests that the antecedents of the relationship exist at the organizational, group, and individual levels and can be conceptualized as socialization, relationship building, and personal character, respectively; values–supplies fit, needs–supplies fit, and demands–abilities fit act as intervening mechanisms in the relationship; the relationship is temporal, reciprocal, and facilitated by human agency; and various outcomes result from the relationship. Implications for future research and practice are also discussed.
