<p>Authenticity at work has become a popular topic among both researchers and practitioners. Yet, what authenticity looks like and how to assess it have remained elusive. Our research uses automated video interviews (AVIs) to empirically identify behavioral cues of authenticity and further examines whether these cues differ between self-evaluations of authenticity and others’ evaluations of one’s authenticity. Using AVI recordings of mock job interviews, we found that using 1st-person singular and present tense, as well as less planned, less filtered, and less formal speech, were related to self-assessed authenticity. Interestingly, the behavioral cues related to interviewer-assessed authenticity were different: more total words, more words per minute, fewer “big” words, and fewer adverbs. Fewer words per sentence was related to both self- and interviewer-assessed authenticity. Notably, we did not find any nonverbal or paraverbal behavioral cues of authenticity. Our research provides a novel, technology-based perspective of the behavioral cues of authenticity and the implications of these findings at work and beyond.</p>
