Characterizing Hirability via Personality and Behavior

TL;DR

This study models job hirability as a personality trait using multimodal behavioral cues and demonstrates that a two-step prediction process from behavioral data to personality and then to hirability outperforms direct prediction, with multimodal cues enhancing accuracy.

Contribution

It introduces a novel approach of modeling hirability as a personality construct and evaluates multimodal behavioral cues for improved hirability prediction.

Findings

Two-step prediction process outperforms direct prediction.

Visual cues like eye and body movements are as effective as face cues.

Multimodal behavior influences personality impressions, e.g., cuss words affect Conscientiousness perception.

Abstract

While personality traits have been extensively modeled as behavioral constructs, we model \textbf{\textit{job hirability}} as a \emph{personality construct}. On the {\emph{First Impressions Candidate Screening}} (FICS) dataset, we examine relationships among personality and hirability measures. Modeling hirability as a discrete/continuous variable with the \emph{big-five} personality traits as predictors, we utilize (a) apparent personality annotations, and (b) personality estimates obtained via audio, visual and textual cues for hirability prediction (HP). We also examine the efficacy of a two-step HP process involving (1) personality estimation from multimodal behavioral cues, followed by (2) HP from personality estimates. Interesting results from experiments performed on $\approx$~5000 FICS videos are as follows. (1) For each of the \emph{text}, \emph{audio} and \emph{visual} modalities, HP via the above two-step process is more effective than directly predicting from behavioral cues. Superior results are achieved when hirability is modeled as a continuous vis-\'a-vis categorical variable. (2) Among visual cues, eye and bodily information achieve performance comparable to face cues for predicting personality and hirability. (3) Explanatory analyses reveal the impact of multimodal behavior on personality impressions; \eg, Conscientiousness impressions are impacted by the use of \emph{cuss words} (verbal behavior), and \emph{eye movements} (non-verbal behavior), confirming prior observations.
