The ways in which natural language processing (NLP) can inform how veterans can improve effectiveness in translating military experience to workforce utility is underexplored. We design NLP experiments to evaluate the degree of explanation in veteran job interview responses as a proxy for perceived hireability. We examine linguistic and psycholinguistic features, context, and participant variability to investigate the mechanics of effective communication in employee selection. Results yield good performance when distinguishing between varying degrees of explanation in responses using LIWC features, indicating robustness of linguistic feature integration. Classifying Over- and Under-explained responses reflects challenges of class imbalance and the limitations of tested NLP methods for detecting subtleties in overly verbose or concise communication. Our findings have immediate applications for assistive technologies in job interview settings, and broader implications for enhancing automated communication assessment tools and refining strategies for training and interventions in communication-heavy fields.

Providing the right amount of explanation in an employment interview can help the interviewee effectively communicate their skills and experience to the interviewer and convince the she/he is the right candidate for the job. This paper examines natural language processing (NLP) approaches, including word-based tokenization, lexicon-based representations, and pre-trained embeddings with deep learning models, for detecting the degree of explanation in a job interview response. These are exemplified in a study of 24 military veterans who are the focal group of this study, since they can experience unique challenges in job interviews due to the unique verbal communication style that is prevalent in the military. Military veterans conducted mock interviews with industry recruiters and data from these interviews were transcribed and analyzed. Results indicate that the feasibility of automated NLP methods for detecting the degree of explanation in an interview response. Features based on tokenizer analysis are the most effective in detecting under-explained responses (i.e., 0.29 F1-score), while lexicon-based methods depict the higher performance in detecting over-explanation (i.e., 0.51 F1-score). Findings from this work lay the foundation for the design of intelligent assistive technologies that can provide personalized learning pathways to job candidates, especially those belonging to sensitive or under-represented populations, and helping them succeed in employment job interviews, ultimately contributing to an inclusive workforce.
