During the summer of 2016, I interned at a small start-up called Juji in the South Bay. There, I designed and developed a web-based interface for recruiters/HR to sort candidates by automatically inferred personality traits, as well as a chat interface to conduct virtual interviews and where candidates could see their inferred personalities. Using this system, I helped design and run a field deployment to over 300 real job applicants, testing the effects of the personalities of both virtual agents and interviewees on trust.

We present an intelligent virtual interviewer that engages with a user in a text-based conversation and automatically infers the user's psychological traits, such as personality. We investigate how the personality of a virtual interviewer influences a user's behavior from two perspectives: the user's willingness to confide in, and listen to, a virtual interviewer. We have developed two virtual interviewers with distinct personalities and deployed them in a real-world recruiting event. We present findings from completed interviews with 316 actual job applicants. Notably, users are more willing to confide in and listen to a virtual interviewer with a serious, assertive personality. Moreover, users' personality traits, inferred from their chat text, influence their perception of a virtual interviewer, and their willingness to confide in and listen to a virtual interviewer. Finally, we discuss the implications of our work on building hyper-personalized, intelligent agents based on user traits.
