Research Context

‚ÄčOur study aims to investigate the creative process involved in designing good quality interview questions. We are hoping to unpick key factors that may enhance or inhibit an interviewer's ability to ask the right question at the right time. This study is related to a larger project that has been investigating a range of interview techniques designed to help detect deception in interviews. Hopefully, this research will help us to identify which techniques are effective, and allow us to make suggestions concerning the best way to utilise those techniques.

Research Methodology

‚ÄčThe current experiment is conducted entirely online. It features a series of short interview clips and after each the participant is asked to come up with a question that they would ask next. We are attempting to recruit 40 expert participants with relevant interviewing experience.
