What is the STAR interview method AND how do you evaluate behavioral competency?

The STAR interview method is a structured behavioral assessment framework that evaluates candidate competencies based on specific past performance. Built on the industrial psychology principle that past behavior is the single most reliable predictor of future performance, STAR divides a candidate's answer into four distinct components: Situation, Task, Action, and Result. In talent acquisition, the STAR method prevents interviewers from falling prey to charismatic storytelling or vague theoretical claims. When asked “How do you handle difficult stakeholders?”, an unprepared interviewer accepts generic claims like “I maintain great communication.” A trained STAR interviewer insists on an actual, verifiable historical incident, analyzing whether the candidate personally drove the outcome or merely observed it from the sidelines.
