A Competency-Based Interview (CBI) is a structured interview technique used by employers to assess a candidate's skills and behaviors. It focuses on specific competencies, such as teamwork, problem-solving, and communication, by asking candidates to provide examples from their past experiences that demonstrate these abilities. During a CBI, interviewers typically ask open-ended questions that prompt candidates to describe situations where they successfully applied relevant competencies. This method helps employers predict future performance based on past behavior, making it a valuable tool in the hiring process.
