The document discusses Behavioral Event Interviews (BEI) as a selection tool that judges candidates' competencies based on their past experiences rather than what they say they can do. It explains that BEIs involve an interviewer questioning a candidate about specific past events using a structured format while two recorders take notes without asking questions. The interviewer interrupts the candidate's story to have them divide the event into milestones and discuss their thoughts and actions at each point. After the interview, the panel rates the candidate on competencies like leadership and motivation based on how they demonstrated each skill. BEIs differ from simple interviews by focusing on how candidates actually behaved in real past situations rather than hypothetical scenarios.
