During a competency-based interview, each question is intended to test one or more specific skills. The answers are then matched against predetermined standards and judged.
A competency-based interview is also referred to as structured or behavioral interview.
Competency-based interviews differ from unstructured interviews in several ways. Unstructured interviews are basically conversations where the interviewers ask several questions to get an overall impression of the candidate.
Competency-based interviews are more methodical than unstructured interviews; each question inquires about a specific skill or ability. Candidates are asked questions relating to their behavior in specific situations, which they then need to back up with real instances. The interviewers will then probe further into the examples by asking for specific explanations about the candidate’s behavior or skills.
