Which selection method is most associated with high validity for many job types and why?

• A. Unstructured interviews, because they capture candidate context more naturally.
• B. Structured interviews, because standardized questions reduce bias and improve reliability and predictive validity.
• C. Biodata, because it collects personal histories.
• D. Assessment centers, because they require expensive resources.

Answer: (B)

Structured interviews are best because using standardized questions and a consistent scoring process reduces interviewer bias and boosts reliability. When interviewers ask the same questions and evaluate answers with a clear rubric, responses can be compared more fairly, and the results more reliably predict job performance across many different roles. This standardized approach aligns with what a job analysis identifies as the key competencies, so the method tends to have higher predictive validity overall. Unstructured interviews can drift based on how the interviewer perceives the candidate, leading to lower reliability and validity. Biodata can be predictive but may not be equally relevant for every job and can introduce cultural or interpretation challenges. Assessment centers can be very valid but require substantial resources and are not as universally applicable across all job types as structured interviews.
