A structured interview asks every candidate for a role the same predetermined questions in the same order, scored against a standardized, anchored rating scale, unlike an unstructured interview, which is closer to a free-flowing conversation that varies candidate to candidate.

Why it reduces bias

Research comparing the two formats consistently finds structured interviews more predictive of actual job performance, with meta-analyses reporting notably higher validity for structured formats than unstructured ones, though the exact figures vary by study. The mechanism is fairly intuitive: predetermined questions limit an interviewer’s confirmation bias, an anchored scale reduces the halo effect where one strong answer colors the whole evaluation, and consistent criteria across candidates reduce contrast effects, where a candidate looks better or worse mainly because of who interviewed just before them. Unstructured interviews, by contrast, are considerably more exposed to bias around gender, background and even how closely a candidate resembles the interviewer.

Frequently asked questions

Does “structured” mean the same as “panel”?

No, these are independent choices. An interview can be structured with one interviewer or several, and a panel interview can itself be structured or unstructured.

Can a structured interview still feel natural to the candidate?

Yes, a well-run one follows the same core questions without feeling like a rigid script, the interviewer still probes and follows up naturally within each question.

Why don’t more companies use structured interviews if they work better?

Building and maintaining consistent question sets and scoring rubrics takes upfront effort that many interviewers skip in favor of an improvised conversation.
