Structured interview

Why structure beats conversation

Unstructured interviews feel insightful and predict poorly; selection research has shown it for decades. The reasons are mechanical: without fixed questions, each candidate faces a different test, so scores are not comparable; without anchored criteria, "good answer" means "answer I liked", and confidence, similarity and first impressions do the deciding. Structure removes the noise, which is why structured interviews sit near the top of validity rankings for selection methods while the friendly chat sits near the bottom.

What a structured interview requires

Four commitments made before the first candidate walks in: questions derived from what the role actually requires, the same set asked of everyone, a scoring rubric with behaviourally anchored levels (what does a 2 sound like, what does a 4 sound like), and scores recorded independently by each interviewer before discussion. None of it is complicated. All of it is regularly skipped the moment a hiring manager is busy, which is when bad hires happen.

The fairness dividend

Structure is also the defensibility layer. Same questions, same criteria and documented scores are what make a selection decision explainable to a rejected candidate, a regulator or a general protections claim. And because structure narrows the room for gut-feel bias, it reliably improves outcomes for candidates who do not resemble the last person hired, which is where most unstructured processes quietly fail.
