Structured Interviews: The Simplest Upgrade to Your Hiring

Interviews are the most common way organisations choose people, and one of the least consistent. Two candidates for the same role may be asked completely different questions by different interviewers, assessed against unspoken criteria, and judged largely on whether the interviewer liked them. The result is decisions that are hard to defend and often wrong.

Structured interviews fix much of this with a simple change: every candidate for a role is asked the same core questions, linked to the job's requirements, and answers are scored against an agreed guide. Decades of research in occupational psychology have found that structured interviews predict job performance considerably better than unstructured ones. They are also fairer, easier to defend and, once set up, not much more work.

What makes an interview structured?

A structured interview has four features:

1. Questions based on the job. Questions come from an analysis of what the role actually requires.
2. The same questions for every candidate. Interviewers may ask follow-up questions, but the core questions do not change.
3. A scoring guide. Each question has a description of what weak, acceptable and strong answers look like.
4. Independent scoring. Each interviewer scores answers on their own before discussing with others.

Why unstructured interviews fall short

Informal interviews feel natural, but they invite bias and noise:

• First impressions dominate. Interviewers often form a view within minutes and spend the rest of the conversation confirming it.
• Similarity bias. People tend to rate candidates more highly when they share backgrounds, interests or communication styles.
• Inconsistency. Different questions for different candidates make fair comparison impossible.
• Charisma over competence. Confident, articulate candidates can outshine more capable but quieter ones.

Structure does not remove human judgement. It focuses it on evidence relevant to the job.

Step 1: Define what the role needs

Before writing questions, agree the four to six capabilities that matter most for success in the role. Talk to the hiring manager and people who do or work closely with the job. Be specific: "manages competing priorities in a fast-changing environment" is more useful than "good organiser".

Step 2: Write good questions

Two types of question work well.

Past behaviour questions

Ask candidates to describe what they actually did in a relevant situation:

• "Tell me about a time you had to deliver an important piece of work with an unexpectedly short deadline. What did you do?"
• "Describe a situation where you disagreed with a colleague about how to approach a problem. How did you handle it?"

Follow up to get specifics: what was your role, what exactly did you do, what happened as a result?

Situational questions

Present a realistic scenario from the job and ask how the candidate would handle it:

• "A customer calls, upset that a delivery promised for today will now arrive next week. What do you do?"

Avoid hypothetical questions with obvious "right" answers, and avoid trick questions or brainteasers, which have little connection to job performance.

Step 3: Create a scoring guide

For each question, describe what a weak, acceptable and strong answer would include. For example, for the short-deadline question:

• Weak: vague description; focuses on working longer hours; no clear actions or result.
• Acceptable: describes prioritising tasks and communicating with stakeholders; reasonable result.
• Strong: clearly explains how they assessed priorities, negotiated scope or support, kept stakeholders informed, delivered the work and reflected on what they would do differently.

A simple scale, such as 1 to 4 or 1 to 5, with these descriptions anchored to points on the scale, helps interviewers score consistently.

Step 4: Run interviews consistently

• Use a panel of two or three trained interviewers where practical, from different backgrounds.
• Take notes of what candidates actually say, not impressions.
• Score independently immediately after each interview, before any discussion.
• Then discuss, starting with the evidence for each capability, and resolve differences by looking at the notes.

Step 5: Make decisions on the evidence

Combine scores across capabilities and interviewers. Use the discussion to check for errors and missing evidence, not to override the evidence with a general feeling. If a strong overall preference contradicts the scores, ask why.

Fairness and inclusion

Structured interviews support fairer hiring because every candidate is judged against the same criteria. They also make it easier to provide reasonable adjustments, such as sharing questions in advance or allowing extra time, without compromising consistency. Many organisations find that structured processes help them widen the range of people they hire.

Common objections

• "It feels robotic." Interviewers can still be warm, explain the process and ask natural follow-up questions. Candidates generally appreciate the fairness.
• "I can tell within five minutes." That is exactly the kind of snap judgement structure is designed to check.
• "It takes too long to set up." For a recurring role, questions and guides can be reused many times. A first version takes an hour or two.

How mature is your hiring?

Updated October 2026: we have added a Talent Acquisition assessment. It covers hiring demand and role definition, employer brand, sourcing and pipelines, selection and assessment, candidate experience, and hiring analytics and onboarding handover.

Fair selection is a central part of building an inclusive organisation. The Diversity, Equity & Inclusion assessment looks at equitable systems and processes alongside leadership, data, culture and education.

Frequently asked questions

Can we share interview questions with candidates in advance?

Many organisations do, or share the topics, because it helps candidates give their best evidence and supports neurodivergent and disabled candidates. Scoring guides keep assessment rigorous.

How many interviewers should there be?

Two or three trained interviewers usually balances reliability with practicality. Independent scoring matters more than the exact number.

Are structured interviews suitable for senior roles?

Yes. The questions become more complex and the capabilities more strategic, but the principles of job-relevant questions, consistent assessment and evidence-based decisions apply at every level.
