Structured Interviews for Sales Roles: Why They Work and How to Run One
A structured interview asks every candidate the same job-related questions, in the same order, and scores each answer against a rating guide written in advance. For sales roles, it's the most predictive interview format the research has found, and it's far better than the unstructured conversation most owners default to.
Ash here. I learned the limits of my own interviews the hard way. I always built my questions from the role's real competencies with the hiring manager. But I'd ask a big, open behavioural question, like "Tell me about the best deal you ever closed," and let the candidate run with it. Then candidates started preparing polished stories, more and more of them with AI help, and I realized that question had become something they could rehearse. The method that used to work had stopped telling me much.
How much better is a structured interview?
A lot. In a 2022 review published in the Journal of Applied Psychology, Sackett, Zhang, Berry and Lievens found structured interviews were the strongest single predictor of job performance among the methods they examined, with an operational validity of .42. Unstructured interviews came in far lower.
Canada's Public Service Commission puts it more simply in its interviewing guide: structured interviews can be up to twice as effective.
There's an honest caveat. A 2023 commentary by Huffcutt and Murphy pointed out that structured interviews also vary more in how well they work than other top predictors. How you build one matters. A structured interview done badly is just a scripted chat.
What makes an interview "structured"?
Researchers have identified a lot of possible ingredients. Campion, Palmer and Campion described 15 components of structure back in 1997, and a 2014 review by Levashina and colleagues counted up to 18, with studies using about six on average. You don't need all of them. These are the ones that matter most:
Questions built from a job analysis, meaning what the role actually requires
The same questions, in the same order, for every candidate
A rating guide written before the interviews, describing weak, solid and strong answers
Scoring each answer rather than forming one overall impression
Notes on what the candidate said and did
Independent scoring by each interviewer before the panel discusses
The Ontario Human Rights Commission recommends much the same for fair hiring: ask all applicants the same questions, and create an answer guide and marking scheme before interviews start.
How do you build a structured interview for a sales role?
Start from the profile of what the role needs, then build questions to test it.
Open with facts, not stories. Ask the questions that produce numbers and names first: What was your quota during your first year in that role? What training did you get? What was your quota last year, and what share did you hit? These are hard to rehearse into something they're not, and they give you something to check with references.
Break big questions into planned steps. Instead of one sprawling "tell me about your best deal," ask the same sequence every time: how you found the account, who you spoke to first, what stalled, what you did about it, how it closed, and what happened next. Every candidate gets the identical sequence. That last part matters, because asking different follow-ups to different candidates is how unfairness creeps in.
Mix behavioural and situational interview questions. Behavioural questions ask what someone did. Situational questions ask what they would do in a scenario drawn from your business. Both belong in a sales interview.
Write the rating guide before you meet anyone. This is your scorecard. For each question, describe what a weak, solid and strong answer sounds like. The Public Service Commission suggests a five-point scale is typically suitable.
How should you run the interview itself?
Use a small panel if you can. The Ontario Human Rights Commission suggests a multi-person panel for interviews.
Warm up, then start the scored questions. Give the candidate a minute to settle, then move into the structured part.
Take behavioural notes. A study by Burnett and colleagues found behavioural notes were linked to more valid ratings, while interviewers told to take general notes did worse than those who took none.
Score right after. The Public Service Commission recommends rating shortly afterward, with each interviewer scoring alone before the panel discusses.
Keep your records. The Ontario Human Rights Commission recommends keeping interview records for at least six months, or longer if there's a complaint. If you have 25 or more employees and publicly advertised the job, you also need to tell interviewed candidates within 45 days whether a hiring decision has been made, and keep those records for three years.
Save accommodation questions for later. The Human Rights Commission advises discussing disability and accommodation only after a conditional offer, unless the candidate raises it.
Does a structured interview protect you legally?
It helps. The Public Service Commission's guide reports a review of 158 US court cases in which unstructured interviews were found discriminatory in 59% of the challenges and structured interviews in none. That's US case law, not Ontario, and it's a review of legal outcomes rather than a validity study. But the logic carries over: a consistent, job-related process is easier to defend than a conversation nobody wrote down.
Structured doesn't mean robotic. You can still be warm, still have a real conversation in the warm-up, still let your personality show. You're just making sure the decision rests on what the candidate showed you, not on how much you enjoyed the hour.
Our own version sits inside a three-hour process we call the Certainty System. You don't need three hours to get most of the benefit. You need the same questions, a rating guide and the discipline to score before you decide. For what happens after the interview, see how to evaluate interview candidates for a sales role.
Work with us. Ashley Wesley, MA, CHRL, CIM, and our team are based in Guelph, Ontario. The Certainty System sits at the centre of our Final Candidate Review, alongside testing, references and benchmarks from your own people. Our handshake guarantee: if the report and process don't help, you don't pay.
In short
A structured interview asks every candidate the same job-related questions in the same order and scores each answer against a rating guide written in advance. A 2022 review in the Journal of Applied Psychology found structured interviews were the strongest single predictor of job performance, at .42. For sales roles, open with factual questions about quota and results, break big behavioural questions into the same planned steps for everyone, use a small panel, take behavioural notes and score independently before discussing.
Key takeaways
Structured interviews had the highest operational validity of the methods reviewed, at .42 (Sackett et al., 2022).
Canada's Public Service Commission says structured interviews can be up to twice as effective.
Structured interviews vary more in effectiveness than other top predictors, so how they're built matters (Huffcutt and Murphy, 2023).
Behavioural notes were linked to more valid interview ratings, while general notes did worse than no notes (Burnett et al., 1998).
The Ontario Human Rights Commission recommends asking all applicants the same questions, using an answer guide and keeping interview records for at least six months.
Frequently asked questions
What is a structured interview?
It's an interview where every candidate gets the same job-related questions in the same order, and each answer is scored against a rating guide written before the interviews. It's the opposite of an open-ended conversation.
What questions should I ask in a sales interview?
Start with factual questions about quota, attainment and training, which are hard to rehearse and easy to check. Then ask behavioural questions broken into planned steps, plus situational questions based on real scenarios from your business.
How long should a structured interview for a sales role be?
Long enough to cover every competency in your profile with a scored question. In our experience, many sales roles need 60 to 90 minutes. Senior roles justify more. Consistency matters more than length.
Is a structured interview required by law in Ontario?
No law requires a specific interview format. But the Ontario Human Rights Commission recommends asking all applicants the same questions and using a marking scheme, and a consistent process is easier to defend. Confirm your specific obligations with employment counsel.
