How to Run a Sales Role-Play Interview

Candidate Assessment
Written by Ashley Wesley

A sales role-play interview is a short, realistic selling scenario where the candidate sells to someone playing your buyer, and you score what they actually do against a guide written in advance. Run well, it shows you skills an interview conversation can't. Run badly, it mostly shows you who is comfortable performing on cue.

Why bother with a role play at all?

Here's the fair part. A conversation-only interview is easy to run and feels thorough. You ask good questions, the candidate gives good answers, everyone shakes hands.

The trouble is that sales is a performance skill, and talking about a skill isn't the same as doing it. Research on hiring methods backs the instinct to watch the work. In the largest recent review of selection methods, work samples had an average validity of .33, behind structured interviews at .42 (Sackett et al., 2022, 2023). A role play is a kind of work sample, and it pairs naturally with a structured interview rather than replacing it.

There's also a sales-specific study worth knowing. In a German field study of salesperson selection, researchers followed 93 hires who stayed at least a year. A newer way of scoring their assessment centre exercises, built around the candidate's drive to get ahead combined with their social skill, reached an operational validity of .45 against sales revenue a year later, about 25% higher than the .36 that earlier research found for assessment centres scored the traditional way (Kückelhaus et al., 2022). The interaction of drive and social skill explained an extra 15.3% of the variance in sales performance, over and above the other scores (Kückelhaus et al., 2022).

One field study isn't a law. But it's a useful signal: how you score the exercise matters as much as running it.

What's the catch with role plays?

Two catches, and both are fixable.

Everyone sells hard for 15 minutes. A role play shows what a candidate can do when it counts, which isn't always what they will do on a slow Tuesday in February. That's why the role play is one piece of evidence, not the verdict. Check the everyday habits through past-behaviour questions and references.

Vague scoring turns into gut feel. If the panel just discusses "how it felt," you're back to rating confidence and polish. Write down what a strong, average and weak response looks like before the first candidate walks in.

How to run a sales role-play interview

  1. Build the scenario from a real deal. Use a real (disguised) customer situation: who the buyer is, what they think they need, what they actually need, one honest objection and one constraint like budget or timing. Generic "sell me this pen" exercises reward patter, not judgment.
  2. Hide one thing that only good questions uncover. Give the buyer a real need they'll mention only if asked. Strong candidates find it. Weak ones pitch the first problem they hear. Our post on interview answers that show a salesperson listens has more on what to watch for.
  3. Give everyone the same brief and the same time. Same scenario, same information, same preparation time, same buyer behaviour. Consistency is what makes candidates comparable, and it's what the Ontario Human Rights Commission advises for interviews generally: "develop set questions in advance, and ask all applicants the same questions" (Ontario Human Rights Commission [OHRC], 2008, section IV-5).
  4. Score behaviour, not charisma. Pick four or five things to score: questions asked before recommending, how accurately they play back what the buyer said, how they handle the objection, whether the recommendation fits the need, and how they agree on a next step. Rate each one right after the exercise, before the panel talks.
  5. Have one person play the buyer and another score. It's hard to play a convincing buyer and take good notes at the same time.
  6. Debrief the candidate for two minutes. Ask, "What would you do differently if you ran that again?" How they answer tells you a lot about coachability. Our post on the coachable sales candidate covers why that matters.
  7. Offer accommodation, and say so in writing. Under Ontario's accessibility standards, employers must tell applicants who are selected for an assessment that "accommodations are available upon request in relation to the materials or processes to be used," and then consult with the applicant and provide a suitable accommodation if asked (Integrated Accessibility Standards, O. Reg. 191/11, s. 23). A role play is an assessment process, so this applies.
  8. Keep it job-related. Ontario's Human Rights Code treats a requirement that screens out a protected group as discriminatory unless it is "reasonable and bona fide in the circumstances" and the group can't be accommodated without undue hardship (Human Rights Code, 1990, s. 11). A role play built on the real job is much easier to defend than a stress test that isn't. Confirm your process with employment counsel.

How long should a sales role play be?

Long enough to see a full conversation: discovery, a recommendation, an objection, a next step. For most sales roles, 15 to 25 minutes of selling plus a few minutes of debrief is plenty. More than that starts to look like unpaid work, which raises a separate issue in Ontario, since 2024 changes to the Employment Standards Act treat trial-period work as employment (Government of Ontario, 2024).

Two things that are both true

We'll own something on behalf of HR. A lot of us run role plays because they feel rigorous, then score them on whether we'd enjoy buying from the person. That's the same gut feel we were trying to get away from, just with props.

A role play is one of the best looks you'll get at how someone sells. And it's only as good as the scenario you build and the scoring you write before anyone walks in. For owners in Guelph and across Ontario, a one-page scenario and a one-page scoring guide are the whole investment. They're worth it.

In short

A sales role-play interview puts the candidate in a realistic selling scenario and scores what they do against a written guide. Work samples like role plays averaged .33 validity in a recent major review, behind structured interviews at .42 (Sackett et al., 2022, 2023), so they work best alongside a structured interview. Build the scenario from a real deal, hide a need that only good questions uncover, give every candidate the same brief, score behaviours rather than charisma, and in Ontario, offer accommodation for the assessment (O. Reg. 191/11, s. 23).

Key takeaways

  • Work samples averaged .33 validity and structured interviews .42 in the most recent large review of selection methods (Sackett et al., 2022, 2023).
  • In one German field study of 93 sales hires, a new way of scoring assessment centre exercises reached .45 operational validity against sales revenue a year later, about 25% above the .36 benchmark for traditional scoring (Kückelhaus et al., 2022).
  • How you score a role play matters as much as running it: write the scoring guide before the first candidate.
  • A role play shows what a candidate can do when it counts; check everyday habits with past-behaviour questions and references.
  • In Ontario, applicants selected for an assessment must be told accommodation is available on request (O. Reg. 191/11, s. 23).

Frequently asked questions

What is a sales role-play interview?

It's a short, realistic selling scenario during the hiring process, where the candidate sells to someone playing a buyer. The panel scores what the candidate does, such as the questions they ask and how they handle an objection, against a guide written in advance.

Are role plays a good way to hire salespeople?

They're a good part of the process. Work samples averaged .33 validity in a recent major review (Sackett et al., 2022, 2023). Use the role play alongside a structured interview and reference checks rather than on its own.

Should I tell candidates about the role play in advance?

Yes. Tell them there will be a role play, how long it is and what it's about at a high level. In Ontario you also need to tell selected applicants that accommodation is available on request (O. Reg. 191/11, s. 23).

Do I have to pay candidates for a role play in Ontario?

A short role play in an interview is generally treated differently from a trial period of real work, but Ontario's rules on unpaid trial work changed in 2024. Keep the exercise short and clearly a simulation, and confirm with employment counsel. This is general information, not legal advice.
