Interviewing a salesperson is a strange experience.

In most interviews, polish is a distraction. In a sales interview, polish is the product. The candidate builds rapport in the first two minutes, mirrors your language, handles your objections gracefully and closes with a confident question about next steps.

You come out of the room thinking, “Well, they certainly sold me.”

And that’s exactly the problem. They did. That’s their job. What you still don’t know is whether they can do it again, every week, with a sceptical purchase manager who has three other quotes on the desk and no interest in rapport.

Here’s a question worth sitting with: if the interview rewards the very skill the candidate uses to win the interview, how do you tell a real seller from a good performer in a meeting room?

That’s what a sales competency assessment is for.

Why Sales Hiring Is Harder Than It Looks

Sales seems like the easiest function to hire for. Results are measurable. Candidates come with numbers. “I achieved 130% of the target last year” sounds like evidence.

The honest answer is that sales numbers on a CV are some of the least comparable numbers in hiring. A strong result can come from a generous territory, a market that was growing anyway, a product with little competition, or a large account inherited from someone else. A weak result can hide a genuinely capable seller who was handed a struggling region.

So most sales hiring ends up relying on two things that don’t travel well: numbers without context, and a conversation the candidate is unusually good at.

What’s missing is evidence of the behaviours that produce sales results, whatever the territory.

What Sales Competency Actually Means

Interest in what makes salespeople succeed goes back a long way. In a classic piece for Harvard Business Review, “What Makes a Good Salesman”, David Mayer and Herbert Greenberg argued that two basic qualities sit underneath sales success: empathy, the ability to sense how a customer feels, and ego drive, a personal need to make the sale. Decades later, most sales leaders would still recognise both.

In practice, those qualities show up as a set of observable behaviours.

Sales competency	What good looks like
Prospecting discipline	Keeps the pipeline full, even in good months
Needs discovery	Asks before pitching, and listens to the answer
Resilience	Recovers quickly from rejection and tries again
Negotiation	Protects value instead of discounting first
Follow-through	Does what was promised, without reminders
Ethical judgement	Won’t overpromise to close a deal

None of these shows up reliably in a CV. Some barely show up in an interview. All of them show up in how people behave when the situation feels real.

Not Every Sales Role Needs the Same Seller

A common mistake is treating “sales” as one job. It isn’t. A field seller opening new accounts and a key account manager growing a large client need quite different strengths.

Sales role	Competencies that matter most
New business (hunter)	Prospecting, resilience, persuasion
Account management (farmer)	Relationship building, needs discovery, follow-through
Key accounts	Strategic thinking, negotiation, stakeholder management
Channel and distributor sales	Influence without authority, planning, consistency
Inside or tele sales	Pace, resilience, clear communication

This is why a single generic sales assessment test rarely gives you the full picture. The right assessment starts with the right role profile. A strong hunter placed in an account management role can be just as much of a hiring mistake as a weak seller.

Sales Assessment Test or Sales Competency Assessment?

The terms are often used interchangeably, but they mean different things.

A sales assessment test is a single tool, usually an online questionnaire or task that measures certain traits or behaviours. A sales competency assessment is the wider approach. It defines what success looks like in the specific role, then uses more than one method to gather evidence against it.

Each method sees something different.

Method	What it reveals
Behavioural assessment	How candidates actually respond, not how they describe themselves
Sales role play	Needs discovery, objection handling and negotiation in action
Structured interview	Context behind past results and real examples
Situational judgement task	Choices under pressure and ethical judgement

Combining two or three of these gives you a far more reliable picture than any one of them alone.

Assess Your Sales Candidates

How to Run a Sales Competency Assessment

1. Build the role profile first

Talk to your best performers and their managers. What do the top sellers in this specific role do differently? Turn the answers into five or six competencies with clear behavioural indicators. This is the standard every candidate will be measured against.

2. Screen on behaviour, not just CVs

For volume sales hiring, such as field sales, retail or inside sales teams, interviewing every applicant isn’t practical. A behaviour-based screening tool helps here. Ezyss®, our gamified assessment solution, measures behaviour through interactive tasks in about 25 minutes, captures more than 3,000 behavioural data points and produces instant role fitment reports. Because it’s language-independent, candidates aren’t filtered out for reasons that have nothing to do with selling.

3. Watch them sell

A short role play tells you more than an hour of questions. Give the candidate a realistic brief: a hesitant customer, a price objection, a competitor who has offered a discount. Then watch. Do they ask questions before pitching? Do they discount at the first push? Do they recover when the buyer says no?

4. Interview for the story behind the numbers

When a candidate quotes a result, ask for the context. What was the target? How many in the team achieved it? How much came from new accounts and how much from existing ones? What changed in the market that year? Strong sellers answer these questions easily and in detail. Weaker ones tend to repeat the headline number.

5. Decide against the profile

Bring the evidence together and compare each candidate with the role profile, not with each other’s personalities. The most charming person in the process isn’t always the best fit for a role that depends on discipline and follow-through.

Sales Capability Assessment for Existing Teams

Assessment isn’t only a hiring tool. A sales capability assessment across an existing team shows where the real gaps are. That’s useful, because sales training budgets are often spent on what’s fashionable rather than what’s missing.

One team may be excellent at building relationships but weak at negotiation. Another may close well but have thin pipelines. Knowing the difference means development can target the right skills, ideally through structured learning journeys that build habits over weeks rather than in a single workshop.

It also helps with one of the riskiest decisions in sales: promoting a top seller into a sales manager role. Selling and managing sellers are different jobs. Before that promotion, a behavioural assessment or a full assessment development centre shows whether the person is ready to lead a team, not just a territory.

Clear measures matter too. When sales roles have well-designed KPIs that balance results with the activities that drive them, assessment findings and performance data start telling the same story.

Building the Skill In-House

Organisations that hire salespeople regularly benefit from HR and sales leaders who understand assessment well enough to design role profiles, run role plays and read reports with confidence. Many build that capability through Assessment for Talent Management (ATM), which covers assessment science across hiring, development and succession.

Since 2009, we’ve worked with more than 300 organisations and 190,000+ professionals. In sales hiring, the pattern is consistent: the best decisions come from watching how people sell, not from listening to how well they talk about selling. If you enjoy thinking about questions like these, the Friday Fulcrum explores them every week.

Every salesperson can sell you on themselves for an hour. The real question is whether they can do it on a wet Monday morning, in a market that isn’t buying.

Frequently Asked Questions

1. What is a sales competency assessment?

A sales competency assessment evaluates candidates or employees against the specific behaviours that drive success in a sales role, such as prospecting discipline, needs discovery, resilience, negotiation and follow-through. It usually combines several methods, including behavioural assessments, role plays and structured interviews.

2. What is a sales assessment test?

A sales assessment test is a single tool, often an online questionnaire or task-based assessment, used to measure traits or behaviours linked to sales performance. It works best as one part of a wider sales competency assessment built around the specific role.

3. What is a sales capability assessment?

A sales capability assessment measures the strengths and gaps of an existing sales team against the competencies their roles require. It helps organisations target training, plan development and make better decisions about promoting sellers into management.

4. Which competencies matter most in sales roles?

It depends on the role. New business roles need prospecting and resilience, account management roles need relationship building and follow-through, and key account roles need negotiation and strategic thinking. A clear role profile should come before any assessment.

5. Are sales role plays useful in hiring?

Yes. A realistic role play shows how a candidate actually handles needs discovery, objections and negotiation, which is far harder to fake than an interview answer. It works best when scored against clear behavioural criteria.

6. Should top salespeople be promoted to sales managers?

Not automatically. Selling and managing sellers require different strengths. A behavioural assessment or assessment development centre before the promotion shows whether the person is ready to lead a team.
