Competencies vs Skills vs Experience: What You Are Really Hiring a Salesperson For
A founder tells me he needs someone who "knows our CRM, knows the industry, and has ten years in the field." All three are easy to check, and all three feel like a safe bet. That is the appeal. They are visible, countable, and they make a hiring decision feel objective.
Here is the catch. He just described skills, knowledge, and experience, which are the three easiest things to acquire or teach, and he said nothing about the sales competencies that take years to build and mostly cannot be trained into an adult on your timeline. He optimized the shortlist for the parts that matter least.
Getting clear on sales competencies versus skills versus experience is not a semantic exercise. It decides who makes your shortlist, and it is the foundation of a good sales selection process.
What is the difference between competencies, skills, and experience?
Keep the definitions plain.
Skills are learned, trainable abilities. Running a demo, writing a follow-up, building a sequence, navigating your CRM. You can teach most sales skills in a quarter to a willing adult.
Knowledge and experience are what someone has been exposed to. Your industry, your buyer, your product category, the years on the résumé. Useful context, quick to acquire, and, as the selection research keeps showing, a weak predictor of future performance on its own.
Competencies are the durable, underlying patterns of behaviour that make the skills work. Resilience after a no. Genuine curiosity in discovery. Conscientiousness, the discipline to do the unglamorous follow-up every single time. Coachability. These are stable, they run deep, and you are mostly not going to install them in someone during onboarding.
The old mistake, and it is one I have made, is to hire for the visible layer and hope the invisible one is there too. David McClelland made the case half a century ago that what you are tested on at the door often has little to do with what makes you good at the work. The idea has aged well.
Which sales competencies actually predict performance?
This is where the evidence earns its keep.
Conscientiousness, the trait behind reliable follow-through and self-discipline, predicts job performance across essentially every job studied. Barrick and Mount (1991) established that in a meta-analysis that has held up for decades. For a role that lives or dies on follow-up, that is not a nice-to-have, it is the engine.
General cognitive ability also predicts performance strongly and broadly (Schmidt & Hunter, 1998; Sackett et al., 2022), because it drives how fast someone learns your product, your market, and a complex deal. Notice that both of these are competencies you largely hire for, not skills you train.
Then there is fit. Kristof-Brown, Zimmerman, and Johnson (2005) found that how well a person fits the job and the organization relates meaningfully to performance, satisfaction, and whether they stay. A hunter who thrives on new logos will wither in a farming role, no matter how skilled. Competency without fit still misfires.
The uncomfortable through-line is that the predictors sit almost entirely in the layer you cannot see on a résumé and cannot teach in a quarter.
How do you hire for competencies instead of skills?
You hire for the durable layer on purpose, and you stop letting the easy-to-check layer run the decision.
Separate your criteria into three buckets before you post the role. Skills we will train, knowledge we will build, competencies we must hire for. Be honest about which bucket each requirement belongs in. Most "requirements" are trainable skills wearing a disguise.
Define each core competency as observable behaviour. Not "resilient" but "stays in a deal and keeps prospecting after a run of no's." You cannot assess a trait you cannot describe, and vague traits are where bias slips in. This is the raw material for How to Write a Sales Job Description.
Pick evidence for each competency. Behavioural questions for curiosity and coachability, a short work sample for the actual selling motion, and a validated assessment for conscientiousness and cognitive ability where the role justifies it.
Weight the competencies above the skills in your scorecard. If your scoring rewards CRM familiarity more than discovery instinct, you will keep hiring the trained and the mediocre. The weighting is the decision, which is why it belongs in The Sales Hiring Scorecard.
Keep every criterion job-related and defensible. Under the Ontario Human Rights Code, a requirement should be a bona fide need of the role, not a proxy that screens out protected groups. Confirm your competency model with an Ontario employment lawyer.
Does this mean experience does not matter?
No, and that is the honest nuance. Experience and industry knowledge shorten ramp time and reduce early risk, which is real money in a short sales cycle. If two candidates are genuinely equal on competencies and fit, relevant experience is a fair tiebreaker.
The error is making experience the entry gate instead of the tiebreaker. When you do that, you filter out the high-conscientiousness, highly coachable newcomer who would have outsold your experienced hire within a year, and you never even know you did it.
I spent years treating the résumé's experience line as the serious criterion and the "soft stuff" as a gut check at the end. I had it backwards. The soft stuff was the signal, and the hard stuff was the noise dressed up as rigour.
In short
Skills and experience are visible, trainable, and weak predictors. Competencies like conscientiousness, cognitive ability, and fit are durable, hard to train, and strong predictors. Hire for the competencies, train the skills, and use experience as a tiebreaker rather than the gate.
Key takeaways
Skills are trainable in a quarter, competencies take years and mostly cannot be installed in an adult on your timeline.
Conscientiousness predicts performance across virtually all jobs (Barrick & Mount, 1991), and for sales it drives the follow-through the job depends on.
Cognitive ability and person-job and person-organization fit are strong, well-evidenced predictors (Schmidt & Hunter, 1998; Sackett et al., 2022; Kristof-Brown et al., 2005).
Define each competency as observable behaviour and weight competencies above skills in your scorecard.
Use experience as a tiebreaker between otherwise equal candidates, not as the entry gate, and keep every criterion job-related under the Ontario Human Rights Code.
Frequently asked questions
What is the difference between a sales skill and a sales competency?
A skill is a trainable ability like running a demo or writing a sequence, usually teachable in a quarter. A competency is a durable behavioural pattern like resilience, curiosity, or conscientiousness that sits underneath the skills and is very hard to train into an adult. You train skills and you hire for competencies.
Which sales competencies predict performance best?
Conscientiousness and general cognitive ability are the most broadly evidenced predictors, and person-job and person-organization fit strongly affect performance and retention. These are the competencies worth weighting most heavily in your selection.
Should I still hire for sales experience?
Use it as a tiebreaker, not a gate. Relevant experience shortens ramp time, but on its own it is a weak predictor of performance. If two candidates are equal on competencies and fit, let experience break the tie.
