The stereotype of the great salesperson — loud, quick, relentlessly confident — has cost businesses a lot of money. It describes someone who interviews brilliantly and, often, sells adequately. The traits that actually correlate with performance are less theatrical.
The ones that travel across almost every sales role
- Curiosity. A genuine interest in how other businesses work. It is the engine behind good discovery, and it cannot be trained into someone who does not have it.
- Conscientiousness. Following up when nobody is watching, keeping the CRM honest, preparing for the call. Unglamorous, and the single most reliable predictor in the research.
- Resilience. Not the absence of a bad week, but a short recovery time.
- Self-awareness. Knowing what you are not good at and working around it.
- Comfort with discomfort. Asking about budget, challenging a stated requirement, sitting in a silence.
- Coachability. Feedback becomes changed behaviour rather than a conversation.
The ones that are overrated
Extroversion is the big one. It helps in some roles and gets in the way in others, and it correlates with interview performance far more strongly than with quota attainment. Plenty of excellent enterprise sellers are quiet, methodical and slightly reserved, which is exactly what a cautious technical buyer wants.
Confidence is similar. Useful up to a point, then it becomes an unwillingness to hear that the deal is not happening. Optimistic forecasting is a personality trait as much as a process failure.
Different seats need different people
This is the part most hiring processes miss. There is no single sales personality, and hiring for one produces a team that fails in the same way at the same time.
- SDRs need persistence, curiosity and fast recovery from rejection.
- Mid-market AEs need pace, organisation and commercial pragmatism.
- Enterprise AEs need patience, political intelligence and the ability to be interesting to a sceptical senior buyer over many months.
- Account managers and CSMs need consistency, care and the willingness to raise a difficult subject with someone they like.
- Sales leaders need the discipline to build a system instead of personally closing everything.
A brilliant enterprise seller often makes a poor SDR, and the reverse is true more often than people expect.
How to use this without turning it into a personality test
We are not advocating a questionnaire. Traits show up in behaviour, and behaviour shows up in specific stories. Ask about a deal that went wrong, a customer who was difficult, a time they were behind and what they did in week three. Score the same way for every candidate, in writing.
Then, critically, compare it against your own environment. The question is never "is this person a good salesperson?" It is "is this person likely to be good here, selling this, to these buyers, managed like this?" That is the question our fifth screening stage exists to answer, and it is the one that most often explains a hire who looked perfect on paper and did not work out.
