What the job is not

Almost everything the public believes about selling describes a job that either no longer exists or never should have. The images come from film, from consumer double-glazing, and from 1980s American stock-broking. None describes selling clinical software to an NHS trust.

Myth 1: "Some people are born salespeople"

There is no evidence for a sales gene and quite a lot against it. The most-cited practitioner dataset — Mark Roberge's hiring analysis at HubSpot, in section 3 — identifies learnable, observable behaviours, not innate charisma. Neil Rackham's SPIN Selling research, built on observation of more than 35,000 sales calls, reached the same conclusion decades earlier: the difference between better and worse performers lay in what they did in the call, particularly the questions they asked.

Why the myth persists. The visible part of the job — being fluent in a room — looks like a personality trait. The invisible part, where deals are won, looks like preparation, note-taking, follow-up and process discipline. Nobody makes a film about that.

Myth 2: "Selling ice to Eskimos"

The phrase describes fraud, not selling — and it is dated and offensive besides (the peoples in question are Inuit, among others). Persuading someone to buy what they don't need is viable only where the buyer never returns; in B2B they must be implemented, supported, renewed and used as a reference. In life sciences this is doubly true, because the market is small and everybody talks: there are only so many NHS trusts and mid-size UK biotechs, people move between them, and a rep who oversells in one trust has damaged their access to the next five.

Myth 3: The Wolf of Wall Street

The film depicts a crime. Jordan Belfort's firm, Stratton Oakmont, ran a pump-and-dump operation selling worthless stock to retail investors. Belfort was indicted in 1999, pleaded guilty to securities fraud and money laundering, served around 22 months, and was ordered to pay restitution to the investors he defrauded.

Structurally it is the opposite of B2B enterprise selling. A boiler room sells a low-value product to an unsophisticated individual once, at speed, under pressure, with no consequences after the money moves. Enterprise B2B sells a high-value product to a professional committee, slowly, with the seller personally on the hook for whether it works for three years. Every incentive runs the other way.

Myth 4: "It's manipulation"

You cannot manipulate a committee of eight people over nine months. The buyer knows more about their own organisation, budget and politics than you ever will, researches you independently — Gartner's 17% figure is that story in one number — and compares notes internally after you leave. The distinction that matters is between persuasion (helping someone see a case that is genuinely true) and manipulation (getting someone to act against their own interest). In a market with renewals, references and small professional networks, manipulation is not merely wrong; it is commercially stupid.

Myth 5: "It's all about the pitch"

The pitch is the least important part of a complex deal. Most of the outcome is set before you present anything: whether you found a genuine, quantified problem; whether you're talking to someone who can act; whether there is a reason to decide this year rather than next. Sellers who lead with the pitch are answering a question the buyer hasn't asked.

So what is it closer to?

Consultative diagnosis. The clinical analogy is exact: history-taking, examination, differential diagnosis, then treatment. Prescribing before diagnosing is malpractice in medicine and loses deals in sales. Modules 3 and 4 are essentially a training in structured diagnosis.

Project management without authority. A complex sale is a change project inside somebody else's organisation, involving people who don't report to you, on a timeline you don't control: coordinating a pilot, chasing an information-governance review, scheduling a committee, holding it together for months.

Research, writing and internal selling. Board papers and published strategies in; recap emails, business cases and proposals out — plus persuading your own legal, product and finance teams to move. A rep who writes clearly and briefly has an advantage that compounds daily.

Field note

The Wolf image hasn't disappeared from the UK market; it has retreated to a corner of it. If an advert promises "uncapped commission" on a base near minimum wage, describes the culture with bells and gongs, is vague about the product, or is commission-only, you have found the corner. Those roles churn people relentlessly, and the experience they give is not what a serious B2B employer wants to see — it is entirely possible to spend a year in one and come out less employable than you went in.

3. Who actually thrives

The honest starting point: prediction in sales hiring is weak. If it were strong, sales teams wouldn't have the turnover they have. What follows is the best evidence available with its limits visible, not a personality horoscope.

The Roberge data — one company's regression, taken seriously

Mark Roberge was HubSpot's VP of Sales and later Chief Revenue Officer, building the sales organisation through the company's growth from zero to over $100m. Unusually, he treated hiring as a measurement problem: he scored every candidate against defined characteristics at interview, then correlated those scores against actual post-hire performance.

Voice from the field

"After about a year of hiring, I had accumulated enough data points to run a formal regression analysis, correlating the hiring characteristics with post-hire sales success."
— Mark Roberge, The Sales Acceleration Formula (2015)

Five characteristics came out as predictive:

• Coachability — absorbing and applying coaching, which Roberge treats as the standout. When someone tells you what you did wrong on a call, is your first move to understand it or to explain yourself?
• Curiosity — understanding a customer's context through questioning and listening. Not sociability; genuine interest in how someone else's world works.
• Prior success — a history of top performance or remarkable achievement. Note carefully: not prior success in sales.
• Intelligence — learning complex concepts quickly and explaining them simply. In life sciences this is doubled: absorb the science and translate it for a procurement officer.
• Work ethic — proactively pursuing the mission with consistent daily activity.

The caveats, plainly. One company's data, from one era, in one motion — an inbound-led software business in the late 2000s and early 2010s — with traits scored by Roberge's own interview process, so the analysis partly measures what he could detect at interview. It is not peer-reviewed and has not been replicated across industries. Treat it as the most serious practitioner dataset available and a good hypothesis, not a law; interviewers who have read the book will be impressed that you know that.

Why "prior success" is the door for career-changers. It means evidence you have been genuinely good at something demanding — a strong degree, a sport played at a real level, running a society, hitting hard targets in another profession. The claim is that people with a pattern of achieving achieve again. Nobody is asking you to have sold before.

Extroversion: the trait everyone assumes and the data doesn't support

Adam Grant tested it directly. In Psychological Science in 2013 he measured personality in 340 outbound call-centre representatives and tracked revenue over three months. The relationship was not a straight line but an inverted U: ambiverts — people in the middle of the scale — outperformed both introverts and extraverts, averaging around $208 per hour against a study average of about $138, roughly 24% more than introverts and 32% more than extraverts.

Voice from the field

"The ambivert advantage stems from the tendency to be assertive and enthusiastic enough to persuade and close, but at the same time, listening carefully to customers and avoiding the appearance of being overly confident or excited."
— Adam Grant, quoted in ScienceDaily (2013)

The caveats again. One study, one sample, one setting — transactional outbound phone sales, not enterprise selling — with personality self-reported. Grant noted that the prior evidence for extraverts outperforming was "surprisingly weak", which is the more robust finding. The safe conclusion is not "introverts are better" but that high extraversion confers no reliable advantage, and the flexible talk-and-listen pattern does.

What helps, and what matters less than people think

Genuinely helps in this specialism: domain literacy — holding a real conversation with a lab manager or consultant radiologist without bluffing, which is why science graduates convert well; short, clear, structured writing; administrative discipline, meaning whether you update the CRM on a Friday when nobody is checking; tolerance for ambiguity, because you will routinely not know why a deal went quiet and must act anyway; and comfort being the least expert person in the room, where pretending is fatal and asking is not.

Matters less than people think: being loud, liking parties, being a "people person", natural confidence, a business degree, and the gift of the gab — fluency without substance is detected within four minutes by anyone technical.

An honest self-assessment

This is a structured reflection, not a validated instrument — there is no research-backed scoring key, and anyone selling you one is overclaiming. Rate each 1 (definitely not me) to 5 (definitely me), and for every 4 or 5, write down the evidence.

1. When someone criticises my work in front of others, my first instinct is to understand the criticism rather than defend the work.
2. I can make an unpleasant phone call I've been dreading before lunch rather than after.
3. I genuinely enjoy finding out how other people's jobs work, including budgets and approvals.
4. I have been demonstrably good at something competitive and can prove it.
5. I can write a clear, short email that gets a reply.
6. I can hold a nine-month plan in my head and act on it in week three without being reminded.
7. I can be told no ten times in a day and dial an eleventh time.
8. I could live on roughly 55–60% of my target earnings for a year without it damaging my life.
9. I am comfortable being measured, publicly and monthly, against a number.
10. I am comfortable asking directly for things — a meeting, an introduction, a decision, money.
11. I would rather be judged on outcomes than on effort.
12. There is no part of me that thinks selling is beneath me.

How to read it. Items 1, 3, 4 and 6 map onto the Roberge traits and are hardest to fake in an interview. Items 7, 8 and 9 are the ones people over-rate themselves on and later leave over. Item 12 is the quiet killer — if you privately think the work is undignified, it leaks into your voice on every call, and buyers hear it. Low scores are not disqualifying; unexamined low scores are.
