What Two Years of Cold-Calling Taught Me About Reading a Résumé
Nobody's CV lists the skill that actually got them promoted.
In 2011 I spent two years cold-calling for a telecoms reseller out of a business park near Reading, and by the end of it my CV said exactly what everyone else's said: job title, dates, one line about exceeding targets. It told a hiring manager nothing about the thing that actually got me promoted twice in eighteen months, which was that I'd rewritten my own discovery questions eleven times, timed my call recordings against the month before, and could tell you precisely which objection response converted and which one just made prospects go quiet and hang up. None of that fits in a CV bullet. Fifteen years, two founder stints and three CCO jobs later, I still haven't seen a résumé that captures it — and I've stopped expecting one to.
Here's what's strange about that, given how much weight we put on the document. Every hiring process I've run or sat inside treats the CV as the primary filter: title progression, tenure, a quota badge if you're lucky enough to have one that means anything. And every one of those three things is close to useless as a predictor, for reasons that have nothing to do with the candidate lying and everything to do with what a CV is structurally capable of recording.
The bullet points everyone trusts
Take the three line items hiring managers lean on hardest, and look at what they actually tell you.
| CV signal | What it seems to say | What it actually tells you |
|---|---|---|
| Job title ("Senior AE", "Enterprise BDR") | Seniority, scope, capability | Almost nothing — titles are inflated inconsistently across companies, and a title tells you what someone was called, not what they could do |
| Tenure ("3 years at X") | Stability, competence, trust from the employer | Could mean genuine growth, could mean nobody got around to performance-managing them out, could mean the market was soft and they had nowhere better to go |
| Quota attainment ("127% of quota") | Sales ability | Depends entirely on territory quality, quota-setting rigour, product-market fit, and how many deals a manager helped close personally — none of which appears anywhere near the number |
I don't say this to be cynical about candidates. I say it because I've hired against all three signals and been wrong in both directions — passed on people who turned out excellent, hired people whose CVs were immaculate and who couldn't run a discovery call without a script taped to their monitor. The document is optimised for pattern-matching, not for truth.
What actually predicts performance
The thing that has correlated, reliably, across every hire I've made or watched made well, is evidence of deliberate, repeated skill-building — and it is structurally invisible on paper. It doesn't show up as a line item because it isn't an event, it's a habit: someone who reviewed their own calls without being told to, who could name the specific competency they were weakest on eighteen months ago and describe exactly what they changed to fix it, who treats a bad month as a diagnostic problem rather than a run of luck.
That's not a soft skill and it isn't charisma. It's the same instinct that separates a hobbyist musician from a working one: not the number of gigs, but the number of hours spent on the unglamorous, repeated correction of a specific weakness. On a CV, a rep who spent two years running one script on autopilot and a rep who spent two years systematically rebuilding their discovery questioning look identical. Same title, same tenure, similar quota number. Only one of them is worth betting a territory on.
The tell is in the follow-up question
So where does this show up, if not on paper? In conversation, and only if you ask the right follow-up. "Walk me through your best deal" gets you a story. "Walk me through what you changed about how you ran discovery calls between your first quarter and your best quarter" gets you either a specific, textured answer — a competency named, a moment they realised it wasn't working, a concrete change, a result — or it gets you silence, deflection, or a generic "I just got more confident." That gap is the entire signal. It costs one extra question and most interviews never ask it.
This is really the same discipline as a good reference check, just moved earlier in the process: you're not confirming what's on the page, you're testing whether there's substance behind it. If you're building or tightening a hiring process around this, a structured framework beats winging it — the Sales Candidate Scorecard: The 7-Competency Hiring Rubric forces the conversation onto named competencies rather than vibes, and a Reference Check Script for Sales Hires closes the loop by putting the same specific question to the people who watched the work happen.
Building the evidence yourself
If you're a rep reading this rather than a manager, the practical implication runs the other way. Your CV was never going to carry this information, so stop trying to cram it in as another bullet point and start building the paper trail somewhere else — a running record of which specific skill you were working on each quarter, what changed, what the result was. Not a highlight reel. A development log. When it comes time to interview, you'll have the textured answer ready instead of reaching for one on the spot, and you'll also have done something more useful than impressing a hiring panel: you'll have actually gotten better, on purpose, instead of by accident. A structured Individual Development Plan (IDP) Template for Sales Reps does this job better than a notes app, mostly because it forces you to name the skill instead of describing the deal.
Two years of cold-calling didn't teach me to write a better CV. It taught me the CV was never the point. The two reps who got promoted alongside me weren't the ones with the best quota line — quota depended on territory, and territory was arbitrary. They were the ones who could tell you, unprompted, exactly what they'd changed about how they opened a call, and why. That's still the only résumé line that's ever told me the truth.
