What's the biggest mistake people make when hiring sales reps?

Hiring on interview performance. A great interview measures one thing — how well someone performs a high-stakes conversation they prepared for. It tells you almost nothing about whether they'll run a consistent day, recover from rejection, or hold a number across a bad month. Charisma in a room is not durability on a floor.

What actually predicts whether a sales hire will succeed?

Evidence of consistency and structure in how they already run their life and work — not peak performance, but baseline reliability. Look for a track record of steady output over time, honest self-assessment, coachability, and how they describe handling a bad stretch. Those signals predict durability. A polished pitch doesn't.

Should I hire experienced sales reps or coachable ones?

Coachable beats experienced if you have a real onboarding system, because experience often comes with entrenched habits you'll have to undo. If you have no system and need someone to produce immediately, experience matters more — but you're also more likely to inherit someone else's plateau. The best hires are coachable people who'll adopt your structure.

How do you screen for consistency in a sales interview?

Ask about the boring stretches, not the highlights. 'Walk me through a month where nothing was working — what did your days look like?' Reliable reps describe a structure they kept running anyway. Volatile reps describe waiting for momentum to come back. Also ask how they currently organize their day; vague answers are a red flag.

Why do strong-interviewing sales hires often underperform?

Because the interview rewards exactly the trait that doesn't predict the job: peak performance in a prepared, high-stakes moment. The job rewards baseline performance in an unprepared, repetitive, often demoralizing grind. Those are different skills. People who are great at the first and shaky at the second interview brilliantly and then can't hold a number.

Why Most Sales Hiring Is Broken — and What I Look For Instead

Hiring sales reps on charisma and a strong interview is how you build a volatile team. After a decade of running floors, here's what actually predicts who holds a number — and what doesn't.

Most sales hiring is broken because it measures the wrong thing. The interview rewards peak performance in a prepared, high-stakes conversation — and the job rewards baseline performance in an unprepared, repetitive, frequently demoralizing grind. Those are not the same skill, and hiring for the first while needing the second is how you end up with a team full of people who interviewed brilliantly and can’t hold a number. After a decade of running floors and making plenty of these mistakes myself, what I look for now is evidence of consistency and structure — not charisma, not a polished pitch, not a great story about their best month. Durability, not peak.

What the Standard Process Actually Measures

Walk through how sales reps usually get hired. There’s a resume screen, a couple of conversations, maybe a role-play, and a gut call on “can this person sell.” The person who advances is the one who’s warm, articulate, quick on their feet, has a compelling narrative, and handles the role-play smoothly.

Here’s the problem: every one of those signals measures the same thing — how well someone performs a single high-stakes interaction they had time to prepare for. That’s a real skill. It’s also almost completely orthogonal to the job, which is not “perform brilliantly once” but “show up Monday through Friday, run the same blocks, eat thirty rejections a day, lose a deal you thought was closed, and produce a steady number anyway — for a year, for two years, for five.”

The interview is a sprint with a warm-up. The job is a marathon with no finish line and bad weather. We keep timing the sprint and being surprised when the hire can’t run the marathon.

Why the Charismatic Hire Disappoints So Often

I’ve made this hire more times than I’d like to admit. The candidate is magnetic. The room lights up. They have an answer for everything. You think: this person is a closer. You hire them, and three months later they’re middle of the pack at best and you can’t figure out why.

Here’s why. Charisma is a peak-state ability. It shows up when someone is energized, prepared, performing. The job is mostly not a peak state — it’s a grind state, a depleted state, a “third dead lead in a row on a Tuesday afternoon” state. And in that state, charisma does nothing, because there’s no audience and no adrenaline. What carries you through the grind state is structure: a day that runs whether you feel like it or not, a recovery system that keeps you off the floor, mechanical resets that keep rejection from compounding. The charismatic hire often has none of that — they got by on the spike, never had to build the floor, and now there’s no spike and no floor.

This tracks with what the research says about predicting job performance. The work on structured behavioral interviewing consistently finds that asking people to describe how they actually handled specific past situations predicts performance far better than gut impressions of how someone “comes across.” We keep relying on the gut impression because it’s fast and it feels insightful. It mostly just measures likeability.

What I Look For Instead

I’m trying to find evidence of durability — a baseline that holds under conditions the job will absolutely throw at this person. A few things actually carry signal:

A track record of steady output, not a highlight reel

I don’t care about their best month. Anyone can have a best month. I want to know what their median month looked like, and how wide the gap was between their good months and their bad ones. A rep who did $14K, $13K, $15K, $12K is a more interesting hire than one who did $30K, $8K, $25K, $9K — the second one has a higher ceiling and a much shakier floor, and the floor is what I’m buying.

How they describe a bad stretch

This is the most useful question I ask: “Walk me through a month where nothing was working. What did your days actually look like?” The durable candidate describes a structure they kept running anyway — “I held my morning block, I just kept dialing, I knew it’d turn.” The volatile candidate describes waiting — “I kind of lost momentum, I was trying to get my head right, it eventually came back.” The first answer is someone with a floor. The second is someone who has spikes and gaps. The job will give them a lot of bad stretches. I need to know which mode they default to.

How they currently run a day

“Tell me how you organize a normal workday.” If the answer is specific — protected blocks, a follow-up rhythm, a wrap-up routine — that’s a person who’s already built something I can build on. If the answer is vague — “I kind of go with the flow, see what’s urgent” — that’s a person whose income tracks their mood, and no comp plan fixes that. It’s not disqualifying, but it tells me exactly what onboarding has to do.

Coachability over raw experience

If I have a real onboarding system — and you should — I’d rather hire a coachable person with less experience than a veteran with entrenched habits I’ll have to surgically remove. Experience often means I’m inheriting someone else’s plateau and someone else’s bad structure. A coachable rep who’ll actually adopt the operating system we install outperforms a stubborn veteran inside two quarters. The exception: if you have no onboarding system and need production immediately, experience matters more — but then you’ve also accepted you’re hiring a finished product, flaws and all.

The Honest Caveat

None of this means charisma is bad or experience is worthless. A warm, articulate, experienced rep with a solid floor is the best hire there is. The point is that you can’t substitute the interview signals for the durability signals. Lots of charismatic people have shaky floors. Lots of experienced people are carrying bad habits. The interview tells you they can perform once. It doesn’t tell you they can perform two hundred times in a row, and the second thing is the job.

It also means: if your hire does come in with a shaky floor, that’s not necessarily a firing offense — it’s an onboarding problem. A rep who runs on mood can be rebuilt to run on structure. But you have to know that’s what you bought, and you have to have the system to do the rebuilding. Hiring someone with no floor and no plan to build them one is just hoping. Hope isn’t a staffing strategy.

What This Comes Down To

Stop hiring the best interview. Start hiring the most durable operator — the person whose worst month doesn’t fall off a cliff, who describes a bad stretch in terms of a structure they held, who can already tell you how their day is built, and who’ll actually adopt yours. That person is less impressive in a room. They’re far more valuable on a floor. I learned that the expensive way, by hiring the impressive one too many times.

If you’re building a team and you’re tired of the spike-and-crash hires — or you’re the rep who interviews great and can’t hold a number — the fix is the same in both directions: build the floor. See what that rebuild looks like, or read what actually makes a rep consistent.
