How to Interview a Salesperson
Interviewing a salesperson is uniquely tricky, because the thing you are assessing is the very thing they are best at: selling. A strong candidate will sell you on themselves brilliantly, which is exactly why so many hires look great in the room and disappoint in the role. The job of the interview is to see past the performance to the substance. This guide covers what to look for, the questions that actually reveal something, the tasks worth setting, and the red flags to watch.
What should you look for when interviewing a salesperson?
Evidence of real results, resilience, how they think about selling, and whether they listen. The polish is a given, so look underneath it.
Anyone can claim to be a top performer, so you are looking for specifics: actual numbers, real deals, a clear account of how they did it. You are also assessing temperament, because selling is a job of constant rejection, and how someone handles setbacks tells you a lot. And crucially, watch whether they listen. A salesperson who talks over you and never asks a question in the interview will do the same with your customers.
The best interview questions to ask a salesperson
Ask questions that force specifics and reveal how they actually work, not ones they can answer with rehearsed lines.
- "Walk me through your biggest deal, start to finish." Reveals whether they understand the full process or just turned up at the end.
- "Tell me about a deal you lost and why." Tests honesty and self-awareness. Anyone who has never lost is not being straight.
- "What were your numbers, and how did you compare to target?" Pushes past vague claims to actual performance.
- "How do you research and approach a new prospect?" Shows whether they have a real method or just wing it.
- "Sell me on your last company, then tell me what was hard about selling there." Tests both their pitch and their honesty.
- "What questions do you have for me?" A good salesperson is always qualifying. No real questions is a flag.
The pattern is that you want stories with specifics, not slogans. Follow up on every answer with "how" and "what exactly," because that is where the truth lives.
Should you set a roleplay or sales task?
Yes, but make it realistic. A practical task tells you far more than questions alone, as long as it reflects the actual job.
The old "sell me this pen" trick is largely theatre. Better to set a task that mirrors your real sales situation: ask them to prepare a short pitch for your actual product, role-play a discovery call, or talk through how they would approach a realistic prospect. You are not looking for a perfect performance, you are looking for how they prepare, how they ask questions, how they listen, and how they handle it when you push back. A candidate who asks smart questions before pitching is usually a better sign than one who launches straight into a polished spiel.
Red flags in a sales interview
A few warning signs reliably separate the talkers from the performers.
- All confidence, no numbers. Big claims with nothing concrete behind them.
- Blaming others for lost deals or poor results, rather than owning them.
- No clear method. If they cannot explain how they sell, they may not really know.
- Not listening. Talking over you or never asking a question mirrors how they will treat customers.
- Badmouthing past employers or customers, which says more about them than anyone else.
- Vagueness when pushed for specifics, which often means the story is thinner than it sounds.
How should you structure the interview process?
A simple, multi-stage process lets you assess different things at each step without overloading any one conversation.
A practical structure is a short initial screen to check the basics and motivation, a deeper competency interview built around the questions above, a realistic task or roleplay, and a final conversation to confirm fit and answer their questions. Reference checks at the end are worth doing properly for a sales hire, because past performance is a genuine signal. Keep the process respectful and reasonably quick, since good salespeople have options and a slow, chaotic process loses them.

Interviewing salespeople: FAQs
What questions should I ask a salesperson in an interview?
Ask for specifics: their biggest deal start to finish, a deal they lost and why, their actual numbers against target, how they approach a new prospect, and what questions they have for you. Follow up with "how" and "what exactly."
How do you tell if a salesperson is actually good?
Look for concrete evidence of results, an honest account of failures as well as wins, a clear method for how they sell, and whether they listen and ask questions rather than just pitch.
Should I make a salesperson do a roleplay?
Yes, if it is realistic. A task that mirrors your actual sales situation reveals how they prepare, question and listen. Avoid gimmicks like "sell me this pen," which test performance rather than substance.
What are the red flags when hiring a salesperson?
Big claims with no numbers, blaming others for losses, no clear sales method, not listening, badmouthing past employers, and vagueness when you ask for specifics.
Why do salespeople interview well but underperform?
Because interviewing rewards the exact skill they are strongest at: selling themselves. The fix is to push for specifics, set a realistic task, and check references, so you assess substance rather than polish.
How many interview stages should there be?
A short screen, a deeper competency interview, a realistic task or roleplay, and a final fit conversation works well. Keep it respectful and quick, as strong salespeople have options and will drop out of a slow process.
