How to Run a Mock Sales Call in an Interview

A mock sales call is a short roleplay where a candidate runs a cold call or discovery call against an interviewer playing the prospect, scored against a fixed rubric. It's the closest thing to a work sample you can run in an interview, and it tells you far more than asking someone to describe how they'd handle an objection. Done well, it takes 15 minutes and surfaces exactly the behaviors that separate closers from order-takers.

This is the step-by-step: the brief, the prospect sheet, the rubric, and what to actually grade.

Why run a mock sales call instead of just asking questions?

Because asking "how would you handle a pricing objection?" tests how well someone talks about selling. A mock call tests whether they can do it live, when the prospect goes off-script and they have to think.

This isn't just intuition. The strongest research on hiring, Schmidt and Hunter's 1998 meta-analysis of selection methods, found work-sample tests among the most predictive ways to evaluate candidates, well ahead of unstructured interviews. A mock call is a work sample for selling. You're watching the actual job, in miniature, instead of grading a story about it.

Step 1: Write the brief

Give the candidate the scenario in advance, usually 24 to 48 hours. Withholding it tests improvisation, but it also tests anxiety, and you want to see their selling, not their nerves. A short brief levels the field.

The brief should name: the product they're selling (yours, or a simple stand-in), the call type (cold outbound vs. inbound discovery), the goal of the call (book a next step, qualify, uncover pain), and how long it'll run. Keep it to half a page. You're setting the scene, not writing a case study.

Step 2: Build the prospect sheet

This is the part most interviewers skip, and it's why their roleplays feel fake. The interviewer playing the prospect needs a consistent character, so every candidate faces the same buyer.

Write a one-page prospect sheet the candidate never sees:

• Who you are: role, company, what you care about.
• Your situation: the actual problem, which the candidate has to uncover, not be handed.
• Your objections: two or three you'll raise, with the order and the trigger ("if they pitch before asking anything, push back on relevance").
• What earns the next step: the specific thing a good rep would have to do to get you to say yes.

The sheet keeps the roleplay fair and repeatable. Without it, you unconsciously give the candidates you like an easier buyer.

Step 3: Define the scoring rubric before the call

Decide what good looks like before anyone talks, or you'll grade on vibes. Use a weighted rubric with a 1-5 scale and behavioral anchors, the same discipline you'd use on a hiring scorecard.

Weight discovery and objection handling the heaviest. Those are the behaviors that most separate reps who close from reps who don't, and they're the hardest to fake.

Step 4: What should I grade during the mock call?

Watch behavior, not polish. Three patterns tell you the most.

Does the candidate ask or pitch? Count the genuine questions in the first few minutes. Order-takers pitch immediately; closers get the buyer talking. Does the candidate stay composed when you push back, or do they get rattled and concede? And do they drive to a next step, or let the call drift to a polite goodbye?

Score immediately after the call, while it's fresh, and against the rubric you wrote, not against the candidate you've already decided you like.

How do I keep mock calls fair across candidates?

Consistency is the whole game. Same brief, same prospect sheet, same interviewer playing the prospect when you can, same rubric. The point of the structure is to remove the interviewer's mood and bias from the score, so the candidate who actually sells best comes out on top, not the one who's most like you.

The flip side: mock calls are interviewer-heavy. They take prep, a trained roleplayer, and disciplined scoring, and they still only show one call. One call is a hint; several calls is a read. That's the limit of any single roleplay. The spread it's trying to catch is real: across 2,420 meetings in the MedLeague case study, reps on the same leads closed anywhere from 60.9% down to 30.6%, and a single mock call won't always tell you which kind you're talking to.

This is where scoring real calls complements the mock. Salescadia Scout builds a candidate's Compass Score from their actual past calls, or a short AI interview that runs like a live one, scored on the same behaviors your rubric grades: discovery, composure, objection handling, and selling style. Every score points to the moment that earned it, and a confidence band tightens as more calls come in. Use the mock to see a candidate live, and the Compass Score to check whether that one call was typical. One honest note: the score measures how someone sells, it doesn't promise the hire works out. It just makes the "can they actually sell" question answerable from evidence.

Key takeaways

• A mock sales call is a work sample, the most predictive interview format research has found, and far better than asking candidates to describe how they'd sell.
• Run it in four steps: a short brief shared in advance, a one-page prospect sheet the candidate never sees, a weighted rubric written before the call, and disciplined scoring right after.
• Grade behavior over polish: ask vs. pitch, composure under pushback, and whether they drive to a next step.
• Keep it fair with the same brief, prospect, and rubric for everyone, and have two people grade to calibrate.
• One call is a hint. Pair the mock with a Compass Score from real calls to see whether it was typical, and remember the score measures selling behavior, not hire success.
