30 growth marketer
interview questions that actually work.
Pulled from the Neuroworx item bank: nine years of calibration against twelve-month performance outcomes on 14,083 growth marketers. Sorted by stage (screen, assessment, on-site) and level (IC1 to IC5). Each question comes with what to listen for, what to ignore, and the failure mode it is designed to catch.

Stage 01 · Screen
Twelve minutes. Ten questions.
The screening conversation. Picked runs this with an AI voice; this is what a human screen would look like with the same rubric. Time-box hard. 60 seconds per answer.
10 questions
01
Walk me through the last growth experiment you ran end-to-end.
scopespecificity
Listen for
A specific hypothesis, a specific test design, the read. What they did with the loser.
Ignore
A list of tactics. We want the experiment shape.
catches · Candidates who can talk launches but not learnings.
02
Tell me about a funnel diagnosis you did that surprised you.
funnel instinct
Listen for
A specific step. The cohort cut that revealed it. What they did next.
Ignore
A surface-level "the activation step was weak" answer.
catches · Candidates who treat the funnel as a single number.
03
Describe a referral or growth loop you killed.
judgementhonesty
Listen for
A specific loop. The retention or unit-economic reason. The conversation with the lead.
Ignore
"We always look at retention." Generic.
catches · Candidates who never kill a loop that hits headline numbers.
04
When did you last co-write a spec with engineering?
cross-functional
Listen for
A specific feature. The shape of the back-and-forth. The thing they conceded.
Ignore
"I work closely with engineering." Vague.
catches · Candidates who throw briefs over the wall.
05
Tell me about an experiment you designed not to run.
experiment design
Listen for
A specific idea. The reason the test would not have read. What they did instead.
Ignore
"I run lots of experiments." Misses the question.
catches · Candidates who run tests without a sample-size calculation.
06
Walk me through how you would diagnose a sudden drop in week-2 retention.
operatingfunnel
Listen for
A sequence. Cohort cut by acquisition channel, by sign-up path, by feature usage, by onboarding variant. They name the cheapest check first.
Ignore
"I would check the data." Vague.
catches · Candidates who blame the product without a cut.
07
What is the most engineering-literate thing you have done?
engineering literacy
Listen for
A specific event spec, a SQL refactor, a deploy they shipped. They can read the schema.
Ignore
"I work well with engineering."
catches · Candidates who outsource every instrumentation question.
08
Tell me about the last time the holdout disagreed with the dashboard.
honesty about lift
Listen for
A real moment. The decision they made. The conversation with leadership.
Ignore
"We trust the holdout." Without a story.
catches · Candidates who never run holdouts.
09
How do you onboard onto a new growth org?
generality
Listen for
A sequence. Read the last six experiment reads, find the deepest funnel cut, sit with the engineer who owns the event spec.
Ignore
"I read the docs first."
catches · Candidates who freeze without a playbook.
10
One thing you want from the next role you would not have applied for if not.
stage fit
Listen for
A specific something. A specific product surface. A specific stage.
Ignore
"Impact." Vague.
catches · Candidates unsure why they are looking.
Stage 02 · Role-fit assessment
A scoped task. A scored rubric.
One scoped exercise. We score the thinking, not the polish. The candidate has the equivalent of 45 minutes.
8 questions
01
Here is a one-paragraph product context. Identify the funnel step you would attack first and write the hypothesis in three sentences.
funnel instinctIC2+
Listen for
A specific step. A hypothesis tied to a behaviour. A read criterion that is not just lift on the next step.
Ignore
A blanket "improve activation" answer.
catches · Candidates who attack the loudest step, not the leakiest.
02
Design the experiment for the hypothesis in question 1. Sample, duration, success metric, guardrail metric. 200 words max.
experiment designIC2+
Listen for
A sample-size calculation that is not hand-waved. A guardrail metric. A duration that respects weekly seasonality.
Ignore
A test that lasts a week and reads on a flash-sale weekend.
catches · Candidates who design tests they cannot read.
03
Here is a real experiment read with a positive lift on the success metric and a negative lift on a guardrail. Recommend in 200 words.
honesty about liftIC3+
Listen for
A recommendation that takes the guardrail seriously. They will not ship.
Ignore
A recommendation that ships and "monitors".
catches · Candidates who optimise for the success metric alone.
04
Co-write the engineering spec for a growth loop with this product manager brief. Three sections: instrumentation, surface, eligibility. 300 words.
cross-functionalengineering literacyIC3+
Listen for
A real spec. The instrumentation comes first. The eligibility rules avoid the obvious abuse.
Ignore
A spec that hands the work to engineering.
catches · Candidates who cannot write a spec engineering will read.
05
A senior leader wants to launch a referral programme by next quarter. Make the case for delay in 100 words.
stakeholder managementIC2+
Listen for
A real case. The retention work that should come first. They will say no.
Ignore
A pure yes.
catches · Candidates who say yes to every growth idea.
06
Diagnose this real funnel chart in 200 words.
funnel instinctIC2+
Listen for
A real diagnosis. They name the step, the cohort cut they would run next, the hypothesis they would test.
Ignore
"Activation is weak." Without a cut.
catches · Candidates who diagnose without a cut.
07
Write the email you would send to the CEO the week your big experiment failed.
commshonesty about lift
Listen for
An email that owns the result. A real learning. A specific next step.
Ignore
An email that hedges or blames the test design.
catches · Candidates who hide failed reads.
08
In 200 words: why might the experiment you designed in question 2 read flat even if the hypothesis is right?
humilityIC3+
Listen for
A real engagement with confounders. The cohort the test will not reach. The metric the test will not move yet.
Ignore
A second pitch for the original design.
catches · Candidates who cannot question their own test.
Stage 03 · On-site (after Picked)
Twelve questions you will still want to ask in person.
Picked screens, scores, and shortlists. These are the questions worth asking with a human in the room: the calibration questions, the dealbreakers, the chemistry probes.
12 questions
01
Where, in growth, do you want to grow most this year?
growth
Listen for
A specific gap. A plan. A name of someone they would learn from.

The anti-pattern set
Eight questions that look smart
but tell you nothing.
"What is your biggest weakness?"
You will get a strength-shaped weakness. We have asked this 47,000 times. It catches no-one. Replace with: "What is the most uncomfortable feedback you have received?".
"Where do you see yourself in five years?"
Either a rehearsed answer or a stalled one. Both useless. Replace with: "Where would you want to be in three years?"
"Tell me about yourself."
Wastes the first three minutes on the CV they already gave you. Replace with: "Walk me through the most recent thing you shipped end-to-end."
"Why this company?"
Generates polished mission-talk. Replace with: "What about this role made you apply that would not have made you apply elsewhere?"
"Are you a team player?"
No-one says no. Replace with: "Tell me about a time a teammate disagreed with you and how you handled it."
"How do you handle stress?"
No-one says badly. Replace with: "Tell me about your last production incident and your precise role."
"How would you reverse a linked list?"
Probes nothing we care about. We removed it from the bank in 2019. Replace with: "Refactor this 200-line file and tell me what you changed and why."
"If you were an animal, which animal would you be?"
You know what we are going to say. Replace with: anything else.
Or, let us ask
We will ask these for you.
