Interviewing a Head of Growth: Questions That Reveal Real Experience
To find real experience in a Head of Growth candidate, ask for one project told start to finish and probe it until the stage, the numbers and the candidate's own role agree with everything else they said. This page gives a founder seven core questions and a consistency check, each with what a strong answer contains, what a thin one sounds like and a follow-up probe, plus a 0 to 2 scoring sheet. The questions draw on two published guides, and the rubrics are Kanso's own analysis, not tested on real interviews.
What should a founder ask a Head of Growth candidate?
Ask for one project told start to finish, then spend the rest of the interview checking that the candidate's stage, background, way of working, leadership style and numbers all agree with it. Delivering Value, a coach who says they have worked with more than 90 growth leaders, argues that each common question hides a different thing being evaluated. It adds that a story contradicting an earlier answer is a red flag candidates seldom see coming.
- Delivering Value groups the common questions into seven areas: stage fit, growth specialty, operating system, leadership style, resources and tooling, cross-functional ownership and a signature project.
- Final Round AI's list of 25 questions adds strategy, prioritisation, metrics, experimentation, churn and failure, and gives sample answers.
- Four of the sample answers that quote a percentage give no starting figure, so every number in an answer should trigger a probe.
- Each core question below has a rubric, and a 0 to 2 scoring sheet closes the page. The rubrics are our analysis.
We built the rubric in three steps. We took the seven areas from Delivering Value and its advice on what a good answer contains, added the questions and the stated purpose of each from Final Round AI's list, and then wrote what a strong answer, a thin answer and a follow-up probe look like for each. Only the first two steps rest on the sources.
If you are not yet sure that a Head of Growth is the right first senior hire, Kanso's article on when a startup should hire its first marketer covers the earlier decision.
What does a Head of Growth do, and what are you hiring them for?
A Head of Growth is responsible for expanding a company by identifying and improving growth opportunities, working with marketing, product and sales to raise acquisition, retention and revenue. That is Final Round AI's description, and it adds that the role relies on data analytics and market research.
The scope changes with company size, which matters before you interview anyone. Delivering Value says that at a 30-person startup the title can mean doing a lot of the work yourself, while at a 300-person company it can mean managing a team of eight and spending most of the time in strategic conversations.
Delivering Value also says companies usually hire to patch a specific hole, and that candidates differ by whether their roots are in growth marketing, product or data. So write a three-line brief before the first call: your stage, the hole to fill and whether the person will do the work or manage people who do. Every rubric below is scored against that brief.
If the brief shows that you need senior direction part-time, Kanso's comparison of a fractional CMO, an AI CMO and a first marketing hire sets out that alternative with costs in India.
Has the candidate worked at the stage you are in now?
The way to find out is to ask for the project that shows their best work and to listen for the environment it happened in, because most candidates will not volunteer it. Delivering Value sorts growth leaders into builders, who take a company from zero to one, optimizers, who break through a plateau, and scalers, who add new loops to a growth model that already works.
Delivering Value says none of the three is better, but that a scaler placed in a builder role, or the reverse, is one of the most common mismatches it sees. Its advice to candidates is to pick a project from the same context as the company they are interviewing for, so a founder can fairly expect that effort and check it.
Stage fit means the candidate's best work happened in a situation like yours: building from nothing, fixing a stuck system or accelerating one that works.
Question 1: stage fit
- Ask: tell me about the project that shows your best growth work, and what was already working when it started.
- Strong: names the starting situation, says whether the work was building, fixing or accelerating, and connects it to your stage or says plainly that it differs.
- Thin: lists results with no starting point, so you cannot tell what kind of work it was.
- Probe: what would you have done differently if the company had been at an earlier or a later stage?
A candidate who asks what stage you are at before answering is using the habit Delivering Value recommends to candidates. It is a good sign, and it also makes your own brief more useful to you.
Where does the candidate's growth skill come from?
It comes from one of three foundations, marketing, product or data, and the answer to a background question tells you which one. Delivering Value says a person who built their skills in growth marketing thinks differently from one who came up through product management or business intelligence, and that neither is wrong.
The same source says a specific answer beats a claim to cover everything. Its example of a strong one is a candidate who says their core skill is activation, retention and the in-product experience, and then ties that to what the company needs.
Question 2: growth background
- Ask: which part of growth did you come up through, and which part of this role would you hand to someone else first?
- Strong: names one foundation with the work that built it, states a gap without being pushed, and links the foundation to the hole in your brief.
- Thin: says they do everything, or describes a job title instead of a skill.
- Probe: give me an example where your foundation made you slower or blind to something.
How does the candidate run growth week to week?
You learn how a candidate runs growth by asking for their operating system, meaning how they structure the work, set priorities, assign ownership and decide what to track. Delivering Value calls this one of the highest-signal questions, because many candidates can talk tactics while few can describe the machine they run.
The same source gives an illustration of specificity: a weekly review of the experiment backlog, ranked by expected impact and confidence with an owner for each item, and a monthly look back at what shipped and what actually moved the metric. It contrasts that with the vague claim of running a growth meeting. Final Round AI's list asks about prioritisation under limited resources and the metrics that matter most, and its sample answers cite return on investment, acquisition cost and lifetime value in general terms.
Question 3: operating system
- Ask: walk me through last month: what did the team review, what did it decide and what did it stop?
- Strong: describes a cadence, a rule for choosing what to test, an owner per test, indicators tied to business outcomes and a review of what moved them.
- Thin: names a meeting and a list of metrics but no rule that decides between two ideas.
- Probe: show me a test you stopped early, and the rule that stopped it.
To judge the stopping rule, compare it with Kanso's guide to designing, sizing and calling a marketing test. For the metrics, Kanso's list of the weekly marketing numbers a seed-stage founder should review gives you a baseline to hear the candidate against.
Is the candidate a senior doer, a player-coach or a coach?
You can tell by asking about the last team they managed and what they did themselves, because the answer shows how they lead in practice. Delivering Value describes three styles, senior doer, player-coach and coach-first, and says the right one depends on the scope of the role.
The source tells candidates to separate what they owned directly from what they delegated, and not to pose as purely strategic if they were not. Final Round AI's list covers the same ground with a question on how the candidate builds and leads a high-performing growth team.
Question 4: leadership style
- Ask: tell me about the team you most recently managed and what you did yourself last quarter.
- Strong: gives team size and roles, splits own work from delegated work, and says how they coached people, with at least one specific example.
- Thin: recites responsibilities as they would appear in a job description, or says they set direction without saying how.
- Probe: which person on that team grew most, and what did you do that helped?
Can the candidate do more with less, using current tools?
You find out by asking what they shipped under a constraint, not what they would build with an unlimited budget. Delivering Value says candidates often describe a dream team with endless headcount, and that interviewers are really checking whether the person is resourceful or needs ideal conditions to perform.
The same source adds that interviewers expect candidates to be current, and it names AI and vibe coding tools that help design, ship and track work as the example of how tooling has moved. That is its view of what interviewers expect, not a measured fact. Final Round AI's list asks about the most effective tools and technologies, and its sample answer names Google Analytics, Mixpanel, HubSpot and Salesforce.
Question 5: resources and tools
- Ask: what is the most useful thing you shipped with less than you needed, and which tools did you run it on?
- Strong: describes one result under a stated limit, what they cut to get there, and the tools in use now with what changed for the team.
- Thin: describes an ideal team, or lists tool names with no account of what they changed.
- Probe: if I gave you half of that, what is the first thing you would stop doing?
Who owns what between growth, marketing and product?
The answer differs at every company, so ask the candidate to state a position and name an owner for each metric. Delivering Value says the edges between the three functions are messy and that a clear view of them is what interviewers want, and it names two weak answers: claiming growth owns everything, which causes conflict with peers, and deferring entirely to context, which shows no point of view.
Delivering Value offers one example of a position: growth owns the path from first visit to first value, anything before that is shared with marketing and anything after is shared with product, with a clear owner for every metric. Treat it as an illustration of the form, not the correct split for your company.
Question 6: ownership
- Ask: where does growth stop and marketing or product begin, and who owned each metric in your last company?
- Strong: states a position, names an owner per metric, and gives a real disagreement with the other team and who made the final decision.
- Thin: says it depends on the company, or that growth should own the whole funnel.
- Probe: tell me about a time a metric you owned was moved by another team's work. What happened?
How do you test the candidate's signature project?
Probe it with five questions, because Delivering Value says interviewers use the project to see whether how the candidate actually works matches everything they said earlier. The questions it lists are how the work fit company strategy, why it was prioritised over other work, how the team was structured, which tools were used and how success was defined.
- How did this project fit the company's strategy at the time?
- Why did you do it before the other things on the list?
- Who was on the team, and what did each person own?
- Which tools did you use, and what limits did you work under?
- How did you define success, and what would you do differently now?
Delivering Value suggests candidates prepare the full arc of the story, from the situation to what they would change, and that the choice of project is itself a signal. A candidate who said they thrive at zero to one and then offers a scaling project has told you something.
Question 7: the signature project
- Ask: walk me through one project from the first decision to the last number.
- Strong: answers all five probes, names a decision they would reverse, and the project fits what they said about stage, background and style.
- Thin: answers with a headline result and cannot say who did what or why this project came first.
- Probe: which part of this result would have happened without you?
How do you read the numbers in an answer?
Treat every percentage as incomplete until you know the starting figure, the period, the comparison and the candidate's own part in it. Final Round AI's sample answers show the format a candidate may rehearse: an action, a campaign, a percentage. In the extract we read, none of the four that quote one states a starting number.
| Claim in the sample answer | What is missing | Arithmetic |
|---|---|---|
| 30 percent more new user sign-ups within three months, from optimizing a referral program | The starting number, whether the comparison is to the prior period or a control, and what else changed in those three months | Hypothetical inputs, invented to show scale: 30 percent of 100 sign-ups is 30 (100 × 0.30). The same 30 percent of 10,000 sign-ups is 3,000 (10,000 × 0.30). |
| 40 percent more website traffic and a 25 percent boost in conversions, from SEO, paid search and social ads together | Whether 25 percent is conversions counted or the conversion rate, and which of the three channels did the work | If it is the rate: 1.40 × 1.25 = 1.75, so conversions rose 75 percent. If it is the count: 1.25 ÷ 1.40 = 0.893, so the conversion rate fell about 10.7 percent. |
| 50 percent more market reach, from a partnership with an industry player | What reach was counted in, over what period, and who was reached | Nothing can be calculated without a unit. Ask for one. |
| 20 percent more engagement after fixing a product bug that had caused a significant drop | The size of the drop, the engagement measure, and whether the 20 percent is measured from before the bug or from the dip | Hypothetical drop, invented to show the effect: if the bug cut engagement by 20 percent, 0.80 × 1.20 = 0.96, which is still 4 percent below where it began. |
The second row is the useful one. The same sentence can describe a 75 percent rise in conversions or a falling conversion rate, and only a probe tells you which. The general rule is below.
result = (new value ÷ old value) − 1, so ask for the old value, the period and the comparison before you accept the percentage
Which other questions from the common lists are worth asking?
Four questions from Final Round AI's list of 25 are worth adding because they test things the core questions do not: changing course, building an experiment habit, retention and handling a hard problem. The table gives the purpose the list states for each and our rubric.
| Question | What the list says it tests | Strong answer contains | Thin answer |
|---|---|---|---|
| Tell me about a time you changed your growth strategy and what made you change it (item 8 on the list) | Final Round AI: adaptability and decision-making in changing conditions | Names the signal that forced the change, such as diminishing returns on a channel (the list's own sample answer moves from paid ads to content for that reason), says what was given up, and gives the period it took | Presents the change as planned from the start, or names no signal |
| How do you build a culture of experimentation in your team? (item 11) | Final Round AI: whether the candidate can create an environment where new ideas are valued and tested | Describes mechanisms: a backlog, a review cadence, a rule for stopping a test, who may start one | Describes values only, such as open communication and celebrating failures |
| What do you do to keep customers and reduce churn? (item 14) | Final Round AI: keeping a loyal customer base, which it ties to sustainable growth | Says where in the customer lifecycle they looked, how they found the cause in churn data, and which change they tested | Names personalised engagement and loyalty programmes with no cause found and no result |
| Describe a hard growth obstacle and how you overcame it (item 16) | Final Round AI: problem-solving and resilience in overcoming significant challenges | A problem the candidate helped cause or misjudged, their own share stated, and the rule or habit they changed afterwards | A problem caused by others, or a success dressed as a setback |
We left out the rest of the 25 on purpose. Some, such as how a candidate stays up to date with trends, produce an answer a candidate can rehearse without having done anything, and the list's own sample answer for that one is a general description of newsletters and conferences.
How do you score a Head of Growth interview?
Score each core answer from 0 to 2 against fixed anchors, add the eight scores for a total out of 16, and use the total to decide where to probe next, not as a pass mark. The seven questions above are rows one to seven, and the eighth row scores consistency across the whole conversation.
| Question | What it tests | 0 | 1 | 2 |
|---|---|---|---|---|
| 1. Stage fit | Which environment the candidate does their best work in | Results with no starting point | A starting point is named, but the stage differs from yours and it is not acknowledged | Starting point named, builder, optimizer or scaler work identified, and it matches your stage or the gap is acknowledged |
| 2. Background | Where the candidate's skill comes from | Claims to cover everything | Names a foundation but not what they have not done | Names a foundation with the work that built it, states a gap, and ties it to your hole |
| 3. Operating system | Whether there is a repeatable way of working | A meeting name and a metric list | A cadence is described but no prioritisation or stopping rule | Cadence, prioritisation rule, an owner per test, a review of what moved the metric, and a test they stopped |
| 4. Resources and tools | Resourcefulness and currency | A dream team, or a list of tool names | Something shipped under a limit, but no current tools or no cut named | Something shipped under a limit, what was cut, and current tools with what changed for the team |
| 5. Leadership | The real scope of the last role | Responsibilities as on paper | Team size and roles, but no split between own work and delegated work | Team size, roles, own work against delegated work, and how they coached |
| 6. Ownership | A position on boundaries | Growth owns everything, or it depends | A position with no named owner per metric | A position, a named owner per metric, and a real disagreement and who decided it |
| 7. Signature project | Whether the story holds under probing | Cannot answer two of the five probes | Answers all five, but the project fits none of the earlier answers | Answers all five, names what they would change, and fits the earlier answers |
| 8. Consistency across the interview | Whether answers agree with each other | A direct contradiction | A tension the candidate cannot explain | No contradictions, and the candidate raises and resolves any tension themselves |
Consistency gets its own row because Delivering Value treats a contradiction between a story and an earlier answer as a red flag. Mark the contradicting answer down when it appears, instead of noting it and moving on.
We give no pass mark because no source supplies one and we have not tested these anchors. To calibrate, have two people score the same recorded interview separately and compare where they differ. Where they differ, rewrite the anchor.
The red flags the sources describe, plus two we add:
- A story that contradicts an earlier answer (Delivering Value).
- Claiming growth owns everything, or deferring entirely to context (Delivering Value).
- Describing an ideal team with unlimited resources and nothing shipped under a limit (Delivering Value).
- Our addition: a percentage with no starting figure, period or comparison.
- Our addition: a best project from a stage very different from yours, with no acknowledgement of it.
What is documented and what is our analysis?
The first list holds what the two sources state, and the second holds Kanso's interpretation. Keep them apart when you weigh the rubric.
- Documented: Delivering Value says common questions cover seven areas and that each hides a different thing being evaluated.
- Documented: Delivering Value describes builder, optimizer and scaler profiles, three leadership styles, and weak ownership answers.
- Documented: Delivering Value says interviewers probe a project for strategy fit, prioritisation, team structure, tools and success definition.
- Documented: Final Round AI lists 25 questions, gives a stated purpose and a sample answer for each of those we quote, and its sample answers include the percentages in the table.
- Analysis: the strong, thin and probe wording for every question, the 0 to 2 anchors and the total out of 16 are ours.
- Analysis: the arithmetic on the sample answers and its hypothetical inputs are ours, and show why a base is needed.
- Analysis: the two red flags marked as additions and the reading of the growth marketer interview are ours.
- Gap: both sources are practitioner or vendor content, and neither is a study of what predicts a successful hire.
- Gap: the sources give no pass mark, no reference-check method and no data on how long these interviews run.
Head of growth interview: frequently asked questions
What does a Head of Growth do?
A Head of Growth drives a company's expansion by finding and improving growth opportunities, and works with marketing, product and sales to raise acquisition, retention and revenue. That is Final Round AI's description, which adds that the role relies on data analytics and market research. Delivering Value notes that the scope varies a lot by company size, from doing much of the work yourself at a 30-person startup to managing a team of eight at a 300-person one.
What sort of questions will a Head of Growth interview include?
Expect questions on stage fit, growth specialty, operating system, leadership style, tools, cross-functional ownership and a signature project. Delivering Value names those seven areas, and Final Round AI's list of 25 adds strategy, prioritisation, metrics, customer feedback, experimentation, churn and failure. This page turns eight of them into questions a founder can ask, with a rubric for each answer.
What is an interviewer really asking with: how would you describe your growth background?
The interviewer is placing the candidate on the marketing, product or data side of growth and checking that it matches the gap in the role. Delivering Value says the three backgrounds think differently and that companies usually hire to fill one specific hole. A strong answer names one foundation, is honest about it and links it to what the company needs.
How do you define what growth owns and what marketing or product owns?
There is no single correct line, and Delivering Value says every company draws it differently. What a founder should listen for is a stated position with a named owner for each metric, such as growth owning the path from first visit to first value, shared with marketing before that point and with product after it. That example is Delivering Value's, offered as an illustration, not a standard.
Is a growth marketer interview different from a Head of Growth interview?
Yes, mainly in scope and in how much you test hands-on channel work against leadership. Neither source we read compares the two directly, so this is our reading: a growth marketer interview should weight a worked example of channel execution and measurement, while a Head of Growth interview adds operating system, team, ownership boundaries and stage fit. The seven core questions on this page still work as a base for both, with questions 4 and 5 weighted less for an individual contributor.
What strategic and leadership questions tend to come up at this level?
The common ones ask about the team the candidate most recently managed, their ideal team, how they define ownership between growth and other teams, and how they build and lead a high-performing growth team. Delivering Value reads the team questions as a test of leadership style: senior doer, player-coach or coach-first. Final Round AI's list adds aligning growth with the company vision, scaling a business and balancing short-term and long-term goals.
What are the red flags in a Head of Growth interview?
The clearest red flag in the sources is a story that contradicts something the candidate said earlier, which Delivering Value says candidates rarely expect. It also describes two weak answers on ownership, claiming growth owns everything or deferring entirely to context, and a team answer built on an unlimited budget. Our additions are percentages with no starting figure and a best project from a stage unlike yours.
Which metrics should a Head of Growth name as most important?
No source we read gives a required list, and the right metrics depend on the business. Delivering Value says to listen for key performance indicators tied to real business outcomes, and Final Round AI's sample answer names customer acquisition cost and lifetime value. Judge the candidate on whether they can say how each metric was measured and what decision it changed.
How can you check that a candidate's growth results are real?
Ask for the starting figure, the period, the comparison and the candidate's own part in every result, then check the details of the story against each other. Delivering Value recommends probing strategy fit, prioritisation, team structure, tools and the definition of success. The sources we read describe no other verification method, so any step beyond probing is your own addition.
How should a candidate prepare for these questions?
A candidate should work out which stage the company is in, then pick projects from a similar setting and describe their working rhythm in concrete terms. Delivering Value advises preparing the full arc of one project: the situation, the decisions, the team, the tools and constraints, how success was measured and what they would change. It also says candidates should ask about the company's specific gap before answering.
