Key takeaways
- Behind every question there is one thing the interviewer wants to assess: commercial judgement, honesty, collaboration or the ability to summarise. Answer that.
- A strong marketing answer ends in a business outcome (sales, acquisition cost, retention), not in an activity such as “we launched a campaign”.
- Six well prepared STAR stories, each with its own number, will cover most of an interview.
- Questions about AI and about measuring with less tracking data are now routine: bring one concrete example for each.
- Researching the company's current marketing (its ads, its website, its tone of voice) is what sets a candidate apart more than anything else.
What each question is really assessing
Whoever is interviewing for a marketing role has little time and plenty of doubts: can you prioritise, are you comfortable with numbers, will you clash with the sales team, are you describing what you did or what your team did. Each question is an indirect way of settling one of those doubts.
That is why the same answer can be good or bad depending on the question. Describing a brilliant campaign in detail does not help if you were asked how you decide where the money goes. This table sums up the questions that come back again and again, what they are looking for and what your answer must include.
| Question | What they are really assessing | What a strong answer includes |
|---|---|---|
| “Tell me about yourself” | Ability to summarise and fit with the role | Ninety seconds: what you do now, one achievement with a figure and why this role |
| “How would you approach your first 90 days?” | Whether you listen before acting | A diagnosis using data, customers and the team; then priorities and a first measurable win |
| “How do you decide which channels to invest in?” | Commercial judgement | Acquisition cost, customer value, payback period and a small test before scaling |
| “Which metrics do you check every week?” | Whether you separate business results from activity | Three or four business metrics and what you do when one of them moves |
| “Tell me about a campaign that did not work” | Honesty and ability to learn | The signal that warned you, what you stopped, what it cost and what you changed afterwards |
| “What budget have you managed?” | Scale and real accountability | Amount, period, who signed it off and how you split the money |
| “How do you work with sales?” | Cross-team collaboration | A shared definition of a qualified lead, a regular meeting and a common dashboard |
| “What do you think of our marketing?” | Preparation and judgement | Something specific you saw, what works and an improvement idea put forward with care |
How to answer: STAR without sounding scripted
STAR stands for Situation, Task, Action and Result. It keeps you from rambling: two sentences of context, one on what had to be achieved, three or four on what you did (not the team) and the number at the end. What does not work is reciting it like a template; interviewers spot a memorised answer straight away.
The most common mistake in marketing is stopping at the action and never reaching the result. “We ran a social campaign” says nothing; “orders from new customers rose by 18% in eight weeks” does. And if the result was poor, you still say so, together with what you learnt. This is what a complete answer sounds like:
Situation: “I led acquisition at Northside Coffee, an online speciality coffee shop based in Leeds. In spring 2025, our cost per order on Meta went from £16 to £27 in six weeks, just before our busiest season.”
Task: “I had to get back to roughly £17 per order without losing volume, and explain it to the leadership team with data rather than gut feeling.”
Action: “I split the results between new and returning customers and found that almost half the budget was going on people who would have bought anyway. I excluded anyone who had ordered in the last 180 days, moved a quarter of the spend to Google search and tested three ads filmed by real customers against our studio ones.”
Result: “Within eight weeks, cost per order was down to £18 and orders from new customers were up 18%. Since then I check cost per order every week, split between new and returning, because the blended figure had hidden the problem from me.”
Why it works: it owns the failure without blaming anyone, shows reasoning backed by data, says what the person personally did and ends with a lesson that changed how they work. It takes under two minutes.
Strategy questions
- “What would you do if you had to grow 30% next year?” Do your homework first: who their customers are, how they sell today and which channel looks under-used. Talk about hypotheses you would test, not certainties.
- “How would you position our product against the competition?” Name two or three real competitors, what each one promises and where the gap is. Show you looked at the market before walking in.
- “How would you launch something new on a very small budget?” Prioritise: one audience, one message, one or two channels and one metric to decide whether to carry on. A few things measured properly beat many done halfway.
Metrics and budget questions
- “Leads are down 25% this month. What do you look at first?” Walk through the funnel in order: traffic, landing page conversion, form quality, tracking changes. What they are assessing is your method for finding the cause.
- “How do you measure a brand campaign?” Separate what can be attributed from what cannot: branded searches, direct traffic, recall in surveys, and a comparison between regions or periods with and without the campaign.
- “If your budget were cut by 20%, what would you cut first?” Whatever has the worst marginal return, not whatever you like least. Explain how you would know and what you would keep an eye on after the cut.
Questions about your team and other departments
- “How do you handle someone in your team who is underperforming?” Clear expectations, regular check-ins, practical support and a date to review. Avoid both extremes: neither “I had a word and that was it” nor “I took them off the project”.
- “How would you make your first hire?” Which gap it fills, what you would do yourself in the meantime and how you would judge after six months whether the hire worked.
- “Tell me about a disagreement with product or with senior leadership.” Pick a real one where you argued your case with data and accepted the final decision. Show you can disagree without damaging the relationship.
The newer questions: AI and measuring with less data
Questions that hardly came up a few years ago are now increasingly common. They are not checking whether you are an expert in everything, but whether you have your own judgement and a real example.
- “How do you use AI in your work?” Describe one concrete use (first drafts of ads, analysing customer reviews, variants for testing) and how you check what it produces. Saying you do not use it does not help; saying you use it for everything does not either.
- “How do you measure when there is less and less tracking data?” Talk about consent, first-party data (sign-ups, purchases, CRM), incrementality tests and accepting some uncertainty in attribution.
- “Which attribution model do you use?” There is no right answer. What they assess is whether you know the limits of the model you use and avoid making big decisions on the strength of a single report.
The case study
For senior roles you will often be set a case study: a launch plan, a diagnosis of their funnel or a budget split. You usually get a few days and then present it in a meeting.
The reasoning matters more than the slide design. Make clear which assumptions you made, what data you were missing, what you would do first and how you would know it had worked. Ten slides with sound judgement will do better than thirty with pretty charts.
In a marketing interview, the winner is not the person with the most brilliant idea, but the one who can reach a decision with little information and back it up with numbers. That shows in how you reason, not in what you propose.
How to prepare in a week
You do not need to revise a hundred questions. You need to know the job ad, know the company and have your stories in order. Here is a plan you can follow in five short sessions:
- Take the job ad apart
Separate the essentials from the nice-to-haves and underline the verbs: “manage”, “lead”, “optimise”. They tell you which stories you will need.
- Research their current marketing
Look at their website, their live ads in the Meta Ad Library and the Google Ads Transparency Center, their LinkedIn page and recent news. Note two things that work and one you would test.
- Build a bank of six stories
A success with numbers, a failure, a disagreement with another team, a low-budget project, a difficult decision about your team and something you learnt recently.
- Put a number on every story
Acquisition cost, conversion, revenue, time saved. If it is an estimate, write down how you got there so you can explain it.
- Rehearse out loud and prepare your questions
Tell each story in under two minutes with a timer running. Finish with three questions of your own about the role, the team and the goals for the first year.
The questions you ask
At the end you will almost always be asked whether you have any questions, and it is part of the assessment. Good ones: what the role needs to achieve in its first year and how that is measured, what budget and team there are, what happened to the previous person in the role and what is not working in their marketing today.
In a first interview, avoid asking only about holidays or working from home. They are fair questions, but they land better once there is interest on both sides. And if something in the conversation left you unsure, ask about it: you are assessing them too.
Frequently asked questions
How many STAR examples should I prepare?
Between five and eight, covering a success with numbers, a failure, a disagreement with another team, a low-budget project and a difficult decision about your team. Most questions can be answered by adapting one of them.
What if I do not have figures for my results?
Estimate honestly and explain where the figure comes from, such as an analytics tool or an internal report. If there really is no way to measure it, describe what changed in a way people could see: fewer complaints, more repeat orders, a shorter process.
Could I be asked to do a case study?
It is common for senior roles. You usually get a few days and then present it. The reasoning, the assumptions and the priorities matter more than how the slides look.
How do I research the company before the interview?
Their website, their live ads in the Meta Ad Library and the Google Ads Transparency Center, their LinkedIn page and recent news. That lets you talk about their marketing with facts rather than guesses.
What should I do if I am asked something I do not know?
Say so and think out loud: what you know, what you would need to find out and how you would find it. Making up an answer shows, and costs you far more than admitting a gap with a plan to close it.
