Marketing Case Study Presentation: How to Prepare for the Final Round

What is a marketing case study interview?

It’s a final-round task where you’re given a business problem and asked to present how you’d solve it. Sometimes it’s a take-home brief with a few days to prepare; sometimes it’s a problem handed to you in the room with 30 minutes to think.

That can sound intimidating, but it’s good news: the panel isn’t looking for the right answer. They’re watching how you think: whether you start from the business problem, find a real insight, make a clear choice and know how you’d tell if it worked.

Common case study briefs for marketing roles

Most briefs fall into a few types. Knowing which one you’ve got helps you shape the answer.

• "How would you grow brand X?" Usually about the company itself. Research matters most here.
• "Plan the launch of product Y." Audience, positioning, channels, budget split, measures.
• "Here’s our data, what would you do?" An analysis task. Show the one or two findings that matter, not every chart.
• "Present a campaign you’re proud of." About your past work. Lead with the problem and the result, not the creative.
• "Your first 90 days." Close to a 30-60-90 day plan.

A slide-by-slide outline

Seven or eight slides is enough for a 20-minute slot. Write each slide’s headline as the point you’re making, so a panel member skimming the deck later still gets the argument.

1. THE ASK — [Restate the brief in one line, and what a good answer would let them decide]

2. THE SITUATION — [Three facts about the brand and its market, each with a source]

3. THE INSIGHT — [The one thing you noticed that changes the answer, e.g. "Demand is falling across the whole category, not just for us"]

4. THE RECOMMENDATION — [What you'd do, in one sentence, and why this rather than the obvious alternative]

5. HOW IT WORKS — [Audience, message, channels, rough budget split]

6. HOW WE'D KNOW — [Two or three measures, today's baseline and a target]

7. FIRST 90 DAYS — [What you'd do first, what you'd test, when you'd decide]

8. WHAT I'D WANT TO CHECK — [The assumptions you made, and the data you'd want before committing]

The last slide matters more than people think. Saying what you’d check before acting shows judgment, and it answers the panel’s hardest questions before they ask them.

The outline gives you a structure, not a voice. Present it the way you’d talk a colleague through an idea you believe in, with your own phrasing and opinions; the panel is picturing you on the team, and that’s easier when they hear the real you.

How much work should you put in?

Enough to make one strong argument, not a full strategy. If the brief says “no more than five slides”, keep to five. Going over the limit is the most common way candidates lose points before they’ve said a word.

For a take-home brief, a reasonable effort is four to eight hours. If the company asks for much more than that, it’s fair to ask how they’ll use the work.

Where to get the facts

Your situation slide is only as good as its sources. For a brand question, use what you can see from outside: search demand compared with rivals (share of search), social engagement, the ads they run, what customers say in comments and reviews, and, for public companies, revenue and ad spend from their filings.

Put a small source line on every slide with a number. When someone asks “where’s that from?”, you’ll have the answer. Our guide to running a brand audit has a checklist of what to look at.

How to handle the panel’s questions

Expect the questions to take as long as the presentation. Prepare for them the same way.

• For each slide, write the hardest question it invites, and a short answer.
• When you don’t know, say so and say how you’d find out. “I couldn’t see your retention data, so I assumed X. If it’s Y, I’d change the recommendation to Z.”
• Don’t defend every point. If someone gives you information you didn’t have, adjust in the room. That’s what they want to see.
• Bring it back to the decision. End answers by restating what you’d do.

Mistakes that sink case presentations

• No point of view. Six options with pros and cons isn’t a recommendation. Pick one and say why.
• Too many slides. If you’re rushing at the end, you prepared too much. Cut to the slides that carry the argument.
• Generic tactics. “Use influencers and TikTok” without saying which, why and how you’d judge it. Name the specifics, even as a hypothesis.
• Made-up numbers. If you estimate, say it’s an estimate and how you got it.
• Reading the slides. Talk to the people, not the screen. Rehearse it out loud twice and you won’t need to read.

FAQ

How long should a marketing case study presentation be?

Usually 15 to 20 minutes of presenting, with the same again for questions. Check the brief; if it gives a time, finish a couple of minutes under it.

Should I send the slides in advance?

Only if they ask. Otherwise bring them on a laptop and a USB stick, and send a PDF in your thank-you email afterwards.

What if I disagree with the brief?

Say so briefly and answer it anyway. “The brief asks about awareness; I think the bigger problem is retention, and here’s why. But here’s how I’d tackle awareness.” Skipping the brief looks like you didn’t listen.

Can I use AI tools to help prepare?

It’s your call and the company’s. Many interviewers assume you’ll use them for research and drafting. What they’re judging is your thinking, so make sure every claim is one you can explain and every number has a source you’ve checked.
