How to Present a Marketing Case Study in an Interview
A marketing case study presentation is a short presentation you may be asked to give during a job interview. The employer gives you a business problem, and you explain how you would approach it. Your job is to make your idea easy to understand and explain why you chose it.
What does a marketing case presentation involve?
Imagine you’re interviewing for a marketing role at a café. The interviewer says: “Our afternoons are quiet. How would you bring in more customers?” They ask you to prepare a short presentation with your ideas.
You might suggest an afternoon coffee-and-snack offer, explain who it is for, and describe how you would try it. That is a marketing case presentation. You are showing how you think through a practical problem.
This guide uses that fictional café example. The slide headings below show how you could organize your own presentation. Adapt them to the employer’s assignment rather than copying the example as your submission.
Read the assignment before making slides
Start with the instructions. A good idea can still miss the mark if it answers a different question from the one the employer asked.
Check these details before you begin:
What problem are you being asked to solve?
Who is the customer or audience?
How much time do you have to present?
Is there a budget, slide limit, or required format?
Are you expected to use company data or do your own research?
If something important is missing, ask. For the café, a useful question would be: “Are we trying to attract new customers, or encourage existing customers to visit in the afternoon?”
If you can’t ask, state your assumption: “For this example, I’m focusing on people who already live or work nearby.” That gives the interviewer a clear starting point.
Use a simple four-part presentation
If the employer hasn’t given you a structure, four main slides can be a useful starting point for a short presentation. Add supporting detail only when it helps answer the brief.
Slide 1: What is the problem?
Keep the first slide focused on the goal. Avoid opening with a long company history.
Example slide title: Bring more nearby customers into the café in the afternoon
You could explain it like this: “The goal is to bring in more customers during the quiet afternoon period. I’m focusing on people nearby who could stop in for a short break.”
Slide 2: What do you recommend?
Give the interviewer one clear idea. Explain who it is for and what you would do.
Example slide title: Test a weekday coffee-and-snack offer from 2 to 4 p.m.
You could say: “I would try a simple afternoon offer aimed at nearby workers and residents. I’d promote it through the café’s existing channels and make the offer easy to spot in the window.”
The offer is a proposal, not a proven solution. You would still need to check the café’s costs, staffing, and ability to serve those customers.
Slide 3: Why did you choose that idea?
Explain the connection between the problem and your recommendation. Use the information you’ve been given. Be clear when something is an assumption.
Example slide title: Give nearby customers a reason to visit during the quiet period
You could say: “The offer is available during the hours we want to improve. Using existing channels would let us start small. I’m assuming nearby customers would be interested in an afternoon break, so I would check that with staff observations and a few customer conversations.”
You can briefly mention another option: “I considered a larger paid advertising campaign, but I’d first check whether this smaller offer attracts customers at a cost the café can afford.”
Slide 4: How would you know if it worked?
Show how you would try the idea and decide what to do next. Avoid promising a result you can’t support.
Example slide title: Track afternoon visits, sales, and the cost of the offer
You could say: “I’d run a small trial and compare afternoon activity with similar weekdays before the offer. I’d track visits, sales, and whether the offer leaves enough profit. I’d also consider other changes, such as weather or local events, before giving the offer all the credit.”
Finish with the next decision: “If it brings in extra customers at a worthwhile margin, I would consider continuing. If it mostly discounts purchases people would have made anyway, I would change or stop it.”
Make your slides easy to read
The four sections above are an outline for your own slides. You don’t need to paste every sample sentence onto them. Put the main point on the slide and explain the rest out loud.
Use one clear headline per slide
Keep the text short and large enough to read
Include a chart or image only when it helps explain your idea
Use consistent fonts, colors, and spacing
Put extra research or calculations in backup slides
For example, your recommendation slide might contain the offer, the audience, and the trial period. The longer explanation belongs in your presentation notes.
Explain your idea like you’re having a conversation
A simple opening helps the interviewer follow you:
“I’d start with a small afternoon offer for nearby customers. I’ll explain who it is for, why I chose it, and how I would decide whether to continue.”
Practice saying that in your own words. You should know your main points well enough to explain them without reading the slides word for word.
You can use the same approach from our guide to answering tough interview questions without sounding rehearsed: prepare the ideas, then let the wording change naturally.
Prepare for follow-up questions
Ask yourself where the interviewer might challenge your plan. For the café example, that could include:
Why would customers want this offer?
What if the café loses money on it?
What information would you need before launching?
What would make you change your recommendation?
If you don’t know an answer, explain what you would check. For example: “I’d need the ingredient costs and average order value before choosing a price. I wouldn’t recommend a discount without checking the margin.”
That is a clearer answer than inventing a number. You can be confident about your approach while being honest about what you still need to learn.
Do one practice run before the interview
Present out loud with a timer. Check that you answer the assignment, explain your recommendation, and leave enough time for questions.
Ask someone to listen and tell you what they think your main idea is. If they can’t explain it back in one sentence, simplify your opening or remove details that distract from it.
Save a PDF backup and check that the text is readable. For the rest of your preparation, follow our practical interview preparation steps.

Frequently asked questions
What is a marketing case study presentation interview?
It is an interview assignment where you present your approach to a marketing problem. The employer may give you a scenario, company information, or data and ask you to recommend what to do. Follow the specific instructions in the brief.
How many slides should I use?
Follow the employer’s slide limit and time limit. If no structure is provided, four main slides covering the problem, recommendation, reasoning, and measurement can be a useful starting point. Use extra slides only when the assignment needs them.
Do I need complicated calculations?
Only if they help answer the assignment. A data-focused case may require calculations, while a campaign idea may need more explanation of the audience and message. Explain any numbers you use and label assumptions clearly.
What if I don’t have enough information?
Ask for clarification where possible. Otherwise, state the assumptions behind your answer and explain what you would check before putting the idea into practice. Don’t present invented details as company facts.
Should I memorize my presentation?
Know your main points and practice out loud, but avoid memorizing every sentence. You need to be able to answer questions, explain your reasoning, and adjust when the interviewer gives you new information.
