100+ Case Interview Prompts for Business Students
If you're a business student gearing up for internship interviews, a case competition, or your first consulting-style interview, you've probably already heard the term "case interview" and felt a flicker of dread, not because the questions are impossible, but because there's no way to predict exactly what you'll get asked. The actual skill being tested isn't a memorized framework; it's whether you can structure an unfamiliar problem out loud, calmly, before you reach for an answer.
This guide is a bank of 112 real case prompts, organized by the kind of business problem each one is built around: profitability, market entry, market sizing, growth strategy, pricing, mergers and partnerships, operations, marketing, product launches, competitive response, nonprofit cases, and creative brainstorming. Skim to the categories most likely to show up in your own interview, then practice building a structure out loud, long before you ever look up a "correct" answer.
You can check out a list of business internships available for high-school students here! And if you’re looking for no-cost internships, find a list here.
This is a bank of 112 real case prompts, organized into twelve categories: profitability, market entry, market sizing, growth strategy, pricing, mergers and partnerships, operations, marketing, product launches, competitive response, nonprofit cases, and creative brainstorming. The actual skill being tested isn't a memorized framework; it's whether you can structure an unfamiliar problem out loud, calmly, before reaching for an answer. Before answering out loud, always restate the problem in your own words and lay out a structure before touching a single number. It's useful for any student prepping for a business internship interview, case competition, or consulting-style interview process.
Why do case interviews now show up outside of consulting recruiting?
Case interviews used to be a consulting-specific hurdle, but the format has spread well past that. Business, product, and even some nonprofit internship interviews now include a short case prompt to see how a candidate thinks under pressure, not just what they already happen to know. It rewards people who can break down an unfamiliar problem calmly and out loud, not people who already know the "right" answer going in.
That same structured, on-your-feet thinking is exactly what a real internship asks for once you're actually on a project. In a program like Ladder Internships, students get placed on a real business problem for an actual startup or nonprofit, working alongside a company manager and a dedicated Ladder Coach, and the instinct a case prompt is testing, breaking a vague problem into a structure before reaching for an answer, is the same one that carries a student through the first genuinely ambiguous week of a real project. More on that below.
How do you find the right prompts to practice with?
Each section below covers one type of case problem, numbered continuously from 1 through 112 so the count itself proves the list is real, not padded to hit a round number. Every prompt is written the way an interviewer would actually phrase it, a specific scenario ending in a question, rather than an abstract description of the category.
You don't need to work through every prompt in a section, and you almost never want to memorize an answer to any single one. Pick the categories closest to the kind of interview you're actually prepping for, and practice the structure, not the specific conclusion.
Profitability and declining performance cases
These cases test whether you can find the real cause behind a number moving the wrong direction, not just recite a framework for spotting it.
Retail profit decline: A mid-sized clothing retailer's profits have dropped 20% over the past two years. What's causing it, and what would you recommend?

New country expansion: A US-based skincare brand is deciding whether to enter the Canadian market. What should it evaluate first?
Grocery delivery entry: Should a regional grocery delivery startup expand into a neighboring state?

University partnership entry: An ed-tech company wants to partner with universities to enter the higher-ed market. Where should it start?
Market sizing and guesstimate cases
These are less about landing on the exact number and more about whether your logic holds up out loud, since no interviewer expects you to actually know the real figure.

B2B upsell growth: A B2B software company wants to grow revenue from existing accounts rather than new sales. What levers exist?
Pricing strategy cases
Pricing cases are some of the easiest to get wrong by guessing, since the right answer almost always depends on a tradeoff you have to name explicitly.
Price increase decision: A software company is considering a 15% price increase. How would you decide if it's a good idea?
Freemium to paid conversion: A freemium app has strong signups but weak conversion to paid. What pricing changes would you test?
Discount strategy: Should a retailer run frequent discounts, or hold a firm price and compete on quality?

Loyalty discount tradeoff: A retailer is deciding whether its loyalty discount program is actually profitable. How would you evaluate it?
Mergers, acquisitions, and partnership cases

These cases reward finding the actual bottleneck, not just proposing a generic list of cost cuts.
Supply chain disruption: A retailer's main supplier has suddenly become unreliable. What should it do?
Warehouse inefficiency: A company's warehouse costs have grown faster than its order volume. Why, and what's the fix?

Rebrand decision: A legacy brand is losing relevance with younger customers. Should it rebrand?
Brand awareness gap: A strong product has low brand awareness compared to weaker competitors. What would you recommend?
Influencer strategy: Should a skincare brand shift its marketing budget from traditional ads to influencer partnerships?

Declining ad ROI: A company's advertising spend has increased but returns have dropped. Why might that be?
New market segment messaging: How should a company adjust its messaging to reach a completely new customer segment?
Sponsorship decision: Should a beverage brand sponsor a college sports team to build awareness among students?

Service area expansion tradeoff: A nonprofit is deciding between deepening service in its current area or expanding to a new one. Which is the better call?
Creativity and brainstorming cases
These cases test the range of ideas you can generate more than a single polished answer, since the interviewer is watching how you think, not just which option you land on.
New use for an existing product: Brainstorm three new uses for a product that's currently sold for just one purpose.
Turning a failing product around: A once-popular product's sales have quietly declined for years. Brainstorm ways to bring it back.

Building word of mouth from scratch: A brand-new company has zero brand awareness and no marketing budget. Brainstorm three ways it could still generate buzz.
How should you actually practice with these prompts?
Reading through 112 prompts is not the same as practicing 112 cases, and the actual skill lives in one specific habit: before you say anything about the business problem itself, restate it in your own words and lay out how you plan to break it down, out loud, even when you're practicing alone. Interviewers are listening to the structure as much as the eventual answer, and a case that opens with a clear framework and a genuine first hypothesis reads completely differently than one that opens with a scattered first reaction.
If you're using these prompts to prepare for an interview with a program like Ladder Internships, the same instinct is worth building early. Ladder's own interview process looks for self-motivated, clear communicators over the most decorated resume, and a candidate who can calmly structure an unfamiliar problem out loud is demonstrating exactly that, not reciting a script. The habit doesn't disappear once you're accepted, either: a real project inside a startup or nonprofit rarely arrives pre-structured, and breaking a vague problem into pieces is the same muscle a case interview is built to test.
Common questions about case interview prep for students
1. Do I need consulting or business experience before I can practice these?
No. Most of these prompts test how you think through an unfamiliar problem, not whether you already know finance or strategy frameworks. Anyone comfortable structuring an argument out loud can start practicing today.
2. How long should I spend on a single prompt?
Around 15 to 20 minutes is realistic for a first pass: a couple of minutes to structure the problem, the rest working through it out loud. Rushing past the structuring step is the most common shortcut that actually hurts a real interview.
3. What if I get stuck partway through a case?
Say so out loud instead of freezing. Naming exactly where you're stuck, and what you'd need to know to move forward, reads as clear thinking under pressure, which is closer to what the prompt is testing than a lucky guess would be.
4. Are these prompts only useful if I'm interviewing for a consulting internship?
No. Business, product, and even some nonprofit internship interviews increasingly borrow the same format, and the underlying skill, breaking a vague problem into a structure before reaching for an answer, shows up in plenty of internships that never use the word "case" at all.
