A growth strategy case interview tests how you would help a company expand its revenue, profit, customer base, or market share. You will see this case type in your first round and final round interviews at McKinsey, BCG, Bain, and most other top consulting firms.

 

This guide gives you the five-step approach to solve any growth case, the two case interview frameworks to know, six worked examples across industries, and the eight mistakes that cost candidates offers.

 

But first, a quick heads up:

 

McKinsey, BCG, Bain, and other top firms accept less than 1% of applicants every year. If you want to triple your chances of landing interviews and 8x your chances of passing them, watch my free 40-minute training.

 

What Changed in 2026?

 

This article was updated to add the Ansoff Matrix framework, six industry-specific case examples (SaaS, retail, healthcare, airlines, financial services, and industrial), a deeper prioritization rubric with a scoring table, and the eight most common mistakes interviewers cite.

 

The five-step solving method and the organic vs. inorganic framework were retained because both still match how MBB interviewers structure these cases in 2026.

 

What Is a Growth Strategy Case Interview?

 

A growth strategy case interview (also called a revenue growth case) gives you a company that wants to grow and asks you to figure out how. The growth target could be revenue, profit, market share, customer count, or unit volume.

 

The prompt usually looks something like this:

 

Your client, Coca-Cola, is looking for new opportunities to grow after years of flat growth. They have hired you to determine the best way to grow.

 

Growth strategy cases test five skills:

 

• Structured thinking: can you map every possible growth path?

 

• Strategic judgment: can you pick the best options under real-world constraints?

 

• Business acumen: do you understand what drives growth in different industries?

 

• Quantitative reasoning: can you size each opportunity and prioritize by impact?

 

• Recommendation discipline: can you commit to a clear answer with trade-offs?

 

Why Are Growth Strategy Cases So Common?

 

Growth strategy cases are one of the most common case types because almost every consulting project involves growth in some form. McKinsey research has shown that companies in the top quartile for revenue growth deliver roughly five times the shareholder returns of those in the bottom quartile, so growth is what clients pay consultants to figure out.

 

You will see growth cases at both rounds of every MBB interview process. They also appear constantly at Deloitte, EY-Parthenon, Strategy&, Kearney, and Oliver Wyman.

 

How Is a Growth Strategy Case Different From Other Case Types?

 

A growth strategy case is broader than other case types because it asks you to consider every possible path a company could take to grow. Profitability, market entry, M&A, and pricing cases each focus on a single lever, but a growth case forces you to evaluate all of them at once.

 

The table below shows how each case type compares.

 

Case Type	Core Question	Scope
Growth strategy	How can the company grow?	Broad (every possible path)
Profitability	Why are profits declining and how do we fix them?	Narrow (revenue minus costs)
Market entry	Should we enter market X, and how?	Narrow (one market)
M&A	Should we acquire company X?	Narrow (one target)
Pricing	How should we price product X?	Narrow (one lever)

 

Growth cases often turn into one of these narrower case types once the data points to a single lever. A growth case can become a pricing case interview if the issue is willingness to pay, or an M&A case if the answer is to acquire a competitor.

 

What Framework Should You Use for a Growth Strategy Case Interview?

 

The best framework for a growth strategy case interview splits growth into two paths: organic growth (internal expansion) and inorganic growth (external acquisitions and partnerships). This structure covers every possible way a company can grow and is easy for an interviewer to follow.

 

You can pair this framework with the Ansoff Matrix, which adds a product-market lens. Both are explained below.

 

What Is the Organic vs. Inorganic Growth Framework?

 

The organic vs. inorganic growth framework breaks every growth path into two buckets:

 

• Organic growth: growth driven by the company's own capabilities and efforts

 

• Inorganic growth: growth driven by acquisitions, joint ventures, or partnerships

 

Most companies pursue organic growth first because it is more sustainable. Inorganic growth is faster but more expensive and harder to execute.

 

How Does Organic Growth Work?

 

Organic growth splits into two parts: growth through existing revenue sources and growth through new revenue sources.

 

Growth through existing revenue sources comes from selling more units or selling at a higher average price per unit.

 

To increase quantity of units sold, a company can:

 

• Improve the product

 

• Reduce churn or increase repeat purchase rate

 

• Sell through new distribution channels (online, wholesale, marketplace)

 

• Target new customer segments

 

• Expand into new geographies

 

• Invest more in marketing and sales

 

To increase average price per unit sold, a company can:

 

• Raise prices on existing products

 

• Shift the product mix toward higher-priced items

 

• Add premium tiers or upsell features

 

• Bundle products together to raise basket size

 

Keep in mind that changing prices affects volume, so always check the net effect on revenue.

 

Growth through new revenue sources includes:

 

• Launching new products

 

• Launching new services

 

• Entering adjacent categories

 

• Adding subscription or recurring revenue layers on top of one-time products

 

How Does Inorganic Growth Work?

 

Inorganic growth splits into three paths: acquisitions, joint ventures, and partnerships.

 

Acquisitions

 

The first inorganic path is acquiring another company. The acquiring company immediately picks up the target's revenue, customers, products, and distribution channels.

 

Revenue synergies often follow. The combined company can cross-sell, up-sell, or bundle products that neither could offer alone.

 

The advantages are speed and full control. The main disadvantages are cost (acquirers typically pay a 20% to 40% premium over market value) and integration risk, which is why roughly 70% of acquisitions fail to create value according to Harvard Business Review research.

 

If the case is primarily about a specific acquisition target, it has become an M&A case interview and the framework should shift accordingly.

 

Joint Ventures

 

A joint venture is when two companies pool resources to pursue a specific opportunity. Each partner shares the profits, losses, and costs of the venture.

 

Joint ventures are cheaper than acquisitions and let companies share risk and expertise. The downside is shared control and a slower revenue ramp.

 

Partnerships

 

A partnership is a looser arrangement where two companies cooperate without combining resources. They might co-market, share customers, or refer business to each other.

 

Partnerships are the cheapest inorganic option and don't require a capital outlay. But revenue impact is usually smaller, and you don't control your partner's actions.

 

What Is the Ansoff Matrix and When Should You Use It?

 

The Ansoff Matrix is a four-quadrant framework that maps growth options across two dimensions: products (existing vs. new) and markets (existing vs. new). It was developed by mathematician Igor Ansoff in 1957 and is one of the most cited growth frameworks in MBA casebooks.

 

Quadrant	Products	Markets	Risk Level
Market Penetration	Existing	Existing	Lowest
Product Development	New	Existing	Medium
Market Expansion	Existing	New	Medium
Diversification	New	New	Highest

 

Market penetration means selling more of your existing products to your existing customers. Tactics include winning share from competitors, increasing usage frequency, raising basket size through upsells, and reducing churn.

 

Product development means launching new products to your existing customer base. Examples include line extensions (new flavors or sizes), new categories, service add-ons, and platform expansions.

 

Market expansion means taking your existing products to new markets. This can be a new geography, a new customer segment, or a new distribution channel.

 

Diversification means launching new products in new markets. This is the riskiest path and is rarely the recommended answer in case interviews because both sides of the business are unfamiliar.

 

So when should you use each framework? Use the Ansoff Matrix when the case is anchored around a product-market choice (a coffee chain deciding between new stores vs. new menu items). Use the organic vs. inorganic framework when the case is anchored around a build-vs-buy decision (a mature company deciding between internal expansion and acquisitions).

 

Strong candidates often combine both. Map the universe of options with one framework, then prioritize them with the other.

 

What Are the 5 Steps to Solving a Growth Strategy Case Interview?

 

Follow these five steps and you will be able to solve any growth strategy case that you get.

 

Step 1: Understand What the Company Is Trying to Grow

 

The first step is to identify what the company is trying to grow. Are they trying to grow revenues, profits, number of customers, market share, or something else?

 

Growing revenues versus growing profits can lead to very different strategies. Understanding what the company is trying to grow will help you determine which paths to consider first.

 

Interviewer: Your client, Coca-Cola, is looking for new opportunities to grow after years of flat growth. They have hired you to determine the best way to grow.

 

You: Is Coca-Cola looking to grow revenues, profits, or something else?

 

Interviewer: They are looking to grow revenues.

 

Step 2: Quantify the Specific Target or Goal

 

Next, quantify the goal the company is aiming for. How much of a revenue increase do they want, and in what time period?

 

This step is what most candidates skip. Without a quantified target, you cannot prioritize options or write a strong recommendation at the end.

 

You: How much is Coca-Cola looking to grow revenue by? And in what time period are they looking to achieve this level of growth?

 

Interviewer: They are looking to grow revenues by $1B over the next three years.

 

Step 3: Look at Potential Organic Growth Opportunities

 

Once you have quantified the goal, walk the interviewer through your framework. Start with organic growth because it is more sustainable and easier to control than inorganic growth.

 

You: To determine the best opportunities to achieve a $1B increase in revenues over the next three years, I would like to use the following framework. First, I'd like to consider potential organic growth opportunities, including growth through existing revenue sources and growth through new revenue sources. Next, I'd like to look into potential inorganic growth opportunities. Is there a particular acquisition, joint venture, or partnership that would make sense for Coca-Cola?

 

Interviewer: That sounds like a great plan. How should we proceed?

 

You: Let's look at organic growth opportunities first. Since Coca-Cola is a mature company that has seen flat growth, I am guessing that there won't be significant opportunities to increase revenues from existing revenue sources.

 

Interviewer: That seems like a reasonable assumption.

 

You: Okay, so let's look at potential new revenue sources. Are there particular drink beverage markets that Coca-Cola has no presence in that they could expand into?

 

Interviewer: Let me share with you these exhibits on potential drink beverage markets Coca-Cola could enter.

 

If you want to learn how to break down case math like this quickly, my case interview course walks you through every common case type in 7 days.

 

Step 4: Look at Potential Inorganic Growth Opportunities

 

After you have investigated the organic growth opportunities, move on to inorganic growth opportunities.

 

Consider whether an acquisition, joint venture, or partnership would be most appropriate given the company's situation. Each method of inorganic growth has different advantages and disadvantages.

 

You: After looking at organic growth opportunities, we determined that Coca-Cola could increase revenues by $600M by entering three niche drink beverage markets. However, we are still $400M in revenue short of our goal. I'd like to look into inorganic growth opportunities next.

 

Interviewer: That makes sense. There are a few acquisition targets Coca-Cola is considering. Let me share with you some further information.

 

Step 5: Prioritize and Recommend the Best Opportunities

 

Once you have investigated all the potential opportunities, prioritize and recommend the ones that are best for the company.

 

Score each growth opportunity on four criteria:

 

• Impact: how much revenue or profit does it add?

 

• Ease of implementation: how complex is it to execute?

 

• Cost: how much capital is required up front?

 

• Timing: how quickly will benefits materialize?

 

Make sure your recommendation hits the quantified target you established in step two.

 

You: To achieve its revenue growth target, I recommend that Coca-Cola enter three emerging drink beverage markets and acquire Company X. There are two reasons that support this.

 

One, Coca-Cola can use its existing production and distribution capabilities to gain meaningful market share in these emerging drink beverage markets quickly. They could increase revenues by $600M over three years fairly easily.

 

Two, the acquisition of Company X would add $500M in revenue, helping Coca-Cola exceed its $1B target. Additionally, there are several revenue synergies Coca-Cola can capture to grow revenues even more over the next few years.

 

For next steps, I'd like to look into Coca-Cola's market entry strategy for the emerging drink markets. I'd also like to assess whether the acquisition price for Company X is fair and reasonable.

 

Interviewer: Great. Thank you for your recommendation.

 

How Do You Prioritize Growth Opportunities?

 

Prioritize growth opportunities by scoring each one across four criteria: impact, ease of implementation, cost, and time to results. The table below shows how to apply this scoring rubric.

 

Criterion	What to Evaluate	High Score Looks Like
Impact	Revenue or profit potential	Adds 10%+ to top line
Ease of implementation	Operational complexity and capability gaps	Builds on existing capabilities
Cost	Upfront capital and ongoing investment	Less than 1 year payback
Time to results	How fast benefits show up	Material results within 12 months

 

A simple way to communicate this in an interview is a 2x2 matrix plotting options by impact (vertical axis) and feasibility (horizontal axis). High-impact, high-feasibility options go in the upper-right "do first" quadrant. Low-impact, low-feasibility options are "don't pursue."

 

When two options have similar impact, always pick the one that is easier and faster to execute. Speed compounds in real client work.

 

What Do Growth Strategy Cases Look Like Across Industries?

 

The framework stays the same across industries, but the most relevant growth levers change. Here is how to think about each.

 

SaaS and Tech: How Do You Grow a Software Company?

 

In SaaS, growth usually comes from three places: new customer acquisition, expansion revenue from existing customers, and reduced churn. A typical case might ask how a $50M ARR vertical SaaS company can reach $200M ARR in three years.

 

The strongest answers focus on net revenue retention. A SaaS company with 120% net revenue retention will roughly double every four years from existing accounts alone. Levers include adding seats, moving customers to higher tiers, attaching new modules, and reducing logo churn through customer success investments.

 

Retail and CPG: How Do You Grow a Consumer Brand?

 

Retail and consumer goods growth comes from same-store sales growth, new store openings, e-commerce expansion, and category extensions. A typical case might ask how a regional coffee chain can double revenue in five years.

 

The right answer almost always involves a portfolio approach: increase same-store sales through loyalty programs, expand the store footprint into adjacent regions, and add a retail or e-commerce channel (such as packaged coffee in grocery stores). Pure new-product launches are riskier and rarely the lead recommendation.

 

Healthcare: How Do You Grow a Provider or Payer?

 

Healthcare growth depends on whether the client is a provider (hospital, clinic, physician group), a payer (insurer), or a service company. For providers, growth comes from capacity expansion, payer mix improvement, service line additions, and partnerships with health systems.

 

Capacity is often the binding constraint. A hospital running at 90%+ occupancy cannot grow revenue without adding beds, opening new locations, or shifting case mix to higher-acuity (and higher-reimbursement) patients.

 

Airlines: How Do You Grow an Airline?

 

Airlines grow through network expansion (new routes, new hubs), capacity additions (more frequencies, larger aircraft), ancillary revenue (baggage, seat selection, food), and loyalty programs. Codeshare partnerships are a common inorganic lever.

 

Ancillary revenue has become one of the largest growth drivers in the industry. According to industry research, airlines collected over $130B globally in ancillary revenue in 2024, up from less than $30B a decade earlier.

 

Financial Services: How Do You Grow a Bank or Insurer?

 

Banks and insurers grow through wallet share (selling more products to existing customers), cross-sell into adjacent segments, fee income growth, and geographic expansion. Acquiring smaller competitors for their customer book is a common inorganic path.

 

A typical case might ask how a mid-sized regional bank can grow deposits by 15% in two years. The answer usually involves a mix of digital channel investments, branch optimization, and targeted segment campaigns rather than physical expansion.

 

Industrial: How Do You Grow a Manufacturer?

 

Industrial and manufacturing companies grow through aftermarket services (parts, maintenance, repairs), software and digital add-ons on top of hardware, geographic expansion, and roll-up acquisitions of smaller competitors.

 

Service revenue is often more profitable than equipment sales and grows faster. Many industrial cases come down to figuring out how to expand the service attach rate on the installed base.

 

What Are the Most Common Mistakes in Growth Strategy Case Interviews?

 

Most candidates lose growth cases by making the same predictable mistakes. Here are the eight that come up most often in coaching debriefs.

 

Mistake #1: Jumping to Solutions Before Clarifying What "Growth" Means

 

Candidates hear "the client wants to grow" and immediately start listing levers. Always ask: grow what (revenue, profit, customers, share), by how much, and in what time frame? Without these answers, your framework will be generic.

 

Mistake #2: Failing to Quantify the Target

 

A goal of "grow revenue" is not the same as a goal of "grow revenue by $500M in three years." The size of the gap determines which paths are realistic. Small gaps are usually closable through organic growth alone. Large gaps almost always require inorganic moves.

 

Mistake #3: Memorizing a Single Framework

 

Some candidates apply the same framework to every growth case. That works some of the time, but interviewers often design cases that don't fit a memorized template. Build your framework from the specific situation you are given, using organic vs. inorganic and the Ansoff Matrix as starting points rather than scripts.

 

Mistake #4: Listing Growth Ideas Without Prioritizing

 

A list of seven possible growth levers is not a recommendation. Interviewers want to see which two or three you would actually pursue and why. Use the impact-feasibility-cost-timing rubric to pick a small number and commit.

 

Mistake #5: Ignoring Trade-offs

 

Every growth move has trade-offs. Lowering prices grows volume but cuts margin. Acquisitions add revenue but tie up capital and create integration risk. Top candidates surface these trade-offs in their recommendation, average candidates pretend they don't exist.

 

Mistake #6: Forgetting to Size Each Opportunity

 

If the client wants to grow by $1B and you recommend three options, you need a rough estimate of how much revenue each option contributes. Without sizing, you cannot tell whether your portfolio actually hits the target.

 

Mistake #7: Treating All Growth as Good Growth

 

Not all growth creates value. Aggressive volume growth can dilute margins. New products can cannibalize existing revenue. Acquisitions priced too high destroy shareholder value. Strong candidates flag these risks rather than treating growth as automatically positive.

 

Mistake #8: Skipping the Recommendation

 

Some candidates spend so much time on analysis that they run out of time for a clean recommendation. The recommendation is what the interviewer scores you on most heavily. Always reserve the last few minutes to synthesize a clear answer with two or three reasons and a next step.

 

What Are the Best Tips for Acing a Growth Strategy Case Interview?

 

Tip #1: Always Quantify Before Structuring

 

Ask for the growth target and time frame before you write your framework. This single habit improves the quality of your structure more than any other.

 

Tip #2: Lead With Organic Growth

 

Walk through organic options first because they are more sustainable, cheaper, and easier for the client to control. Only move to inorganic options once organic growth alone won't close the gap.

 

Tip #3: Use the Ansoff Matrix as a Stress Test

 

Even if you structure with organic vs. inorganic, mentally check your options against the Ansoff Matrix to make sure you have not missed market penetration, product development, market expansion, or diversification opportunities.

 

Tip #4: Size Every Major Opportunity

 

Put a rough dollar estimate next to each growth lever you propose. Even a 30-second back-of-envelope estimate gives the interviewer confidence in your business judgment.

 

Tip #5: Recommend a Portfolio, Not a Single Move

 

Most strong recommendations include two or three growth moves that together close the gap. A single bet feels risky to the client, and a list of seven feels unfocused.

 

Tip #6: Build a Hypothesis Early

 

Once you have data on two or three options, form an early case interview hypothesis about which path will likely win, then test it as you analyze the remaining options. This makes your analysis faster and more focused.

 

Tip #7: Practice Across Industries

 

Growth cases feel different in SaaS, retail, healthcare, and industrials because the relevant levers change. Working through 5 to 10 growth cases across industries is the fastest way to build flexibility. If you want personalized feedback on your delivery, my case interview coaching program pairs you 1-on-1 with a former Bain interviewer.

 

Final Thoughts on Growth Strategy Cases

 

The most important part of solving growth strategy cases is to be structured and methodical when considering all the different growth opportunities. If you lay out a clear framework, the rest of the case should be a process of elimination.

 

Pay special attention to the context of the case and the company's circumstances. The stage of the company, how much free cash it has on hand, and the level of urgency it faces will help you narrow down options.

 

After practicing 5 to 10 growth cases, you will notice these cases follow a predictable pattern and you will be able to solve any growth strategy case that comes your way.

 

Frequently Asked Questions

 

What is a growth strategy case interview?

 

A growth strategy case interview is a consulting case where you are asked how a company can grow its revenue, profit, customer base, or market share. You typically structure the answer using two paths (organic growth through internal expansion, and inorganic growth through acquisitions or partnerships) and then prioritize specific opportunities by impact and feasibility.

 

What is the best framework for a growth strategy case?

 

The best framework splits growth into organic (internal) and inorganic (external) paths, then breaks each down into specific levers. You can also use the Ansoff Matrix to map options across products (existing vs. new) and markets (existing vs. new). Strong candidates often combine both lenses.

 

How do you start a growth strategy case interview?

 

Start by clarifying what the company wants to grow (revenue, profit, customers, share), how much they want to grow it, and over what time frame. Only after you have the quantified target should you walk the interviewer through your framework.

 

How is a growth strategy case different from a market entry case?

 

A growth strategy case is broader. A market entry case interview focuses on a single decision (should we enter market X and how) while a growth strategy case considers all possible growth paths, including new markets, new products, pricing, and acquisitions. Market entry is one quadrant of the Ansoff Matrix.

 

How is a growth strategy case different from a profitability case?

 

A growth strategy case asks how to expand the business. A profitability case interview asks why profits are declining and how to fix them. Growth is forward-looking and expansion-focused, profitability is diagnostic and fix-focused.

 

Should you recommend diversification in a growth case?

 

Rarely. Diversification (new products in new markets) is the riskiest quadrant of the Ansoff Matrix because the company is learning about new customers and building new capabilities at the same time. Only recommend diversification when other growth paths are exhausted and there are clear synergies with the core business.

 

How long does a growth strategy case interview usually last?

 

Growth strategy cases usually run between 25 and 40 minutes, similar to other case types. McKinsey cases tend to be shorter and more interviewer-led, while Bain and BCG cases tend to be longer and more candidate-led.
