TMT Case Interview: Step-by-Step Guide (2026)

Author: Taylor Warfield, Former Bain Manager and interviewer

Last Updated: April 6, 2026

 

TMT case interviews are consulting case interviews focused on technology, media, and telecommunications business problems. They follow the same core structure as standard case interviews but require familiarity with TMT-specific metrics like ARPU, churn rate, and customer acquisition cost. Whether you are interviewing at a TMT-focused firm like Altman Solon or tackling an industry case at McKinsey, BCG, or Bain, this guide walks you through everything you need to know.

 

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 Is a TMT Case Interview?

 

A TMT case interview is a 30 to 45-minute exercise where you solve a business problem involving a technology, media, or telecommunications company. The interviewer presents a scenario, and you work together to structure the problem, analyze data, and develop a recommendation. TMT cases are used by both specialized TMT consulting firms and general strategy firms when assigning industry-specific cases.

 

According to Vault's consulting rankings, McKinsey, BCG, and Bain are consistently rated as the top three firms for TMT consulting, with Accenture, Deloitte, and specialized boutiques close behind. TMT is one of the largest and fastest-growing practice areas in consulting. The global TMT consulting market exceeded $10 billion in 2025, driven by demand for AI, 5G, and cloud strategy work.

 

What Does TMT Stand For?

 

TMT stands for Technology, Media, and Telecommunications. These three sectors are grouped together because they are deeply interconnected. Technology companies build the platforms and software that media companies use to distribute content, while telecom companies provide the networks that carry both.

 

In a consulting context, TMT covers a wide range of clients. Technology includes SaaS platforms, cloud providers, semiconductor companies, and consumer electronics. Media includes streaming services, digital advertising, publishing, and gaming. Telecommunications includes wireless carriers, broadband providers, cable operators, and infrastructure companies.

 

How Do TMT Cases Differ from Standard Case Interviews?

 

TMT case interviews follow the same fundamental structure as standard consulting cases. You still need to clarify the objective, build a framework, analyze data, and deliver a recommendation. The difference is in the content, not the format. Here is how they compare:

 

Dimension

Standard Case Interview

TMT Case Interview

Industry focus

Any industry (retail, healthcare, etc.)

Technology, media, or telecom

Key metrics

Revenue, cost, margin, market share

ARPU, churn rate, CAC, CLV, DAU/MAU

Revenue models

Product sales, services

Subscriptions, advertising, freemium, licensing

Common case types

Profitability, market entry, M&A

Same types, but with TMT-specific context

Technical knowledge

Minimal

Helpful to know TMT terminology and business models

Framework approach

Standard frameworks apply

Standard frameworks plus TMT-specific factors like network effects and switching costs

 

The takeaway is that you do not need to be a telecom engineer or software developer to pass a TMT case. You do need to understand how TMT companies make money, what their biggest cost drivers are, and which metrics matter most. The analytical approach is the same. For a full breakdown of standard case solving techniques, read our case interview guide.

 

Which Consulting Firms Give TMT Case Interviews?

 

You can encounter a TMT case at almost any consulting firm, but some firms are much more likely to give them than others. TMT-specialized firms will give TMT cases in nearly every interview. Generalist strategy firms give TMT cases when the interviewer works in a TMT practice or when your resume signals technology or media experience.

Altman Solon is the largest consulting firm exclusively focused on TMT. They have over 600 consultants globally and their cases almost always involve a tech, media, or telecom client. According to their interview guide, Altman Solon uses both interviewer-led and candidate-led formats, with each case lasting 30 to 45 minutes.

 

What TMT Industry Knowledge Do You Need?

 

You do not need deep technical expertise to pass a TMT case interview. What you do need is a working understanding of how TMT companies make money, what drives their costs, and which business models dominate each sector. In my experience at Bain, candidates who understood the basics of recurring revenue models and could talk about churn and ARPU without hesitation performed significantly better on TMT cases.

 

Key Technology Concepts

 

Technology cases revolve around a few recurring themes. SaaS (Software as a Service) companies sell software on a subscription basis, and their key challenge is balancing customer acquisition cost against lifetime value. Cloud computing cases often involve pricing strategies, capacity planning, or migration decisions. Consumer tech cases frequently test market entry or competitive positioning.

 

Important concepts to know:

 

  • Network effects: A product becomes more valuable as more people use it. Social media platforms and marketplaces are classic examples. A case might ask you to evaluate how strong a company's network effects are and whether a new entrant can overcome them.

 

  • Switching costs: The cost or effort a customer faces when moving to a competitor. Enterprise software companies have high switching costs because migrating data and retraining employees is expensive.

 

  • Freemium model: A pricing strategy where the basic product is free but premium features cost money. Roughly 2% to 5% of freemium users typically convert to paid plans, according to industry benchmarks.

 

  • Platform economics: Two-sided platforms (like app stores or ride-sharing) connect buyers and sellers. Cases often involve optimizing the balance between supply and demand on both sides.

 

Key Media Concepts

 

Media cases tend to focus on content strategy, advertising revenue, and the shift from traditional to digital distribution. The streaming wars have made this sector a frequent case topic. According to industry data, global streaming revenue surpassed $100 billion in 2024 and continues to grow at roughly 10% annually.

 

Important concepts to know:

 

  • Ad-supported vs. subscription models: Some media companies monetize through advertising (like free streaming tiers), while others charge a monthly subscription. Many now offer both. A case might ask you to evaluate which model is more profitable.

 

  • Content economics: Original content production is expensive. A single season of a high-end streaming show can cost $100 million or more. Cases may ask you to evaluate whether investing in original content generates positive ROI.

 

  • CPM (Cost Per Mille): The price an advertiser pays per 1,000 ad impressions. Digital CPMs vary widely, from $2 to $3 for display ads to $20 or more for premium video placements.

 

  • DAU/MAU ratio: Daily active users divided by monthly active users. This measures engagement stickiness. A DAU/MAU ratio above 50% is considered very strong. Social media platforms and gaming companies track this closely.

 

Key Telecom Concepts

 

Telecom cases are common at both specialized and generalist firms. Telecom companies operate subscription-based business models with high fixed costs (building and maintaining networks) and low variable costs per additional customer. This cost structure means maximizing subscribers and ARPU is critical. For a deeper dive into telecom-specific preparation, check out our telecom case interview guide.

 

Important concepts to know:

 

  • 5G and infrastructure investment: Major carriers have invested hundreds of billions of dollars in 5G rollout. Cases may involve evaluating the return on infrastructure investments or deciding where to deploy network upgrades first.

 

  • Bundling strategies: Many telecom companies bundle internet, TV, and mobile services (called triple play or quad play) to increase ARPU and reduce churn.

 

  • Spectrum auctions: Wireless carriers bid for radio frequency spectrum from governments. Spectrum is a finite resource, and the cost of acquiring it can reach tens of billions of dollars.

 

  • Fixed vs. mobile: Telecom companies often operate both fixed-line (broadband, fiber) and mobile (wireless) networks. Cases may involve evaluating which segment to prioritize for investment.

 

TMT Metrics Cheat Sheet

 

The following metrics come up frequently in TMT case interviews. Knowing their definitions and why they matter will save you valuable time during the case and signal to the interviewer that you understand the industry.

 

Metric

Definition

Why It Matters in Cases

ARPU

Average Revenue Per User. Total revenue divided by total subscribers.

The single most important metric for subscription businesses. Drives revenue analysis.

Churn Rate

Percentage of customers who cancel per month or year.

A 2% monthly churn means losing roughly 22% of customers annually. Reducing churn is usually cheaper than acquiring new customers.

CAC

Customer Acquisition Cost. Total sales and marketing spend divided by new customers acquired.

If CAC exceeds CLV, the business is unprofitable on a per-customer basis.

CLV

Customer Lifetime Value. Expected total profit from a customer over their entire relationship.

The CLV to CAC ratio is a key indicator of business health. A ratio of 3:1 or higher is typically considered strong.

DAU/MAU

Daily Active Users divided by Monthly Active Users. Measures engagement.

High ratios (above 50%) indicate strong user stickiness. Low ratios suggest engagement problems.

CPM

Cost Per Mille. Price per 1,000 ad impressions.

Drives revenue calculations for ad-supported media businesses.

MRR/ARR

Monthly or Annual Recurring Revenue.

The foundation of SaaS valuation. Growth rate of ARR is a critical indicator for tech companies.

Take Rate

Percentage of transaction value a platform keeps as revenue.

Key metric for marketplace businesses. App stores typically take 15% to 30%.

 

How Do You Solve a TMT Case Interview Step by Step?

 

The process for solving a TMT case interview is the same six-step process used for any consulting case. The difference is that you will apply TMT-specific knowledge at each step. If you have practiced standard cases, you already have 80% of what you need. The remaining 20% comes from understanding TMT industry dynamics. For more on the standard approach, see our guide to case interview frameworks.

 

Step 1: Understand the Business Problem

 

Listen carefully as the interviewer reads the case prompt. Take notes on the company, industry, and objective. TMT cases often include specific metrics in the prompt (like subscriber counts, ARPU, or churn rates). Write these numbers down because you will almost certainly need them later.

 

After the interviewer finishes, restate the objective in your own words. For example: "So our client is a wireless carrier with 50 million subscribers that has seen ARPU decline by 15% over the past two years. Our goal is to identify what is causing the decline and recommend actions to reverse it. Is that correct?"

 

Step 2: Ask TMT-Specific Clarifying Questions

 

Good clarifying questions show the interviewer that you understand TMT. Instead of only asking generic questions like "What is the time frame?", add questions that are specific to the industry. Here are examples:

 

  • For a telecom case: "Is the client primarily a mobile carrier, a broadband provider, or both?"

 

  • For a media case: "Is the client's revenue primarily ad-supported, subscription-based, or a mix?"

 

  • For a technology case: "Is the client a SaaS business with recurring revenue or a product company with one-time sales?"

 

  • For any TMT case: "Are we looking at a specific geography or the global business?"

 

Asking smart clarifying questions takes 60 seconds but can change your entire approach. Getting clarity on the revenue model upfront prevents you from building the wrong framework.

 

Step 3: Build a TMT Case Framework

 

After clarifying questions, take 60 to 90 seconds to structure your framework. The framework should have 3 to 4 major buckets tailored to the specific case. Do not memorize a single "TMT framework" and force it onto every case. Instead, pick the 3 to 4 areas that are most critical to answering the case objective.

 

For example, if the case asks why a streaming platform is losing subscribers, your framework might include: subscriber trends (who is leaving and why), content and product quality (is the offering competitive), pricing and value perception (are customers getting enough for the price), and competitive dynamics (what are rivals doing differently).

 

If you want to learn how to build custom frameworks for any case type, our case interview frameworks guide covers four different strategies.

 

Step 4: Solve Quantitative Problems

 

TMT cases frequently involve calculations with industry-specific metrics. Before crunching numbers, lay out your approach. Common quantitative problems in TMT cases include:

 

  • Revenue calculation: Revenue = Subscribers x ARPU. If a carrier has 50 million subscribers at $45 ARPU, monthly revenue is $2.25 billion.

 

  • Churn impact: If monthly churn is 2%, the carrier loses 1 million subscribers per month. Over a year, that is roughly 12 million lost subscribers (before accounting for new sign-ups).

 

  • CLV calculation: If a customer pays $50 per month, stays an average of 24 months, and the margin is 40%, CLV = $50 x 24 x 0.40 = $480.

 

  • Market sizing: Estimate the addressable market for a new streaming service by starting with the population, filtering by internet access, then estimating willingness to pay.

 

Always connect your math back to the case objective. After calculating that churn costs the client $540 million in annual revenue, explain what that means for the recommendation.

 

Step 5: Answer Qualitative Questions

 

TMT cases will also include qualitative questions. You might be asked to brainstorm ways to reduce churn, evaluate whether a telecom company should launch a streaming service, or assess the risks of a media acquisition.

 

Structure your qualitative answers the same way you would in any case. Use a simple organizing framework like internal vs. external factors, short-term vs. long-term options, or customer vs. competitor vs. company perspectives. This shows the interviewer that you think in a structured way even when the question is open-ended.

 

Step 6: Deliver Your Recommendation

 

End the case with a clear, firm recommendation. State it in one sentence, then support it with two to three reasons backed by evidence from the case. Finish with one or two next steps you would explore with more time.

 

For example: "I recommend that our client invest $200 million in fiber-to-the-home deployment in the top 10 metro areas. First, these markets represent 60% of the addressable opportunity with only 30% fiber penetration today. Second, our analysis shows that fiber customers have 40% higher ARPU and 50% lower churn than DSL customers. Third, the payback period is under 4 years at current subscriber acquisition rates. As a next step, I would analyze the competitive response from cable providers in these markets."

 

What Frameworks Work Best for TMT Cases?

 

There is no single "TMT framework" you should memorize. The best approach is to use the same framework-building strategies you would use for any case, but layer in TMT-specific factors. Here are three common case types and how to tailor your framework for a TMT context.

 

TMT Profitability Framework

 

A profitability case in TMT still uses the standard Profit = Revenue minus Costs structure. The TMT-specific twist is in how you break down revenue and costs:

 

  • Revenue side: Break revenue into subscribers x ARPU. Then ask whether subscriber count is declining, ARPU is declining, or both. Segment by product (mobile, broadband, enterprise) and by customer type (prepaid vs. postpaid, consumer vs. business).

 

  • Cost side: TMT companies have high fixed costs (network infrastructure, content licensing, R&D) and relatively low variable costs. Look at whether fixed costs have increased (new infrastructure investments) or whether the company is losing scale efficiency as subscribers decline.

TMT Market Entry Framework

 

For a market entry case in TMT, you still need to evaluate market attractiveness, competition, company capabilities, and profitability. Add these TMT-specific considerations:

 

  • Network effects and switching costs: Does the market have strong network effects that protect incumbents? Are switching costs high enough to make customer acquisition difficult?

 

  • Regulatory environment: TMT industries are heavily regulated. Telecom spectrum is licensed by governments. Media companies face content regulations. Data privacy laws like GDPR affect technology companies. Factor these into your entry analysis.

 

  • Technology and infrastructure requirements: Does the client need to build or lease physical infrastructure (towers, fiber, data centers)? What is the capital expenditure required and how long until breakeven?

 

TMT Pricing and Monetization Framework

 

TMT pricing cases are especially common because the sector uses diverse monetization models. A useful framework considers three pricing approaches:

 

  • Cost-based pricing: What are the costs to serve each customer? In telecom, the marginal cost of an additional subscriber on an existing network is very low, giving significant pricing flexibility.

 

  • Competitor-based pricing: What are rivals charging? Telecom and streaming markets are fiercely competitive, and pricing above the market average risks churn unless the product is clearly differentiated.

 

  • Value-based pricing: What value does the customer receive? Enterprise SaaS companies often price based on the ROI their product delivers to clients, which allows for premium pricing if the value proposition is strong.

 

TMT Case Interview Example with Sample Answers

 

Here is a TMT case walkthrough to show you how these concepts come together in practice.

 

Case prompt: Your client is a major streaming platform with 80 million subscribers globally. Over the past 12 months, subscriber growth has stalled and profitability has declined by $300 million. The CEO wants to understand what is happening and what the company should do about it.

 

Clarifying questions you might ask:

 

  • Is the decline driven by subscriber losses, ARPU decline, cost increases, or a combination?

 

  • Which geographies are most affected?

 

  • Has the company recently changed pricing or content strategy?

 

Information revealed: Subscriber count has been flat (churn has increased from 4% to 6% monthly, but new sign-ups have offset it). ARPU has dropped from $12 to $10.50 due to a shift toward a lower-priced ad-supported tier. Content costs have increased 25% year over year.

 

Framework: You propose analyzing four areas: (1) subscriber trends and churn drivers, (2) ARPU and revenue mix, (3) content cost efficiency, and (4) competitive positioning.

 

Quantitative analysis: Monthly revenue before = 80M x $12 = $960M. Monthly revenue now = 80M x $10.50 = $840M. That is a $120M monthly revenue drop, or $1.44B annually. Content costs rose 25%, adding roughly $500M if the annual content budget was $2B. Together, these factors explain the $300M profit decline and then some.

 

Recommendation: "I recommend three actions. First, optimize the ad-supported tier by increasing ad load modestly and introducing higher-CPM ad formats. Based on our analysis, a $2 CPM increase across the ad tier could add $200M in annual revenue. Second, invest content spending more selectively by focusing on genres with the highest engagement-per-dollar. Third, reduce churn on the premium tier by introducing annual billing discounts and exclusive content. Reducing monthly churn from 6% to 5% would retain approximately 800,000 additional subscribers per month."

  • 10. Technology: A private equity firm is evaluating the acquisition of a cybersecurity startup with $100 million in ARR growing at 30%. Should they acquire it?

 

What Are the Most Common Mistakes in TMT Cases?

 

Having coached hundreds of candidates, I see the same mistakes come up repeatedly in TMT case interviews. Avoiding these will put you ahead of most candidates.

 

  • Ignoring the revenue model: Many candidates jump into a profitability analysis without first understanding how the company makes money. A subscription business, an ad-supported business, and a marketplace business have completely different economics. Always clarify the revenue model first.

 

  • Treating TMT as a different animal: Some candidates panic when they hear "telecom" or "streaming" because they think they need specialized technical knowledge. You do not. TMT cases test the same problem-solving skills as any other case. The industry context is a layer on top, not a replacement for fundamentals.

 

  • Forgetting about churn: In subscription businesses, churn is the silent killer. Candidates often focus on acquiring new customers and forget that a small increase in churn can wipe out all growth. According to McKinsey, reducing churn by just 1% can boost profits by 5% in telecom.

 

  • Using generic frameworks: Using a generic profitability or market entry framework without tailoring it to TMT misses the point. Add TMT-specific elements like network effects, switching costs, content economics, and regulatory factors.

 

  • Not connecting math to the objective: Calculating that churn costs $540 million is impressive math, but it only matters if you explain what the company should do about it. Always end your quantitative analysis with a "so what" that ties back to the recommendation.

 

Frequently Asked Questions

 

Are TMT case interviews harder than standard case interviews?

 

TMT case interviews are not inherently harder. They test the same core skills: structured thinking, quantitative analysis, business judgment, and communication. The main difference is that TMT cases require familiarity with industry-specific metrics and business models. If you spend a few hours learning TMT terminology and practicing two to three TMT-specific cases, you will be well prepared.

 

Do you need a technical background to pass a TMT case interview?

 

No. You do not need a computer science or engineering degree. TMT case interviews test business problem-solving, not technical skills. You need to understand how TMT companies make money and what their key metrics are, but you do not need to know how to code or build a network. According to Altman Solon, they hire candidates from a wide variety of academic backgrounds.

 

How many TMT practice cases should you do before your interview?

 

Aim for 3 to 5 TMT-specific practice cases on top of your general case preparation. Based on data from candidates who received offers at top firms, the ideal total is 15 to 25 practice cases overall, with a subset dedicated to the industries most relevant to your target firm. If you are interviewing at a TMT specialist like Altman Solon, do at least 5 TMT cases.

 

What is the best way to learn TMT industry knowledge quickly?

 

Start with the TMT metrics cheat sheet in this article. Then spend 30 minutes reading recent earnings call summaries from one company in each sector: a telecom carrier (like T-Mobile), a streaming platform (like Netflix), and a SaaS company (like Salesforce). Earnings calls use the exact language and metrics that appear in case interviews. This approach gives you practical industry knowledge in under two hours.

 

Can you use standard case frameworks for TMT cases?

 

Yes, but you should adapt them. A standard profitability framework (Revenue minus Costs) works perfectly for TMT as long as you break revenue into Subscribers x ARPU instead of just Units x Price. Similarly, a market entry framework works if you add TMT-specific factors like network effects, regulatory barriers, and infrastructure requirements. The framework structure is the same. The content within each bucket changes.
