Practice scoring, leaderboards, and GD briefs require a free account. For candidates in the United States and Europe recruiting for consulting (McKinsey, BCG, Bain and other strategy firms), finance and strategy roles, MECE's international site is https://www.mece.in/us: AI case interview and market sizing practice set in US markets, priced in US dollars and euros, with free guides at https://www.mece.in/us/learn. ## Core pages - [Home](https://www.mece.in/): what MECE is and how scoring works - [The MECE framework](https://www.mece.in/learn/mece-framework): the definitive reference on the MECE principle (Mutually Exclusive, Collectively Exhaustive) — meaning, pronunciation, Barbara Minto's authorship, 12 worked examples, the 6 ways to build a MECE split, the GRIPS test, common mistakes, documented criticisms, and cited primary sources - [Scoring methodology](https://www.mece.in/methodology): the 6-dimension rubric behind every score - [About](https://www.mece.in/about): the team behind MECE - [Sign up](https://www.mece.in/signup): free account ## MECE for the US and Europe MECE's international site (https://www.mece.in/us) is case interview practice for candidates recruiting for consulting, finance and strategy roles in the United States and Europe. An AI interviewer runs consulting cases and market sizing questions set in US markets, answers clarifying questions, pushes back on structure, and scores each attempt out of 100 on six dimensions (structure 25, quantitative skills 20, synthesis and communication 20, business judgment 15, creativity 10, presence 10) in about a minute. - [MECE — AI case interview practice (US)](https://www.mece.in/us): what it is, how scoring works, free daily case - [Pricing (US dollars / euros)](https://www.mece.in/us/pricing): Free; Lite $29/month or $69 for 3 months; Pro $49/month or $119 for 3 months; the same numbers in euros in Europe; one-time payments, no auto-renewal - [50 case interview examples](https://www.mece.in/us/case-interview-examples): profitability, market entry, M&A, pricing, growth, operations, cost reduction, go-to-market and competitive strategy cases - [50 market sizing questions](https://www.mece.in/us/market-sizing-questions): US guesstimate questions with scope, from warm-up to final-round difficulty ## MECE Learn (US and Europe): free guides to business problem solving MECE (mece.in) is an AI practice platform for case interviews and business problem solving, named after the consulting principle Mutually Exclusive, Collectively Exhaustive. It is not affiliated with McKinsey or any other consulting firm. - [MECE Learn hub](https://www.mece.in/us/learn): Free guides to MECE thinking, case interviews, market sizing and business frameworks, plus role guides for product, sales, marketing, HR, operations and finance. - [What is MECE? The principle behind structured problem solving](https://www.mece.in/us/learn/what-is-mece): MECE stands for Mutually Exclusive, Collectively Exhaustive. It is a rule for breaking a problem into parts that do not overlap (mutually exclusive) and that together cover every possibility (collectively exhaustive). Barbara Minto named it at McKinsey in the late 1960s. Consultants and managers use it to structure analyses and recommendations. - [Case interviews: how they work and how to prepare](https://www.mece.in/us/learn/case-interview): A case interview is a 20–40 minute business problem you solve out loud with an interviewer. You clarify the question, lay out a structure, analyze data and do the math, then recommend what the client should do. Consulting firms and many strategy, product and operations teams use cases to see how you think under pressure. - [Issue trees: how to break down any business problem](https://www.mece.in/us/learn/issue-trees): An issue tree is a diagram that breaks one business question into smaller questions, level by level, so each branch can be analyzed on its own. Every level should be MECE: no overlaps and no gaps. Diagnostic trees ask why something happened. Solution trees ask how to fix it or reach a goal. - [Market sizing questions: the method, US numbers and a worked example](https://www.mece.in/us/learn/market-sizing): A market sizing question asks you to estimate a number you cannot look up, like how many coffee shops operate in the US. Clarify exactly what is being counted, pick a structure (top-down from population, or bottom-up from supply), put a number on every assumption, multiply through, then sanity-check the result against something you know. - [Case interview math: the formulas and shortcuts you need](https://www.mece.in/us/learn/case-interview-math): Case interview math is business arithmetic done out loud, usually without a calculator: percentages, margins, break-even, growth rates, and simple payback or NPV. You need about ten formulas, clean rounding, and the habit of saying what each result means for the client. Speed comes from daily practice, not advanced math. - [The Pyramid Principle: how to give a clear recommendation](https://www.mece.in/us/learn/pyramid-principle): The Pyramid Principle structures communication with the answer at the top, a few grouped reasons beneath it, and data beneath each reason. Barbara Minto developed it at McKinsey. In a case interview it shapes your final recommendation: say what the client should do first, then why, then the risks and next steps. - [The profitability framework for case interviews](https://www.mece.in/us/learn/profitability-framework): The profitability framework breaks profit into revenue and costs, then revenue into price and volume, and costs into variable and fixed. Use it to find why profit changed and what to do about it: let the numbers show which branch moved, then look for the business reason behind the number. - [The market entry framework: should we enter, and how?](https://www.mece.in/us/learn/market-entry-framework): The market entry framework answers two questions: should a company enter a new market, and if so, how? Assess the market (size, growth, profitability), the competition, the company's ability to win, and the economics of entering. Then choose an entry mode: build it yourself, buy a player, or partner. - [Pricing strategy framework: how to set a price in a case](https://www.mece.in/us/learn/pricing-strategy-framework): Pricing cases ask what a company should charge. Use three lenses: cost sets the floor, competitors set the reference, and customer value sets the ceiling. Price somewhere between the floor and the ceiling, then check how volume, competitors and the brand will respond before recommending a number. - [Growth strategy framework: how a company can grow revenue](https://www.mece.in/us/learn/growth-strategy-framework): A growth strategy case asks how a company can grow revenue. Structure the options as growing the core (more customers, more revenue per customer), expanding (new segments, geographies, channels or products) and buying or partnering. Size each option, weigh its risk and fit, and recommend a focused combination that closes the growth gap. - [M&A and private equity case interviews: how to evaluate a deal](https://www.mece.in/us/learn/mergers-and-acquisitions-case): An M&A case asks whether a company or investor should buy a target. Check four things: whether the target's market is attractive, whether the target itself is strong, what it is worth compared with the price (including synergies), and whether the deal can be executed and integrated. Then recommend buying, walking away or negotiating a lower price. - [Go-to-market strategy framework: how to launch a product](https://www.mece.in/us/learn/go-to-market-framework): A go-to-market (GTM) framework plans how a product reaches customers: who to target first, what problem and message will win them, how to price, which channels to sell through, and which metrics show it is working. In a case, size the opportunity, pick a beachhead segment, and check the launch economics before recommending a plan. - [Cost reduction framework: where to cut, and what to protect](https://www.mece.in/us/learn/cost-reduction-framework): A cost reduction case asks where a company can cut costs without hurting what customers value. Map the full cost base, benchmark each bucket against competitors or history, then choose levers: pay less for what you buy, use less of it, work more efficiently, or stop doing low-value work. Size each lever against the target. - [Operations case interviews: capacity, bottlenecks and process](https://www.mece.in/us/learn/operations-case-framework): Operations cases ask why a process is too slow, too costly or too unreliable, and how to fix it. Map the process step by step, find the bottleneck (the step with the least capacity), measure throughput, cycle time, utilization and quality, then fix the constraint first. Improving any other step will not raise output. - [Competitive response framework: what to do when a rival moves](https://www.mece.in/us/learn/competitive-response-framework): A competitive response case asks how a company should react when a rival moves: a new entrant, a price cut or a new product. First understand the threat: which customers are affected, how much revenue is at risk and why customers might switch. Then compare responses such as matching, differentiating, focusing on a niche or holding steady. - [Business frameworks explained: Porter's Five Forces, SWOT, 4Ps and more](https://www.mece.in/us/learn/business-frameworks): Business frameworks are reusable checklists for analyzing a situation: Porter's Five Forces for industry attractiveness, the 3Cs for strategy, the 4Ps for marketing, SWOT for a quick position check, and others. Use them as starting points that make your thinking complete, then tailor the buckets to the specific problem instead of reciting them. - [Product manager case interviews: estimation, metrics and product sense](https://www.mece.in/us/learn/product-manager-case-interview): Product manager interviews use cases to test how you think about users, products and numbers. Expect estimation questions, metric diagnosis ("a key metric dropped 8%, why?"), product design ("improve this product for a user group") and strategy ("should we build X?"). The same structured, MECE approach consultants use works for each. - [Sales case interviews: quota, pipeline and territory problems](https://www.mece.in/us/learn/sales-case-interview): Sales interviews, especially for managers, often include a business case or a role-play: diagnose a missed quota, plan a territory, prioritize accounts or handle a pricing objection. Break bookings into opportunities × win rate × average deal size, find the weak driver, and recommend actions with numbers, just as you would in a consulting case. - [Marketing case interviews: segmentation, funnels and ROI](https://www.mece.in/us/learn/marketing-case-interview): Marketing case interviews test how you grow demand profitably: which customers to target, what to say to them, which channels to use, and whether the spend pays back. Structure answers around segmentation, targeting and positioning, the funnel from awareness to repeat purchase, and unit economics such as customer acquisition cost and lifetime value. - [HR case interviews: attrition, workforce planning and org design](https://www.mece.in/us/learn/hr-case-interview): HR and people case interviews test whether you can solve workforce problems with the same rigor as business ones: why attrition rose, how many people to hire, how to design an organization, or how to structure pay. Break the problem down MECE, put numbers on it (the cost of turnover, the headcount gap), find the root cause and recommend targeted fixes. - [Strategy and operations (BizOps) interviews: cases and how to prepare](https://www.mece.in/us/learn/strategy-and-operations-interview): Strategy and operations roles, also called BizOps or chief of staff roles, hire people who can diagnose a business problem, size it and drive the fix across teams. Interviews mix live cases (why did a metric move, should we launch X), take-home analyses with real data, and questions about prioritizing and running projects. Structured thinking and clean math matter most. - [Finance case interviews: variance analysis, business cases and valuation](https://www.mece.in/us/learn/finance-case-interview): Finance case interviews for FP&A, corporate finance and corporate development roles test whether you can turn numbers into a business decision: explain a budget variance, build the business case for an investment, or judge whether an acquisition creates value. Expect margin math, NPV and payback, variance analysis, and a clear recommendation. ## Getting Started - [What a case interview tests](https://www.mece.in/learn/casebook/getting-started/what-it-tests): Five things, graded at once, in real time.
