Fictional practice, not an employer interview question.
Original exercise, not a reported employer interview question. A market-sizing exercise suggests a large opportunity, but the reachable customer segment may be much smaller. Design the next analysis.

A defensible response
Separate total demand from demand the proposed offering can serve and win. State the segment, access constraints, buying process, and competing alternatives. Build a transparent estimate from a few defensible drivers and stress-test the assumptions that matter most. Recommend one next research step or pilot that could overturn the thesis. Explain the operational requirements before proposing a full launch. A strong answer may narrow the opportunity substantially; that is better judgment than defending the largest number because it looks impressive.
Check your answer
Which customers are actually reachable? What evidence would make you recommend not entering the market?
Prepare your application
A large market is not the same as a reachable customer segment. Prepare a BCG case that tests the assumptions between those two numbers: buyer, need, access, economics and execution. A strong application makes your own analytical decisions visible, including the evidence that would make you recommend against the opportunity.
Choose your application route
Work to compare: Client-facing consulting or advisory; Data, digital, or technology delivery; Deals, audit, tax, risk, or specialist work; Project and program leadership; Research, knowledge, and internal functions.
Prepare one example: A case and impact packet with market or operational analyses, hypothesis trees, quantified leadership stories, and a clear office and practice thesis.
Ask the team: Which tradeoff involving strategy, digital and AI, or operations appears most often on the team?

Before applying: Check the vacancy’s degree or experience gate, term, worksite, pay basis and deadline. This is preparation guidance, not a verified 2027 internship list. A suggested work sample is not an application requirement.
Choose the work, then the evidence
Boston Consulting Group (BCG) is a global strategy and management consulting firm. That broad description hides very different teams and evidence standards. Start by identifying the role family, level, geography, work model, product or business area, and the operating problem behind the opening.
Read the job description twice. On the first pass, mark non-negotiable qualifications. On the second, underline repeated problem language such as strategy, digital and AI, operations, organization, climate and sustainability, industry practices. Repeated language can suggest priorities, but it does not prove the team's internal problem. Treat that interpretation as a hypothesis.
| Role family | High-signal proof |
|---|---|
| Client-facing consulting or advisory | Structured problem solving, hypothesis-driven analysis, executive communication, team contribution, and client implementation impact. |
| Data, digital, or technology delivery | Architecture or analytics depth plus the ability to turn technology into measurable client results within complex client transformations requiring analytical rigor, creativity, collaboration, and the ability to turn insight into action. |
| Deals, audit, tax, risk, or specialist work | Relevant technical standards, professional judgment, evidence quality, controls, and the ability to explain implications to non-specialists. |
| Project and program leadership | Workplan design, stakeholder alignment, issue escalation, team development, quality control, and quantified delivery outcomes. |
| Research, knowledge, and internal functions | Domain expertise, reusable intellectual capital, service mindset, and evidence that your work improved client or firm decisions. |
The table describes preparation choices, not six confirmed open job families.
Make one result inspectable
For the work described here, useful priorities are structured and creative problem solving, intellectual curiosity, team collaboration, client influence, measurable impact. Treat these as editorial preparation criteria, not an employer scoring system.
Weak: Analyzed market data and supported a growth strategy project.
Illustrative rewrite, not a real candidate result: Segmented a regional healthcare market using claims and referral data, identified a $120 million underserved opportunity, and co-designed a launch sequence adopted by the client leadership team.
Interview preparation and permitted tools
Follow the written invitation for the role, country and stage. Confirm the assessment format, permitted tools and any rules on AI assistance; keep restricted tasks independent. Use only public or authorized material in a work sample. Be ready to explain the method, a failed assumption and your own contribution.
