The Case Interview
The case interview is the defining feature of consulting recruitment. You'll be given a business problem to solve in real time, demonstrating structured thinking.
Types of Cases
- Market sizing: "How many pianos are sold in Singapore each year?"
- Business situation: "Your client's profits have fallen 20%. Why and what do you recommend?"
- M&A: "Should Company A acquire Company B?"
- Operations: "How can our client reduce delivery time by 30%?"
The MECE Framework
Good consultants think in a Mutually Exclusive, Collectively Exhaustive structure. Every answer should:
- Break the problem into non-overlapping parts
- Cover all relevant dimensions
- Be logically complete
Case Frameworks
You don't memorise frameworks — you adapt them. Common starting points:
- Profitability: Revenue vs Costs → drill down on each
- Market entry: Market attractiveness + competitive position + financials
- Growth strategy: Existing markets vs new markets, existing products vs new products
Practice Resources
- CaseCoach (used by NUS/NTU consulting clubs)
- PrepLounge — case practice with partners
- Case in Point (book by Marc Cosentino)
- Your university's consulting club — most run weekly case prep sessions
The Fit Interview
Alongside cases, you'll face behavioural questions. Consulting firms test:
- Leadership: "Tell me about a time you led a team through conflict"
- Impact: "What's your most significant achievement?"
- Analytical thinking: "Walk me through a data-driven decision you made"
- Why consulting / why this firm: Critical — do your research
For Why MBB questions:
- Know 2–3 recent case studies published by the firm in Singapore/SEA
- Name specific practice areas you're interested in
- Reference the firm's culture accurately (McKinsey: problem-solving rigour; BCG: innovation and diversity; Bain: "results, not reports")
What the Internship Actually Looks Like
Week 1–2
- Onboarding and case team assignment
- Meet your team: Analyst, Associate/Consultant, Manager, Partner
- Begin structuring the client problem
Weeks 3–8
- Conduct research (expert interviews, data analysis, benchmarking)
- Build slide decks and models
- Weekly client check-ins
- Receive constant feedback from your manager
Final 2 Weeks
- Final deliverable preparation
- Presentation to client (interns often present a section)
- Evaluations and potential offer conversations
Reality Check
Consulting internships are intense. Expect:
- 60–70 hour weeks during crunch periods
- Continuous feedback (including critical)
- High standards for slide quality and analysis
- A fast, steep learning curve
Offer Conversion
MBB conversion rates for interns vary. Roughly 40–60% of interns at top firms receive return offers, depending on performance and headcount. Standing out means:
- Proactively structuring problems without being asked
- Communicating clearly — both in writing and verbally
- Showing intellectual curiosity beyond your workstream
- Building rapport with the client team
Final Tips
- Start case prep 3–4 months early — you need 50+ practice cases
- Join your university consulting club — NUS Consulting Group, NTU Business Case Club, SMU Case Consulting Group
- Do mock interviews with real consultants — cold-message MBB analysts on LinkedIn
- Read business news daily — Economic Times, Business Times, FT
- Apply to all tiers simultaneously — MBB, Oliver Wyman, and Big 4 at the same time
