How it works during a case interview

STEP 01

Interviewer gives the case prompt

Deepgram Nova-3 transcribes the case prompt in real time — supporting 36+ languages, before they even finish speaking.

STEP 02

QUICK box fires in 95ms

Groq delivers a concise framework — the right structure, key hypotheses, and clarifying questions to ask in 2–3 lines.

STEP 03

TECHNICAL box expands

GPT-4o Mini follows up with a full case structure — detailed analysis branches, math setup, and synthesis recommendation.

STEP 04

You answer confidently

Read from the overlay while maintaining eye contact. The interviewer sees nothing — the window is invisible on screen share.

Topics we cover

Every major case interview category — with example questions and the kind of answer you'll get.

Profitability Cases

Revenue vs cost breakdown, margin analysis, segmentation by product/region/customer, fixed vs variable cost isolation, and root cause identification.

Example Question

"Our client's profits dropped 20% — what happened?"

AI Response Preview

Structure: Profit = Revenue − Costs. Revenue = Price × Volume. Start by isolating which moved. Ask: is revenue down, costs up, or both? If revenue: which segment/product/region? Check pricing changes, volume decline, customer churn, competitive entry. If costs: fixed vs variable? Check raw material inflation, labor costs, one-time charges. Likely culprit: if volume is flat but profits dropped, look for cost increase — often raw material prices or a new facility driving up fixed costs.

Market Entry

Market sizing, competitive landscape analysis, entry mode (organic vs acquisition vs JV), regulatory barriers, go-to-market strategy, and financial viability.

Example Question

"Should our client enter the Indian market?"

AI Response Preview

Framework: (1) Market attractiveness — size ($XB), growth rate (X% CAGR), customer segments. India: 1.4B population, rising middle class, smartphone penetration 50%+. (2) Competitive landscape — local incumbents, global players already present, switching costs. (3) Entry barriers — regulatory (FDI rules, local partnership requirements), distribution infrastructure, cultural adaptation. (4) Entry mode — organic build (slow, full control), acquisition (fast, expensive), JV with local partner (shared risk, local expertise). (5) Financial case — investment required, break-even timeline (typically 3–5 years), target ROI vs other opportunities.

M&A / Due Diligence

Acquisition evaluation, synergy identification and sizing, valuation, integration risks, deal structure, and recommendation framework.

Example Question

"Should our PE client acquire this SaaS company?"

AI Response Preview

Evaluate across 4 dimensions: (1) Strategic fit — does it complement the portfolio? Cross-sell opportunities, technology synergies. (2) Financial health — ARR growth (>30% = strong), gross margins (>70% for SaaS), NDR (>110% = net expansion), CAC payback (<18 months). (3) Valuation — compare EV/ARR multiple to SaaS comps (typically 8–15x for growth SaaS). DCF with subscription revenue is more predictable. (4) Risks — customer concentration (top 10 clients <30% ARR), tech debt, key-person dependency, churn trends. Recommendation: proceed if NDR >110%, margins >70%, and price is below 12x ARR.

Pricing Strategy

Value-based pricing, competitive pricing, cost-plus analysis, price elasticity, bundling strategies, and pricing architecture.

Example Question

"How should we price a new product?"

AI Response Preview

Three approaches: (1) Cost-plus — calculate unit cost + target margin. Simple but ignores willingness to pay. (2) Competitive — benchmark against substitutes. If differentiated, price at premium; if commoditized, match or undercut. (3) Value-based — quantify the economic value to customer (time saved, revenue generated, cost avoided). Price at 20–30% of value delivered. Recommendation: start with value-based. Conduct conjoint analysis or Van Westendorp survey to find optimal price point. Consider tiered pricing (good/better/best) to capture different segments. Test with 5–10% of market before full rollout.

Operations / Process

Supply chain optimization, lean methodology, bottleneck analysis, capacity planning, quality improvement, and process redesign.

Example Question

"Our client's delivery times are 2x competitors — fix it"

AI Response Preview

Map the end-to-end process: order receipt → warehouse pick → packing → shipping → last-mile delivery. Identify bottleneck (Theory of Constraints). Common issues: (1) Warehouse — poor layout, manual picking vs automated. Solution: zone picking, wave planning, invest in WMS. (2) Shipping — suboptimal carrier contracts, no regional distribution. Solution: negotiate volume discounts, add a regional fulfillment center closer to demand clusters. (3) Last-mile — single carrier dependency. Solution: multi-carrier strategy, route optimization software. Quick wins: implement batch processing for orders, set up real-time tracking. Target: reduce delivery time by 40% within 6 months.

Behavioral for Consulting

Why consulting, leadership under pressure, teamwork, conflict resolution, client management, and structured STAR answers for MBB behavioral rounds.

Example Question

"Why consulting?"

AI Response Preview

Three pillars: (1) Variety and learning curve — I thrive on solving different problems across industries. In consulting, I'd work on a pricing strategy for a retailer one month and a digital transformation for a bank the next. No two projects are alike. (2) Impact at scale — consulting lets you work on problems that affect thousands of employees and millions of customers. My [specific experience] showed me the satisfaction of driving measurable business impact. (3) Collaborative problem-solving — the team-based case approach mirrors how I work best. At [specific example], I led a cross-functional team to [result], and I want to do that at scale with world-class teammates.
