Mock Interview

Case interview

Structured problem decomposition and business judgment.

Mock mode

Overview

The case interview presents a business problem to solve aloud. It measures structured problem-solving, quantitative reasoning, and how you drive toward a recommendation with a hypothesis-led framework.

Step by step, with examples

  1. 1

    Structure

    • Break the problem into MECE buckets.
  2. 2

    Data/math

    • Do the math out loud.
  3. 3

    Hypothesis

    • Drive toward an answer.
  4. 4

    Synthesis

    • Give a clear recommendation.
    • Example: profit = R − C

What it tests

Structured problem decomposition and business judgment.

Format & timing

30–40 min · interviewer-led or candidate-led case.

Sample questions

  • Our client's revenue dropped 20% — how would you diagnose it?
  • Should this retailer enter a new market?
  • How many electric cars will sell in this country next year?

Model-answer walkthrough

  • Clarify the objective and success metric.
  • Lay out a MECE structure (e.g., revenue = volume × price).
  • Form a hypothesis and ask for the data to test it.
  • Synthesize into a clear recommendation with a 'so what'.

What good looks like

  • Clear, MECE structure
  • Hypothesis-driven
  • Comfort with quick math
  • Decisive recommendation

Likely follow-ups

  • What's the risk of your recommendation?
  • What data would change your mind?
  • How would you implement it?

Common mistakes

  • No framework
  • Boiling the ocean
  • Analysis with no recommendation
  • Math errors under pressure

Pre-round checklist

  • Drill 5–10 cases
  • Practice mental math
  • Have 2–3 frameworks ready to adapt
