Kearney Case Interview: Process, Official Case and Worked Practice

A Kearney case interview tests how you work through an unfamiliar business problem and explain a recommendation. Prepare both your analysis and your discussion of past experiences. Start with the firm's own materials, then practise a fresh case so you can check whether your reasoning transfers.

This guide combines Kearney's current recruiting guidance, an official practice case and an original packing-line exercise with worked calculations. The exercise is fictional and is not a Kearney interview question. Process information was checked on October 1, 2026; your recruiter and invitation determine the format for your role and location.

What is Kearney's interview process?

Kearney's global recruiting page describes a mix of behavioral and case interviews for general consulting. Its typical process has four to five interviews, with possible additional competency assessment depending on the role. Specialist and internal positions have different arrangements.

Before planning practice, ask your recruiter which stages apply, whether you will receive exhibits or preparation material, and whether there is a written, group or other assessment. The general page does not establish one universal interview length or a written stage for every candidate.

The case is a conversation about a decision. Being able to name a framework is less useful than explaining why a particular analysis would help the client.

Use Kearney's official case before buying more material

Kearney provides case preparation guidance and a promotional-planning practice case. The latter concerns a grocery and drug-store retailer with disappointing promotional sales. Its answer guidance connects product availability and planning processes to missed sales.

Work through the prompt before opening the answer guidelines. Write down what you would clarify, your initial hypothesis and the evidence that would distinguish it from another explanation. Then compare your approach with the firm's discussion. An official example helps you understand the task; it does not predict the problem you will receive.

Our suggested review questions are: Did I diagnose a cause before recommending a solution? Did I confuse observed sales with underlying demand? Did I consider how people would implement the change? These are our practice questions, not an official scoring rubric.

A practical approach to the Kearney case interview

Use a structure that fits the client's question. Kearney's preparation guidance emphasizes listening, logical reasoning, testing hypotheses and communicating clearly. It cautions against forcing a standard framework onto every problem.

1. Clarify the decision. Ask what the client wants to achieve, over what period and subject to which constraints. Restate the objective in one sentence.
2. Identify the main possibilities. Build a small set of explanations relevant to this problem. Say which you would test first and why.
3. Request useful evidence. Ask for information that could change the decision. Explain what you will do with it.
4. Calculate and interpret. State units, show the calculation and explain the business implication. A number alone is not a recommendation.
5. Update the hypothesis. If the evidence contradicts your initial view, change direction explicitly.
6. Recommend a next step. Tie it to the evidence, identify a material risk and name the test or action that should happen next.

For broader examples, use the case interview practice collection. Keep this guide for Kearney's own materials and the exercise below.

Original practice case: should a packing line reduce changeover time?

Fictional prompt: A packaged-food manufacturer wants to fulfil 3,600 cartons per day without buying a second packing line. Its current line misses that target. Should it invest in a changeover improvement, outsource the shortfall or reconsider the target?

First ask whether 3,600 means saleable cartons, what the time horizon is, whether demand is supported by orders, and whether there are constraints on safety, quality or staffing. For this exercise, the target is saleable cartons per working day. Assume confirmed demand, one 480-minute shift and enough upstream product and warehouse capacity. All financial amounts are illustrative dollars in a single currency.

Exhibit 1: production assumptions

The proposal costs $90,000 upfront and $15,000 annually to maintain. The plant operates 250 days per year. Each additional carton produced in-house rather than outsourced saves $1.20 after all relevant incremental in-house costs. Outsourced cartons are available at the required quality, and the supplier charges no fixed fee in this simplified example.

Pause and calculate the current shortfall, the proposed line's capacity, the annual net savings and simple payback. Then decide which assumption you would test first.

Step 1: calculate current saleable capacity

Current running time is 480 − 60 − (4 × 30) = 300 minutes.

Saleable output is 300 × 12 × 95% = 3,420 cartons per day.

The gap to the target is 3,600 − 3,420 = 180 cartons per day. The line is close to the target, so a major capital expansion would need a stronger justification than “we have a capacity problem.”

Step 2: test the improvement against the target

Proposed running time is 480 − 60 − (4 × 15) = 360 minutes.

Saleable capacity becomes 360 × 12 × 95% = 4,104 cartons per day, which exceeds the target by 504. The capacity gain is 684, but only 180 additional cartons have value under the stated demand. Do not credit savings on all 684 unless you establish demand or another benefit.

The current operation needs 3,600 ÷ (12 × 95%) ≈ 315.8 running minutes to reach its target. With 420 minutes available after breaks and cleaning, total changeover time must be no more than about 104.2 minutes, or approximately 26.05 minutes per changeover. Use the unrounded value when testing a borderline result. A less expensive improvement might therefore be sufficient.

Step 3: calculate savings and payback

Avoided outsourcing is 180 × 250 = 45,000 cartons per year.

Gross annual savings are 45,000 × $1.20 = $54,000.

After annual maintenance, net recurring savings are $54,000 − $15,000 = $39,000.

Simple payback is $90,000 ÷ $39,000 ≈ 2.31 years. This calculation excludes tax, discounting, ramp-up, downtime and any other costs not supplied. It is not a full investment valuation.

Step 4: challenge the recommendation

Suppose a pilot reaches only 27 minutes per changeover. Running time would be 480 − 60 − (4 × 27) = 312 minutes, producing 312 × 12 × 95% = 3,556.8 saleable cartons per day on average. That remains below target.

The proposal should therefore be tested against saleable output and reliable changeover performance. Safety and quality requirements stay fixed; rushing cleaning to save time would not be a valid solution.

A reasonable provisional recommendation is to pilot a lower-cost changeover improvement, compare its reliable output with the target, and keep outsourcing as cover during testing. The $90,000 option may make sense if its performance and net savings hold over a sufficiently long horizon. A demand drop, yield decline or implementation cost could change that decision.

Example recommendation

“My current estimate is a shortfall of 180 saleable cartons per day. The proposed improvement would close it, but much of its extra capacity has no value at current demand. Its simplified payback is about 2.3 years. I would compare a smaller improvement with the full proposal, validate quality and output in a pilot, and retain outsourcing while we test.”

This is one defensible conclusion under the fictional assumptions. A different recommendation can work if it explains the objective, evidence and trade-offs.

Four follow-up questions for a practice partner

Have the partner change one input without telling you which calculation to use:

• Confirmed demand falls to 3,300 cartons per day. Is there still an outsourcing saving?
• Saleable yield drops after faster changeovers. What yield is needed to meet 3,600 at 360 running minutes?
• The improvement disrupts production for several days. Which cash-flow and service effects must be added?
• A supplier offers a lower outsourcing price. How does that change the relative savings and payback?

For the second question, 3,600 ÷ (360 × 12) is about 83.3%. That is the arithmetic threshold in this exercise, not an acceptable quality standard. Product safety, specification compliance and operational resilience require separate judgment.

You can practise the underlying calculation with the capacity planning guide or the break-even examples. Then return to a fresh case so the exercise does not become a memorized routine.

Prepare behavioral answers for Kearney

Prepare a few real experiences showing a difficult choice, teamwork, disagreement, learning from feedback and responsibility for an outcome. Explain the setting briefly, distinguish your actions from the team's actions and discuss what you learned.

For “Why Kearney?”, connect a verified aspect of the role or office to your interests and an experience that supports them. Do not substitute praise for an explanation of fit. If a particular project or sector attracts you, research it and be ready to explain why.

Try these original prompts with a partner: “When did you change your mind because of evidence?” “How did you respond when a teammate disagreed?” “What did you learn from a result you could not fully control?” Use the consulting behavioral question guide for more practice.

Choose the next practice task from your last mistake

If your calculation was wrong, repeat the arithmetic with new numbers. If you asked for irrelevant data, explain which decision each request supports. If your conclusion ignored a risk, practise a short recommendation that includes it.

Frequently asked questions

Are Kearney cases always about operations?

The official promotional-planning example has an operational cause, and our exercise uses capacity. Neither establishes that every interview will be an operations case. Prepare to reason through different business decisions.

Is every Kearney case candidate-led?

The global recruiting guidance checked for this article does not specify one universal case-control format. Practise proposing sensible next steps while responding to the interviewer's questions and new information.

Do I need a memorized framework?

Use a structure suited to the objective. A memorized list can make you miss the relevant cause. Explain why each branch matters and change it when the facts change.

How should I use official examples and AI practice together?

Solve official materials independently, review the reasoning and practise a different problem aloud. Follow your recruiter's assessment rules. Use AI only for permitted preparation, and do not use outside assistance during an actual interview or assessment.
