How to Give a Strong Recommendation in a Case Interview When the Data Is Inconclusive

A case interview does not always give you enough information to produce a perfectly certain answer. You may have conflicting data, missing information, competing options, or risks that cannot be completely quantified. Some candidates respond by becoming overly cautious and saying they need more information before making a decision. Others become overly confident and ignore the uncertainty. A strong recommendation sits between these extremes: it makes a clear decision based on the available evidence while acknowledging important risks, assumptions, and next steps.

Key Takeaways

• A recommendation doesn’t require perfect information.
• Lead with a clear answer instead of summarising the entire case.
• Support your recommendation with the strongest evidence.
• Acknowledge important risks without weakening your decision.
• Explain what you would investigate or do next.
• Confidence and uncertainty can coexist.

The Goal Is a Decision, Not Perfect Certainty

Consultants rarely operate with complete information.

A client may need to decide whether to:

• Enter a market
• Launch a product
• Acquire another company
• Increase prices
• Expand capacity
• Reduce costs
• Change a distribution strategy

Waiting until every variable is known could mean missing the opportunity entirely.

That’s why consulting recommendations often involve informed judgment.

The question isn’t:

“Can I prove this decision is 100% correct?”

It’s:

“Based on the evidence available, which option is most attractive and why?”

That distinction is critical in case interviews.

Start With the Answer

When the interviewer asks:

“What would you recommend?”

Don’t begin with five minutes of background.

Lead with the decision.

For example:

“I recommend that the client enter the market, provided it can achieve the required customer acquisition economics.”

Then explain why.

A strong recommendation typically follows:

Answer → Supporting reasons → Evidence → Risks → Next steps

This makes your conclusion easy to understand.

Support Your Recommendation With the Strongest Evidence

You don’t need to repeat every calculation from the case.

Choose the two or three findings that matter most.

For example:

“I recommend entering the market for three reasons. First, the market is growing rapidly. Second, our analysis suggests the client can achieve attractive unit economics. Third, the client has an existing distribution advantage. The main risk is customer acquisition cost, which I’d want to validate before committing significant investment.”

This is concise but comprehensive.

It demonstrates that you can distinguish important evidence from supporting detail.

What If Two Options Look Equally Attractive?

Sometimes the data doesn’t clearly identify a winner.

Don’t pretend otherwise.

Instead, compare the options across the factors that matter most to the client.

For example:

You can then make a recommendation based on the client’s priorities.

For example:

“Although Option A offers greater financial upside, I’d recommend Option B because the client prioritises predictable growth and has limited implementation capacity.”

This shows that recommendations depend on decision criteria, not just one number.

Explain the Trade-Off

Strong business decisions often involve trade-offs.

A recommendation becomes more credible when you acknowledge them.

For example:

“The expansion offers attractive growth potential, but it requires significant upfront investment. Given the client’s strong balance sheet and long-term growth objective, I believe the upside outweighs the investment risk.”

You’re not ignoring the downside.

You’re explaining why the upside is still compelling.

That is business judgment.

Don’t Say “It Depends” Without Making a Decision

“It depends” can sometimes be appropriate.

But it should not replace a recommendation.

Weak:

“It depends on the market conditions.”

Stronger:

“I’d recommend entering the market under the assumption that customer acquisition costs remain below the level required to achieve our target margin. If acquisition costs exceed that threshold, I would delay the launch.”

The second answer still acknowledges uncertainty.

But it provides a decision rule.

Use Conditional Recommendations When Necessary

A conditional recommendation can be especially useful when one unresolved variable could materially change the decision.

For example:

“I’d recommend proceeding, provided the company can secure the required supplier capacity. If capacity cannot be secured within the next six months, I’d pursue the alternative expansion plan.”

This demonstrates that you understand what could change the recommendation.

It also shows that you’ve identified the critical uncertainty rather than simply listing every possible risk.

Distinguish Important Risks From Minor Risks

You don’t need to list ten risks at the end of your case.

Focus on the risks that could genuinely change the decision.

Ask:

• What assumption is most important?
• What could make the recommendation fail?
• What information is still missing?
• How difficult would it be to mitigate the risk?

For example, if you’re recommending market entry, a minor branding concern may not matter as much as whether the economics work.

Prioritise accordingly.

Explain the Next Steps

A recommendation shouldn’t necessarily be the end of the conversation.

Tell the interviewer what you would do next.

For example:

“My next step would be to validate customer acquisition costs through a small-scale pilot before committing to a full market launch.”

This makes your recommendation practical.

Other possible next steps include:

• Customer research
• Pilot testing
• Supplier negotiations
• Competitor analysis
• Financial validation
• Regulatory review
• Operational feasibility assessment

The best next step is usually the one that resolves the most important uncertainty.

Don’t Introduce New Analysis at the End

Your final recommendation should synthesise the case—not suddenly introduce a completely new argument.

If your recommendation depends on a factor that you never analysed, the interviewer may question where it came from.

Your conclusion should feel like the natural result of your analysis.

Think of the case as a story:

Problem → Analysis → Evidence → Insight → Decision

The recommendation is the conclusion of that story.

Communicate Confidence Without Overconfidence

There’s a difference between confidence and certainty.

You can say:

“Based on the evidence available, I recommend…”

This is confident.

You don’t need to say:

“This will definitely succeed.”

Business decisions rarely have guarantees.

A professional recommendation recognises uncertainty while still making a decision.

This is particularly important when the data is inconclusive.

What If the Interviewer Challenges Your Recommendation?

Be prepared to defend the logic behind it.

Suppose the interviewer asks:

“What would make you change your recommendation?”

A strong response could be:

“The most important factor would be customer acquisition economics. If our expected acquisition cost is materially higher than our current estimate, the projected returns would decline significantly and I’d reconsider the investment.”

Now you’ve identified the variable that matters most.

If the interviewer asks:

“What is your biggest concern?”

Don’t list five.

Choose one.

That demonstrates prioritisation and conviction.

A Simple Recommendation Formula

A useful structure is:

1. Recommendation

State your decision clearly.

2. Three Reasons

Give the strongest supporting arguments.

3. Evidence

Reference the most important findings from your analysis.

4. Risks

Mention the key uncertainty or downside.

5. Next Step

Explain how you would validate or execute the decision.

For example:

“I recommend that the client expand into the market. The decision is supported by strong market growth, attractive economics, and the client’s existing distribution capabilities. The main risk is customer acquisition cost, so I’d validate that through a pilot before scaling. If acquisition economics meet our target threshold, I’d proceed with the full expansion.”

This structure is concise, logical, and commercially relevant.

Avoid These Recommendation Mistakes

1.Giving a vague answer

Don’t make the interviewer guess what you recommend.

2.Repeating the entire case

Your recommendation should synthesise, not recap everything.

3.Ignoring trade-offs

Every major decision has advantages and disadvantages.

4.Listing too many risks

Focus on the risks that could actually change the decision.

5.Introducing new information

Your recommendation should be grounded in the analysis.

6.Refusing to decide

Incomplete information doesn’t mean you cannot make an informed recommendation.

7.Sounding overly certain

Confidence is good. Unjustified certainty isn’t.

Practice Making Decisions With Incomplete Information

One of the best ways to improve recommendations is to practise cases where the answer isn’t obvious.

After solving a case, ask yourself:

• What would I recommend?
• Which evidence supports that decision?
• What is the biggest risk?
• What assumption matters most?
• What information would change my decision?
• What should the client do next?

This forces you to move beyond analysis into decision-making.

A strong case interview recommendation doesn’t require perfect data.

It requires clear judgment.

When the evidence is incomplete, make the best decision supported by what you know, explain the reasoning behind it, acknowledge the most important uncertainty, and identify the next step that can reduce that uncertainty.

The strongest candidates don’t hide uncertainty.

They manage it.

And they don’t simply tell the interviewer what the data says.

They explain what the client should do about it.

Frequently Asked Questions

1. How do you give a strong recommendation in a case interview?

Start with a clear answer, support it with the strongest evidence from your analysis, acknowledge the most important risk, and explain the next step.

2. What if the data is inconclusive?

Make a recommendation based on the strongest available evidence and clearly state the assumption or uncertainty that could change your decision.

3. Should I say “it depends” in a case interview?

Only when the decision genuinely depends on an unresolved variable. If you use “it depends,” explain the specific condition and still provide a preferred course of action.

4. How many reasons should I give for my recommendation?

Two or three strong reasons are usually more effective than a long list. Prioritise the arguments that have the greatest impact on the client’s decision.

5. What makes a case interview recommendation persuasive?

A persuasive recommendation is clear, evidence-based, commercially relevant, and practical. It explains not only what the client should do, but also why, what the key risk is, and what should happen next.
