Fifty pages of material.
Five slides.
One recommendation.
MBA candidates see that setup and often feel strangely comfortable.
You have built decks before.
That comfort can be expensive.
A presentation case is not primarily testing whether you can make attractive slides.
It is testing whether you can decide what deserves to survive.
The first slide mistake happens before PowerPoint opens
You read the packet.
Then you read it again.
Then you highlight more.
Soon, everything feels important.
That is exactly the problem.
A consultant does not win by showing the client how much material they reviewed. The client needs the pieces that change the decision.
Compression begins with exclusion.
Suppose the client is deciding whether to launch a new service.
The packet contains market growth, customer research, competitor profiles, operational constraints, financial projections, and implementation risks.
All useful.
But not equally useful.
Ask one question first:
What must be true for me to recommend launch?
Now the material starts competing for space.

Your MBA deck habits help... until they become decoration
Business school teaches presentation.
Titles. Exhibits. Story flow. Appendix. Clean formatting.
Good.
But a polished five-slide deck with no point of view is still weak.
Each slide should earn its place by moving the decision forward.
| Weak slide purpose | Stronger question | What changes |
|---|---|---|
| “Market overview” | Is the market attractive enough to matter? | The slide needs a conclusion |
| “Customer data” | Which customers actually drive the opportunity? | Segmentation becomes selective |
| “Financial analysis” | Does the economics clear the decision threshold? | Only decision-relevant numbers survive |
| “Risks” | What could reverse our recommendation? | Risks become prioritized |
Notice the difference.
The second column creates tension.
The third forces a point of view.
A slide is not a storage unit.
Then the clock starts changing your standard
Under normal MBA conditions, you may spend 20 minutes making one chart cleaner.
In a written case, those 20 minutes could be the difference between having a recommendation and having four beautiful slides plus an unfinished fifth.
That means your normal quality standard needs a temporary rewrite.
Correct beats beautiful.
Clear beats clever.
Complete beats ornamental.
And once those are secured, polish what the remaining time allows.
This can feel uncomfortable if you are used to presentation grades or team decks that were revised six times before class.
The interview is testing a different environment.
Five slides does not mean five separate analyses
This is another trap.
Candidates sometimes treat each slide as a mini-assignment.
Market.
Customers.
Competitors.
Financials.
Recommendation.
Logical.
But the story can become a stack rather than an argument.
Instead, ask whether slide two changes what slide one made you believe.
Does slide three narrow the opportunity?
Does slide four test whether it is economically viable?
Does slide five tell the executive what to do next?
The slides should move, not accumulate.
If you want to practise even more aggressive synthesis, One-Slide Case Interview: Structuring Under Extreme Time Pressure takes the same skill to its logical extreme.
The final five minutes reveal what you really prioritized
Imagine the timer is nearly done.
One chart is ugly.
Another title is vague.
Your recommendation is still missing the main risk.
What gets your attention?
The temptation is visual cleanup because it feels controllable.
Do not hide there.
Fix the recommendation.
Fix the answer-first titles.
Fix the missing implication.
Then align the boxes.
Because the client will forgive a slightly imperfect slide.
They will not forgive reaching slide five and still wondering what you think.
Fifty pages was never the real challenge.
Choosing the five things worth saying was.
