Presentation Exercise: Assessment Centre Practice and Tips

Almost everyone brings too much

The most reliable prediction anyone can make about an assessment centre presentation is this: the candidate has prepared somewhere between 2 and 3 times more content than the slot can hold, and will spend the last 90 seconds speeding up.

It is an understandable mistake. Preparation feels like coverage — the more ground you have covered, the more prepared you feel. But a 5 minute talk delivered at a sustainable pace is about 650 words. That supports 2 or 3 genuine points with evidence, and nothing else. A 10 minute slot is around 1,300 words, which sounds like a lot and disappears the moment you try to explain a business case from first principles.

So the first and most valuable decision in any presentation exercise is subtractive. What are the 2 things, and what is the 1 thing you will say first?

There is a stronger claim worth making here, and it is the one most preparation advice avoids: the content of your recommendation matters much less than you think. Assessors are scoring structured communication, reasoning made visible, and composure under challenge. They are rarely scoring whether you picked the option they would have picked. Candidates who agonise over choosing the "right" recommendation during a 30 minute prep window are optimising the wrong variable — and then arriving with 4 unstructured points instead of 2 clean ones.

What presentation exercises measure

Typically: verbal communication, structure and clarity of thought, influencing and persuasion, analytical reasoning, composure under pressure, and — during the questions — the ability to hold or revise a position on evidence rather than on social pressure.

The indicators assessors write against tend to be mechanical and specific: did the candidate state a conclusion before supporting it? Was the structure signposted so the audience could follow? Did they finish inside the time? Did they engage with the actual question asked, or the question they had prepared for? Did they distinguish between what the data showed and what they inferred from it?

Note what is not on that list: charisma, slide design, memorised fluency. A softly spoken candidate with a clear structure reliably outscores a polished one with none. And note something easy to miss — finishing inside the time is frequently an explicit indicator, not a courtesy. Overrunning is not enthusiasm on the sheet; it is a failure of planning.

Common formats

Prepared in advance. A title sent 3 days to 7 days before the centre. Expectations rise accordingly — with a week of preparation, assessors expect genuine research, and the Q&A goes deeper.

On-the-day short prep. The most common format now. A brief and a pack handed over with 15 minutes to 45 minutes to prepare, no internet, sometimes no slides — just paper and a pen. Tests thinking under time pressure far more than presentation craft.

Case-based. Built on the same case pack used for the written or group exercise, which means the assessors already know the material intimately and the questions will be precise.

Group presentation. The output of a group exercise, delivered by 2 or more candidates. Scored individually, which makes the handover between speakers unexpectedly important — a clean handover is an indicator, and a scramble is a visible one too.

Presentation to a single assessor. Common in remote centres. Harder than a panel, because there is almost no audience feedback to read.

Slot length runs 5 minutes to 15 minutes in the overwhelming majority of cases, followed by 5 minutes to 10 minutes of questions.

A fully worked example: the brief, the outline, and what fills it

Here is a realistic on-the-day brief, then the outline a strong candidate would produce inside 30 minutes of preparation. The outline is filled in with actual content, because an outline of placeholders is where most candidates stop and is exactly the gap that costs them.

PRESENTATION BRIEF

Preparation time: 30 minutes. Delivery: 10 minutes, followed by 5 minutes of questions. Flip chart available. No internet access.

Meridian Logistics operates a regional parcel network. Its overnight sorting hub in Coventry is running at 96 percent of capacity and has missed its next-day delivery commitment on 7 percent of parcels in each of the last 2 quarters, against a contractual threshold of 3 percent. Penalty payments to 2 major clients totalled £460,000 last year.

Three options have been put to the operations director:

A. Build a second hub in the North West. Capital cost £14 million, operational from month 20, reduces Coventry throughput by an estimated 35 percent. B. Add a third shift at Coventry. £2.1 million a year in staffing, available within 8 weeks, adds an estimated 18 percent effective capacity. C. Divert 20 percent of volume to a third-party carrier under a 3 year contract. £3.4 million a year, live within 6 weeks, but hands client relationships to a competitor for those parcels.

Your task: Recommend one option to the operations director. You may propose a combination.

And here is the outline. Not a shape — the actual content.

SLIDE / SECTION 1 — RECOMMENDATION (60 seconds)

"My recommendation is option B, the third shift at Coventry, started immediately — and I would use the 18 months it buys to complete the business case for the second hub rather than committing to £14 million today. Three reasons: the penalty problem is live now and only B fixes it inside 8 weeks; B is the cheapest of the 3 at £2.1 million a year; and it is the only option that doesn't foreclose a decision we don't yet have enough information to make."

SECTION 2 — WHY SPEED IS THE BINDING CONSTRAINT (2 minutes)

"We're missing the threshold at 7 percent against a contractual 3 percent, and we've done it 2 quarters running. That's £460,000 of penalties last year, but the larger exposure is contractual — 2 consecutive quarters of breach is usually the point at which clients start reviewing. Option A doesn't produce a single parcel of relief until month 20, which is 5 more quarters of breach. Whatever we do long term, we cannot do nothing for 20 months."

SECTION 3 — WHY B OVER C (2 minutes 30 seconds)

"Both B and C are fast — 8 weeks versus 6 weeks, which is close enough not to decide it. Three things separate them. Cost: £2.1 million against £3.4 million, so B is £1.3 million a year cheaper. Capacity: B adds an estimated 18 percent effective capacity against C's 20 percent diversion, which is roughly comparable against a 7 percent miss rate — both clear the gap. And the third is the one I'd weight most heavily: C puts a competitor in front of 20 percent of our clients' parcels for 3 years. If service quality on those parcels is good, we've demonstrated we're replaceable. If it's bad, we own the complaint and they own the relationship."

SECTION 4 — THE COUNTER-ARGUMENT (1 minute 30 seconds)

"The strongest case against me is capacity headroom. We're at 96 percent, B adds an estimated 18 percent, so we'd be running at roughly 81 percent of the new capacity — comfortable, but not if volume is growing. If the network is growing at more than 10 percent a year, B buys perhaps 2 years and we will have spent £4 million on shift costs before we start the hub anyway. So I'd make the recommendation conditional: approve the third shift now, and commission a 90 day demand forecast. If growth exceeds 10 percent, start the hub business case immediately rather than in 18 months."

SECTION 5 — CLOSE AND ASK (60 seconds)

"So: option B now for speed and cost, a 90 day forecast to size the hub decision properly, and a review point at 6 months. What I'd need from you is sign-off on the shift budget this month — every week we wait is another week at 7 percent."

That is roughly 8 minutes of speaking, leaving margin inside a 10 minute slot. Four things it does that most candidate presentations do not:

It answers first. The recommendation is in the opening 20 seconds. Assessors listening to 8 candidates in a day can tell within the first sentence whether someone has a structure, and the answer-first opening is the single clearest signal available. Candidates who build to a conclusion at minute 9 are asking a tired panel to hold context they may not hold.

It uses the brief's own numbers. Every claim is traceable: 96 percent, 7 percent, £460,000, month 20, 8 weeks. A presentation that says "option A is too slow" scores lower than one that says "option A produces no relief until month 20, which is 5 more quarters of breach," and the effort difference is close to zero.

It names its own weakest point before anyone else does. Section 4 is not padding. Voluntarily surfacing the strongest counter-argument is one of the most reliably high-scoring moves available, because it demonstrates that the candidate stress-tested their own position — and it defuses the question the assessors were about to ask.

It ends with an ask. "Sign-off on the shift budget this month" turns a talk into a recommendation. Presentations that trail off into "so those are my thoughts, happy to take questions" waste the strongest position in the whole structure.

A worked Q&A exchange

The questions are frequently where the exercise is won or lost, and they are scored — often on the same weighting as the delivery. Here is a realistic exchange on the presentation above.

Assessor: "You've recommended a £2.1 million annual cost to avoid £460,000 of penalties. That's a poor trade on the numbers. Why should I approve it?"

Candidate: "That's the right challenge, and on penalties alone you shouldn't. But the £460,000 is the smallest part of the exposure. Two things sit behind it. First, the contractual position: we've breached for 2 consecutive quarters, and the risk isn't the penalty, it's a client choosing not to renew — those 2 clients between them are worth considerably more than £2.1 million a year, or they wouldn't have penalty clauses that size. Second, at 96 percent of capacity we have no resilience. One depot outage or one peak week and the 7 percent becomes much worse. So I'd frame the £2.1 million as insurance against client loss and volume shock, not as a payment against a £460,000 penalty. If you told me those 2 contracts were worth less than £3 million a year combined, I'd change my recommendation to option C and take the relationship risk."

Look at what happens in that answer. The candidate concedes the valid part of the challenge immediately, which costs nothing and buys credibility. They reframe the metric being used — from penalty avoidance to contract retention — which is the substantive move. They name the piece of information they do not have. And in the last sentence they state, precisely, the condition under which they would change their mind.

That last sentence is worth isolating, because it is the single highest-scoring sentence type in any assessment centre Q&A: "If X were true, I'd recommend Y instead." It demonstrates that the position is reasoned rather than defended, which is exactly the distinction between the 2 middle scoring bands on most frameworks.

The failure modes on the same question are worth naming. Restating the presentation more loudly scores nothing. Capitulating entirely — "you're right, maybe option C" — scores worse than defending badly, because it shows the recommendation was never reasoned. Answering a different, easier question is usually noticed, and is recorded.

How to approach the prep window

Spend the first 5 minutes reading, not writing. With 30 minutes of preparation, roughly 5 minutes reading, 10 minutes deciding and structuring, 10 minutes filling in content, and 5 minutes rehearsing the opening and close out loud is a workable split. The instinct to start writing at minute 1 produces a presentation shaped like the pack rather than like an argument.

Decide your recommendation fast and stop revisiting it. Any defensible option, argued well, outscores the optimal option argued loosely. Candidates who spend 20 minutes agonising between B and C arrive with 10 minutes of content and no structure.

Write the first sentence and the last sentence in full. Everything in between can be notes. Openings and closes are where nerves are highest and where scripting helps most.

Time it once, out loud. Silent reading runs 30 percent to 40 percent faster than speaking. A candidate who has never spoken their content aloud has no idea how long it is.

Prepare 3 questions you hope they don't ask. Then answer them. This is 5 minutes of work and it converts the most dangerous part of the exercise into the most predictable.

How it varies by level and sector

Graduate schemes often use a general or research-based topic rather than a business case, sometimes prepared in advance. The bar is structure and clarity, not commercial depth.

Consulting and finance use case-based presentations with real numbers, short prep, and adversarial Q&A. Expect the questions to attack the arithmetic.

Public sector presentations tend to concern a policy or service question with multiple stakeholder interests, and are scored explicitly against named behaviours. Naming affected groups and trade-offs matters more than commercial optimisation.

Senior and executive presentations are often to a panel including prospective peers, on a genuine current problem in the business, with 60 minutes or more of preparation and questions that are effectively a working conversation.

Sales and commercial roles frequently present to a role-played customer rather than a panel, which merges this exercise with the role-play format.

Common mistakes

Too much content. First, largest, and covered above.

Building to the conclusion. Detective-story structure — evidence, evidence, evidence, reveal — is the natural way to write and the wrong way to present to assessors.

Reading slides aloud. If slides exist, they hold evidence, not sentences. A candidate reading a slide is not demonstrating verbal communication, and assessors mark that literally.

No counter-argument. A presentation with no acknowledged weakness reads as either naive or evasive, and hands the panel an easy first question.

Treating Q&A as an attack. It is a scored section, usually deliberately challenging, and often the assessors probing hardest are probing the candidates they rate highest.

Running over. Assessors will frequently stop you at the limit mid-sentence. It is scored, and it is entirely avoidable.

Apologising. "Sorry, I didn't have much time" at the start costs credibility and gains nothing — everyone had the same 30 minutes.

How to prepare

1. Practise the answer-first opening 10 times on 10 different topics. Recommendation, then 3 reasons, in under 60 seconds. It is a learnable reflex.
2. Do 3 timed runs at the real slot length. Aim to finish at 80 percent of the time allowed.
3. Record yourself once. Unpleasant, effective. Watch for filler, pace, and whether your structure is audible.
4. Build a reusable skeleton. Recommendation → binding constraint → comparison of the 2 serious options → counter-argument and condition → ask. It fits almost any business case brief you will be handed.
5. Practise the "if X, then Y instead" sentence until it comes out naturally under challenge.
6. Rehearse losing your place and recovering. The skill is not fluency, it is resumption — and a candidate who pauses, checks their notes and continues cleanly loses almost nothing on the sheet.
