The graduate program assessment centre season is officially underway.

Congratulations if you’ve made it this far. You're now just one step away from getting an offer, and hopefully this guide will help you get there.

Let’s start with a fun fact for no reason at all…

Did you know the concept of assessment centres started during World War II to identify military officers? The military used group exercises, intelligence tests, and leaderless discussions to identify who could actually lead under pressure.

Decades later, every major graduate employer still uses them. The reason is simple: they're among the strongest predictors of future job performance available to employers.

More predictive than interviews. More predictive than academic grades. More predictive than many of the selection methods candidates spend most of their time preparing for.

Before we get more into that, I have to share an exciting update with you.

What are graduate programs assessing you on?

Every assessment centre is different, and every employer has their own competency framework.

But across almost every centre you'll encounter in Australia, assessors are scoring five things consistently:

  • Communication

  • Teamwork

  • Problem-solving

  • Leadership potential

  • Decision-making

Here's the insight most candidates don't have going in: 

Assessors are watching your behaviour just as much, if not more, than they're evaluating your answer.

One of the biggest surprises for candidates is discovering that leadership isn't necessarily about having the best idea in the room. You can arrive at the wrong recommendation in a case study and still perform well. You can arrive at the correct recommendation and still fail.

Because the real question assessors are asking isn't whether you solved the problem. It's how you behaved while you were solving it. 

Did you listen? Did you build on other people's ideas? Did you help move the discussion forward when it stalled? Did you stay composed when things became unclear?

That's what gets scored. Not the answer, but the behaviour behind the answer.

The cultural bias problem no-one talks about

I’ve got some bad news for you.

Research consistently shows that ethnic minority candidates often underperform at assessment centres relative to their actual ability, and it's not because they're less capable. It's because many of the behaviours being rewarded in these settings are culturally specific.

A 2022 study published in BJGP Open found that first-generation ethnic minority GP trainees had odds of underperformance more than five times higher than their majority peers in standardised assessments, and similar findings have been reported across the UK, the US, and Australia.

In a typical Australian assessment centre, the behaviours that tend to get rewarded include:

  • Speaking up early

  • Volunteering opinions without being asked

  • Challenging ideas respectfully

  • Filling silence

  • Expressing confidence under uncertainty

For many Australian candidates, these behaviours feel completely normal. But for candidates from other cultural backgrounds, they can feel uncomfortable, overly aggressive, or even disrespectful to display, which creates a real problem.

It's not because assessors are intentionally biased, but because candidates are being evaluated in an environment that quietly rewards certain communication styles over others.

I won’t let this make me feel defeated. This is something you can prepare for, and that’s exactly what I want to cover in the rest of the newsletter.

Breaking down the exercises

Most Australian graduate assessment centres run for half a day and include some combination of the exercises below, though not every employer uses all of them.

The most common combination is a group exercise, a competency-based interview, and a case study or presentation.

Before you walk in, you need to actually know what the day will cover. Go through your invite properly, and if anything is unclear, don't hesitate to reach out to the recruiter and ask. Knowing exactly what the day looks like ahead of time is half the battle.

1. The group exercise

This is probably the exercise candidates worry about the most.

Typically, you'll be placed in a group of five or six candidates and given a business problem to solve, with around 30 to 45 minutes to work through it while assessors sit quietly in the room making notes.

They are not watching whether your group reaches the right answer. They are watching individual behaviours the entire time.

Dr. Dave Bartram, former Chief Psychologist at SHL, described the leaderless group discussion as "the single most revealing window into how someone actually operates in a team dynamic," adding that it is "very difficult to fake for 45 minutes."

The play that makes you memorable

Whenever a group exercise opens, there's always a few seconds of silence where everyone hesitates, and that moment is your opportunity.

You don't need to have the answer, and you don't need to be the smartest person in the room. But early movers always have an advantage. Breaking that silence when everyone's hesitating and going first will make you stand out.

Simply suggesting a structure is often enough: "Why don't we spend five minutes identifying the key issues before discussing recommendations?" You've immediately helped the group move forward, and that's exactly the type of behaviour assessors notice.

Throughout the discussion, focus on building rather than competing. Ask follow up questions, acknowledge good points, and connect ideas together. This way, you come across as collaborative and as someone with leadership qualities, while also making everyone else feel valued, which is the exact combination assessors are scoring for.

What tends to get candidates cut is dominating the conversation, going silent for long stretches, shooting down others' ideas, or only speaking when they're completely certain they're right.

2. The case study and written exercise

This exercise usually involves a business scenario. You'll receive data, charts, competing priorities, and limited time, then you'll be asked to analyse it and present your findings either verbally or in writing.

Most candidates build up to their answer like they're constructing a suspense novel, slowly working through every detail before finally arriving at a conclusion. The strongest candidates do the opposite. They start by creating structure rather than getting lost in the detail.

The play that makes you memorable

One of the most useful habits you can build is recommendation-first thinking. Instead of slowly building toward your conclusion, start with it: "My recommendation is X, for three reasons," and then explain your reasoning from there.

This is also exactly how executives communicate, and it's the same principle management consultants are trained on from day one.

When you walk into a meeting with a senior leader, you don't get the luxury of building suspense. You lead with the answer, because their attention span for getting there is short and their need for clarity is high.

Assessors have effectively sat through a junior version of that exact meeting hundreds of times, which is why clarity gives you such a competitive advantage in this exercise.

A clear recommendation supported by logic is usually far more persuasive than a perfect answer buried inside a confusing explanation, and it signals to assessors that you already think the way the business wants you to think.

3. The competency-based interview

This is the one-on-one interview, usually competency-based, meaning every question is trying to uncover evidence of a specific skill such as leadership, teamwork, communication, resilience, or problem-solving.

The STAR framework works well here: Situation, Task, Action, Result. One thing worth keeping in mind is that the challenge or task you describe needs to sound real and significant, because if the problem sounds small, your solution will never land as impressively as it should, no matter how well you execute it.

Prepare six to eight examples covering leadership, teamwork, problem-solving, communication, and resilience, but don't memorise them word for word. Know your stories, not your lines, so they come across naturally rather than rehearsed.

The play that makes you memorable

The single most common mistake international students make in this exercise is using "we" throughout their answer. I addressed this directly in a previous newsletter, but it's worth repeating here because it matters this much.

Assessors need to understand your individual contribution, not your team's. "We delivered the project" tells them nothing about you specifically.

"I coordinated the team's timelines and managed communication between stakeholders" tells them everything, and it's the difference between sounding like a participant and sounding like someone who actually drove the outcome.

4. The presentation

The presentation can be individual or in a group, and the topic can be pre-prepared in advance or handed to you on the day with very little time to prepare. You might be asked to present a recommendation, pitch an idea, or summarise findings from an earlier exercise like the case study.

Either way, you're standing in front of assessors, and sometimes other candidates, with everyone watching how you handle it.

Candidates are assessed on structure, delivery, commercial awareness where relevant, and composure during the Q&A that follows.

That last point matters more than people expect. A polished presentation can completely fall apart in the questions afterwards if you haven't thought beyond your slides, and assessors know this, which is exactly why they probe.

The play that makes you memorable

The strongest presentations don't open with an agenda slide. They open by establishing why this topic actually matters to the audience in front of them. Before you say what you're going to cover, say why anyone in the room should care.

Compare these two openings: "Today we will be talking about this topic," versus "Every year, organisations lose millions because they underestimate this topic, and that's exactly why this matters to all of us in this room." The second one does something the first one doesn't. It tells the audience why they should be listening before you've even given them anything to listen to.

Most candidates spend almost all of their preparation time on the content itself, the recommendations, the structure, the slides.

Far fewer spend time on the purpose, on the one sentence that justifies why this presentation deserves the room's attention in the first place. That's usually the gap between a presentation that's competent and one that's memorable.

5. The in-tray and e-tray exercise

This exercise is designed to feel overwhelming, and that's intentional. You'll receive emails, reports, requests, deadlines, and competing priorities all at once, with a fixed amount of time to work through them and respond.

It's meant to simulate the chaos of an actual workday, just compressed into a much shorter window so assessors can see how you cope with it.

This tests decision-making, prioritisation, and attention to detail, but what it's really testing is whether you can think clearly when everything feels urgent at once.

The play that makes you memorable

Resist the urge to dive straight in. Spend more time than feels comfortable building your prioritisation logic before you touch a single response. Instead of starting with the first email in the pile, spend the first two to three minutes reading everything and sorting it into buckets, but the bucket labels matter less than having a clear, consistent rule for how you're sorting.

For example, your logic might be: anything involving a client or external stakeholder gets actioned first, because reputational risk is hardest to undo. Then anything with a same-day deadline. Then internal requests that can wait until tomorrow without real consequence. Or your logic might be entirely different, ranking by financial impact, or by who is most senior, or by what blocks other people's work versus what only blocks your own.

It matters less which logic you pick, and more that you have one. What matters is that you can articulate it clearly if asked, and that you apply it consistently across every item in the pile.

Assessors are watching whether you have a system, not just whether you eventually got to everything. The candidates who dive in headfirst usually end up spending the most time and effort on the least important task in the pile, simply because it happened to be first.

6. The role play

This is often the most uncomfortable exercise of the entire day. You'll usually be placed opposite an assessor playing a difficult client, colleague, or stakeholder, and given a scenario where something has gone wrong or someone is unhappy.

Assessors are watching your communication, empathy, composure, and whether you can actually navigate a difficult conversation toward some kind of resolution, rather than just surviving it.

When tension increases, most candidates instinctively speed up. They rush to solve the problem, jumping straight to a fix because the silence and discomfort feel unbearable.

The play that makes you memorable

Do the opposite. When someone raises a concern, acknowledge it first, then respond. Something as simple as "That's a valid concern, let me think about that for a moment" does two things at once.

It makes the other person feel genuinely heard, and it buys you a few seconds to actually think instead of blurting out the first thing that comes to mind.

In difficult conversations, that pause is often your biggest advantage. Slowing down doesn't read as uncertainty to an assessor. It reads as composure, and composure under pressure is exactly what this exercise exists to test.

The how: your preparation plan

Knowing what is being assessed is only useful if you prepare specifically for it. Here's how.

Research the competency framework before you arrive. Every major employer publishes the competencies they assess against on their careers website. Read it. 

Every exercise in the assessment centre is designed around those competencies. If "collaboration" is on the list, every exercise, the group discussion, the case study, the interview, is an opportunity to demonstrate collaboration. Align your preparation to their language.

Practice out loud. Reading about STAR answers is not the same as saying one out loud. Time yourself. Record yourself. The first time you deliver a structured answer under pressure should not be in the assessment centre room.

Prepare your six to eight stories now, before you know which exercises are coming. Competency-based questions can surface in any exercise. Having your examples ready means you're drawing from a prepared repertoire rather than constructing answers under pressure.

Use these resources:

No matter how much you prepare, you're going to be nervous on the day. That's completely natural, and honestly, it's a good sign. It means you care about the outcome.

What's worth remembering is that pressure reveals behaviour, and the candidates who perform best at assessment centres aren't always the most talented in the room. They're usually the ones who understood exactly what was being assessed and prepared specifically for it, rather than just hoping their natural ability would carry them through.

You now know what they're looking for. The rest is just preparation.
