Let’s discuss the significant issues that talent acquisition teams face with assessment centres and talent assessment tools every day. As a solution provider operating in the high-volume recruiting space, we’ve identified seven common problems with assessment centres and the use of talent assessment tools.
Firstly, a bit of an explanation.
Assessment Centres or “Group Interviews” are a popular recruitment tool for those who specialise in high volume recruitment or large enrolment programs. They usually bring together a large number of candidates. This group is then reduced to a smaller group in the final phase of the recruiting selection process.
Firstly, group interviews offer significant advantages for high-volume recruitment. They are thought to yield better results. For every candidate interviewed more are hired with greater accuracy. That is, compared to standard face-to-face interviews. They are also quicker. In that, there is far greater efficiency in the number of candidates interviewed per hour. Many large-scale recruitment programs use assessment centres to evaluate candidates against one another using various exercises. These exercises are designed to assess your suitability for the job. They check your performance in your role as well as your knowledge of the company and its culture. Some exercises involve you working individually. Others assess you and your ability to work as part of a group.
For the candidate:
An invitation to an assessment centre shows that you are successful in the early stages of the recruitment process. It usually takes place after the first round of pre-selection interviews and before the final selection. This can be seen as more reliable and fair than an interview alone. It gives you the chance to demonstrate your potential in a variety of environments. Candidates should also be able to learn more about the culture of the organisation and the role of the workplace.

Assessment Centres provide an evaluation method based on multiple evaluations, including occupational simulations. They monitor a candidate’s performance across a range of activities. This is to assess skills, competencies and traits that could be used in the workplace. Many companies use this method to recruit their graduate programs. In other words, to assess potential employees who have little or no professional experience. The bonus is that it also gives employers the opportunity to make a positive impression.
1. They are a pain to organise.
“No Julie, we do not have an afternoon session on Tuesday just on Monday and Thursday” – sound familiar?
2. No one wants to be there.
The candidate wishes they had a job already. The hiring manager wishes they had their staff already. The recruiter wishes they were out for lunch. The general tone is: “when will this be over?”.
3. They are disappointing.
The results are never what you expected – for anyone! Maybe you attend with optimism. More likely you probably think to yourself “how will I select from this dire bunch of candidates???!“.
And every candidate is thinking: “This is ridiculous and unfair and like …totally ridiculous”.
4. Speaking loud seems to get you noticed.
Seems like whether you are the assessor or the candidate, the person who speaks loud often wins out. Almost always leaving participants to wonder: “Were fair decisions made and were the right decisions made?“.
Loud does not equate to right. Being confident does not equate to right either. Right?
5. They are all different.
There is little to no consistency or standardisation. For anyone is part of a national or global talent acquisition team – this is somewhat worrying. Particularly when you are recruiting for the same role across multiple geographies. When the bar to enter that role (and your organisation) moves, its a shift in goalposts and everyone knows: “that just ain’t fair!”.
6. Keeping the paperwork for compliance reasons is terribly time-consuming.
The record-keeping on assessment centres is an administrators nightmare. The spreadsheets to obtain attendance records, then print-outs to capture scoring. And for how long do you actually have to keep every scoring sheet? Is it a year or is it 7?
7. Calibration is rarely objective and never data-driven.
In concluding the assessment centre, the team calibrate their results together. This is the final decision-making process. Who should we progress to hire and who should be declined?
For anyone who has been an assessor, we all know that this calibration piece is too often based on opinions: “I believe she will really fit in” “She seemed to be super friendly” “I think she will be a great hire”. Believe, seemed, think. What is this? A fortune-tellers table in the corner of a dodgy country market? What happened to objective decision making?

Above all, they are ridiculously time-consuming! With so much time being spent on Group Interviews, should we think seriously about how they could be done better? Hours organising and days invested in an event with unpredictable results. Seems crazy! Can we do something to improve this costly and unwieldy process?
It is for these reasons that Sapia has launched LiveInterview – the app that specialises in making group interviews:
1. Easier to organise
2. A pleasure to be there
3. Yield better results – especially considering all attendees were preselected using FirstInterview!
4. Totally fair and equitable
5. Consistent and standardised
6. Easy to administer. No record-keeping needed anymore, ever
7. Data-driven objective decision making plus it delivers a better hiring yield.
Now, let’s make the assessment centre shine, and produce the results we expect. To learn more, leave your details here, and we will be in contact.

Why neuroinclusion can’t be a retrofit and how Sapia.ai is building a better experience for every candidate.
In the past, if you were neurodivergent and applying for a job, you were often asked to disclose your diagnosis to get a basic accommodation – extra time on a test, maybe the option to skip a task. That disclosure often came with risk: of judgment, of stigma, or just being seen as different.
This wasn’t inclusion. It was bureaucracy. And it made neurodiverse candidates carry the burden of fitting in.
We’ve come a long way, but we’re not there yet.
Over the last two decades, hiring practices have slowly moved away from reactive accommodations toward proactive, human-centric design. Leading employers began experimenting with:
But even these advances have often been limited in scope, applied to special hiring programs or specific roles. Neurodiverse talent still encounters systems built for neurotypical profiles, with limited flexibility and a heavy dose of social performance pressure.
Hiring needs to look different.
Truly inclusive hiring doesn’t rely on diagnosis or disclosure. It doesn’t just give a select few special treatment. It’s about removing friction for everyone, especially those who’ve historically been excluded.
That’s why Sapia.ai was built with universal design principles from day one.
Here’s what that looks like in practice:
It’s not a workaround. It’s a rework.
We tend to assume that social or “casual” interview formats make people comfortable. But for many neurodiverse individuals, icebreakers, group exercises, and informal chats are the problem, not the solution.
When we asked 6,000 neurodiverse candidates about their experience using Sapia.ai’s chat-based interview, they told us:
“It felt very 1:1 and trustworthy… I had time to fully think about my answers.”
“It was less anxiety-inducing than video interviews.”
“I like that all applicants get initial interviews which ensures an unbiased and fair way to weigh-up candidates.”
Some AI systems claim to infer skills or fit from resumes or behavioural data. But if the training data is biased or the experience itself is exclusionary, you’re just replicating the same inequity with more speed and scale.
Inclusion means seeing people for who they are, not who they resemble in your data set.
At Sapia.ai, every interaction is transparent, explainable, and scientifically validated. We use structured, fair assessments that work for all brains, not just neurotypical ones.
Neurodiversity is rising in both awareness and representation. However, inclusion won’t scale unless the systems behind hiring change as well.
That’s why we built a platform that:
Sapia.ai is already powering inclusive, structured, and scalable hiring for global employers like BT Group, Costa Coffee and Concentrix. Want to see how your hiring process can be more inclusive for neurodivergent individuals? Let’s chat.
There’s growing interest in AI-driven tools that infer skills from CVs, LinkedIn profiles, and other passive data sources. These systems claim to map someone’s capability based on the words they use, the jobs they’ve held, and patterns derived from millions of similar profiles. In theory, it’s efficient. But when inference becomes the primary basis for hiring or promotion, we need to scrutinise what’s actually being measured and what’s not.
Let’s be clear: the technology isn’t the problem. Modern inference engines use advanced natural language processing, embeddings, and knowledge graphs. The science behind them is genuinely impressive. And when they’re used alongside richer sources of data, such as internal project contributions, validated assessments, or behavioural evidence, they can offer valuable insight for workforce planning and development.
But we need to separate the two ideas:
The risk lies in conflating the two.
CVs and LinkedIn profiles are riddled with bias, inconsistency, and omission. They’re self-authored, unverified, and often written strategically – for example, to enhance certain experiences or downplay others in response to a job ad.
And different groups represent themselves in different ways. Ahuja (2024) showed, for example, that male MBA graduates in India tend to self-promote more than their female peers. Something as simple as a longer LinkedIn ‘About’ section becomes a proxy for perceived competence.
Job titles are vague. Skill descriptions vary. Proficiency is rarely signposted. Even where systems draw on internal performance data, the quality is often questionable. Ratings tend to cluster (remember the year everyone got a ‘3’ at your org?) and can often reflect manager bias or company culture more than actual output.
The most advanced skill inference platforms use layered data: open web sources like job ads and bios, public databases like O*NET and ESCO, internal frameworks, even anonymised behavioural signals from platform users. This breadth gives a more complete picture, and the models powering it are undeniably sophisticated.
But sophistication doesn’t equal accuracy.
These systems rely heavily on proxies and correlations, rather than observed behaviour. They estimate presence, not proficiency. And when used in high-stakes decisions, that distinction matters.
In many inference systems, it’s hard to trace where a skill came from. Was it picked up from a keyword? Assumed from a job title? Correlated with others in similar roles? The logic is rarely visible, and that’s a problem, especially when decisions based on these inferences affect access to jobs, development, or promotion.
Inferred skills suggest someone might have a capability. But hiring isn’t about possibility. It’s about evidence of capability. Saying you’ve led a team isn’t the same as doing it well. Collecting or observing actual examples of behaviour allows you to evaluate someone’s true competence at a claimed skill.
Some platforms try to infer proficiency, too, but this is still inference, not measurement. No matter how smart the model, it’s still drawing conclusions from indirect data.
By contrast, validated assessments like structured interviews, simulations, and psychometric tools are designed to measure. They observe behaviour against defined criteria, use consistent scoring frameworks (like Behaviourally Anchored Rating Scales, or BARS), and provide a transparent, defensible basis for decision-making. In doing this, the level or proficiency of a skill can be placed on a properly calibrated scale.
But here’s the thing: we don’t have to choose one over the other.
The real opportunity lies in combining the rigour of measurement with the scalability of inference.
Start with measurement
Define the skills that matter. Use structured tools to capture behavioural evidence. Set a clear standard for what good looks like. For example, define Behaviourally Anchored Rating Scales (BARS) when assessing interviews for skills. Using a framework like Sapia.ai’s Competency Framework is critical for defining what you want to measure.
Layer in inference
Apply AI to scale scoring, add contextual nuance, and detect deeper patterns that human assessors might miss, especially when reviewing large volumes of data.
Anchor the whole system in transparency and validation
Ensure people understand how inferences are made by providing clear explanations. Continuously test for fairness. Keep human oversight in the loop, especially where the stakes are high. More information on ensuring AI systems are transparent can be found in this paper.
This hybrid model respects the strengths and limits of both approaches. It recognises that AI can’t replace human judgement, but it can enhance it. That inference can extend reach, but only measurement can give you higher confidence in the results.
Inference can support and guide, but only measurement can prove. And when people’s futures are on the line, proof should always win.

Hiring for care is unlike any other sector. Recruiters are looking for people who can bring empathy, resilience, and energy to the most demanding human roles. Whether it’s dental care, mental health, or aged care, new hires are charged with looking after others when they’re most vulnerable. The stakes are high.
Hiring for care is exactly where leveraging ethical AI can make the biggest impact.
The best carers don’t always have the best CVs.
That’s why our chat-based AI interview doesn’t screen for qualifications. It screens for the the skills that matter when caring for others. The traits that define a brilliant care worker, things like:
Empathy, Self-awareness, Accountability, Teamwork, and Energy.
The best way to uncover these traits is through structured behavioural science, delivered through an experience that allows candidates to open up. Giving candidates space to give real-life, open-text answers. With no time pressure or video stress. Then, our AI picks up the signals that matter, free from any demographic data or bias-inducing signals.
Candidates’ answers to our structured interview questions aren’t simply ticking boxes. They’re a window into how someone shows up under pressure. And they’re helping leading care organisations hire people who belong in care and those who stay.
Inclusivity should be a core foundation of any talent assessment, and it’s a fundamental requirement for hirers in the care industry.
When healthcare hirers use chat-based AI interviews, designed to be inclusive for all groups, candidates complete their interviews when and where they choose, without the bias traps of face-to-face or phone screening. There are no accents to judge, no assumptions, just their words and their story.
And it works:
Drop-offs are reduced, and engagement & employer brand advocacy go up. Building a brand that candidates want to work for includes providing a hiring experience that candidates want to complete.
Our smart chat already works for some of the most respected names in healthcare and community services. Here’s a sample of the outcomes that are possible by leveraging ethical AI, a validated scientific assessment, wrapped in an experience that candidates love:
The case study tells the full story of how Sapia.ai helped Anglicare, Abano Healthcare, and Berry Street transform their hiring processes by scaling up, reducing burnout, and hiring with heart.
