Why Hiring Problems Often Start Long Before Performance Is Measured

Most organisations believe their hiring problems begin when someone underperforms. They point to the six-month review, the missed targets, and the team friction. But the truth is far more uncomfortable: the problem started weeks earlier, in the hiring process itself.

By the time performance issues surface, you’ve already invested thousands in recruitment, onboarding, and training. The cost isn’t just financial; it’s cultural, operational, and strategic. And yet, most HR leaders continue to measure success at the wrong point in the journey.

The question isn’t whether your new hire can do the job. It’s whether you understood them well enough to place them in it.

The Real Cost of Traditional Hiring

Traditional hiring relies heavily on CVs, interviews, and references. These tools provide snapshots of experience and capability, but they reveal little about behaviour, adaptability, potential or cultural fit. The result? Decisions made on incomplete information.

Consider this: a candidate with an impressive track record in a fast-paced, deadline-driven environment accepts a role in a collaborative, process-oriented team. On paper, they’re perfect. In practice, they’re struggling within weeks. Not because they lack skill, but because no one assessed whether their behavioural and personality characteristics aligned with the demands of the role and the culture of the team.

The weakness isn’t in their resume. It’s in your process.

Where Hiring Decisions Go Wrong

Every people metric—engagement, culture, performance, retention—is ultimately shaped by four fundamental people science factors. Rooted in organisational psychology, psychometrics, and behavioural science, these domains form the foundation of Thomas International’s scientifically validated assessment framework:

1. Behaviour Patterns (measured through Thomas Behaviour): How people naturally approach tasks, interact with others, and respond to their environment. These patterns influence everything from handling pressure to collaborating under tight deadlines.

2. Personality Traits (assessed via Thomas Personality): The underlying traits that shape how people see the world and make decisions. Research in organisational psychology consistently shows that personality-role fit predicts both performance and retention, determining motivation and long-term sustainability in a role.

3. Emotional Intelligence (evaluated using Thomas Emotional Intelligence): The capacity to recognise, understand, and manage emotions. Studies on emotional intelligence in leadership demonstrate that EQ often matters more than IQ in management effectiveness, particularly in complex interpersonal dynamics

4. Cognitive Ability (tested through Thomas Aptitude): How quickly someone learns, solves problems, and adapts to change. Understanding learning capacity helps organisations set realistic expectations and place people where they can genuinely succeed.

Why Capability Must Come Before Diagnostics

1. Assessing Hard Skills, Ignoring Soft Skills

Most hiring processes focus on competencies: Can they code? Can they manage? Can they sell? These are important questions, but they’re not predictive of success as cited by SHRM Labs, whereby 46% of new hires fail within their first 18 months due to behavioural misfits. Behavioural tendencies, how someone communicates under pressure, approaches problem-solving, or responds to feedback, are far better indicators of performance and retention.

2. Prioritising Culture Fit Without Defining It

Culture fit is one of the most misused terms in hiring. Without a clear understanding of your organisational culture and the behavioural traits that support it, culture fit becomes subjective, biased, and ultimately unhelpful. You end up hiring people who feel right rather than the right people.

3. Relying on Gut Feel in Final Decisions

Even when structured processes are in place, final hiring decisions often come down to intuition. Hiring managers default to what feels comfortable, reinforcing existing biases and overlooking candidates who might bring valuable diversity of thought and approach. Gut feel has its place, but it shouldn’t be the deciding factor in a six-figure investment.

What People Science Reveals About Early Hiring

People science offers a different approach. It doesn’t replace CVs or interviews; it enhances them by adding behavioural clarity to every hiring decision. According to a Cambridge-published article, structured behavioural interviews are top predictors of job performance, outperforming unstructured interviews and years of experience.

Through validated psychometric profiling, you gain insight into how a candidate is likely to behave in role-specific situations: how they handle autonomy, respond to structure, engage with teams, and navigate change. This isn’t about personality typing or labelling, it’s about understanding the behaviours that drive performance and using that understanding to make better placement decisions.

For example:

A candidate who thrives on variety and fast decision-making may excel in a dynamic, high-growth environment but struggle in a compliance-heavy, risk-averse one.

A naturally collaborative individual might find individual contributor roles isolating, even if they have the technical skills to succeed.

Someone who values structure and process may clash with a team that operates on flexibility and iteration.

None of these scenarios reflects a lack of capability. They reflect a lack of alignment, and alignment is what people science helps you achieve.

The Shift: From Reactive Measurement to Proactive Decision-Making

Traditional hiring is reactive. You make a decision, wait for performance data, and course-correct when things go wrong. By then, the damage is done, and the wrong hire has already cost you time, money, and team morale.

People science enables proactive decision-making. It allows you to understand fit before the offer is made, predict behavioural alignment before someone starts, and reduce the risk of misalignment before it becomes a performance issue.

This doesn’t eliminate hiring risk; nothing does. But it significantly reduces it, and it does so at the stage where intervention is most valuable: before the decision is made.

Why This Matters Now

Talent markets are competitive. Hiring costs are rising. Time-to-productivity expectations are tightening. In this environment, poor hiring decisions are more expensive than ever, and the margin for error is narrower.

Organisations that continue to rely on traditional hiring methods will continue to experience the same problems: high early-stage attrition, extended time-to-performance, and persistent misalignment between people and roles.

The alternative is to recognise that hiring problems don’t start when someone underperforms. They start when you fail to understand them in the first place.

Moving Forward: What This Looks Like in Practice

Integrating people science into your hiring process doesn’t require overhauling your entire recruitment function. It requires three simple shifts:

1. Assess behaviour alongside competence: Use validated behavioural profiling to understand how candidates approach work, not just what they’ve accomplished.

2. Define role and culture requirements behaviourally: Before you hire, be clear on the behavioural traits that drive success in the role and fit within your team. Vague notions of culture fit won’t cut it.

3. Use data to inform, not replace, decision-making: People science provides clarity, not certainty. Use it to reduce risk and increase confidence, but don’t treat it as a substitute for human judgment.

Real-World Application: How Valiram Redefined Retail Hiring Across Southeast Asia

Theory is valuable. The application is transformative. Valiram, Southeast Asia’s leading luxury and lifestyle retailer, faced a challenge common to many organisations: traditional hiring methods were no longer producing consistent results.

Operating across the Asia Pacific markets with vastly different economic and educational landscapes, Valiram needed a way to identify high-potential retail staff that went beyond CV reviews and standard interviews. As Daniel Webb, Head of People Strategy Partnering at Valiram Group, noted: “We can’t rely on past performance or resumes. In many cases, people haven’t gone to university or even completed formal education.”

The Approach

Valiram partnered with Thomas to conduct a deep analysis of employee performance across four distinct brand categories. Using behavioural profiling, aptitude testing, and personality assessments, they compared consistent high achievers against underperformers in each market and brand.

The results were striking. High performance looked different across brands and markets. In the luxury watch division, success required methodical relationship-building and long-term client cultivation. In Bath & Body Works, high performers were fast, responsive, and energetic. The behavioural profiles were completely different, and both were right for their context.

Market differences were equally revealing. In Malaysia and Indonesia, where formal higher education is less common, traits like curiosity and initiative distinguished top performers. In Singapore, emotional intelligence and strategic relationship-building were more closely linked to sales success.

The Impact

Armed with this data, Valiram redesigned their entire talent strategy:

Job descriptions were rewritten to reflect behavioural traits linked to high performance.

Interviews were redesigned to include behavioural role-plays and store-based assessments that observed real behaviour.

Training programs were rebuilt around developing traits like curiosity, communication, and collaborative competitiveness.

Educational partnerships were established with universities to align curriculum with the behaviours that drive retail success.

The results were tangible. Group-wide attrition dropped from 37-38% to 31%. Early-stage attrition, employees leaving within the first six months, also decreased. Time-to-fill, time-to-competency, and internal promotion rates all improved. Of the 344 employees promoted in the latest cycle, the overwhelming majority demonstrated the behaviours Thomas had identified as linked to long-term success.

As Webb reflected: If the people we hire show these traits, and they’re getting promoted and staying longer, then we know we’re on the right track.

This wasn’t just a hiring intervention. It was a strategic reset, one that demonstrates what becomes possible when you understand people before you place them.

The Bottom Line

Hiring problems don’t begin when performance is measured. They begin when understanding is absent. If you’re waiting until someone underperforms to recognise a hiring mistake, you’re measuring the problem, not preventing it.

The weakness in early hiring decisions isn’t a lack of tools or processes. It’s a lack of behavioural insight. And behavioural insight is something you can, and should, build into your hiring process now.

Because the best time to address a hiring problem isn’t after. It’s before the offer is made.
