Your Hiring Process Was Built to Find Talent. That's the Problem.
Most organisations are not failing to hire talented people. They are failing to predict how those people will function once the job begins. Here is the framework that is changing that and what founders need to understand before their next hire.
Here is a number worth sitting with: most employee turnover happens in the first 12 to 18 months. Not because people lacked skills or weren't talented enough. It's because something about the role, the environment, or the demands of the work turned out to be fundamentally misaligned with how that person actually operates.
By the time the turnover happens, the organisation has already absorbed the cost. Through lost productivity, the time spent managing underperformance, the disruption to the team, and the expense of rehiring. Most of that cost was baked in the moment the wrong hire was made.
The uncomfortable question is why this keeps happening when hiring has, by almost every measure, never been more sophisticated. Applicant tracking systems, structured interview frameworks, competency assessments, AI screening tools; organisations have invested heavily in improving how they hire. And yet the outcomes have not improved commensurately.
The explanation, according to a growing body of organisational psychology research, is that most hiring systems were built to optimise efficiency rather than accuracy. They are designed to process candidates faster, at higher volume, with more consistent surface-level evaluation. What they are not designed to do is predict how a person will actually function once the novelty of a new role wears off and the real pressures of the job begin.
Why Interviews, Resumes, and Culture Fit Keep Failing

Interviews are still treated as the gold standard of candidate evaluation in most organisations, despite substantial evidence that they are a poor predictor of long-term job performance. The problem is structural: interviews reward the skills needed to perform well in interviews, which are not necessarily the skills needed to perform well in the role.
Verbal fluency, social confidence, and the ability to construct a compelling narrative under time pressure are what interviews measure. A candidate who is reflective, analytical, and introverted will often underperform in an interview relative to their actual capabilities — because those traits require time and context to become visible, and interviews provide neither.
Resumes have a different limitation. They document exposure, not execution. A resume tells you where someone has been and what they have nominally done. It cannot tell you how they think, how they make decisions under pressure, whether they thrive in ambiguity or require structure, or how they recover when things go wrong. These factors are often more predictive of long-term success than technical experience — but they are invisible on a CV.
Culture fit is perhaps the most problematic of the three. It is one of the most commonly cited hiring criteria and one of the least defined. In practice, it tends to mean familiarity — shared communication styles, similar backgrounds, recognisable patterns of thinking and expression. It is, functionally, a mechanism for hiring people who are like the people who already work there. This limits diversity of thought, over-indexes on sameness, and has very little to do with whether the candidate can actually do the job.
The result is a systematic bias toward visibility rather than viability. The candidates who get hired are the ones who present well. The candidates who would actually sustain high performance over time are frequently lost in a process that was never designed to find them.
What the Research Says Actually Predicts Success
Decades of research in organisational psychology consistently identify three variables that outperform interviews, resumes, and intuition as predictors of long-term job performance.
The first is behavioural tendencies — the relatively stable patterns that govern how a person shows up at work. How they communicate, collaborate, manage stress, handle conflict, and take initiative. These are not the same as personality traits in the casual sense. They are observable, measurable patterns that remain consistent across contexts and over time. When a role aligns with these tendencies, performance feels sustainable. When it doesn't, friction accumulates quietly — often invisible to both the employee and their manager — until it becomes visible as disengagement, underperformance, or departure.
The second is cognitive processing style — how someone thinks, learns, and solves problems. Two candidates with identical experience can differ dramatically in how they process information, how fast they make decisions, how they handle ambiguity, and what kinds of problems they are naturally equipped to solve. One may excel in fast-moving, unstructured environments. The other may produce their best work in contexts that reward precision, depth, and methodical execution. Neither is more valuable than the other. They are suited to different roles, and placing them in the wrong one produces predictable underperformance that looks like a talent problem but is actually a fit problem.
