Most organisations don’t fail because of poor strategy.

They fail because the wrong people end up in the wrong roles especially leadership roles.

And nowhere is this more evident or more costly than in senior hiring.

Over the past 25 years working in psychometric assessment across four countries, I’ve sat in countless post-mortems after senior hires went wrong usually 6 to 12 months after appointment, when the cost was already significant.

The pattern is remarkably consistent. The candidate interviewed well. The CV was b. References were positive. But over time the cracks appeared execution slowed, teams disengaged, momentum was lost.

On paper, the hire looked exceptional. Within nine months, execution had slowed, key staff had exited, and the leadership team had quietly lost confidence.

The Real Cost of Getting It Wrong

Research consistently estimates the cost of a failed senior hire at between one and three times annual salary once productivity loss, team disruption, client impact, performance management, and rehiring costs are considered.

But the financial cost is often not the biggest one. The deeper damage is cultural. Poor leadership appointments can quietly erode trust, destabilise teams, and drive out exactly the people organisations most need to retain.

The Process Hasn’t Kept Up With the Role

Most organisations still make hiring decisions using a process that hasn’t fundamentally changed in decades: CV-driven shortlisting, interview-led evaluation, and intuition-based final decisions.

Yet the roles themselves have changed dramatically. Modern leadership positions demand greater cognitive complexity, ber behavioural consistency under pressure, and the ability to lead, influence, and execute simultaneously.

The demands of the role have evolved. The way we assess people has not. That gap is precisely where hiring risk lives.

Why Smart Leaders Still Get This Wrong

The organisations making these mistakes are rarely careless. The problem isn’t intent — it’s method. Four failure modes appear consistently:

• Over-reliance on the interview. Interviews are fundamentally a performance. b candidates know how to present well, yet unstructured interviews have surprisingly low predictive validity for actual job performance.
• Hiring for competence while missing character. Most processes assess technical capability well but rarely surface the behavioural tendencies that determine how someone actually leads under pressure. Most senior hiring failures are not failures of capability. They are failures of judgement, temperament, resilience, alignment, and behaviour under pressure.
• Over-reliance on reference checks. Candidates select referees who are likely to speak positively. Positive references often create reassurance but rarely reveal how someone behaves when things become difficult.
• Treating all roles as equivalent risk. Not every appointment carries the same consequence. Yet many organisations apply the same level of scrutiny regardless of the role’s strategic impact. High-consequence roles require deeper, more risk-calibrated evaluation than lower-impact appointments.

What Better Actually Looks Like

Better hiring is not about adding more complexity or more data. It is about improving the quality of decision-making itself.

At its core, this means:

• Clearly defining what success in the role actually requires
• Assessing not just experience, but cognitive capability and behavioural patterns
• Identifying both strengths and potential risks
• Applying consistent, evidence-based evaluation criteria
• Aligning the depth of assessment to the actual risk of the role
• Moving beyond intuition toward structured, evidence-informed judgement

A Question Worth Sitting With

Think about the three or four most consequential appointments your organisation has made in the past three years. Could you confidently defend those decisions using objective, structured evidence not just instinct or a good feeling?

For many organisations, the honest answer is no. And that’s not a criticism it’s an opportunity.

In the end, most business problems eventually become people problems. And the quality of your people decisions will usually determine the quality of your business outcomes.

I’d love to hear your experience: what’s the most consequential hiring decision you’ve seen go wrong and in hindsight, what were the warning signs?
