The most important moment in this executive search wasn't the interview. It wasn't the shortlist. It wasn't even the offer.

It was a conversation that happened after the client believed they had found their next Chief Operating Officer.

That conversation uncovered information that completely changed the outcome of the search.

The client was a private equity-backed residential services platform generating more than $150 million in revenue, with an ambitious long-term goal: To build one of the most professionalised businesses in its sector and scale towards $1 billion in revenue.

They weren't simply looking to fill a vacancy. They were making a leadership appointment that could have a significant influence on whether the business achieved that ambition.

What followed was a search that demonstrated why executive due diligence matters.

Part One: The Brief

When the CEO approached Raw Selection, the business needed a senior operational leader.

This wasn't the first time someone had occupied the position. A previous operational appointment hadn't worked out. The individual understood operations but lacked the depth of industry experience the business needed. More importantly, they had struggled to establish credibility with the technicians responsible for delivering the work every day.

That experience had helped clarify what the business needed this time.

As we worked through the brief with the client, it became apparent that they weren't describing a Vice President of Operations or a traditional Head of Operations. They needed a true Chief Operating Officer: someone capable of leading a large multi-site platform, integrating acquisitions, building operational systems and earning the trust of people at every level of the organisation, from technicians in the field to private equity stakeholders in the boardroom.

The ideal candidate therefore required a particularly difficult combination of experience. They needed significant P&L responsibility, experience leading across multiple branches, a servant leadership approach and, crucially, a background in residential HVAC that would allow them to speak the same language as the people operating within the businesses.

That conversation became the blueprint for everything that followed.

Part Two: The Hunt

Once the mandate had been established, the search moved into Raw Selection's 17-step research process.

The early stages focused on understanding and mapping the market. Relevant companies and competitors were identified, our existing network within the sector was revisited, referrals were gathered and the team built a clearer picture of where executives matching such a specific profile could be found.

The role was also advertised publicly, generating more than 100 applications within the first 24 hours. The volume of interest was so high that the advert had to be taken down.

At the same time, approximately 400 executives across the residential services market were identified and considered before the search was progressively narrowed. The focus increasingly fell on executives from businesses of the appropriate scale, particularly those who had led multi-site operations and combined significant commercial responsibility with genuine experience of the HVAC industry.

One candidate began to stand out during those conversations.

Having come through the trades before moving into leadership, the executive spoke about creating operational playbooks, standardising processes across branches and building organisations that relied upon repeatable systems rather than individual talent. They also spoke about the appeal of building a business for longevity rather than simply building one to sell.

Those experiences closely reflected what the client had described at the beginning of the search.

Part Three: Two Candidates

After weeks of market mapping, conversations, interviews and assessment, two candidates remained.

Both had led businesses of considerable scale. Both understood the challenges of acquisition-led growth. Both demonstrated the operational experience the client had been looking for, and both had performed strongly throughout the process.

The client had confidence in both finalists.

From every conventional measure, the search appeared to have reached a successful conclusion. There were two credible executives capable of progressing into the role, and the final decision appeared to be between two strong options.

Then the situation changed.

Part Four: The Decision

The final stage wasn't another interview.

It was due diligence.

As part of the assessment, Raw Selection conducted independent reference conversations through its own network. These weren't simply references selected and supplied by the candidates. They were conversations with people who had previously crossed paths with the executives and could provide an independent perspective on their track records.

One of those conversations uncovered information that had not been disclosed during the interview process.

It emerged that one of the finalists had been terminated from a previous position.

Given what was uncovered, it was something the team couldn't look past. Despite having progressed through the process and reached the final two, the candidate was immediately withdrawn from the search.

It was a significant moment. Had the assessment stopped with the CV, interviews and candidate-provided information, the client would not have had the same picture when making one of its most important leadership decisions.

For a senior role with a compensation package of approximately $250,000, the consequences of failing to complete that additional due diligence could have been considerable.

Part Five: The Outcome

Removing one finalist didn't automatically make the remaining executive the right appointment.

Their suitability still had to stand on its own.

Throughout the process, however, the successful candidate had continued to demonstrate the characteristics established in the original brief. They had technical credibility from their background in the trades, experience building more consistent operations across multiple locations, significant leadership experience and an approach that closely aligned with what the client was trying to build.

The conversations between the two sides also demonstrated genuine alignment. The candidate understood that scaling a platform wasn't simply about completing more acquisitions; it required building the processes, leadership and operating model capable of bringing those businesses together.

The offer was made and accepted. The successful candidate handed in their notice, and preparations began for them to join the business as its new Chief Operating Officer.

Looking back, perhaps the most interesting part of the search isn't simply who was appointed. It's how close the outcome came to being different.

The final two candidates had made it through extensive research, assessment and interviews. Both had impressed the client. Yet information discovered through an independent conversation fundamentally changed the decision.

For private equity-backed businesses, that distinction matters. The executives appointed to portfolio companies are responsible for turning an investment thesis and value creation plan into results. Understanding what someone has achieved is important, but independently validating how they achieved it, how they led and what happened in previous roles can reveal things an interview never will.

Sometimes, the most valuable part of an executive search isn't the appointment you make. It's the appointment your due diligence prevents.

We've documented every stage of this confidential search, from defining the brief and hunting the market to the two finalists and the reference checks that changed everything.
