Agency, in-house or executive search? Choosing the right approach for a technology appointment.

Every hiring manager has been there. A key person resigns, the project deadline doesn't move, and you need to decide quickly how you'll find their replacement. Here's how I'd think it through, having worked in-house, in agency recruitment and now as a specialist consultant.

Start with three questions

Before choosing a recruitment route, be honest about these:

1. How visible is the talent? If good people in this field are actively looking and apply to adverts, you may not need outside help. If the people you want are busy, well paid and not looking, someone needs to go and find them.
2. How much does a delay cost you? An empty seat on a critical project, a security gap or a leadership vacancy can cost far more than a recruitment fee.
3. Who has the time? A good search means writing the brief, sourcing, screening, interviewing, references and managing the offer. If that lands on a hiring manager who already has a full-time job, it usually gets done slowly.

When recruiting yourself makes sense

Recruiting directly works well when your employer brand is strong, the role is a common one, you have an internal talent team with capacity, and you have a few weeks to spare. It's also the right choice for high-volume or entry-level roles, where adverts reliably attract good applicants.

The risk is the hidden cost. Hours of screening, interviews that go nowhere and a long vacancy all add up, even if they never show on an invoice.

When a specialist agency earns its fee

A specialist recruiter is worth using when the skills are scarce, the role is technical enough that a generalist would struggle to assess it, or you need someone quickly. A good specialist brings three things you can't easily build yourself: an existing network of people who trust them, a clear view of what the market is paying, and experience judging technical candidates.

Not all agencies work the same way, so ask how they will actually find people. If the answer is mostly "we'll advertise and search our database", you may get a pile of CVs rather than a shortlist.

Standard, exclusive or executive search?

• Standard: you engage a recruiter on a success basis. It feels low risk, but when several agencies race to send CVs, speed can beat quality.
• Exclusive: one recruiter handles the role for an agreed period. You get their full effort and a single, consistent message to the market, which candidates notice.
• Executive search: a committed, structured search with agreed stages. It suits senior, confidential or genuinely hard-to-fill roles, where you need a thorough market map rather than whoever happens to be looking this month.

The question isn't "agency or no agency". It's "what will it cost us if this role stays empty, or if we hire the wrong person?"

Don't overlook embedded support

If you have a run of roles to fill, there's a middle path: bring a recruiter into your team for a fixed period. They work under your brand, use your systems and can handle both permanent and contract hiring, often more cost-effectively than paying a placement fee on every role.

What good looks like, whichever route you choose

• A clear brief that covers what success looks like after twelve months, not just a list of skills.
• A realistic salary range, checked against the market before the search starts.
• A short, well-organised interview process. Strong technology candidates often have other options.
• Proper, structured reference checks, done with the candidate's consent.
• Honest, prompt feedback for every candidate, including the ones you don't hire.
