structural intake: the maths behind sustainable recruitment

6 mins’ read time

Tadaah team meeting

Structural recruitment means you don’t pay for and wait on individual vacancies, but build up a continuous stream of suitable candidates through data-driven campaigns and a strong employer brand. The maths is simple: every week that a key role remains vacant costs money, whilst a structured approach shortens the time taken to fill the role and reduces the cost per hire.

Does this sound familiar? You post another job advert online, pay the placement fee again, and after eight weeks of searching, you’re almost back to square one. This stop-start cycle may seem inexpensive each time, but it adds up to surprisingly high costs. You can work out the figures below.

What is structural staff recruitment?

Structural recruitment is a continuous flow of qualified candidates that you don’t have to actively seek out each time. Rather than launching a separate campaign for each vacancy, you keep your target audience data, campaigns and employer brand consistently active.

The difference compared with ad-hoc recruitment lies in the rhythm and reusability. With ad-hoc recruitment, every vacancy starts from scratch: new copy, a new budget, a new learning curve. With structured recruitment, you build on what has worked before, such as tried-and-tested campaign angles and a pool of latent jobseekers.

For SMEs with hard-to-fill roles in engineering, industry, logistics, sales and the maritime sector, this is the difference between putting out fires and planning ahead. Would you like to know what this approach involves? Read about Data-driven recruitment in practice.

How much does one-off recruitment actually cost?

Recruiting for individual vacancies costs more than just the advertising budget. The biggest cost is often hidden: the lost production, turnover or overtime during the weeks that a post remains vacant. These recruitment costs continue to accrue for as long as you are recruiting.

The labour shortage makes this even more urgent. Engineering, construction and industry have for years been among the sectors with the most hard-to-fill vacancies, according to the UWV’s Labour Market Tension Indicator (UWV, 2024). The tighter the market, the longer a recruitment drive takes and the higher the ongoing costs.

What costs do employers overlook?

Employers often only factor in recruitment costs and overlook the rest. A fair calculation takes into account the full chain of time, failed attempts and lost production.

  • Hours spent by hiring managers and HR staff on screening and interviews
  • Ongoing loss of production or turnover whilst the site remains open
  • Overtime or hiring expensive agency staff as a stopgap measure
  • The cost of a mismatch: a wrong hire who leaves after a few months
  • Restart costs: advertising again and going through the learning curve all over again

According to Statistics Netherlands (CBS), there were still hundreds of thousands of unfilled vacancies in the Netherlands at the end of 2024 (CBS, 2024). Every unfilled key position included in that figure represents a counter that keeps ticking.

What does the maths behind sustainable recruitment look like?

The cost analysis for sustainable recruitment does not compare the price per advert, but the total cost per hire over the course of a whole year. As soon as you have a consistent, recurring recruitment need, a structured approach almost always proves more effective than one-off campaigns.

This table illustrates the difference in approach between the two models. The figures are for illustrative purposes only; it is the ratio that matters.

Aspect One-off recruitment Structural intake
Starting point for each vacancy Starting from scratch every single time Building on proven campaigns
Average completion time Often long and unpredictable On average, 3 to 8 weeks
Transparency of costs Only placement visible A clear overview of the total costs per intake
Quality of the shortlist You rate all the comments yourself Only the 2 to 4 best candidates each month
Repetition effect Costs will remain the same or rise Costs per hire decrease over time

“Employers are often alarmed by the costs that keep mounting whilst a post remains vacant. As soon as we make those costs clear, the decision to adopt a structural approach is quickly made,” says an account manager at FosFor. Would you like to see that calculation for your situation?

How do you build up a steady flow of new students?

You build up a steady flow of candidates by linking target audience data, campaigns and your employer brand, and by continually fine-tuning your approach. It is not a one-off exercise, but a cycle that becomes more effective with each passing month.

  1. Analyse your target audience using data. Find out where your candidates are and what really matters to them. Employers often discover, through data, that candidates have different preferences to what they expected.
  2. Refine your employer’s narrative. Turn your job advertisement into a message that resonates with professionals, rather than a dry list of duties.
  3. Run targeted campaigns across multiple channels. Reach latent jobseekers via Meta, Google, LinkedIn and TikTok, not just active jobseekers.
  4. Measure and adjust on a weekly basis. Analyse which adverts generate applications and optimise them for performance.
  5. Ensure quality through pre-selection. Let a comprehensive shortlist filter out the noise, so that you only speak to the very best candidates.

This cycle is central to our data-driven approach and the TEAM framework. Each step feeds into the next, ensuring that your pool of suitable candidates continues to grow.

What are the practical benefits of a steady influx?

A structured recruitment process results in shorter recruitment times, less time spent on applicants and a more attractive employer brand. As you build on previous campaigns, the cost per hire decreases the more frequently you recruit.

In practical terms, this means: vacancies that are filled within 3 to 8 weeks on average, and interviews with only the 2 to 4 best candidates each month. Data from hundreds of recruitment campaigns makes this predictability possible, rather than having to guess each time.

In tight-knit sectors such as shipbuilding, this difference is greatest. Where welders, pipeworkers and ship’s electricians are in short supply, a structured approach pays off the quickest.

Frequently Asked Questions about structural intake

What is the difference between ad hoc recruitment and structural recruitment?

With one-off recruitment, you start each vacancy from scratch with a new budget and new job adverts. With continuous recruitment, you build up a steady stream of candidates using reusable campaigns and data. This reduces the cost per hire and shortens the time taken to fill vacancies when recruitment needs arise again.

Is a structured recruitment process more expensive than posting individual job vacancies?

On a one-off basis, posting job vacancies may seem cheaper, but the total cost per hire is often higher due to lengthy application processing times and lost production. A structured recruitment process brings these hidden costs to light and is generally the most cost-effective option for recurring recruitment.

How quickly do you see results from a structured approach?

Using a data-driven approach, vacancies are filled within 3 to 8 weeks on average. The real benefit lies in repetition: each campaign generates data that enables the next one to run more quickly and with greater precision, resulting in a more stable intake.

Does a structured recruitment process also work for small SMEs?

Yes. A structured approach is particularly worthwhile for SMEs with hard-to-fill roles, because by using target audience data and targeted campaigns, you can compete on visibility and company culture rather than just salary. You don’t need a large budget to recruit consistently.

For which sectors is structural recruitment most valuable?

This applies particularly to sectors facing structural labour shortages: engineering, manufacturing, construction, logistics, sales and the maritime sector. The scarcer the profiles, the longer a one-off recruitment drive takes and the greater the benefits of a continuous influx of talent.
