The short answer
Change your approach to a hard-to-fill vacancy based on signals from the process itself. Reach, conversation participation, and candidate quality tell you more than how long the vacancy has been open.
Three signals that call for a change of approach
The first signal: your reach is off. Technical roles are largely filled by people who are not actively looking right now. A job posting on a job board does not reach them. If you are only visible in places where active jobseekers look, you miss the largest group – and that is not a problem with the vacancy itself, but with the channel.
The second signal: your qualification process is breaking down. Candidates come forward, but the conversations that follow take time and yield little. The pre-selection is either too broad, letting everyone through, or too slow, so people drop out before they are reached. If the funnel consumes more time than it produces candidates, the problem lies in the qualification process – not in how attractive the role is.
The third signal: the message is missing the mark. Good candidates drop off at first contact. The job posting does not speak to them, or the initial communication sets the wrong expectation. That calls for different content – not a larger budget.
These three signals point to three different solutions. Mixing them up costs money and time.
What this looks like in practice
Imagine a manufacturing company looking for a production planner with CNC experience. The vacancy has been open for six weeks. Seven applications came in; three candidates turned out not to qualify for the required experience on closer inspection, two dropped off after the first point of contact, and two were never called back.
This is a hypothetical example, but the pattern is familiar. The problem is not a shortage of candidates. It lies in the speed and quality of that first contact – and in the fact that the vacancy only reached people who were actively looking.
Another scenario: a service company posts an advert for an electrotechnical service engineer. Within a week, thirty applications come in, but none of the candidates has the required experience profile. Here, reach is not the problem; qualification is. The job posting casts too wide a net, or the barrier to applying is too low.
Two situations that look similar on the surface. Two entirely different approaches in practice.
Step by step: how to adjust your approach
Step 1 – diagnose before you change anything. Look at what the vacancy has produced so far. How many people responded? What percentage met the basic requirements? Where did candidates drop off? Only once you know that do you know what to adjust.
Step 2 – distinguish reach problems from qualification problems. Low response points to reach. High response but no match points to qualification or the job posting itself. Good initial responses but drop-off afterwards points to the first contact or the speed of follow-up.
Step 3 – consider social recruitment if reach is failing. People in work do not visit job boards. Social recruitment reaches them in their feed, without them actively looking. The content needs to be different from a standard job posting: fewer lists of requirements, more recognition of what the role actually means day to day.

Step 4 – automate qualification if selection is moving slowly. An AI recruiter can hold conversations via WhatsApp 24/7, ask follow-up questions from within the organisational context, and qualify candidates against the agreed job requirements. You receive the result – a conversation transcript, a CV where provided, a score, and suggested follow-up questions – in the Cockpit. The personal conversation is yours to conduct.
Step 5 – evaluate along the way, not just at the end. If you have no usable response after two weeks, that is information. Do not wait until the vacancy has been running for three months before concluding that something is not working.
Frequently asked questions
How long should a vacancy for technical staff stay open before you change something?
There is no fixed timeframe. What counts is the quality of the response, not how long the vacancy has been running. Two weeks without usable applications justify a change of approach sooner than six weeks of steady but below-standard candidates.
Does a different approach always mean a larger budget?
Not necessarily. Sometimes the problem lies in the timing of follow-up or the wording of the first message. That requires no extra budget – it requires a different choice.
When do you bring in an agency instead of adjusting the approach yourself?
If your own approach is consistently producing too little and you want to fully outsource recruitment for a period, an agency may be an option. Recruitment marketing through your own channels – with automated qualification – gives you more control over the process and builds insight that stays with you rather than with an agency.
