5 signs your recruitment agency does not understand engineering
Most recruitment agencies will take your engineering vacancy. Fewer will fill it well. Here are the five clearest signs that the agency you are using does not have the sector knowledge to actually help you, and what a specialist approach looks like instead.
1. They send CVs that do not meet the technical requirements
The clearest sign that a recruitment agency does not understand engineering is a consistent stream of CVs that miss the technical brief because the recruiter cannot tell a stress engineer from a structural engineer, or a chemical process project engineer from a construction project engineer. Generalists search job titles; specialists read the brief and screen on discipline.
This is the most common complaint we hear from engineering hiring managers who have used generalist agencies. They receive five CVs, three of which are from candidates who have never worked in the relevant discipline, sector, or type of role.
This happens because the recruiter read the job title, searched their database or LinkedIn for similar titles, and sent whoever responded. They did not read the brief properly. More precisely, they could not read the brief properly, because they do not know the difference between a stress engineer and a structural engineer, or between a project engineer in construction and a project engineer in chemical processing. The titles look similar. The jobs are completely different.
If you are consistently receiving CVs that miss the mark on technical requirements, the agency does not understand what you need. Briefing them more carefully will help marginally. Changing agency will help more.
2. They cannot hold a technical conversation
A recruiter who genuinely understands engineering can have a conversation with you about the role that goes beyond the job description. They ask why you need the role, not just what the role involves. They probe on team structure, project pipeline, and technical environment. They push back on requirements that are unrealistic.
Test this directly: ask them to explain the difference between FEA (finite element analysis) and FMEA (failure mode and effects analysis). Ask them why your CSCS card requirement matters and what level is relevant. Ask them what the current market rate is for a six-year experience mechanical design engineer in your region, from their last three placements in that bracket.
If the answers are vague, hedged, or wrong, you have your answer. A specialist knows these things without looking them up.
3. Their salary benchmarks come from job boards
Job board salary data from Indeed, Totaljobs, or Reed lags actual market movement by three to six months and includes aspirational figures from unfilled roles. A specialist quotes what their last three placements in that role type and region actually closed at, not rounded national averages.
Salary data from Indeed, Totaljobs, or Reed reflects advertised salaries from the last three to six months. Advertised salaries are a lagging indicator of what is actually closing in the market. They also include aspirational figures from employers who did not fill at that rate, which skews the data upward or downward depending on the sector.
Live placement data from a specialist agency is more accurate because it reflects what candidates actually accepted last quarter, not what was posted. If your recruiter quotes you benchmarks in round numbers that match national job board averages, they are not drawing on their own placement data.
A straightforward question settles this: “What did your last three placements in this role type and region actually close at?” A specialist has that answer. A generalist does not.
4. They measure success in CVs sent, not quality of hire
The volume-of-CVs metric is a legacy of a model where agencies were paid partly for activity. It is not a useful measure of quality, and agencies that use it as a performance signal are structured around throughput rather than outcome.
Sending you eight CVs a week is easy. Sending you three strong candidates, all of whom understand the role, have been genuinely briefed on your business, and are motivated to make the move for the right reasons, takes significantly more work and much better market knowledge.
Ask prospective agencies how they measure success. If the answer focuses on speed and volume rather than placement longevity, interview-to-offer conversion rate, or repeat client use, that tells you something about their priorities.
5. They disappear after placement
The guarantee period is designed to protect you if a hire leaves quickly. But some agencies treat the end of the guarantee period as the conclusion of their obligation, and only make contact when they want to work on the next vacancy.
A specialist who genuinely understands your business stays in contact because they have a stake in the outcome beyond the fee. They want to know how the placement is settling in at 90 days. They pass on relevant market intelligence when they come across it. They have told candidates things about your business, your culture, and your expectations that they are accountable for now that the person has joined.
What does a specialist approach look like?
A specialist engineering recruitment approach is defined by pushing back on unrealistic briefs, quoting placement data from the last three closed roles rather than job board averages, and briefing candidates on technical context rather than job titles alone. Specialists refer work outside their sector competence instead of attempting to fill it.
The hallmarks are different in every conversation. A good engineering recruiter tells you things you do not want to hear: that your salary band is too low, that your requirement for fifteen years’ experience is eliminating 90% of the qualified pool, or that your three-stage interview process is too slow for the current market.
They push back not because it is comfortable, but because they know the market well enough to be confident in their view. They brief candidates thoroughly, which means candidates arrive at interview understanding the technical context, not just the job title. They refer work they cannot do well and do not try to fill roles outside their sector competence.
