Ask most engineering businesses how their hiring is going and they'll quote you a time-to-fill figure: nine weeks, eleven weeks, sometimes worse. It's the wrong number to obsess over. By the time a role is filled, every decision that mattered has already been made. The number that actually decides who you hire is the one almost no-one measures: how long it takes you to put a credible shortlist in front of the hiring manager.
The candidates you want are never on the market for long
Specialist engineering (commissioning, M&E, controls, high-voltage, test) runs on a small pool of genuinely qualified people. A senior commissioning engineer with live project references and current certifications isn't sitting on a job board waiting for you. When they do become available, they're in three or four conversations within a week. Every day a strong CV sits in someone's inbox unactioned is a day a competitor with a faster process is closing them.
This is the part that gets lost in the time-to-fill conversation. You don't lose the best candidates at offer stage. You lose them in the gap between a supplier sending the CV and your hiring manager actually seeing it.
Why most setups are structurally slow
The delay is rarely down to lazy people. It's down to how the work is arranged. The typical specialist engineering employer is running its contingent and permanent hiring across a dozen agencies, an inbox, and a couple of spreadsheets. That arrangement has three built-in delays:
- CVs arrive in different formats, to different people, with no single place they land, so the first thing that happens to a strong candidate is they wait.
- Nobody can see the whole picture at once, so duplicate submissions, ownership disputes and missing compliance get discovered late, after time has already been lost.
- Feedback travels by chase. The supplier emails to ask where their candidate is; the hiring manager replies when they get a moment; the loop takes days when it should take hours.
None of these are dramatic failures. They're small frictions that compound. Add them up across a live requisition and you've handed a fortnight to whoever you're competing with for the same five people.
Measure time-to-shortlist, not time-to-fill
If you only change one thing about how you report on hiring, change the headline metric. Time-to-fill is a lagging number that mixes in notice periods, offer negotiations and a dozen things outside your control. Time-to-shortlist is almost entirely within your control, and it's the leading indicator of whether you'll win the candidate at all.
You don't lose the best engineers at offer stage. You lose them in the gap between the CV arriving and your hiring manager seeing it.
When we benchmark businesses on this, the spread is enormous. The slow end takes seven to ten working days to get three credible, compliance-checked candidates in front of a hiring manager. The fast end does it in under 48 hours. Same roles, same talent pool, same agencies in some cases. The difference is entirely in the process between submission and shortlist.
What a fast process actually looks like
The fast end isn't working harder. They've removed the gaps:
- Every submission lands in one place against the specific vacancy: no inbox, no format lottery, no wondering who has the latest CV.
- Compliance is checked at the point of submission, so right-to-work, certifications and clearances are confirmed before a CV ever reaches a hiring manager. Nothing that isn't ready to interview makes it through.
- The hiring manager sees a clean, comparable shortlist with credentials attached, and gives a decision in the tool, which the supplier sees immediately, with no chasing.
- Spend, ownership and supplier performance are visible the whole way through, so the awkward questions get answered by the system instead of by a meeting.
This is precisely the gap Source Centre was built to close. Not to replace good recruiters or good hiring managers, but to take the dead time out from between them, so the speed of your hiring is set by how fast people can make decisions, not by how long CVs sit in a queue.
The talent pool in specialist engineering isn't getting any deeper. The businesses that win the next few years of hiring won't be the ones paying the most or advertising the widest. They'll be the ones who can look at a strong CV and have it in front of the right hiring manager before lunch.
