• ‍Problem: A job title like "electrician" doesn't tell Logi-Technic which technical roles a candidate can actually fill and the strongest candidates don't wait around.
• ‍Solution: Ringtime screens every applicant by WhatsApp and phone, captures the sub-specialty depth and routes them to the right technical recruiter.‍
• Result: One screening qualifies a candidate across a whole skill cluster and books the interview, within minutes, any day or hour.

"Electrician" is not something you can screen on

An electrician who wires an apartment block is not automatically ready to install a bank of public EV chargers and neither of them is necessarily the person who brings a factory production line up to the right voltage. Same trade, very different jobs. For a technical staffing company, the title on the application barely narrows things down.

So the screening has to go deep enough to tell those profiles apart and it has to happen fast, because skilled technicians don't wait around. They applied to a few agencies in one sitting and take the first real conversation that comes back. By the time a recruiter works down the call list the strongest ones are already talking to someone else.

That is the bottleneck Logi-Technic set out to close. As a technical outsourcing company inside House of HR, the constraint was never the number of vacancies. It was screening a scarce technician properly and reaching them before a competitor did.

Their goal: answer first, every time. The moment someone applies, Ringtime reaches out on WhatsApp, asks the questions that matter for the role, checks experience and availability and hands the recruiter a clear summary. Evenings, weekends, the middle of a busy week.

What most agencies get wrong: they screen the vacancy and not the skillset of the candidate

Most staffing agencies screen a candidate against the single vacancy they applied to. If that role is filled or the fit is off, the conversation ends and the candidate goes cold, even when they are right for three other openings.

Logi-Technic flipped that. The screening unit is the bucket: a cluster of roles that share the same core qualifications. A candidate who applies to one maintenance role gets screened against the whole electrical cluster. The posting they applied to is only the entry point.

That only works if the screening captures the detail underneath the trade. Being a qualified electrician is the entry ticket. Whether someone has wired residential installations, commissioned public charging infrastructure or worked on industrial production lines at the right voltage decides which vacancies in the cluster they actually fit. The screening captures that level of specificity, so qualifying once opens up every vacancy the candidate is genuinely right for.

This is deliberate. In technical staffing the scarce resource is qualified people, so re-screening the same electrician every time a new vacancy lands wastes the one thing in short supply. Cross-vacancy routing is the point.

The buckets sit in a tree the agent walks during the call. Three branches at the top, Industry, Construction and Infrastructure and Engineering, then nine skill clusters underneath: electrical, mechanical, electromechanical, rolling stock, residential electricity, construction, maintenance and automation engineering and work preparation. The first questions on the call place the candidate in the right branch. The rest are specific to their cluster.

How the screening runs

Logi-Technic plugged Ringtime in on top of Salesforce with Connexys, their system of record. When a candidate applies, the trigger fires from Salesforce and Ringtime takes the first contact.

The agent is called Lou. The flow runs in two screening stages before any recruiter time is spent:

1. WhatsApp knock-out. A short set of qualifiers: language, driving licence, location, technical background. Clear deal-breakers get caught here, on the channel candidates answer in minutes.
2. Voice screening. Lou calls the candidate, places them in the right branch and asks the cluster-specific questions: what training they did, years in the technical sector, which domain, willingness to work shifts. The conversation runs in Dutch, French or English.

What Lou never does is decide. Every answer goes back to a recruiter and the go or no-go on a candidate stays with a person. That human decision is not a nice-to-have; under the EU AI Act, a recruiter has to own it. Ringtime hands over the evidence, the summary, the structured answers, the transcript and the recruiter makes the call.

A positive screening does not just land in a queue. Each technical recruiter at Logi-Technic owns a specific set of vacancies, which usually means a specific next step: a technical interview, often with a hands-on skills test at a particular site. So the booking is a routing decision. Lou matches the candidate's profile to the recruiter who covers those vacancies and books the interview on that recruiter's calendar, at their location. Borderline cases go to a talent acquisition specialist who picks up where Lou left off, with the full conversation already on file.

Built with the people who run the screenings

The cluster questions weren't written in a vacuum. Logi-Technic's recruiters talk to candidates every day, so they know the follow-ups and the nuances that make a screening actually useful. They shaped the questions and the tone the agent uses, from day one of the project rather than after launch.

To move fast, the teams tested the screening flow before the technical ATS integration was finished, using those early runs to tune Lou's tone of voice and the cluster-specific questions while the wiring was still in progress. By the time the integration lands, the conversation itself is already dialled in. That is what turns a long setup into a quick go-live.

What it changes for the team

The recruiter's morning stops being a list of numbers to dial. It starts with candidates who already said yes, already qualified, with the full conversation on file. The recruiter picks each one up warm and spends the recovered hours on the people worth a real call.

One screening reaches further here than at most agencies, because it qualifies the candidate to the whole skill cluster. The team absorbs more inflow without adding headcount.

FAQ

How does Logi-Technic screen technical candidates?

Every applicant is contacted automatically over WhatsApp the moment they apply, with a short knock-out check on language, driving licence, location and technical background. Candidates who pass get a voice call from the Ringtime agent, which asks role-specific questions and books the interview. A recruiter makes the final decision.

Which languages does the screening run in?

Dutch, French and English. Ringtime supports 22+ languages across voice and WhatsApp.

Does the AI decide who gets hired?

No. The agent gathers evidence: a summary, the structured answers, and a transcript. A recruiter owns the go or no-go. Under the EU AI Act, a human has to make that decision.

Can one screening qualify a candidate for several vacancies?

Yes. Logi-Technic screens at the level of a bucket, a cluster of roles that share the same core qualifications, so a candidate who qualifies is eligible for every vacancy in that cluster they fit, not only the role they applied to. The screening captures the specifics, for example residential wiring versus public EV charging versus industrial voltage, that decide which vacancies actually match.

How does the agent decide which recruiter a candidate goes to?

Each technical recruiter owns a specific set of vacancies, often with its own technical interview and on-site skills test. The agent matches the screened candidate to the recruiter who covers the vacancies they fit, and books the interview on that recruiter's calendar, at their location.

In technical staffing, the candidate who gets a reply tonight is the one who interviews next week. Logi-Technic stopped leaving that to whoever happened to be free to dial. See how Ringtime works, or get screened by the agent yourself to hear the conversation from the candidate's side.
