Structured search instead of gut feeling
Structured HLKS profiles, EU hosting, no scraping. A person decides.
- Qualification, software, standards and German level are fields, not free text. We search for dipl. Techniker HF with Plancal Nova, not for keywords.
- Data sits on servers in the EU. We inform every person at first contact about source and purpose (GDPR Art. 14, revDSG Art. 19).
- No dossier goes out automatically. A recruiter decides after the call whether and to whom we present a profile.
Technology: processor with EU hosting, named in the privacy policy.
Questions before the first call
What does placement cost?
We name the conditions in the first call and in writing in the offer before the briefing. For candidates, placement is free of charge.
What happens if the person leaves during probation?
You get a replacement at no further cost, or a refund, within the guarantee period agreed in the offer. So far it has not been needed: 8 of 8 completed placements passed probation. The conditions are in the terms.
How long until the shortlist?
An estimate in the briefing and the status every week, rather than a number we have not measured. The duration depends on role, Kanton and salary band.
Do you work exclusively, or do candidates sit with three firms at once?
No profile sits with three firms at once: we present it only for the job the person has agreed to. We do not require exclusivity from you; we recommend it because parallel searches approach the same people twice.
How do you handle data?
Candidates learn your firm only before the first interview. EU hosting, no scraping, information at first contact, deletion six months after the process ends. Data processing agreement on request.
Switzerland or Germany: do you understand both markets?
Yes, in the vocabulary of each market: HLKS, Pensum, Lohn in CHF and SIA in Switzerland; TGA, Gehalt, HOAI and works council in Germany. Skill Reveal GmbH in Münster is the contracting party for Germany. The 8 of 8 passed probations are Swiss jobs; three placements in Cologne started in 2026 and are in probation.
Do candidates from Germany need a permit?
No obstacle for EU/EFTA nationals: Bewilligung B with a contract of 12 months or more, Bewilligung G as cross-border commuters. No language certificate is required; we still check German B2/C1 in the first call.
