Certificates are checked against the role
A certificate only matters when it matches the process, material, voltage, pressure, or safety requirement on the site. Verification links paperwork to the job.
Experience is made concrete
Good screening asks about drawings, tools, previous sites, languages, and the worker's strongest conditions. It avoids sending a general profile to a specialist project.
References reduce uncertainty
Past supervisors, repeat clients, and previous placements give context that a CV cannot show. Reliability, punctuality, and teamwork matter as much as craft skill.
Verification helps workers too
Workers benefit when their strengths are understood. It leads to better matches, fewer rejected starts, and clearer expectations before travel.
