Ground every answer in facts on this page and the original listing. We never invent Glassdoor-style reviews or salaries that are not in our data.

Interview prep

Be ready to walk through EC&I drawing sets you have produced—SLDs, layouts, cable schedules, loop diagrams—and how you managed revisions and mark-ups.

• Explain your CAD/modelling tools and how you keep models aligned with 2D deliverables.
• Describe coordination with electrical and instrumentation engineers and other draughting teams.
• Expect practical questions on drawing standards, layering, layer naming, and checking for completeness before issue.

Fit summary

Best suited to candidates who already draft or model EC&I work accurately, follow revision discipline, and can work on-site in Centurion (not remote). Strong fit if you prefer production drafting/modelling over pure design authority or site supervision.

Day in the role

As an EC and I Draughtsman / Modeller at C3 Resources Investments in Centurion, a typical day centres on electrical, control, and instrumentation drawings and 3D models for plant or project work.

• Produce and revise single-line diagrams, cable schedules, layouts, and instrument loop drawings from redlines and engineer input.
• Build or update models so drawings stay consistent with site constraints and discipline interfaces.
• Check standards, revision control, and clash or coordination notes with engineers and other draughting disciplines.
• Issue packs for review, construction, or as-built updates rather than owning field construction decisions.
