The safest way to vet a Salesforce developer is to separate certification and training from evidence of production delivery. Trailhead badges and Salesforce certifications demonstrate learning and platform knowledge, but they don’t by themselves prove that someone can safely change a live org, troubleshoot a production defect, design maintainable Apex, build effective Lightning Web Components, or work within integration and release controls.
Use a Five-Part Technical Interview
Ask candidates to walk through five areas, rather than recite terminology:
- Production experience: “Which Salesforce clouds have you worked on in production, what did you personally build, and what was your role?”
- Apex/LWC delivery: “Walk me through one feature from requirement to deployment. What design decisions did you make, and how did you test it?”
- Inherited environments: “If you inherited an unfamiliar org tomorrow, what would you inspect before changing anything?”
- Production troubleshooting: “Describe a production defect you diagnosed. What caused it, how did you fix it, and what changed afterward?”
- Technical ecosystem: “Which APIs, integrations, security controls, testing tools, and deployment methods have you used?”
Verify the Evidence
Where confidentiality allows, request a sanitized architecture or code example, ask the candidate to identify exactly what they personally contributed to a larger project, and use references who can speak to production delivery and reliability. A short practical assessment can help too — give a realistic Apex/LWC requirement and ask for the proposed approach, assumptions, test strategy, governor-limit considerations, security considerations, and a maintainability plan. The exercise should test judgment, not become unpaid production work.
Use a Consistent Scoring Model
| Category | What to Look For |
|---|---|
| Production experience | Specific clouds, features, and personal contribution |
| Apex/LWC depth | Design decisions explained, not just terminology |
| Integration/API experience | Real systems connected, not just training exercises |
| Testing & deployment discipline | Test strategy and release process described clearly |
| Architecture & problem-solving | Trade-offs reasoned through, not memorized |
| Security & platform constraints | Governor limits, sharing rules, and data access considered |
| Communication & team fit | Clear explanation of decisions to a non-technical audience |
Require evidence for each category rather than awarding credit simply for holding a certification. The same scorecard can be applied consistently across employees, contractors, and partner-provided developers.
Vet the Engagement Model, Not Just the Person
Finally, ask who manages the developer, who reviews their code, how technical decisions are documented, what happens during an absence, whether replacement is available, and how the developer will integrate with your internal team. Governance and continuity are legitimate parts of the evaluation — not just hiring speed.
Folio3’s Approach
Folio3’s Salesforce developer hiring offering describes certified, pre-vetted developers with a discovery-to-go-live process, backed by Salesforce development services covering Apex and Lightning Web Components and Salesforce consulting credentials across architecture and data roles. Replacement support is available if a developer isn’t the right fit.
