Salesforce Developer Interview Questions and Structured Evaluation Guide
Knowing declarative setup isn't enough to call someone a strong Salesforce developer. Good Salesforce developers write bulk-safe Apex, respect governor limits, build Lightning components, integrate with other systems, secure data properly, and know when to use clicks instead of code.
This guide gives you 40 Salesforce Developer interview questions for junior, mid-level, and senior hiring, organized by skill area and experience level, plus a ready-to-use scorecard so every interviewer rates candidates against the same criteria.
What to Evaluate in a Salesforce Developer Interview
Ten skill areas cover what separates a candidate who can configure Salesforce from one who can build scalable, secure, limit-aware solutions.
| Skill Area | What to Assess |
|---|---|
| Data Model and Declarative Tools | Objects, relationships, flows, validation rules, page layouts |
| Apex and Triggers | Classes, trigger patterns, bulkification, exceptions |
| SOQL and SOSL | Queries, relationships, selectivity, governor limits |
| Lightning Web Components | Component structure, data binding, events, wire and Apex calls |
| Asynchronous Processing | Future, Queueable, Batch, Schedulable |
| Testing and Deployment | Test classes, coverage quality, sandboxes, CI/CD |
| Integration | REST and SOAP APIs, callouts, platform events, external services |
| Security and Sharing | Profiles, permission sets, sharing rules, field-level security |
| Problem Solving | Diagnosing limit errors, performance, and data issues |
| Communication | Requirements, documentation, admin and business collaboration |

Questions by Experience Level
Same topics, different depth. Adjust what you ask based on seniority.
Junior Salesforce Developer questions: Foundations first
Salesforce data model, objects and fields, SOQL basics, simple Apex, flows, validation rules, sandboxes
- What is an object in Salesforce?
- What is the difference between a standard and custom object?
- What is a validation rule?

- What is a sandbox?
- What is a flow?
- What is a profile?
Mid-level Salesforce Developer questions: Independent delivery
Triggers and handler patterns, bulkification, Lightning Web Components, asynchronous Apex, testing, integrations
- How would you write a bulk-safe trigger?
- How do you build an LWC that calls Apex?
- How do you write a test class?
- When do you use Batch Apex?
- How do you integrate with an external REST API?
- How do you troubleshoot governor limit errors?
- How do you decide between flow and Apex?
Senior Salesforce Developer questions: System and team level
Architecture, governor limit strategy, integration design, security model, DevOps and CI/CD, mentoring
- How would you design an integration architecture across Salesforce and other systems?
- How do you plan for data volume growth?
- How do you design a secure sharing model?
- How do you set up CI/CD for Salesforce?
- How do you govern customization across a large org?
- How do you mentor developers on limits and patterns?
- How do you evaluate technical debt in an org?
Salesforce Developer Interview Scorecard
Use this so every interviewer scores candidates against the same criteria instead of relying on gut feel.
| Evaluation Area | Weight | What Good Looks Like |
|---|---|---|
| Data Model and Declarative Tools | 10% | Designs models and uses clicks-before-code judgment |
| Apex and Triggers | 20% | Writes bulk-safe, maintainable Apex |
| SOQL and Data Access | 10% | Writes selective queries and handles volume |
| Lightning Web Components | 15% | Builds well-structured, performant components |
| Async Processing and Integration | 15% | Chooses async patterns and integrates reliably |
| Testing and Deployment | 10% | Writes meaningful tests and deploys with discipline |
| Security and Sharing | 10% | Applies secure coding and access design |
| Communication and Collaboration | 10% | Works clearly with admins, business, and engineers |
| Rating | Meaning |
|---|---|
| 1 · Weak | Cannot explain core Salesforce Developer concepts or apply them reliably |
| 2 · Below Expected | Knows some fundamentals but struggles applying them |
| 3 · Meets Expectations | Sound working knowledge, can contribute independently |
| 4 · Strong | Depth, judgment, clear problem-solving, reliable ownership |
| 5 · Exceptional | Expert-level depth, system thinking, strong technical leadership |
What Strong Salesforce Developer Candidates Demonstrate
Look for candidates who can:
- Write bulk-safe Apex and manage governor limits
- Choose flows or code with sound judgment
- Write selective SOQL and handle large data volumes
- Build Lightning Web Components with clean data flow
- Pick the right asynchronous pattern
- Write meaningful tests and use source-driven deployment
- Apply the sharing model and secure coding practices
For senior roles, go deeper on architecture, governor limit strategy, integration design, security model, DevOps and CI/CD, and mentoring.

Frequently Asked Questions
Common questions from hiring teams building a Generative AI Engineer interview process.
Enough to assess the role without turning the interview into a checklist. Most structured interviews work well with 20 to 30 targeted questions across Apex, SOQL, Lightning Web Components, triggers, integrations, security, and governor limits, plus scenario-based problem-solving.
No. Apex matters, but strong interviews also cover the data model, declarative tools, security, integrations, governor limits, testing, and knowing when not to write code.
Certifications show baseline knowledge but don't prove judgment. Use them as one signal and confirm practical skill with scenario questions and hands-on tasks.
Ask about architecture, governor limit strategy, integration design, security model, DevOps and CI/CD, and mentoring.
Yes, adjust the depth. Junior interviews should focus on fundamentals and practical implementation. Senior interviews should weigh design judgment, complex problem-solving, and technical leadership more heavily.
