To do that, asking the right interview questions for Salesforce developers is essential.

This blog provides a comprehensive guide to the best interview questions, practical test ideas, and talent insights tailored specifically for recruiters and talent acquisition leaders hiring for Salesforce developer roles. Whether you're hiring for CRM customizations, API integrations, or full-stack Lightning work, this guide will help you structure an effective interview process.

What Makes Salesforce Developer Interviews Unique?

Unlike other technical interviews, Salesforce interviews require a nuanced blend of technical fluency, business logic understanding, and an appreciation for platform-specific rules. Since Salesforce developers often operate across multiple roles, they need to be adept in:

• Apex triggers, classes, and test methods
• Lightning Web Components and Visualforce pages
• Data modeling with custom fields, objects, and relationships
• Secure record access via sharing rules and role hierarchy
• Integration with external systems using REST APIs
• Process automation using Flow, workflow rules, and validation rules

Well-crafted interview questions help uncover a candidate's true capabilities, not just what they’ve memorized.

15+ Essential Salesforce Developer Interview Questions

Here’s a categorized list of high-impact interview questions for Salesforce developers to use during the interview process:

Apex and Coding

1. What are the key differences between Apex classes and triggers in Salesforce?
2. Can you give an example of an Apex trigger you’ve written to enforce complex business rules?
3. How do you handle governor limits in large data operations?
4. What is the difference between SOQL and SOSL, and when would you use each?
5. How do you test your Apex code before moving it to production?

These questions evaluate foundational developer skills and knowledge of Salesforce's unique programming language.

Data Modeling and Relationships

6. Describe how you would implement a many-to-many relationship using junction objects.
7. What’s the difference between lookup and master-detail relationships?

These questions uncover an understanding of data types, relationship in Salesforce, and access considerations.

Sharing, Security, and User Access

11. How do sharing rules differ from manual sharing?
12. Explain how you would set up sharing settings to allow a specific group of users access to a record without exposing unrelated data.

Hands-On Tests to Validate Skills

To validate their abilities beyond the interview, you can ask candidates to:

• Create a custom object with validation rules, workflow, and automation.
