Whether you are a fresher starting your Salesforce journey or an experienced professional preparing for your next role, these carefully curated questions will help you revise the fundamentals and strengthen your confidence.
Below is a human-written, plagiarism-free collection of the most commonly asked Salesforce Developer interview questions, divided into Beginner and Advanced levels.
1. What is Salesforce, and what benefits does it offer to businesses?
A: Salesforce is a cloud-based CRM platform used to manage customer, sales, marketing, and support activities. It is popular because it is secure, scalable, customizable, and reduces infrastructure costs.
2. What is Apex in Salesforce?
A: Apex is Salesforce’s backend programming language used to implement custom logic. Developers use Apex when standard configuration tools are not enough to meet business requirements.
3. What are Triggers in Salesforce?
A: Triggers are Apex programs that automatically run when records are inserted, updated, deleted, or restored. They help enforce rules and automate actions directly at the database level.
4. Why are Governor Limits important in Salesforce?
A: Governor Limits ensure that no single user or process consumes excessive system resources. They encourage developers to write efficient, scalable code that works well in multi-user environments.
5. What is SOQL?
A: Salesforce Object Query Language (SOQL) allows users to retrieve records from Salesforce data objects. It allows developers to query records based on conditions and relationships.
6. What is the difference between SOQL and SOSL?
A: SOQL retrieves records from a specific object, while SOSL is used to search text across multiple objects when the data location is uncertain.
7. What are Salesforce Objects?
A: Objects are database tables in Salesforce. Salesforce provides standard objects, while custom objects are created to store organization-specific data.
8. Can you explain the distinction between Profiles and Permission Sets?
A: Profiles define a user’s core access, while Permission Sets grant additional permissions without changing the profile. Permission Sets offer more flexibility in access management.
9. What is a Salesforce Sandbox?
A: A Sandbox is a copy of the production environment used for development, testing, and training. It allows safe experimentation without impacting live users or data.
10. What are Lightning Web Components (LWC)?
A: Lightning Web Components are modern UI components built using JavaScript and web standards. They provide faster performance and better user experience in Salesforce Lightning.
11. What is Visualforce?
A: Visualforce is a framework used to build custom user interfaces with markup and Apex controllers. It is mostly used in older Salesforce applications.
12. What is a Test Class and why is it required?
A: Test classes help confirm that Apex code runs properly and produces the expected results. Salesforce requires test coverage to ensure stable deployments and prevent unexpected issues in production.

13. What is Bulkification in Apex?
A: Bulkification is the practice of writing Apex code that can process multiple records at once. It helps avoid governor limit errors when large data volumes are processed.
14. What is Asynchronous Apex?
A: Asynchronous Apex allows long-running operations to execute in the background without blocking user actions. It improves performance and user experience.
15. Difference between Future, Queueable, and Batch Apex?
A: Future methods handle simple async tasks, Queueable Apex allows more control and chaining, and Batch Apex is used for processing large datasets in manageable chunks.
16. What are Named Credentials?
A: Named Credentials securely store authentication and endpoint details for external integrations, reducing security risks and simplifying integration logic.
17. What is the MVC architecture in Salesforce?
A: Salesforce follows the Model-View-Controller pattern, where data is managed by objects, the interface by LWC or Visualforce, and logic by Apex controllers.
18. What is a Wrapper Class?
A: A Wrapper Class is a custom Apex class used to combine different data types into a single structure, commonly used for displaying complex data on UI pages.
19. What is the difference between Before and After Triggers?
A: Before Triggers are used to validate or modify data before it is saved, while After Triggers are used when record IDs are required for further operations.
20. What is Field-Level Security (FLS)?
A: Field-Level Security manages user access by controlling visibility and edit permissions for fields. Developers must respect FLS to ensure proper data protection.
21. What is Deployment in Salesforce?
A: Deployment is the process of moving code and configurations from the sandbox to production using tools like Change Sets, Salesforce CLI, or CI/CD pipelines.
22. How does Role Hierarchy work in Salesforce?
A: Role Hierarchy controls data visibility by allowing higher-level roles to access records owned by users below them.
23. What are Governor Limits violations and how can they be avoided?
A: Violations occur when code exceeds resource limits. They can be avoided by bulkifying code, minimizing SOQL queries, and using collections efficiently.
24. What are Salesforce Integrations?
A: Salesforce integrations connect Salesforce with external systems using REST APIs, SOAP APIs, or middleware tools to exchange data.
25. What qualities do interviewers expect from a Salesforce Developer?
A: Interviewers look for problem-solving skills, clean and optimized coding practices, understanding of business workflows, and the ability to explain technical decisions clearly.
