30 Most Commonly Asked Salesforce Developer Interview Questions
Basic-Level Salesforce Developer Interview Questions
Q1. What is Salesforce and what are its applications?
A. Cloud-based salesforce salesforce is a CRM platform which assists businesses to manage customer relations, sales, and work processes. For example, they can track leads, automate customer follow-ups, and analyze sales performance all of which helps teams work more efficiently, sell more, and provide better customer service.
Q2. What is Apex? Where is it used?
A. Apex is a strongly typed, object-oriented programming language that enables developers to run flow and transaction control statements on the Salesforce server along with API calls.It is used when the standard functions are not sufficient like when we need to do complex data validation or do backend processing or need to integrate salesforce with other systems using APIs.
Q3. What is the difference between standard objects and custom objects?
A. Standard objects are pre-built by Salesforce like Account, Contact, and Opportunity and they are used universally across organizations. Custom objects are developed to hold the specific business information (e.g., details of a project, inventory) and are used when the business requirements of an organization are unique.
Q4. What are Salesforce Governor Limits?
A. Governor limits are limits imposed by the Salesforce that are allowed to be consumed within the salesforce multi-tenant environment to utilize shared resources. As an example, during bulk data process, they must not issue queries within loops and should use efficient logic to avoid exceeding limits and to avoid prematurely terminating execution.
Q5. What is a trigger in Salesforce?
A. A trigger is an Apex code that executes before and after executing DML operations such as insert, update and delete on the records via database events. For instance, when someone creates a new contact, a trigger could automatically update the associated account information without having to do anything manually.
Q6. What is the difference between workflow, process builder and flow?
A. Workflow is the most basic automation tool and actions are limited. Process Builder has more advanced logic with multiple conditions. Flow is the most powerful as it allows complex automation with user interaction, loops, decision, it is the tool of choice for modern Salesforce automation.
Q7. What is SOQL and SOSL?
A. SOQL can be used to query one object, specific fields of that object, one object with one or more child objects, or one object with one or more parent objects. For example: SOQL will return all contacts on an account, SOSL will search for a keyword across accounts and contacts in one go.
Q8. What are Profiles and Roles?
A. Profiles specify what a user may do (for example, read, create, or edit records) within an application or portal. Roles determine data access within hierarchy. The two work together to give users the right access, keeping security intact while still allowing teams to work efficiently and effectively across the organization.
Q9. What is a Sandbox Environment?
A. Sandboxes are production environment replicas utilized for testing and development. Developers can test new features or bug fixes in isolation to ensure the changes don’t impact real users or business operations prior to moving to live systems.
Q10. What does validation rules mean?
A. Validation ensures that users don’t input invalid data or leave mandatory fields blank. For instance, a user might be blocked from saving a record with a required field left empty, or for email entry such as invalid format allowing flat data to be clean and consistent across the organization.

Q11. What is the difference between Apex Trigger and Apex Class?
A. The apex trigger executes automatically as well when a record is inserted, updated or deleted, it’s event-driven logic. An Apex Class is code that can be reused, and that you call whenever you want. For instance a trigger immediately updates related records, a class processes intricate business logic off line.
Q12. What are Salesforce Relationships?
A. Relationships are used to join objects together in Salesforce. A lookup relationship is a loose connection between two objects, like a contact linked to multiple accounts. A master-detail relationship is much tighter, if you delete the parent record then all associated child records are deleted (think of an order and its order items).
Q13. What is a Batch Apex?
A. Batch Apex allows processing of large amount of data in chunk (s). For instance while updating millions of records, Batch Apex breaks the job into smaller chunks to keep it within governor limits and to avoid performance issues.
Q14. What does a Future Method mean?
A. A Future Method is executed asynchronously, enabling long-running process to be invoked without posing limitations on the user interface. For example, you can use a future method to make an external API call after saving a record.
Q15. What is a Queueable Apex?
A. Queueable Apex is a new feature of the asynchronous proc ess that adds job chaining. You can queue another job, for example, to send notifications after you have processed your customers' data, which is handy for real-time background work runs needing more control than future methods.
Q16. What are Wrapper Classes?
A. Wrapper classes are user-defined classes which contain more than one sObject’s attributes. For instance, showing account information with associated contacts in a single view could be achieved with a wrapper class.
Q17. What does a Lightning Component do?
A. Lightning Components are utilized to design and develop modern, dynamic user interfaces in Salesforce. For example, using Lightning components a custom real-time sales data dashboard with interactive charts can be created to have better user experience.
Q18. What is Visualforce?
A. Visualforce is an outdated framework that developers used to build custom user interfaces in Salesforce. Although it is still present in legacy applications, contemporary applications use Lightning as it offers enhanced performance, responsiveness and user experience over Visualforce pages.
Q19. How do you handle exceptions in Apex?
A. Handling errors in Apex is done with try and catch just like other languages/toolkits so as not to cause any system fault. Such as when adding records, you can catch errors and show friendly messages instead of interrupting the process, leading to a more modular behavior of the app.
20. What is Test Class and Why We Need?
Test Class is necessary to verify apex code and execution on whether it is working fine or not. There is a minimum requirement of code coverage of 75% by salesforce for deployment. E.g., test classes check logic and help stop surprises in production, such as when pushing code to production.

Q21. How do you deal with Governor Limits on real projects?
A. In real projects, I deal with governor limits by bulkifying my code so that I am processing multiple records at a time rather than one record at a time. For example don't put SOQL queries in for loops, and use collections (lists, maps) to improve performance and stay within platform limits.
Q22. What is Bulkification in Apex?
A. Bulkification refers to the practice of writing code that takes into account processing multiple records at a time. Rather than process a single record at a time, I rely on loops, collections, and optimized SOQL queries to make my code run more efficiently in bulk (such as when performing etc. data loading or updating).
Q23. Difference Between Before And After Triggers (Real-time Scenario)
A. Before triggers operate to update or validate values before they are stored in the database such as changing field values. After triggers execute once the records have been saved and are generally used to perform activities such as updating related records or sending notifications during real-time business processes.
Q24. What Salesforce integration options are available?
A. Salesforce supports integration with REST and SOAP APIs. For example, REST API is popularly used for lightweight web based integrations such as connecting mobile applications, and the SOAP API is used in enterprise systems that require exchanging of structured data and that have more stringent security requirements.
Q25. What is Salesforce DX?
A. Salesforce DX provides a better development lifecycle model which improves collaboration and DevOps. Allowing developers to work with version control, automate deployments, and manage environments efficiently, it makes the development lifecycle faster, more organized, and more appropriate for real-world projects.
Q26. What are Named Credentials?
A. Named Credentials securely store authentication information for external integrations. For example, when a developer is connecting Salesforce to an external API, they can use Named Credentials to not have to hard code the usernames and passwords – allowing for secure and maintainable API communication in applications that run in real-time.
Q27. What are Platform Events?
A. Platform Events let you implement event-based integration within Salesforce itself, as well as between Salesforce and external systems. For example, an event can trigger updates to multiple systems immediately when a new order is placed which facilitates building scalable and real-time integrations across different applications.
Q28. What is the difference between manual sharing and sharing rules?
A. Sharing rules provide a means to open up data visibility on a more consistent basis as they are used to share/access records based on roles and other criteria automatically. Manual sharing: It is the record sharing on case-by-case basis, the users have the control to share a record, but it’s not in real time and takes effort.
Q29. How do you optimize SOQL queries?
A. To make my SOQL query performant , I only fetch what I need, use proper filters, and I do not query unnecessarily within loops. For instance, use of indexed fields in WHERE clauses boosts performance and makes data retrieval faster specially while dealing with huge Amount-Of-Data (AOD).
Q30. Could you describe a real time project you have been associated with?
A. In a recent project, I worked on lead assignment automation. The issue was manual lag, so I created rest Apex triggers and flows to assign leads by region. This made us respond faster and being more productive and that is one example of solving problems pragmatically and building scalable solutions.
Common Mistakes to Avoid in Salesforce Developer Interviews
Here are the a few mistakes you could make and should avoid in your next Salesforce Developer interview:
- Most of the candidates fail to explain live scenarios while answering the questions. The interviewers want you to relate your knowledge to practical scenarios and not just give the theoretical definitions.
- Ignoring the governor limits is a big mistake too. As salesforce is very strict executing limits related, not mention them in your answers can make you look like you don't know the platform.
- Unclear Apex concepts can damage your chances. You should be able to explain triggers, classes, execution flow in a simple language confidently.
- Incomplete understanding of the relationships between objects (like lookup and master-detail) can result in wrong or incomplete answers, especially with questions related to data modelling.
- Writing unoptimized queries in SOQL is a widespread problem. You should be able to query efficiently, if you can’t, it is probably a red flag on how you write code.
Interview Preparation Tips
- Practice daily Salesforce developer interview questions to enhance your accuracy and confidence.
- Concentrate on problem solving in the real world, rather than just "knowing" solutions.
