Basic Level Salesforce Developer Interview Questions
Start your preparation with these beginner-friendly Salesforce developer interview questions and answers.
- What is Apex in Salesforce, and how is it used?
Apex is Salesforce’s object-oriented programming language. It’s used to write custom logic on the platform. Developers use Apex to create triggers, classes, batch jobs, and integrations. It runs in a multi-tenant environment and follows strict governor limits.
- Explain the difference between a trigger and a workflow.
Triggers are code-based and run before or after DML events. Workflows are point-and-click tools for automation. Triggers allow complex logic, while workflows are limited to field updates, tasks, and emails. Workflows are also being replaced by Flow.
- What are governor limits in Salesforce?
Governor limits restrict the amount of resources a transaction can use. This keeps shared systems stable. Examples include limits on SOQL queries, CPU time, and DML operations. Developers must write efficient code to avoid hitting these limits.
- What is a SOQL query? How is it different from SOSL?
SOQL stands for Salesforce Object Query Language. It’s used to fetch records from a single object or related objects. SOSL (Salesforce Object Search Language) can search multiple objects and fields at once. SOQL is for targeted data. SOSL is for keyword searches.
- How do you create a custom object in Salesforce?
Go to Setup – Object Manager – Create – Custom Object. Give it a label, plural name, and API name. Add fields, relationships, and set permissions. You can now use it like any other standard object.
- What is a validation rule? Can it fire before or after a trigger?
A validation rule stops saving invalid data. It runs before the record is saved. So it always fires before a trigger. It checks specific conditions using formulas and shows an error if they’re true.

Salesforce Developer Fresher Interview Questions
These interview questions for SFDC developer roles are perfect for freshers looking to land their first job in Salesforce.
- What are standard objects and custom objects in Salesforce?
Standard objects are built-in ones like Account, Contact, and Opportunity. Custom objects are created by users for specific needs. They store unique data that’s not covered by standard objects.
- How would you explain Salesforce architecture to someone new?
Salesforce is a multi-tenant cloud platform. It runs on metadata-driven architecture. That means all customizations are stored as metadata. It supports APIs, automation tools, and built-in security. Everything is browser-accessible with no local installation needed.
- Can you write a basic Apex class and method?
Yes. Here is a simple example:
public class HelloWorldClass {
public static String sayHello() {
return ‘Hello, Salesforce’;
}
}
This method returns a basic greeting string.
- What is a sandbox, and why is it used?
A sandbox is a testing environment. It’s used to build and test changes safely. You can try features without touching live data. Once tested, changes can be moved to production.
- What are the different types of relationships in Salesforce?
Salesforce supports Lookup and Master-Detail relationships. Lookup is a loose link – optional and no impact on deletion. Master-Detail is stricter – child records depend on the parent. There’s also many-to-many using junction objects.
- How do you deploy changes from sandbox to production?
Use Change Sets, Metadata API, or third-party tools. Add components in the sandbox, upload them to production, and validate before deployment. You must test everything before the final push.
Advanced Level Salesforce Interview Questions for Experienced Developers
Here are Salesforce developer interview questions for experienced professionals to tackle complex scenarios.
- What is the use of @future, and when should you avoid using it?
@future is used to run Apex code asynchronously. It’s helpful for callouts or long operations that shouldn’t block the user. But it can’t return values, runs in its own context, and doesn’t support chained calls. Avoid using it when order matters or when you need the result immediately.
- How would you handle large data volumes in a trigger?
I bulkify the code to process records in batches. Avoiding SOQL or DML inside loops is critical. I also use collections like maps and sets to handle data efficiently. For very large operations, I offload logic to batch classes or queueable Apex.
- Explain the lifecycle of a Lightning Web Component.
The key phases are –
- Constructor runs first
- connectedCallback() is called when added to the DOM
- renderedCallback() is fired after rendering
- disconnectedCallback() is called when it is removed
State changes or user actions may cause re-rendering.
- How do you manage error handling in batch Apex jobs?
I wrap logic in try-catch blocks inside the execute method. If a record fails, I log the error and move on to the next. For debugging, I store failed record IDs and messages in a custom object or send them via email.
- What’s the best way to integrate Salesforce with an external REST API?
Use HttpRequest and HttpResponse classes in Apex. Define a named credential for secure access. Parse the JSON using JSON.deserialize(). Always handle status codes and timeouts to avoid runtime issues.

Scenario Based Salesforce Developer Interview Questions
This section includes scenario-based interview questions for SFDC developers and their answers.
- A trigger is causing CPU timeouts during data loads. What will you check first?
I would check if the trigger is bulkified. Then I would look for SOQL or DML inside loops. I would also check recursion and whether related triggers or processes are firing. Reducing logic in the trigger and moving it to a helper class helps.
- A user reports that a validation rule is blocking a critical update. What’s your approach?
First, I would review the rule’s condition. Sometimes it needs a bypass for specific users or profiles. I would ask if this update is frequent or rare. If it’s an exception case, I might add a checkbox or a bypass field controlled by admin.
- How would you troubleshoot a failed scheduled batch job?
I would check Apex Jobs in Setup for error logs. Then I would look into the batch class for unhandled exceptions. Wrapping logic in try-catch helps. I would also verify if the data meets the filter conditions. If needed, I would run it manually in sandbox.

}
global void execute(Database.BatchableContext bc, List<SObject> scope) {
List<Account> accounts = (List<Account>)scope;

acc.Name += ‘ – Processed’;
