Salesforce Developer Interview Questions
We have provided a list of carefully selected Salesforce Developer Interview questions below. We have covered questions about platform, development, integrations, and LWC. You can choose to go through them in your preferred order.
1. What declarative tools can we use to customize a Salesforce instance?
Declarative tools are like building blocks in Salesforce that allow us to customize the platform without writing code. We’ve got custom fields and custom objects, which let us define our data structure. Then there are page layouts and Lightning app builder, which help us design how our records look and feel without diving into code.
Now, if we want to automate things without code, we can turn to Flow. Although we used to rely on Process Builder and Workflow Rules, Salesforce is moving away from them. Flow is the way to go for building automation without code.
2. When would we choose programmatic development over declarative?
If we need to get things done quickly and easily, declarative tools are our go-to. They’re great for more straightforward tasks and save us a ton of time.
But when things get complex, that’s when we switch to programmatic development—specialized business processes or scenarios where performance and fine-tuning the user experience are critical. Coding gives us the power to do more intricate stuff and optimize performance.
3. What is the Salesforce release model?
Salesforce rolls out significant updates three times a year: Spring, Summer, and Winter. These updates bring in new features and enhancements. About a month before each release, sandbox instances get updated so we can test our customizations before they hit our production environment.
4. What are governor limits? Please provide some examples.
Governor limits are like guardrails in Salesforce that prevent us from hogging up too many resources. They keep our processes in check, ensuring fair usage in a shared environment.
For example, we’ve got limits on the number of SOQL queries we can run, the amount of data we can process in one go, and the number of HTTP callout requests we can make in a single transaction.
5. How can you prevent duplicate records in Salesforce?
To prevent duplications of records in Salesforce, the following steps are taken:
To keep duplicate records at bay, we set up Duplicate Rules in Salesforce.
- Head to setup and search for Duplicate Rules.
- Please create a new rule and pick the object you want to apply it to.
- Set up the criteria for identifying duplicates.
- Decide what happens when a duplicate is found – like blocking the creation of duplicate records or letting users know.
- Save and activate the rule, and you’re good to go!

6. What Salesforce-supported development tools are there?
When it comes to developing on Salesforce, we’ve got Salesforce Extensions for VS Code, which is like our coding playground. It works hand in hand with the Salesforce Command Line Interface, giving us all the tools we need to write, test, and deploy our code.
7. What are the three types of object relationships?
There are three main types of object relationships in Salesforce:
- Lookup Relationship: This links two records by having one record point to another through a lookup field.
- Master-Detail Relationship: Similar to lookup, but with a twist – the child record depends on the parent. If the parent goes, so does the child.
- Self-Relationship: This is like a lookup, but it points back to the same object. It’s handy for creating hierarchies or chains of related records.

8.What is the difference between Master details & Lookup relationship?
Here are the critical differences between master details & lookup relationships:
9. What is SOQL and its purpose?
SOQL stands for Salesforce Object Query Language, and as the name suggests, it is the primary language used for performing queries against the database. While its syntax is similar to SQL, there are a few key differences, mainly in that SOQL is exclusively used for retrieving data(i.e., SELECT statements).
It retrieves data from a single object and those directly related to it. SOQL can be used both within Apex code – to query records for consumption by code – or via the API and tools that use it – such as in data loader tools. Eg.
List<Contact> contacts = [SELECT Id FROM Contact Where AccountId = : accountId];

10. What is the role of the Validation rule in Salesforce?
Validation rules are necessary to ensure the accuracy and consistency of data in Salesforce. They are like the gatekeepers of our data. They make sure that the data going into Salesforce meets certain criteria or follows specific rules. It’s all about keeping our data clean, consistent, and error-free.
They can used to play the following roles:
- Data type check
- Code check
- Range check
- Format check
- Consistency check
- Uniqueness check
- Presence check
- Length check
- Lookup
11. What is required to deploy Apex code to a production instance?
When Apex code is deployed to production, there are a few things which are not compulsory but as part of best practice we need to make sure of:
- All classes and triggers must be compiled successfully.
- Tests should cover at least 75% of the Apex code, and there should be no test failures.
- Triggers must have at least 1% test coverage.
12. What programming languages can we use to customize a Salesforce instance?
To customize Salesforce, we primarily use Apex, which is like Java but for Salesforce’s server-side tasks. On the front end, we have Lightning Web Components as the leading technology, followed by older ones like Aura Components and Visualforce. These technologies use HTML, CSS, JavaScript, and Apex. Additionally, we can use Flow, a low-code language for both front-end and back-end customization.
13. What are the different events for an Apex Trigger?
Apex Triggers have different events they can respond to:
- Before triggers run before a record is saved, it is helpful for validations.
- After triggers run after a record is saved, it is useful for post-saving tasks.
Triggers are then further broken down into the type of operation that invokes it. These are insert, update, delete, and undelete. This allows the triggers to be customized and invoked only when explicitly required.
14. What is the difference between Triggers and Flows?
Triggers and Flows differ in several ways, such as:
- Coding is required in the Trigger, but in the case of Flow, it is not.
- A trigger is executed after the Flow.
- In Trigger, there is a need to manually write the test class, while in Flow, there is no need for it at all.
- There is a clear pictorial presentation of logic in Flow to build it.
- If you want to develop a complex trigger, then go with the apex trigger.

Basics of Triggers
15. What is a global Apex class?
A global Apex class is one accessible from any Apex code within any namespace. We use global classes sparingly, typically for managed packages or Apex REST web services. Global Apex class should rarely be used and only implemented when explicitly necessary, e.g., within managed packages or for Apex REST web services.
16. What is an Interface, and why would we use one?
An Interface in Apex is like a blueprint for classes, defining method signatures without implementations. We use interfaces to enforce a standard method structure across different courses, allowing for flexible behavior based on context.
It is helpful for abstracting method declaration from its specific implementation. A typical example of this can be found with batch classes, which implement the standard Salesforce database interface. Batchable.
17. How can we integrate into external REST web services?
To integrate with external REST web services, we usually use HTTP callouts to communicate with their APIs. We build request payloads using classes like JSON and XMLStreamWriter that match the API requirements.
18. How can an external system integrate into Salesforce?
External systems can integrate with Salesforce using its REST API. This allows them to perform actions like creating, updating, or querying records. A connected app can also be used to request access to Salesforce data on behalf of an external application. It must be integrated with the Salesforce API using the OAuth 2.0 protocol.
19. How can we secure credentials used for outbound integrations?
Depending on the type of credentials, we have a few options. The most preferred is Named Credentials, which specify the base endpoint and the authentication credentials. These are chosen since Salesforce then handles the authentication for us and keeps the credentials away from prying eyes.
Alternatively, if named credentials are not suitable, we could choose to store the credentials in a Custom Metadata type, which will allow different credentials to be used across various environments. We can secure the permissions to access the metadata type. We should never hard-code the credentials for integrations within our code as this is very insecure.
20. What is the difference between LWC and Aura components?
Lightning Web Components is built using current web standards to build custom HTML elements through Web Components, designed to run in a lightweight and performant manner.
Aura components are the legacy Lightning Component framework but still utilize JavaScript and HTML for development.
21. Why would we use Lightning Web Components over Aura components and vice versa?
Ideally, we should always use Lightning Web Components for any new developments due to their easier development and better performance. We should only use Aura components if we wish to use a piece of functionality that still needs to be supported in LWCs; in this case, we should wrap an LWC inside of an Aura component.
22. Where can we use Lightning Components?
Lightning components can be used in various parts of your Salesforce org. These can be decided by administrators or added by developers. You can deploy Lightning components in the Utility Bar, integrate them into Outlook and Gmail, and use them in Flows, Visualforce pages, external web pages, pre-chat snap-ins, and quick actions.
23. What is SLDS?
The Salesforce Lightning Design System (SLDS) is like the user interface toolkit for Salesforce Lightning. It helps developers design, style, and build the user interface components of Salesforce applications.
Developers can use SLDS-provided CSS styles or component markup templates to create custom components that maintain a consistent look and feel across the Salesforce platform. SLDS also guides accessibility, language, and icons.
24. What is a roll-up summary field?
A rollup summary field is a particular type of field in Salesforce that sits on the master side of a master-detail relationship. These fields automatically calculate their values based on the aggregate data from the detail records.
For example, a rollup summary field might calculate the sum, count, or maximum value of related documents. This saves developers from having to write Apex code to perform these calculations manually.

25. How can we enforce Sharing Rules within our Apex code?
To enforce Sharing Rules within Apex code, we can define our class to use the “with sharing” or “without sharing” keywords in its definition. Alternatively, we can use the “inherited sharing” keywords, which inherit the sharing settings from the calling class. This allows us to dynamically handle sharing rules based on the context in which the code is executed.

Sharing Rules in Salesforce
26. What are Custom Metadata Types, and why would we use them?
Custom Metadata Types are like custom objects, but they are metadata. They allow you to create your metadata types with custom fields. We use them to store configuration data that we don’t want to hardcode in our code, making it easier to change settings without modifying code.
27. What is dynamic Apex?
Dynamic Apex allows you to write code that can adapt to different circumstances at runtime. For example, you can use dynamic Apex to create and execute SOQL queries or DML statements based on user input or other factors.
28. How can we enforce Field Level Security (FLS) within our Apex code?
To enforce Field Level Security (FLS) in Apex, we can use the Schema class to check if a field is accessible to the current user before performing any operations on that field. This helps prevent unauthorized access to sensitive data.
29. When should we bypass sharing and FLS within our code?
We should only bypass sharing and FLS within our code when it’s necessary for the business requirements and when we’ve thoroughly considered the security implications. This should be done sparingly and with caution, as it can expose sensitive data to unauthorized users.
30. How can we secure dynamic SOQL?
To secure dynamic SOQL, we should always use variable binding to prevent SOQL injection attacks. This means using placeholders in the query string and binding variables to those placeholders to ensure that user input is sanitized correctly and doesn’t allow malicious code execution.
Also, use the escapeSingleQuotes method to sanitize user-supplied input. This method adds the escape character (\) to all single quotation marks in a string that is passed in from a user. The method ensures that all single quotation marks are treated as enclosing strings, instead of database commands.

31. What’s the difference between queueable Apex, batch Apex, and schedulable Apex?
- Queueable Apex: It allows you to execute long-running processes in the background asynchronously. You can chain queueable jobs together and monitor their progress.
- Batch Apex: It is used to process large amounts of data in smaller batches to avoid hitting governor limits. It’s ideal for tasks like data cleansing or data migration.
- Schedulable Apex: It allows you to schedule Apex classes to run at specific times or intervals. You can use it for tasks like generating reports or sending email notifications on a recurring basis.
Code-Based Salesforce Developer Questions & Answers
32. Write an Apex trigger to update a field on a related record when an Opportunity is closed.
Following is an Apex Trigger to update the Status_c field on a related Account record when an Opportunity is closed.
trigger UpdateAccountOnOpportunityClose on Opportunity (after update) {
OpportunityHelper.updateRelatedAccounts(Trigger.new, Trigger.oldMap);
}
public class OpportunityHelper {
public static void updateRelatedAccounts(List newList, Map oldMap) {
Set accountIds = new Set();
for (Opportunity opp : newList) {
Opportunity oldOpp = oldMap.get(opp.Id);
if (opp.IsWon && (oldOpp == null || !oldOpp.IsWon) && opp.AccountId != null) {
accountIds.add(opp.AccountId);
}
}
if (!accountIds.isEmpty()) {
List accList = [
SELECT Id, Status__c
FROM Account
WHERE Id IN :accountIds
];
for (Account acc : accList) {
acc.Status__c = 'Customer';
}
update accList;
}
}
}
33. Explain the difference between @AuraEnabled and @InvocableMethod annotations in Apex.
@AuraEnabled and @InvocableMethod both expose Apex to external callers, but they serve different purposes and have different rules.
@AuraEnabled: Used to expose Apex methods to Lightning Components (Aura & LWC) and also to Flow (when marked as invocable variables or using Apex-defined types).
- Supports both static and instance methods.
- Can return complex types, collections, and even custom Apex classes.
- Methods can be marked as cacheable=true for client-side caching in LWCs.
- Typically used in UI-driven interactions, such as retrieving or updating records from a Lightning component.
Example:
@AuraEnabled(cacheable=true)
public static List getAccounts() {
return [SELECT Id, Name FROM Account LIMIT 10];
}
@InvocableMethod: Specifically designed to expose Apex to Flow and Process Builder.
- Methods must be static and must accept a list of a specific type (List of sObjects or List of custom classes).
- You can have only one invocable method per Apex class.
- Intended for business automation, not UI interactions.
- Returned data must also follow strict type rules.
Example:
public class AccountActions {
@InvocableMethod
public static void updateRatings(List accounts) {
for (Account acc : accounts) {
acc.Rating = 'Hot';
}
update accounts;
}
}
34. Given a JSON response, write an Apex class to parse the data and store relevant details.
This class parses a JSON string and stores the data in Apex variables.
public class ParseJSONExample {
public String name { get; set; }
public Integer age { get; set; }
public static ParseJSONExample parse(String jsonString) {
return (ParseJSONExample) JSON.deserialize(jsonString, ParseJSONExample.class);
}
}
35. How do you bulkify an Apex trigger? Provide an example answer.
I prefer to use maps and lists instead of DML inside loops to bulkify an Apex Trigger. Example:
trigger UpdateAccountOnOpportunityClose on Opportunity (after update) {
Map accountsToUpdate = new Map();
for (Opportunity opp : Trigger.new) {
Opportunity oldOpp = Trigger.oldMap.get(opp.Id);
// Check for stage change to 'Closed Won' and ensure AccountId is not null
if (opp.StageName == 'Closed Won' && oldOpp.StageName != 'Closed Won' && opp.AccountId != null) {
accountsToUpdate.put(opp.AccountId, new Account(
Id = opp.AccountId,
Status__c = 'Customer'
));
}
}
if (!accountsToUpdate.isEmpty()) {
update accountsToUpdate.values();
}
}
36. Write a SOQL query to fetch all Contacts related to Accounts whose Industry is “Technology.”
The following SOQL query fetches all Contacts related to Accounts whose Industry is “Technology”:
SELECT Id, Name FROM Contact WHERE AccountId IN (SELECT Id FROM Account WHERE Industry = 'Technology')
37. Implement a Batch Apex class that processes records in chunks of 200.
Here is a Batch Apex class that processes records in chunks of 200:
global class BatchExample implements Database.Batchable {
global Database.QueryLocator start(Database.BatchableContext BC) {
return Database.getQueryLocator(
'SELECT Id, Status__c FROM Contact'
);
}
global void execute(Database.BatchableContext BC, List scope) {
List contactsToUpdate = new List();
for (SObject sObj : scope) {
Contact c = (Contact) sObj;
c.Status__c = 'Updated';
contactsToUpdate.add(c);
}
if (!contactsToUpdate.isEmpty()) {
update contactsToUpdate;
}
}
global void finish(Database.BatchableContext BC) {
// Optional: Post-processing logic like logging or sending an email
}
}
“To Execute the batch use this:”
Database.executeBatch(new BatchExample(), 200);
38. How would you write a test class for an Apex controller that fetches Account records?
Here is how I would fetch account records via test class:
@isTest
private class AccountControllerTest {
@isTest static void testGetAccounts() {
// Create test data
Account acc = new Account(Name = 'Test Account');
insert acc;
Test.startTest();
// Call the controller method (must be static)
List accounts = AccountController.getAccounts();
Test.stopTest();
// Assert result
System.assertNotEquals(0, accounts.size(), 'Expected at least one account returned');
}
}
39. Write an Apex class to make a callout to an external REST API and parse the response.
Here is an Apex Class to make a callout to an external REST API
public class APICalloutExample {
@future (callout=true)
public static void makeCallout() {
Http http = new Http();
HttpRequest req = new HttpRequest();
req.setEndpoint('https://api.example.com/data');
req.setMethod('GET');
try {
HttpResponse res = http.send(req);
if (res.getStatusCode() == 200) {
String responseBody = res.getBody();
System.debug('Response: ' + responseBody);
} else {
System.debug('Callout failed with status: ' + res.getStatus());
}
} catch (Exception e) {
System.debug('Callout exception: ' + e.getMessage());
}
}
}
40. Demonstrate how you would use Map and Set collections in Apex.
Here is how I would use map and set collections in Apex:
Map priceMap = new Map{'ProductA' => 100, 'ProductB' => 200};
Set products = new Set{'ProductA', 'ProductC'};
41. How would you efficiently query large data sets in Salesforce using SOQL?
To efficiently query large data sets in Salesforce using SOQL, I would use Database QueryLocator for batch processing since it streams results and is resilient to large data volumes.
Or I would use Order by RecordId and then use Limit.
1. Batch Apex with Database.QueryLocator
- Use Database.getQueryLocator(<soql>) inside Database.Batchable.start()
Example skeleton
global class LargeQueryBatch implements Database.Batchable {
global Database.QueryLocator start(Database.BatchableContext bc) {
return Database.getQueryLocator(
'SELECT Id, Name, Status__c FROM CustomObject__c WHERE Status__c = \'Active\' ORDER BY Id'
);
}
global void execute(Database.BatchableContext bc, List scope) {
// process scope (max ~200 per execute)
}
global void finish(Database.BatchableContext bc) { }
}
2. Order by Id, then LIMIT
- Ordering by Id is safe; avoid OFFSET for huge datasets because OFFSET has a 2,000-row limit. For pagination, use Id ranges or QueryLocator cursors.
- Example: page where Id > lastSeenId to paginate.
Scenario-Based Salesforce Developer Questions & Answers
42. A business needs to automate assigning new cases to support reps based on workload. How would you design the solution?
To automate the assignment of new cases based on workload and to implement an omnichannel routing approach, a capacity model can be designed. This approach is most efficient, as Omni-Channel is built for real-time workload balancing while respecting the availability and capacity of support agents.
Here’s how I would implement it:
- Optionally use Skills-based routing (skill matching) for specialized cases.
- Enable Omni-Channel in Setup.
- Create Presence Statuses and Presence Configurations for reps.
- Define Service Channels (Case).
- Create Routing Configurations (e.g., least-active, most available).
- Define Capacity Model per rep (e.g., one high-priority + 2 low-priority).
- Configure Queues and assign agents to queues.
43. Your client wants a custom approval process for Opportunities with multiple levels. How would you implement this?
The best way to create an approval process for opportunities with multiple levels is to configure Approval Processes with various steps and implement criteria-based routing.
- This can be done by implementing a Standard Approval Process.
- I will start by creating multiple approval steps, each with entry criteria.
- Steps can be sequential or parallel.
- Approvers can be set to User, Queue, Role, Manager, or a Dynamic Apex-coded approver.
- Use the Approval History related list for tracking.
44. You need to design a solution where data changes in Salesforce trigger external system updates. How would you approach this?
To create a Trigger that updates external systems when a data change occurs in Salesforce, we can try to follow the following approaches:
- Platform Events: These are best for business events, such as an opportunity to move to a different stage. It is a decoupled and asynchronous process that can be published from Flow or Apex. To execute this, I’ll need to use Replay IDs and durable subscribers in Middleware.
- Outbound Messages (Workflow): This approach is suitable for simple, guaranteed delivery. Since it is SOAP-based, make sure it is acceptable. Outbound messages are limited in flexibility and payload format, which can be a hindrance sometimes.
- Apex HTTP Callouts: Synchronous and Asynchronous callouts via Apex are another good approach, which can be executed using @future(callout=true), Queueable, or Batch Apex. Use Named Credentials for secure auth and endpoint management. Note that callouts in transactions can fail and roll back. So it would be better to do callouts after commit (e.g., publish the Platform Event and have the subscriber do the callout).
45. A company wants to track changes to key fields on the Account object. What would you use to accomplish this?
While there are various methods to track changes on the Account object, I would prefer to use either of the following:
- Field History Tracking (built-in): It can track up to 20 fields per object and can show old/new values, who changed them, and the date. It is easy to enable and expose the related Account History related list.
- Custom Audit Object via Trigger: This can be used when you have to track more than 20 fields or capture complex metadata (e.g., before/after snapshots, reasons, IP/location). Implement a before-update trigger that writes changes to Account_Audit__c with OldValue, NewValue, user, timestamp, and a reference to execute this process.
- Event Monitoring: This approach is used for user activity and broad audit needs with a Shield add-on.
46. A Salesforce application is experiencing slow performance due to complex SOQL queries. How would you optimize them?
There could be various reasons for slow performance when executing complex SOQL queries. To optimize this, we first need to figure out the root cause. This can be done by using selective filters that leverage indexed fields to reduce the number of fields queried, using efficient query patterns (e.g., avoiding nested loops), leveraging caching where appropriate, and monitoring governor limits.
- Use Query Plan Tool: Evaluate cost and get recommendations (indexes, selective filters).
- Make filters selective: use indexed fields in the WHERE clause—indexes: standard (Id, OwnerId, lookup) or custom index (support request). Avoid !=, NOT IN, OR across different fields — they break selectivity.
- Add custom indexes where needed: Submit case to Salesforce Support for additional custom indexes or use External ID to auto-index.
- Avoid functions on fields: WHERE LOWER(Name) = ‘x’ turns off the index. Store normalized fields instead.
- Reduce returned columns: Only SELECT required fields (avoid selecting large text/blobs unnecessarily).
- Avoid nested loops in Apex: Use maps/sets to bulkify and reduce repeated queries.
- Use proper pagination: Use QueryLocator, LIMIT, and Id range pagination instead of OFFSET.
- For reporting/analytics use Async SOQL or Reporting snapshots: Offload heavy aggregations to async or external BI.
- Use Skinny Tables & Denormalization for reports: When joins across many large objects slow reports significantly.
- Cache where valid: For lookup or reference data that’s stable, cache in client or platform cache.
Example fix: If WHERE Email__c =: email is slow and Email__c is not indexed — add index or use External ID.
47. A user reports that they can’t access certain records even though they are assigned the appropriate profile. How would you troubleshoot this?
The preferred method for troubleshooting this would be to check the Sharing Rules, Role Hierarchy, OWD, and Record Owner settings.
- Check if the record is owned by a user outside the role.
- Check whether the automatic group-based sharing is enabled in Sharing rules.
- Check whether the user’s role grants them implicit access in the Role Hierarchy.
- Check if the record has a public or private OWD.
48. How would you ensure data integrity when integrating Salesforce with an external system?
I would use the following methods to ensure data integrity while integrating Salesforce with an external system.
- Validation & Schema enforcement: This approach will include implementing validation rules, required fields, picklist constraints, and data type checks in Salesforce and Middleware.
- Error handling & retries: I would implement retry policies with exponential backoff and maintain a dead-letter queue for manual review. I will log all failures with context, such as what is causing the error, with timestamps.
- Data cleansing & deduplication: I will run cleansing jobs before migrating data and integrating with any external system. To duplicate any records, I would implement matching rules and duplicate rules.
49. What considerations would you keep in mind while implementing a Lightning component that interacts with an Apex controller?
- Security: Enforce CRUD and Field-Level Security in Apex (server) — don’t rely solely on client-side checks. Use Schema.sObjectType methods to check access or Security.stripInaccessible().
- Bulkification: Apex methods should accept lists and process in bulk; avoid single-record operations in loops triggered by the client.
- Governor limits: Minimize queries, use maps to avoid N+1, and batch server-side operations. For extensive processing, use Queueable/Batch Apex invoked by the component (and provide UI feedback).
- Error handling & UX: Return meaningful error messages and surface them in the element. Use @AuraEnabled exceptions mapped to client-side toast messages.
51. Your team needs to implement a dynamic dashboard that adapts based on user role. How would you approach this?
To implement a dynamic dashboard that adapts to user roles, I will customize visibility settings for each role.
The built-in Salesforce Dynamic Dashboards can run as the logged-in user and display data based on user access. But the number of dynamic dashboards can vary by edition, and these dashboards still use reports as data sources.
Whereas building a Lightning page containing reports or custom LWC components is a better approach. I will use component visibility filers such as role, profile, or permission to show or hide specific components.
52. A company wants to migrate large volumes of data from an external system to Salesforce. What strategies would you use to optimize the migration?
To optimize the migration of large volumes of data, I would prefer to use Data Loader and ETL tools such as Informatica or MuleSoft. Another good approach is batch processing data from external systems into Salesforce.
ETL tools or Middleware such as Mulesoft, Informatica, Talend, or Pentaho can be practical for transformation, deduplication, and orchestration. At the same time, Data Loader can be used for scripted, repeatable loads and automation. Lastly, tuning batch sizes to 200-10,000 rows, depending on the API/operations, can help move such data. I would keep an eye on heap/class limits for Apex Triggers via this approach.
