Technical/Coding Interview Questions and Answers for Salesforce Developers

These Salesforce coding interview questions are designed for developers with around 3 years of experience. They evaluate proficiency in Apex, Visualforce, and Salesforce data modeling, as well as the ability to write efficient, scalable code that meets complex business requirements.

Question 1: What is a SOQL query and how does it differ from SQL?

Bad Answer 1: SOQL is like SQL; I can use it for anything, like insert or delete.

Good Answer 1: SOQL (Salesforce Object Query Language) is specifically designed for querying Salesforce data. Unlike SQL, it is read-only and cannot perform DML operations like INSERT, UPDATE, or DELETE. SOQL allows filtering, ordering, and aggregate functions on Salesforce objects. Understanding SOQL optimization is crucial to prevent governor limit issues when handling large data sets.

Example SOQL query:

List<Account> accounts = [SELECT Id, Name, Industry FROM Account WHERE Industry = 'Technology' ORDER BY Name LIMIT 100];

Question 2: Explain the concept of Governor Limits in Salesforce.

Bad Answer 2: Governor Limits are just rules; I don’t pay much attention to them.

Good Answer 2: Governor Limits are Salesforce’s way of ensuring fair resource usage in a multi-tenant environment. Limits exist on SOQL queries, DML operations, heap size, CPU time, and callouts. I manage these by bulkifying code, using collections (Lists, Maps, Sets), and avoiding DML inside loops. Monitoring logs and writing efficient queries are essential for maintaining high-performance Apex code.

Question 3: How do you perform upsert operations in Apex?

Bad Answer 3: I just use insert or update depending on the situation.

Good Answer 3: Upsert operations allow creating or updating records based on an external ID or Salesforce record ID. It ensures that duplicates are avoided and data integrity is maintained. Example:

Account acc = new Account(External_Id__c='123', Name='New Account');
upsert acc External_Id__c;

Upsert is critical in Salesforce integrations where data from external systems may already exist in Salesforce.

Question 4: Describe the use of triggers in Salesforce.

Bad Answer 4: Triggers are just for automating things.

Good Answer 4: Triggers automate custom business logic before or after DML operations like insert, update, or delete. They must be bulkified and often leverage helper classes for maintainability. Triggers are ideal for enforcing cross-object validation, workflow automation, and data consistency.

Question 5: What is a custom controller in Salesforce?

Bad Answer 5: A custom controller is just a controller you make yourself.

Good Answer 5: A custom controller is an Apex class providing full control over a Visualforce page. Unlike standard controllers, it allows custom logic, complex data handling, and integrations. Best practices include testing all methods, handling exceptions, and writing maintainable code.

Question 6: Explain the role of test classes in Salesforce.

Answer 6: Test classes ensure Apex classes and triggers function correctly and are mandatory for production deployment. They cover positive, negative, and bulk scenarios, and simulate different user profiles and permissions. Proper test coverage ensures reliable and maintainable code.

Steps I follow for writing test classes:

1. Identify scenarios including edge cases and integrations.
2. Generate test data programmatically.
3. Use assertions to validate expected outcomes.
4. Test with multiple profiles and permission sets.

Question 7: How do you handle exceptions in Apex?

Answer 7: Exceptions are handled using try, catch, and finally blocks. I log exceptions in debug logs or a custom error object. Graceful error handling ensures users receive clear messages instead of system failures.

Example:

try {
    update accounts;
} catch(DmlException e) {
    System.debug('Error updating accounts: ' + e.getMessage());
}

Question 8: What are batch Apex classes and where are they used?

Answer 8: Batch Apex allows asynchronous processing of large datasets. Jobs are divided into manageable chunks with start, execute, and finish methods. They are essential for mass updates, data cleansing, and integration workflows.

Question 9: Describe a scenario where you would use a Visualforce page.

Answer 9: Visualforce is used when custom UI requirements cannot be met with standard pages. For example, a multi-step approval form integrating multiple objects. I combine Visualforce with custom Apex controllers and JavaScript for enhanced UX and dynamic behavior.

Question 10: Explain the use of the @future annotation in Apex.

Answer 10: The @future annotation runs methods asynchronously, which is critical for callouts to external services. It helps maintain transaction limits while processing data in parallel. I design @future methods for bulk-safe and retryable integrations.

Example:

@future(callout=true)
public static void sendDataToAPI(List<Account> accounts) {
    // Integration logic here
}

Question 11: How do you secure Apex code against SOQL injection?

Answer 11: Avoid concatenating user inputs in dynamic queries. Always use binding variables to prevent injections. Example:

String userInput = 'Acme';
List<Account> accts = [SELECT Id, Name FROM Account WHERE Name = :userInput];

This ensures data integrity and security in Salesforce coding.

Question 12: What are the different types of collections in Apex?

Answer 12: Apex provides three primary types of collections, Lists, Sets, and Maps, each serving a distinct purpose in Salesforce coding scenarios.

• Lists are ordered, indexable collections that allow duplicate elements. They are ideal when the sequence of records matters or when you need to access elements by their position. Lists are frequently used for bulk operations, such as processing multiple records retrieved from SOQL queries.
  Example:
  List<Account> accounts = [SELECT Id, Name FROM Account ORDER BY Name LIMIT 100];
accounts.add(new Account(Name='New Account'));
System.debug(accounts[0].Name); // Access first account
• Sets are unordered collections of unique elements, meaning duplicates are automatically removed. Sets are perfect for scenarios where you need to ensure uniqueness, such as storing record IDs to avoid processing the same record multiple times.
  Example:
  Set<Id> accountIds = new Set<Id>();
for(Account a : [SELECT Id FROM Account]){
   accountIds.add(a.Id);
}
System.debug('Unique account IDs: ' + accountIds.size());
• Maps are key-value pairs, where each key maps to exactly one value. Maps are extremely useful for efficient lookups, especially when working with related records. They reduce the need for nested loops, improving performance and governor limit compliance.
  Example:
  Map<Id, Account> accountMap = new Map<Id, Account>(
   [SELECT Id, Name FROM Account]
);
System.debug('Account name: ' + accountMap.get(someId).Name);

Question 13: How do you implement error handling in batch Apex?

Answer 13: I wrap DML operations in try-catch blocks in the execute method to log errors. The finish method is used for notifications or retrying failed records. This ensures robust batch execution.

Steps I follow for batch error handling:

1. Identify operations that might fail.
2. Implement logging for each error.
3. Retry or alert stakeholders in finish.

Question 14: What is the purpose of the Schema Builder in Salesforce?

Answer 14: Schema Builder is a visual tool for creating and modifying objects, fields, and relationships. It simplifies data modeling, dependency tracking, and object management, and reduces errors compared to manual setup.

Question 15: Describe the process of creating a custom web service in Salesforce.

Answer 15: Custom web services are defined using global Apex classes and the webservice keyword. Methods are exposed externally with proper security. Testing includes input validation, exception handling, and SLA checks. These services are critical for ERP or CRM integrations.

Question 16: How can you call an external REST service from Apex?

Answer 16: Use HttpRequest and HttpResponse classes. Configure endpoint, headers, and HTTP method, then send using Http.send(). Handle timeouts and errors.

Example:

HttpRequest req = new HttpRequest();
req.setEndpoint('https://api.example.com/data');
req.setMethod('GET');
Http http = new Http();
HttpResponse res = http.send(req);
System.debug(res.getBody());

Question 17: What is the purpose of the with sharing keyword in Apex?

Answer 17: Sharing enforces record-level access rules. It ensures users only access records they are authorized to see. This is crucial for secure business-critical processes.

Question 18: Explain how you can debug Apex code.

Answer 18: Debugging uses the Developer Console, debug logs, or IDE tools. I monitor variable values, track execution, and isolate logic issues. Effective debugging is key in Salesforce coding interview questions.

Question 19: What is a wrapper class in Apex?

Answer 19: A wrapper class combines data from multiple objects or adds custom attributes for UI or processing purposes.

Wrapper class example:

public class AccountWrapper {
    public Account acc {get; set;}
    public List<Contact> contacts {get; set;}
    public AccountWrapper(Account a, List<Contact> c) {
        this.acc = a;
        this.contacts = c;
    }
}

It improves UI flexibility and code reuse.

Question 20: How do you ensure that an Apex class is deployable to production?

Answer 20: Ensure 75% code coverage and passing unit tests. Cover bulk, positive, and negative scenarios, and follow best practices. Test in sandbox or staging environments to avoid production errors.

5 Tricky Salesforce Developer Interview Questions and Answers

Question 1: How do governor limits influence Salesforce Apex development, and how can they be mitigated?

Answer 1: Governor limits enforce multi-tenant resource fairness, meaning that even correct code can fail if it exceeds limits. Tricky scenarios arise with large data volumes, recursive triggers, or complex batch processes. Mitigation strategies include:

• Bulkifying operations to handle multiple records in a single transaction.
• Using Maps and Sets to reduce redundant queries and DML operations.
• Avoiding DML inside loops and combining updates.
• Leveraging asynchronous processing (Batch Apex, Queueable Apex, or @future) for high-volume operations.
• Selective SOQL queries with indexed fields to prevent full table scans.

A tricky edge case: combining synchronous and asynchronous processes can still hit cumulative limits if not carefully monitored.

Question 2: What is the role of Lightning Web Components (LWC), and how do they differ from Aura Components?

Answer 2:  LWCs use modern web standards (ES6, Shadow DOM, custom elements) to provide better performance, modularity, and maintainability. Compared to Aura:

• LWCs have smaller runtime overhead and faster rendering.
• Aura supports older patterns and more built-in events but is heavier.
• LWCs encourage strict separation of UI and Apex logic, reducing coupling.

Tricky scenario: Mixing Aura and LWC components in the same page can cause event propagation or lifecycle timing issues, which must be debugged carefully.

Question 3: How do you debug complex issues in Salesforce with multiple triggers, flows, and workflows?

Answer 3: Debugging in multi-layered orgs is tricky because multiple automation tools can act on the same record simultaneously. Strategies include:

• Use the Developer Console to filter logs by transaction ID or user.
• Systematically disable triggers or flows in a sandbox to isolate behavior.
• Implement System.debug statements and custom logging objects to track data changes across triggers.
• For flows, enable debug mode and checkpoints.

Edge cases: Recursive updates, after/before trigger conflicts, and future/queueable calls can make root cause analysis non-obvious.

Question 4: What strategies ensure data consistency when integrating Salesforce with external systems?

Answer 4: Maintaining consistency across systems is challenging due to timing, partial failures, or API limitations. Effective strategies include:

• Middleware orchestration (e.g., MuleSoft, Dell Boomi) to handle retries and transformations.
• Integration patterns like request-response, batch processing, or event-driven (Platform Events).
• Validation rules and triggers in Salesforce to enforce business rules.
• Idempotent operations to avoid duplicate records during retries.

Tricky scenario: When external systems asynchronously update Salesforce, ensuring referential integrity requires careful orchestration and monitoring of out-of-order events.

Question 5: How do you handle asynchronous processing in Salesforce for large-scale operations?

Answer 5: Large-scale asynchronous operations are tricky because limits differ for synchronous vs asynchronous contexts. Techniques include:

• Batch Apex for processing millions of records in manageable chunks.
• Queueable Apex for chainable, stateful jobs.
• Platform Events for event-driven integrations or near real-time updates.
• @future methods for fire-and-forget operations.

Tricky edge case: Mixing multiple async methods can exceed concurrent job limits; scheduling and chaining jobs must be done strategically to avoid conflicts.

This section of tricky Salesforce developer interview questions goes beyond basic syntax, testing a candidate’s ability to tackle complex, real-world scenarios in Salesforce.
