1. How would you optimize Apex code to handle bulk processing and avoid hitting governor limits?

When optimizing Apex code for bulk processing, I focus on processing records in bulk rather than one by one. Salesforce imposes governor limits to ensure efficient use of resources, so it’s important to design the code accordingly. I usually collect records in a list or map, then perform DML operations on those collections. For example, instead of updating each record in a loop, I would gather all records in a list and run a single update operation outside the loop. This avoids hitting the DML statement limit.

To further optimize my code, I make use of SOQL for loops, which process query results in smaller batches. This helps prevent hitting the governor limit on the number of SOQL queries. Another best practice I follow is implementing asynchronous processing methods, such as future methods, batch Apex, or queueable Apex for larger data volumes, ensuring that governor limits are respected even when processing large datasets.

2. Can you explain the difference between a trigger and a workflow rule, and when you would use each in Salesforce?

A trigger is written in Apex and allows developers to implement complex business logic that executes before or after record events such as insert, update, or delete. Triggers are highly customizable and enable actions like updating related records, handling complex validations, or integrating with external systems. For example, I often use triggers when multiple records need to be updated in response to changes in a single record, something a workflow rule cannot handle.

In contrast, a workflow rule is a declarative automation tool used for simpler tasks such as updating fields, sending email alerts, or creating tasks. I prefer using workflow rules when the automation logic is straightforward and doesn’t require complex logic. For instance, if I need to send an email notification when a field changes or update a field based on a specific condition, I would use a workflow rule. If more advanced automation is needed, like updating related records or custom logic, triggers would be the better choice.

3. Describe your experience working with Salesforce Lightning components. How do you handle events in LWC (Lightning Web Components)?

I have extensive experience working with Salesforce Lightning components, particularly Lightning Web Components (LWC). LWC is a modern framework built on web standards that allows developers to build responsive and efficient UI components. I’ve used LWCs to create dynamic interfaces that interact with backend Apex controllers for data fetching and complex business logic. For example, I once built a custom component to display filtered account records, where users could adjust filters and see live results without reloading the page.

Handling events in LWC is straightforward yet powerful. Components communicate through the publish-subscribe pattern using custom events. For instance, if a child component needs to notify the parent about a user action, I create a CustomEvent and dispatch it. In the parent component, I add an event listener to capture the dispatched event. Here’s a basic example of handling events:

// Child component (childComponent.js)
handleButtonClick() {
  const event = new CustomEvent('buttonclick', { detail: { message: 'Hello from Child' } });
  this.dispatchEvent(event);
}

// Parent component (parentComponent.js)
handleButtonClick(event) {
  console.log(event.detail.message); // Outputs 'Hello from Child'
}

This modular event handling makes it easy to build reusable, maintainable components that follow best practices for separation of concerns and scalability.

4. How do you handle exceptions in Apex? Provide examples of handling different types of exceptions.

In Apex, handling exceptions is essential to ensure the application runs smoothly and users receive clear feedback in case of errors. I primarily use try-catch blocks to manage exceptions gracefully. For example, in a DML operation, I would wrap the code in a try-catch block to catch any DMLException that may occur due to issues like validation rule violations or field constraints. Here’s a simple example:

try {
  insert newContact;  // Insert a contact record
} catch (DmlException e) {
  System.debug('Error while inserting contact: ' + e.getMessage());
}

This ensures that the error is caught and logged, and I can handle it appropriately, such as displaying a user-friendly error message. Besides catching system exceptions like NullPointerException or QueryException, I also create custom exceptions when needed. For instance, if a business rule is violated, I throw a custom exception to provide more specific error messages.

Additionally, I sometimes use the finally block in scenarios where I need to execute code regardless of whether an exception occurred. This is useful for cleaning up resources or sending notifications after an operation, ensuring that the application continues to run smoothly and efficiently, even when unexpected errors arise.

5. What is the difference between before and after triggers in Salesforce? In what scenarios would you use each?

Before triggers in Salesforce are executed before a record is saved to the database. They are primarily used to validate data or update fields on the same record that is being processed. For example, if I need to automatically populate a field on a record before it gets inserted or updated, I would use a before trigger. This is because changes made in before triggers are directly applied to the record without requiring an explicit DML statement.

After triggers, on the other hand, execute after the record has been saved to the database. These are used when the logic depends on the record already existing in the database, such as when working with related records or performing DML operations on other objects. For instance, if I need to create or update child records based on a change in the parent record, I would use an after trigger. In these cases, since the record is already committed to the database, I can safely reference the record’s ID and work with related objects.

6. Explain how you would implement complex business logic in Apex. How do you ensure scalability and maintainability?

To implement complex business logic in Apex, I break down the logic into modular components, ensuring that each piece of logic is encapsulated within reusable methods or classes. This makes the code more maintainable and easier to troubleshoot. For example, instead of writing all logic directly in a trigger, I follow the trigger handler pattern where triggers simply delegate tasks to handler classes. This approach helps me manage trigger recursion, control bulk operations, and maintain cleaner code.

In addition, I focus on writing bulk-safe and governor limit-aware code by processing data in collections. For scalability, I leverage batch Apex or queueable Apex for long-running operations, especially when processing large datasets. This prevents governor limits from being hit and ensures the system performs efficiently. I also make use of custom metadata and custom settings to externalize configuration data, allowing business rules to be modified without altering the underlying Apex code.

Finally, I follow Salesforce’s best practices such as using SOQL queries efficiently, optimizing DML operations, and writing comprehensive test classes to ensure code coverage and quality. This ensures that the solution remains scalable as the system grows, and the code is easy to maintain and update as business requirements evolve.

7. What are some best practices to follow when writing test classes in Salesforce to ensure high code coverage?

When writing test classes in Salesforce, my goal is to ensure not only high code coverage but also to validate that the code works as expected in various scenarios. One of the first best practices I follow is to create realistic test data within the test class itself. Salesforce requires at least 75% code coverage for deployment, so I create data that mimics real-life business cases and edge cases. By using test data created within the test class (instead of relying on actual org data), I ensure the tests are independent and won’t break if production data changes.

Another key practice is to cover both positive and negative test scenarios. For positive tests, I check that the code works under expected conditions, while for negative tests, I simulate failures, such as validation rule violations or governor limits, to verify that the code handles errors correctly. I also make use of the @testSetup method to create common test data that can be reused across multiple test methods, which not only improves efficiency but also ensures that the tests run faster.

I also focus on testing bulk operations by inserting or updating multiple records in test methods to ensure that the code handles bulk processing properly. This helps to simulate real-world data volumes and ensures that the code is optimized for Salesforce’s governor limits. Here’s an example of a simple test class:

@isTest
private class AccountTriggerTest {
    
    @testSetup
    static void setupTestData() {
        List<Account> accList = new List<Account>();
        for(Integer i = 0; i < 200; i++) {
            accList.add(new Account(Name = 'Test Account ' + i));
        }
        insert accList;
    }
    
    @isTest
    static void testAccountTrigger() {
        List<Account> accsToUpdate = [SELECT Id FROM Account LIMIT 200];
        for(Account acc : accsToUpdate) {
            acc.Name = 'Updated Name';
        }
        Test.startTest();
        update accsToUpdate;
        Test.stopTest();
        
        // Add assertions to validate the expected behavior
        System.assertEquals('Updated Name', [SELECT Name FROM Account LIMIT 1].Name);
    }
}

This ensures that my code handles bulk operations efficiently and passes test coverage requirements while maintaining system performance.

8. Can you explain the role of the Database.SaveResult class and how you use it in DML operations?

The Database.SaveResult class is crucial when you need to handle DML operations that might partially succeed or fail. Instead of using standard DML operations like insert or update, I often use Database methods like Database.insert or Database.update with the allOrNone flag set to false. This allows me to process records in bulk while still handling errors gracefully. The SaveResult class stores the outcome of each record operation, including whether it succeeded or failed, along with the associated error message if there was a failure.

For example, when inserting a list of accounts, if one of the records fails due to validation rules or missing fields, the SaveResult allows me to capture the error and continue processing the other records. Here’s an example of using Database.SaveResult in an insert operation:

List<Account> accounts = new List<Account>();
accounts.add(new Account(Name = 'Valid Account'));
accounts.add(new Account()); // Missing required fields

Database.SaveResult[] results = Database.insert(accounts, false); // allOrNone = false

for (Database.SaveResult result : results) {
    if (result.isSuccess()) {
        System.debug('Account inserted successfully: ' + result.getId());
    } else {
        System.debug('Error inserting account: ' + result.getErrors()[0].getMessage());
    }
}

In this scenario, the first account is inserted successfully, while the second fails due to missing required fields. By using Database.SaveResult, I can handle these errors without stopping the entire transaction, ensuring that valid records are still processed.

9. How do you implement asynchronous processing in Salesforce? Explain different techniques such as future methods, batch Apex, and queueable Apex.

Asynchronous processing in Salesforce is essential for managing long-running or resource-intensive operations without hitting governor limits. I typically use different techniques based on the use case. One of the simplest approaches is using future methods. Future methods allow me to run code asynchronously, particularly when integrating with external systems or making callouts. Future methods are lightweight but have limitations, such as not returning results to the caller.

For more complex or larger-scale processes, I use batch Apex. Batch Apex processes large volumes of records by breaking them into smaller chunks and processing each batch separately. This is especially useful when handling large data sets or performing data-intensive operations, like mass updates. Batch Apex can process up to 50 million records in Salesforce, making it ideal for high-volume data operations.

Another technique I frequently use is queueable Apex. It’s more flexible than future methods and allows for chaining jobs, which is useful when I need to execute a series of operations in sequence. Queueable Apex also provides more control over job execution and better error handling than future methods. Here’s a simple example of queueable Apex:

public class MyQueueableJob implements Queueable {
    public void execute(QueueableContext context) {
        // Perform some asynchronous processing
        List<Account> accs = [SELECT Id, Name FROM Account LIMIT 100];
        for(Account acc : accs) {
            acc.Name = 'Updated by Queueable';
        }
        update accs;
    }
}

Queueable Apex is my preferred choice when I need better control over asynchronous processes but don’t require the full capabilities of batch Apex.

10. What is SOQL injection, and how can you prevent it in your Apex code?

SOQL injection is a security vulnerability where a malicious user manipulates SOQL queries by inserting unexpected data into query strings, potentially exposing or modifying data they shouldn’t have access to. To prevent SOQL injection, I never directly insert untrusted user inputs into a dynamic SOQL query. Instead, I use binding variables, which safely pass input values into the query, eliminating the risk of injection.

Here’s an example of how to prevent SOQL injection using binding variables:

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

In this example, the user input is bound to the SOQL query using :userInput, which prevents any malicious input from altering the query. If I need to use dynamic queries, I always sanitize inputs or validate them using escapeSingleQuotes and other input validation methods to ensure the system is protected from injection attacks.

11. How do you handle integrations between Salesforce and external systems? Share your experience with REST/SOAP APIs.

When handling integrations between Salesforce and external systems, I typically rely on both REST and SOAP APIs depending on the needs of the external system. For simpler, lightweight integrations, I prefer using the REST API due to its ease of use, performance, and scalability. I’ve worked on multiple projects where I integrated Salesforce with external applications like payment gateways or CRMs using RESTful web services. For instance, I’ve implemented a solution where Salesforce sent order data to an external system and received updates on shipment statuses using REST endpoints.

For more complex or legacy systems, I use SOAP API as it provides robust support for WSDL and XML payloads. I’ve integrated Salesforce with enterprise-level applications like ERP systems, where SOAP-based web services were the preferred method. In such cases, I would generate Apex classes from the WSDL and use those to handle the communication between Salesforce and the external system. I ensure secure communication by configuring authentication mechanisms like OAuth or session-based tokens and manage API limits to avoid hitting Salesforce’s governor limits.

Here’s a basic example of making a REST callout in Salesforce:

HttpRequest req = new HttpRequest();
req.setEndpoint('https://api.example.com/payment');
req.setMethod('POST');
req.setHeader('Content-Type', 'application/json');
req.setBody('{"orderId":"12345","amount":"100"}');

Http http = new Http();
HttpResponse res = http.send(req);

if(res.getStatusCode() == 200) {
    System.debug('Payment processed successfully: ' + res.getBody());
} else {
    System.debug('Error in payment processing: ' + res.getStatus());
}

For more complex integrations, especially with older systems, I use SOAP APIs. SOAP handles larger payloads in XML format and offers stronger typing and contracts. For these cases, I generate Apex classes from the WSDL file, which simplifies communication between Salesforce and external services.

12. Explain the use of Custom Metadata and Custom Settings. How do they differ, and when would you use each?

Custom Metadata and Custom Settings are both used to store configuration data, but they differ in their behavior and use cases. Custom Metadata is ideal for storing static configuration data that is consistent across all environments, such as in a managed package. One major advantage of Custom Metadata is that the data can be deployed along with the metadata in a change set or a package, making it easy to maintain across different environments (e.g., sandbox and production).

On the other hand, Custom Settings are more suitable for data that may change based on the environment or user. For example, if I need to store user-specific or organizational preferences, Custom Settings allow me to store this data and access it without consuming SOQL queries. They can also be cached, which improves performance when retrieving configuration data. I use Hierarchy Custom Settings when I need to have different values based on profiles or users, providing a more flexible way to manage environment-specific data.

Here’s an example of retrieving a Custom Metadata value:

TaxRate__mdt taxRate = [SELECT Value__c FROM TaxRate__mdt WHERE Country__c = 'US' LIMIT 1];
System.debug('Tax rate for US: ' + taxRate.Value__c);

On the other hand, Custom Settings are better for data that might vary by user or organization. For instance, I’ve used Hierarchy Custom Settings to store user-specific preferences, like email notification settings or default filters for reports. Custom Settings are accessible without consuming SOQL queries, which makes them more efficient for frequently accessed configuration data.

13. How would you design a solution for managing complex sharing and visibility rules in Salesforce?

When designing a solution for managing complex sharing and visibility rules in Salesforce, I start by fully understanding the business requirements for data access and then translate these into role hierarchies, sharing rules, and manual sharing configurations. I often use role-based hierarchies to control access across different levels of the organization, ensuring that higher-level roles can access records owned by lower-level roles.

For more granular access, I create criteria-based sharing rules to give access to records based on specific fields or conditions, such as account type or region. I also use Apex sharing for cases where sharing rules are too rigid, and custom sharing logic is required. For example, I’ve implemented Apex-managed sharing to ensure that specific users have access to records based on complex conditions that are not easily configured through the UI. This approach ensures both security and flexibility, allowing me to manage complex access requirements while respecting Salesforce’s governor limits on data access.

Here’s an example:

public with sharing class OpportunitySharingService {
    public static void shareOpportunities(List<Opportunity> opportunities) {
        for(Opportunity opp : opportunities) {
            if(opp.Amount > 1000000 && opp.Industry == 'Technology') {
                OpportunityShare shareRecord = new OpportunityShare();
                shareRecord.OpportunityId = opp.Id;
                shareRecord.UserOrGroupId = '005xx0000001abc'; // User Id
                shareRecord.AccessLevel = 'Edit';
                insert shareRecord;
            }
        }
    }
}

This approach ensures that sharing rules meet complex business requirements while staying scalable.

14. What are some ways to optimize SOQL queries to improve performance?

To optimize SOQL queries, my first approach is to minimize the number of fields being queried. I always select only the necessary fields instead of using SELECT *, which reduces the query time and heap size used. I also apply filter conditions to reduce the number of records being queried. For example, using indexed fields in the WHERE clause significantly improves performance, as it allows Salesforce to quickly locate the required records.

Another optimization technique I use is leveraging relationship queries like parent-to-child or child-to-parent queries to avoid making multiple queries for related objects. I also ensure I’m not running queries inside loops, which would cause multiple SOQL queries and might hit governor limits. Instead, I perform bulk queries outside the loop and then process the records in memory, ensuring that my code is both efficient and scalable. Lastly, I use query plan and query optimizer tools in Salesforce to identify areas of improvement in my SOQL queries, ensuring maximum performance for large datasets.

Here’s an example where I avoid querying within a loop:

List<Contact> contacts = [SELECT Id, AccountId FROM Contact WHERE AccountId IN :accountIds];

for(Account acc : accountList) {
    for(Contact con : contacts) {
        if(con.AccountId == acc.Id) {
            // Perform logic on matching contacts
        }
    }
}

By using relationship queries (e.g., child-to-parent or parent-to-child), I ensure that I retrieve related records in a single query, which reduces the number of SOQL calls and improves performance.

15. Can you walk us through a real-time project where you’ve implemented triggers in Salesforce? What challenges did you face and how did you overcome them?

In one of my real-time projects, I implemented a trigger for handling lead conversion processes where custom objects needed to be updated based on the lead’s status. The trigger was designed to update related opportunity and contact records once a lead was converted, ensuring that all associated records reflected the latest information from the converted lead. I used a before update trigger to check the lead’s status and trigger the necessary updates on the related objects.

One of the major challenges I faced was handling trigger recursion. Since multiple records were being updated within the same transaction, the trigger kept firing recursively, which led to governor limit violations. To overcome this, I implemented a static variable in the trigger handler class to ensure that the trigger logic only ran once per transaction. I also encountered performance issues with bulk data processing, which I resolved by processing records in batches and ensuring that DML operations were performed outside the loop, adhering to Salesforce’s bulk processing best practices

To solve this, I implemented a static Boolean flag in the trigger handler to ensure the trigger logic only executed once. Here’s a simplified version of my approach:

public class LeadTriggerHandler {
    private static Boolean isExecuted = false;
    
    public static void handleLeadUpdate(List<Lead> leads) {
        if(isExecuted) return;
        isExecuted = true;
        
        for(Lead lead : leads) {
            Account acc = [SELECT Id, CustomField__c FROM Account WHERE Id = :lead.AccountId];
            acc.CustomField__c = lead.CustomField__c;
            update acc;
        }
    }
}

This approach ensured that trigger recursion was handled effectively, and I was able to complete the project without breaching governor limits.

16. How do you manage governor limits in a multi-tenant environment like Salesforce?

Managing governor limits in Salesforce is critical, especially in a multi-tenant environment where resources are shared across multiple customers. To handle these limits effectively, I ensure that my code is bulk-safe by performing DML operations and SOQL queries in batches rather than processing records individually. I often use lists and maps to group records together, which minimizes the number of SOQL queries and DML statements executed.

For operations involving large data sets, I rely on asynchronous processing techniques like batch Apex, queueable Apex, or future methods to split large jobs into smaller, manageable chunks. Additionally, I use tools like the Governor Limits API to monitor usage and adjust the code to be more efficient. I also follow best practices like avoiding nested loops, limiting the number of queries within loops, and using @future methods to handle operations that don’t require immediate processing.

17. Describe the lifecycle of a transaction in Salesforce when using DML operations.

In Salesforce, the transaction lifecycle begins when a user initiates a DML operation such as insert, update, or delete. Salesforce first checks for validation rules to ensure that the data meets the required criteria. Once the validation checks pass, before triggers are executed, allowing any business logic to modify the record before it is saved to the database. At this point, any field changes made by the before trigger are automatically applied without requiring additional DML operations.

After the before triggers, Salesforce attempts to commit the record to the database. If successful, after triggers are executed, which can be used to update related records or perform additional DML operations. After triggers also allow developers to access the record’s ID, which is not available during the before trigger. Once all triggers are executed, workflow rules, process builder, and approval processes are evaluated. Finally, the transaction is committed, and the after commit events, such as sending notifications, are triggered. If any error occurs during this process, Salesforce rolls back the entire transaction to ensure data integrity.

18. What security measures do you take when writing Apex code, particularly regarding field-level security and CRUD operations?

When writing Apex code, I prioritize security by respecting Salesforce’s field-level security (FLS) and CRUD operations. I never assume that the current user has access to all objects and fields, so I always check for the appropriate permissions before performing DML operations. For example, before querying or updating a field, I use the Schema methods to verify whether the user has the necessary read, create, edit, or delete access to the field or object.

In addition to FLS and CRUD checks, I sanitize all user inputs to prevent SOQL injection and other malicious attacks. I also ensure that my code adheres to security best practices, such as using with sharing keywords in classes to enforce sharing rules, ensuring that users only access data they are authorized to see. By incorporating these measures into my Apex code, I maintain a secure and compliant application environment.

For example, I often use this pattern to check if a user can update a field:

if(Schema.sObjectType.Account.fields.CustomField__c.isUpdateable()) {
    // Proceed with DML
}

This ensures that my code operates securely, only granting access to users who have the appropriate permissions, and prevents security vulnerabilities in my applications.

19. How do you use the @testSetup annotation in test classes, and why is it important?

The @testSetup annotation is an essential tool for creating reusable test data in Salesforce test classes. It allows me to define a method that runs once per test class and creates test data that can be used by all the test methods in the class. This improves the efficiency of the test execution because the data is created once and reused, rather than having to create the same test data in every test method. For example, I often use @testSetup to create common records such as accounts or contacts, which are required across multiple tests.

Another reason @testSetup is important is that it promotes better test class organization and helps avoid duplication of code. By separating the data creation logic from the actual test methods, the test methods focus solely on verifying the functionality being tested. This results in more readable and maintainable test classes.

Here’s an example of @testSetup in action:

@isTest
private class MyTestClass {
    @testSetup
    static void setupData() {
        Account acc = new Account(Name='Test Account');
        insert acc;
        
        Contact con = new Contact(FirstName='John', LastName='Doe', AccountId=acc.Id);
        insert con;
    }
    
    @isTest
    static void testMethod1() {
        // Use account and contact data created in @testSetup
        System.assertEquals('Test Account', [SELECT Name FROM Account LIMIT 1].Name);
    }
}

By reusing the same data across multiple test methods, I ensure that my test classes are more maintainable and efficient.

20. How would you approach debugging a Salesforce issue using tools like the Salesforce Developer Console or logs?

When debugging an issue in Salesforce, my first step is to use the Salesforce Developer Console to analyze the execution logs. The Developer Console allows me to set breakpoints, view debug logs, and monitor performance. I usually start by reproducing the issue while having the debug log levels set to Debug or Finer for detailed insights. This helps me see the sequence of operations and identify any unexpected behaviors or errors in my code.

Additionally, I often leverage the Logs feature to filter out specific types of logs, such as Apex or SOQL logs, which makes it easier to focus on the parts of the code that might be causing the issue. I also utilize the System.debug() statements within my code to output relevant variable values or checkpoints in the process, which can help trace where things might be going wrong.

For example, when facing issues with a trigger, I would include debug statements like this:

trigger AccountTrigger on Account (before insert, before update) {
    for (Account acc : Trigger.new) {
        System.debug('Processing Account: ' + acc.Name);
        // Additional logic...
    }
}

This way, I can see in the logs exactly what accounts are being processed and identify any discrepancies. By combining the insights from the Developer Console and debug logs, I can efficiently troubleshoot and resolve issues within Salesforce.
