Salesforce Developer (Apex) Interview Questions
1. What are the different types of triggers in Apex, and how do you decide when to use before or after triggers?
Apex triggers are classified into before and after triggers based on when they are executed relative to the DML operation. Before triggers are used when you want to modify the data before it is saved to the database, such as validating or updating fields on a record. After triggers are used when you need to perform actions that require the data to be committed to the database, such as creating related records or sending notifications. The choice depends on whether your logic needs to execute before or after the database operation.
2. Explain the difference between SOQL and SOSL in Salesforce, and when would you use each?
SOQL (Salesforce Object Query Language) is used to fetch records from a single object or multiple related objects. It is suitable when you need to retrieve specific fields or use conditions to filter records. SOSL (Salesforce Object Search Language) is used to perform text-based searches across multiple objects and fields simultaneously. It is ideal for full-text searches, such as finding records where a keyword is present. Use SOQL for precise, structured queries and SOSL for broader, keyword-based searches.
3. How does Apex handle bulk data operations, and what is the significance of bulkification in trigger development?
Apex is designed to handle bulk operations by processing records in batches, which is why it is important to write bulkified code that can handle multiple records at once. Bulkification ensures that your triggers or methods process all incoming records efficiently, rather than executing one operation per record. This is crucial to stay within Salesforce Governor Limits, such as limits on DML statements or SOQL queries. For example, using collections like lists or maps instead of operating on single records helps optimize performance and avoid runtime errors.
4. What is a Governor Limit in Salesforce, and how can a developer optimize Apex code to avoid exceeding these limits?
Governor Limits are Salesforce-enforced constraints to ensure fair resource usage in a multi-tenant environment. These include limits on SOQL queries, DML operations, heap size, and execution time. To avoid exceeding these limits, developers should follow best practices like using bulkified code, querying only required fields, avoiding nested SOQL queries or loops, and using collections to handle data in bulk. Tools like debug logs and the Apex Execution Governor Limits in Developer Console can help monitor and optimize code performance.
5. What are the best practices for writing test classes in Salesforce to ensure high code coverage?
To ensure high code coverage, developers should follow these best practices:
Verify outcomes with System.assert() to ensure your code behaves as expected.
Following these practices ensures robust, maintainable code and compliance with Salesforce’s 75% minimum code coverage requirement.
Write test methods for every public and global method in your classes.
Use meaningful test data with Test.startTest() and Test.stopTest() to isolate test execution.
Cover both positive and negative test scenarios, including edge cases and bulk operations.
Use mock data and avoid dependency on actual org data by using Test.setMock() or custom objects.
6. How do you implement custom exceptions in Apex, and why would you use them?
Custom exceptions in Apex are user-defined exception classes that allow developers to handle specific errors in their code. You create a custom exception by extending the Exception class. For example:
public class CustomException extends Exception {}Custom exceptions are useful when you need to handle specific scenarios, such as invalid input or business logic violations, and provide meaningful error messages. They help in debugging and ensure that errors are handled gracefully within your application.
7. What is the difference between a standard controller and a custom controller in Visualforce, and how do they interact with Apex?
A standard controller is a built-in Visualforce controller provided by Salesforce that allows basic CRUD operations on a single object. For example, you can use standardController="Account" to access Account records without writing Apex code. A custom controller, on the other hand, is an Apex class that developers create to handle custom logic or operations beyond what standard controllers provide. Custom controllers give you full control over the page’s behavior and can interact with multiple objects or perform complex actions.
8. How can you use the @future annotation in Apex, and what are its limitations?
The @future annotation is used in Apex to define methods that execute asynchronously, typically for long-running operations or when performing callouts to external systems. For example:
@future(callout=true)
public static void calloutMethod() {
// Perform callout
}Limitations of @future methods include:
- They cannot return values.
- They must be static.
- A single Apex transaction can enqueue a maximum of 50 future methods.
- Future methods cannot call another future method.
9. What is the purpose of the Database.SaveResult class in Apex, and how is it used in DML operations?
The Database.SaveResult class is used to capture the outcome of DML operations performed using the Database.insert() or Database.update() methods. These methods allow partial success in bulk operations by continuing to process records even if some fail. The SaveResult object provides information such as whether the operation was successful (isSuccess()), any error messages (getErrors()), and the record ID of the processed record. This is useful for handling errors gracefully in bulk operations.
10. Explain the concept of Apex Batch Processing, and how does it differ from Queueable Apex?
Apex Batch Processing is a framework used to handle large volumes of data by processing records in smaller chunks (batches). It implements the Database.Batchable interface and consists of three methods: start, execute, and finish. Batch processing is ideal for handling millions of records efficiently while adhering to Salesforce Governor Limits.
Queueable Apex, on the other hand, is designed for simpler asynchronous operations and is more flexible than @future. It allows chaining of jobs and supports complex object types. However, it processes records sequentially rather than in batches, making it better suited for smaller-scale tasks.
Salesforce Javascript Interview Questions
1. What is Lightning Web Components (LWC), and how does it use JavaScript in Salesforce?
Lightning Web Components (LWC) is a modern framework introduced by Salesforce to build web applications. It uses standard JavaScript, HTML, and CSS, adhering to web standards. JavaScript in LWC is used for handling component logic, event handling, data manipulation, and integrating with Salesforce’s server-side features like Apex. By leveraging ES6+ features, LWC ensures better performance and a modern development experience compared to Aura components.
2. How do you handle events in Lightning Web Components?
Event handling in LWC is managed using JavaScript’s event system. Components communicate using custom events. A child component fires an event using CustomEvent, and a parent component listens to it using event listeners in HTML. For example, a child component might fire an event like this:
<c-child-component oncustomevent={handleEvent}></c-child-component>The corresponding JavaScript method in the parent handles the event:
handleEvent(event) {
console.log(event.detail.value);
}3. What are decorators in LWC, and how do you use them with JavaScript?
Decorators in LWC are annotations used to enhance the behavior of properties and methods in a component. Salesforce provides three main decorators:
- @api: Makes a property or method public, allowing it to be accessed by parent components.
- @track: Tracks changes to a property’s value and automatically re-renders the component.
- @wire: Connects a component to Salesforce data using a wire adapter.
For example, using @api to expose a property to a parent component:
import { LightningElement, api } from 'lwc';
export default class MyComponent extends LightningElement {
@api recordId; // Accessible by parent components
}4. How do you perform server-side communication in LWC using JavaScript?
LWC uses JavaScript to communicate with server-side Apex methods through @wire or imperative Apex calls. With @wire, the framework automatically handles data binding:
import { LightningElement, wire } from 'lwc';
import getRecords from '@salesforce/apex/MyApexClass.getRecords';
export default class MyComponent extends LightningElement {
@wire(getRecords) records;
}For imperative calls, JavaScript allows developers to call Apex methods dynamically
import getRecords from '@salesforce/apex/MyApexClass.getRecords';
connectedCallback() {
getRecords()
.then(result => {
this.records = result;
})
.catch(error => {
console.error(error);
});
}
5. What are Promises in JavaScript, and how are they used in Salesforce LWC?
A Promise in JavaScript is an object representing the eventual completion or failure of an asynchronous operation. In LWC, Promises are often used to handle asynchronous Apex calls or fetch operations. A Promise has three states: pending, resolved, or rejected.
Example usage of a Promise in LWC:
import fetchData from '@salesforce/apex/MyApexClass.fetchData';
fetchData()
.then(result => {
console.log('Data fetched:', result); // Handle resolved state
})
.catch(error => {
console.error('Error occurred:', error); // Handle rejected state
});Promises help streamline asynchronous workflows, ensuring better readability and error handling in LWC components.
6. How do you use JavaScript ES6 modules in Lightning Web Components?
JavaScript ES6 modules are fundamental in Lightning Web Components (LWC). LWC organizes JavaScript code into separate modules, with each component being a module. You can import and export functions, variables, or classes between modules. For example:
Exporting a function in utility.js:
export function formatDate(date) {
return new Date(date).toLocaleDateString();
}Importing and using it in myComponent.js:
import { formatDate } from './utility';
console.log(formatDate('2023-01-01'));Modules ensure better organization, reusability, and maintainability of code in LWC.
7. What is two-way data binding in LWC, and how is it achieved using JavaScript?
LWC uses one-way data binding by default, but two-way data binding can be simulated using event handlers. For example, binding input values to a property:
HTML:
<lightning-input type="text" value={name} onchange={handleChange}></lightning-input>Here, the onchange event updates the name property in real time, achieving a two-way binding effect.
8. How does JavaScript handle promises with async/await, and how is it applied in LWC?
Async/await is a modern syntax for handling asynchronous operations with Promises. It simplifies code readability compared to .then() and .catch() chaining. In LWC, you can use async/await to call Apex imperatively:
Example:
import fetchData from '@salesforce/apex/MyApexClass.fetchData';
export default class MyComponent extends LightningElement {
async fetchDataFromApex() {
try {
const result = await fetchData();
console.log('Fetched Data:', result);
} catch (error) {
console.error('Error fetching data:', error);
}
}
}Using async/await makes asynchronous code look more synchronous and easier to debug.
9. What is the use of Proxies in JavaScript, and how does LWC leverage them?
A Proxy in JavaScript is an object that allows developers to define custom behavior for fundamental operations like property access or assignment. In LWC, Salesforce uses Proxies internally to track changes in reactive properties for automatic UI updates. For example, the @track decorator wraps properties in a Proxy to detect mutations and trigger re-renders.
Custom example:
const handler = {
get: (obj, prop) => {
return prop in obj ? obj[prop] : 'Property not found';
}
};
const proxyObj = new Proxy({ name: 'John' }, handler);
console.log(proxyObj.name); // Outputs: John
console.log(proxyObj.age); // Outputs: Property not foundProxies are a key part of reactivity in LWC.
10. How do you optimize JavaScript performance in Lightning Web Components?
To optimize JavaScript performance in LWC:
- Debounce Event Handlers: Reduce unnecessary re-renders by debouncing input events.
- Lazy Loading: Load non-critical resources or components only when needed.
- Use @track and @wire Wisely: Minimize unnecessary reactivity and avoid overloading wire methods.
- Avoid Complex Loops: Use efficient algorithms and avoid deep nesting in loops or conditions.
- Cache Data: Use properties to cache frequently accessed data, reducing redundant computations.
Following these practices ensures better responsiveness and user experience in LWC components.
