Salesforce Interview Questions and Answers

1. Describe the architecture of Salesforce and its key components.

Salesforce architecture is scalable, secure, and customizable, built on a multi-tenant model. Key components include:

• Salesforce Platform (Force.com): Provides infrastructure and services for building applications, including tools for customization and integration.
• Database: Uses a relational database optimized for performance and scalability.
• Application Services: Core services for managing customer relationships, such as Sales Cloud and Service Cloud.
• APIs: Offers various APIs (REST, SOAP, Bulk, Streaming) for integration and custom application development.
• Security and Identity: Features like user authentication, authorization, and data encryption ensure data protection.
• User Interface: Offers a customizable interface, including the modern Lightning Experience.
• AppExchange: A marketplace for third-party applications and components to extend functionality.

2. What is an Apex Trigger and when would you use it?

An Apex Trigger executes before or after specific DML events on a Salesforce record, used for operations like validation or updating related records. Triggers are defined for specific objects and can run before or after events like insert, update, or delete.

Example:

trigger AccountTrigger on Account (before insert, before update) {
    for (Account acc : Trigger.new) {
        if (acc.Industry == 'Technology') {
            acc.Description = 'This is a tech company';
        }
    }
}

3. Write a simple SOQL query to retrieve all accounts with a specific industry.

To retrieve all accounts with a specific industry, use a SOQL query:

SELECT Id, Name FROM Account WHERE Industry = 'Technology'

This query selects accounts where the industry is ‘Technology’.

4. What are Governor Limits in Salesforce?

Governor Limits in Salesforce ensure efficient resource use in its multi-tenant environment, preventing excessive consumption by any single tenant. These limits include restrictions on SOQL queries, DML statements, and CPU time.

Understanding these limits is essential for developing efficient applications. Exceeding them results in runtime exceptions.

5. Write a basic Apex class that includes a method to calculate the sum of two integers.

Apex is used to execute flow and transaction control statements on the Salesforce platform. Below is a basic example of an Apex class that includes a method to calculate the sum of two integers.

8. How do you handle exceptions in Apex?

In Apex, exceptions are handled using try-catch-finally blocks. The try block contains code that might throw an exception, the catch block handles the exception, and the finally block runs regardless of whether an exception was thrown.

Example:

try {
    Account acc = [SELECT Id FROM Account WHERE Name = 'NonExistentAccount'];
} catch (QueryException e) {
    System.debug('QueryException: ' + e.getMessage());
} catch (Exception e) {
    System.debug('Exception: ' + e.getMessage());
} finally {
    System.debug('This is the finally block.');
}

9. Write a SOQL query to find all contacts related to a specific account.
