Salesforce CRM Interview Questions and Answers

1. Explain the concept of Objects in Salesforce and differentiate between Standard and Custom Objects.

Objects in Salesforce function like database tables, storing data specific to an organization. They are categorized into Standard Objects and Custom Objects. Standard Objects, such as Accounts and Contacts, are predefined by Salesforce and address common business needs. Custom Objects are user-created to meet specific business requirements not covered by Standard Objects, allowing for tailored fields and interfaces.

2. What are Validation Rules in Salesforce, and how would you implement one?

Validation rules in Salesforce enforce business rules on data entry, ensuring data quality and consistency. To implement a validation rule, navigate to the object, access the “Validation Rules” section, and create a new rule using Salesforce’s formula language. For example, to prevent an Opportunity’s “Close Date” from being in the past, use the formula CloseDate < TODAY() with an appropriate error message.

3. Describe the use of Triggers in Salesforce and provide an example scenario where a Trigger might be necessary.

Triggers in Salesforce execute custom logic before or after DML events on records, such as insert or update operations. They are useful for automating tasks and ensuring data consistency. For instance, a Trigger can automatically create a Task for an Account owner when a new Contact is added, ensuring follow-up actions.

trigger CreateTaskOnContactInsert on Contact (after insert) {
    List<Task> tasks = new List<Task>();
    
    for (Contact con : Trigger.New) {
        Task t = new Task();
        t.Subject = 'Follow up with new contact';
        t.OwnerId = con.Account.OwnerId;
        t.WhatId = con.AccountId;
        t.WhoId = con.Id;
        tasks.add(t);
    }
    
    if (tasks.size() > 0) {
        insert tasks;
    }
}

4. How do you handle bulk data processing in Apex?

Bulk data processing in Apex is essential for handling large data volumes efficiently while adhering to Salesforce’s governor limits. Apex provides features like collections and batch processing for this purpose. Here’s an example using collections:

public class BulkDataProcessor {
    public void processAccounts(List<Account> accounts) {
        List<Account> accountsToUpdate = new List<Account>();
        
        for (Account acc : accounts) {
            if (acc.Industry == 'Technology') {
                acc.Description = 'Updated for bulk processing';
                accountsToUpdate.add(acc);
            }
        }
        
        if (!accountsToUpdate.isEmpty()) {
            update accountsToUpdate;
        }
    }
}

5. How would you use the Lightning Component Framework to build a custom user interface?

The Lightning Component Framework is a UI framework for developing dynamic web apps. It uses JavaScript on the client side and Apex on the server side. To build a custom UI, create a Lightning Component, use the Lightning Design System for consistent styling, and implement Apex Controllers for server-side logic.

Example:

<!-- myComponent.cmp -->
<aura:component controller="MyApexController">
    <aura:attribute name="myData" type="String"/>
    <lightning:button label="Fetch Data" onclick="{!c.fetchData}"/>
    <lightning:formattedText value="{!v.myData}"/>
</aura:component>

// myComponentController.js
({
    fetchData: function(component, event, helper) {
        var action = component.get("c.getDataFromServer");
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                component.set("v.myData", response.getReturnValue());
            }
        });
        $A.enqueueAction(action);
    }
})

// MyApexController.cls
public with sharing class MyApexController {
    @AuraEnabled
    public static String getDataFromServer() {
        return 'Hello, Salesforce!';
    }
}

6. Describe the role of Governor Limits in Salesforce and how they impact Apex code.

Governor Limits in Salesforce ensure platform stability by preventing excessive resource consumption. These limits apply to operations like SOQL queries, DML statements, and CPU time. To handle these limits, use bulk operations, optimize queries, and avoid complex logic within loops.

7. How do you implement error handling in Apex? Provide an example.

Error handling in Apex uses try-catch-finally blocks. The try block contains code that might throw an exception, the catch block handles exceptions, and the finally block executes regardless of exceptions.

Example:

public class ErrorHandlingExample {
    public void processRecords() {
        try {
            List<Account> accounts = [SELECT Id, Name FROM Account WHERE Name = 'Test'];
            if (accounts.isEmpty()) {
                throw new CustomException('No accounts found with the name Test');
            }
        } catch (CustomException e) {
            System.debug('Custom Exception: ' + e.getMessage());
        } catch (Exception e) {
            System.debug('General Exception: ' + e.getMessage());
        } finally {
            System.debug('Execution completed');
        }
    }
}

public class CustomException extends Exception {}

8. How do you manage data security in Salesforce at the object, field, and record levels?

In Salesforce, data security is managed at the object, field, and record levels. Object-level security is controlled through profiles and permission sets. Field-level security restricts access to specific fields. Record-level security uses organization-wide defaults, role hierarchies, sharing rules, and manual sharing to manage access.

9. Describe the process of deploying changes from a sandbox to production in Salesforce.

Deploying changes from a sandbox to production involves several steps: development and testing in a sandbox, using Change Sets or tools like the Ant Migration Tool for deployment, validating and testing changes, and performing post-deployment steps like updating permissions and communicating changes.

10. How would you integrate Salesforce with an external system using REST API?

Integrating Salesforce with an external system using REST API involves authentication, making API requests, and handling responses. Here’s an example of making a REST API call from Salesforce using Apex:

public class ExternalSystemIntegration {
    public void callExternalAPI() {
        String endpoint = 'https://api.example.com/data';
        
        HttpRequest req = new HttpRequest();
        req.setEndpoint(endpoint);
        req.setMethod('GET');
        req.setHeader('Authorization', 'Bearer ' + getAccessToken());
        
        Http http = new Http();
        HttpResponse res = http.send(req);
        
        if (res.getStatusCode() == 200) {
            String responseBody = res.getBody();
        } else {
            System.debug('Error: ' + res.getStatusCode() + ' ' + res.getStatus());
        }
    }
    
    private String getAccessToken() {
        return 'your_access_token';
    }
}

11. Write an Apex method to call an external REST API and process the response.

To call an external REST API in Salesforce using Apex, use the Http and HttpRequest classes. Create an HTTP request, set headers, send the request, and handle the response.

public class ExternalApiService {
    public void callExternalApi() {
        Http http = new Http();
        HttpRequest request = new HttpRequest();
        request.setEndpoint('https://api.example.com/data');
        request.setMethod('GET');
        request.setHeader('Content-Type', 'application/json');
        
        HttpResponse response = http.send(request);
        
        if (response.getStatusCode() == 200) {
            String responseBody = response.getBody();
            System.debug(responseBody);
        } else {
            System.debug('Error: ' + response.getStatus());
        }
    }
}

12. Explain the concept of Salesforce DX and how it improves the development lifecycle.

Salesforce DX enhances the development lifecycle with features like Scratch Orgs, source-driven development, and CI/CD support. It includes a CLI for automating tasks and a new packaging model for modularizing applications.

13. How do you create effective reports and dashboards in Salesforce to meet business requirements?

Creating effective reports and dashboards in Salesforce involves understanding the data model, selecting the right report type, using filters and groupings, and designing dashboards with components like charts and tables. Leverage dashboard filters and dynamic dashboards for flexibility and personalization.

14. What are some best practices for managing data security in Salesforce?

Managing data security in Salesforce involves best practices like user authentication, role-based access control, field-level security, data encryption, audit trails, data backup, and using the Security Health Check feature.

15. Explain the role of AppExchange in the Salesforce ecosystem.

AppExchange is Salesforce’s marketplace for applications and solutions that enhance Salesforce capabilities. It offers a range of applications, customer reviews, seamless integration, and both free and paid solutions, all meeting security and compliance standards.
