What Does a Salesforce Developer Do?

A Salesforce Developer is responsible for creating, building, and personalizing applications within the Salesforce platform. They work with tools like Apex, Visualforce, and Lightning Web Components (LWC) to create solutions that meet business needs.

In simple words, they make Salesforce smarter and more efficient for organizations.

Salesforce Developer Interview Questions for Freshers

Here are some commonly asked questions if you are just starting your Salesforce career:

1. What is Salesforce?
   Salesforce is a cloud-based CRM platform that helps businesses manage customer relationships, sales, marketing, and analytics all in one place.

2. What are the different types of Salesforce clouds?
   Sales Cloud, Service Cloud, Marketing Cloud, Commerce Cloud, and Experience Cloud.

3. What is an Object in Salesforce?
   An object is a database table that stores information. There are two types: Standard Objects (like Account, Contact, Lead) and Custom Objects (created by users).

4. What is a Trigger in Salesforce?
   A Trigger is an Apex code that executes automatically before or after data modification operations like insert, update, or delete.

5. What is a Workflow in Salesforce?
   A workflow automates standard internal procedures, such as sending email alerts or updating fields when specific conditions are met.

6. What is the difference between a Role and a Profile?

• Profile controls what a user can do (permissions).

• Role controls what data a user can see (data visibility).

7. What are Lightning Web Components (LWC)?
   LWC is a modern web-based framework used to build fast and dynamic user interfaces in Salesforce using HTML, JavaScript, and CSS.

8. What is SOQL in Salesforce?
   SOQL (Salesforce Object Query Language) is used to retrieve data from Salesforce objects, similar to SQL in databases.

9. What is a Governor Limit in Salesforce?
   Salesforce uses governor limits to ensure efficient use of shared resources. For example, there’s a limit to how many SOQL queries you can run in a single transaction.

10. How do you deploy code in Salesforce?
    You can deploy code using Change Sets, Salesforce CLI, or ANT Migration Tool.

Salesforce Developer Interview Questions for Experienced (2 to 5 Years)

If you have some hands-on experience, interviewers will test your technical depth and understanding of real-time challenges.

1. What is the difference between a Trigger and a Process Builder?
   A Trigger executes Apex code, while a Process Builder is a point-and-click tool used for automation without coding.

2. Explain the concept of Governor Limits in detail.
   Governor Limits are restrictions that ensure resources are used efficiently in a multi-tenant environment. For instance, there’s a limit of 100 SOQL queries per transaction.

3. What are Batch Apex and Queueable Apex?

• Batch Apex: Used for processing large amounts of data in chunks.

• Queueable Apex: Used to run jobs asynchronously with more flexibility than future methods.

4. What is the difference between “before” and “after” triggers?

• Before Triggers: Used to validate or modify data before saving it.

• After Triggers: Used when records are already saved to the database, often for updates in related records.

5. What are Test Classes in Salesforce?
   Test Classes ensure code quality and help validate that your logic works correctly. You must have at least 75% test coverage to deploy Apex code.

6. How do you handle errors in Apex?
   By using try-catch blocks to catch exceptions and write error-handling logic to prevent system crashes.

7. What is a Wrapper Class?
   A Wrapper Class is a custom data structure that combines multiple fields or objects into one logical unit for easier processing.

8. Explain Apex Triggers’ best practices.

• Avoid SOQL or DML statements inside loops.

• Use one Trigger per object.

• Use context variables like Trigger.isInsert or Trigger.isUpdate.

9. What are Lightning Components?
   Lightning Components are building blocks of Salesforce’s modern UI that help developers create dynamic web applications quickly.

10. How can you improve performance in Salesforce development?
    By using selective queries, indexing fields, pulpifying code, and using asynchronous processing when needed.

Scenario-Based Salesforce Developer Interview Questions

2. Scenario:

   Answer: Write an after update trigger on the Account object to loop through related contacts and update them.

3. Scenario:
   A user complains they can’t see a record even though they have permission. What will you check?
   Answer: Check Role Hierarchy, Sharing Rules, Organization-Wide Defaults (OWD), and Profile settings.

4. Scenario:
   How would you handle large data volumes when processing records?
   Answer: Use Batch Apex or Queueable Apex to process records in manageable chunks.
