Highlight the key differences in their syntax, usage, and limitations. Emphasize that SOQL is similar to SQL, while SOSL is more akin to a full-text search engine. A good answer demonstrates when to use each language.
Example answer:
"SOQL, or Salesforce Object Query Language, is used to query records from the Salesforce database, very similar to SQL, but it's specific to Salesforce objects. SOSL, or Salesforce Object Search Language, is used for performing text-based searches across multiple objects. The key difference is that SOQL is used to retrieve records from a single object based on specific criteria, while SOSL is used to search for a specific term across multiple objects. For example, I'd use SOQL to get all contacts with a specific last name, but I'd use SOSL to find a specific keyword across all leads, contacts, and accounts. Knowing when to use each is essential for efficient Salesforce development."
## 3. Explain the MVC Architecture in Salesforce.
Why you might get asked this:
This question explores your understanding of software design principles and how they apply to Salesforce development.

This assesses your ability to develop scalable applications, a crucial skill showcased in accenture salesforce developer interview questions.
How to answer:
Explain the basic principles of the MVC architecture: Model (data layer), View (user interface), and Controller (business logic). Describe how each component is implemented in Salesforce – for example, the Model could be Salesforce objects and fields, the View could be Visualforce pages or Lightning components, and the Controller could be Apex classes. Illustrate how these components interact to handle user requests and display data.
Example answer:
"The MVC architecture is a design pattern that separates an application into three interconnected parts: the Model, the View, and the Controller. In Salesforce, the Model represents the data – typically standard and custom objects, and their fields. The View is the user interface, which could be Visualforce pages, Lightning components, or even the standard Salesforce UI. The Controller is the logic that handles user input and updates the Model, often implemented using Apex classes. For example, when a user edits a record, the Lightning component (View) sends the data to an Apex class (Controller), which updates the Salesforce object (Model). Understanding MVC is crucial for building scalable and maintainable Salesforce applications."
## 4. Difference Between Trigger and Batch Apex.
Why you might get asked this:
This tests your knowledge of different execution contexts in Salesforce and your ability to choose the right tool for the job.

Highlight the key differences in terms of execution context, governor limits, and use cases. State that Triggers are for real-time actions on individual records and Batch Apex is for processing large data sets.
Example answer:
"Triggers are Apex code that executes before or after specific database events occur, like inserting, updating, or deleting records. They operate in real-time, within the same transaction that initiated the event. Batch Apex, on the other hand, is used for processing large volumes of data asynchronously. It operates outside the context of a user transaction and is designed to avoid hitting governor limits when dealing with a large number of records. For example, I'd use a Trigger to update a related record whenever a new lead is created, but I'd use Batch Apex to update a million account records overnight. Choosing the right tool depends on the scale of the operation and whether it needs to happen in real-time."
## 5. Implementing Security in a Salesforce Application.

Explain how to use these features to restrict access to data based on user roles and permissions. Mention the importance of using "with sharing" or "without sharing" keywords in Apex classes to enforce or bypass sharing rules, respectively. Emphasize a layered approach.
Example answer:
"Implementing security in Salesforce involves a multi-layered approach. First, we have organization-wide defaults, which set the baseline access for all users. Then, we use role-based and profile-based access control to grant different levels of access based on a user's role or profile. Field-level security allows us to control access to specific fields, and sharing rules allow us to grant access to records based on specific criteria. In Apex, we use the 'with sharing' keyword to enforce sharing rules and the 'without sharing' keyword to bypass them when necessary. For example, a sales manager might have access to all opportunities in their region, while a sales rep only has access to their own opportunities. Combining these techniques ensures a secure Salesforce environment."

How to answer:
Explain that the 'with sharing' keyword enforces the sharing rules of the current user, while the 'without sharing' keyword bypasses these rules. Describe when you would use each keyword. Provide examples of scenarios where you would use each keyword to control data access.
Example answer:
"The 'with sharing' keyword in Apex enforces the sharing rules of the current user, ensuring that the code only has access to the data that the user is allowed to see. The 'without sharing' keyword, on the other hand, bypasses these rules, allowing the code to access all data regardless of the user's permissions. I would use 'with sharing' when I want to ensure that the code respects the user's security context, such as in a Visualforce controller. I would use 'without sharing' when I need to perform system-level operations, such as data migration or integration with an external system. It's important to use these keywords carefully to control data access and prevent security vulnerabilities."
## 24. What are Future Methods in Salesforce?
Why you might get asked this:
This question assesses your understanding of asynchronous processing in Salesforce and your ability to offload long-running operations to the background. Future methods allow you to execute code asynchronously, which can improve the performance of your application and avoid governor limits. Asynchronous processing is important when answering accenture salesforce developer interview questions.
How to answer:
Explain that future methods are asynchronous methods that run in the background, allowing for efficient execution of time-consuming operations without blocking the main execution thread. Describe the limitations of future methods, such as the inability to call them from triggers or other future methods. Provide examples of scenarios where you would use future methods.
Example answer:
"Future methods are asynchronous methods that run in the background, allowing you to execute long-running operations without blocking the main execution thread. They're useful for tasks that don't need to be executed immediately, such as sending email notifications or updating external systems. However, future methods have some limitations – for example, you can't call them from triggers or other future methods. I would use a future method to send an email notification to a customer after a case is closed or to update an external system with data from Salesforce."
