Salesforce Interview Questions and Answers for 7 years experience

1. What is Salesforce and its key features?

   • Answer: Salesforce is a cloud-based software company that provides customer relationship management (CRM) service and a complementary suite of enterprise applications focused on customer service, marketing automation, analytics, and application development. Key features include Sales Cloud, Service Cloud, Marketing Cloud, Sales Force Platform, Community Cloud, and Analytics Cloud. It offers features like contact management, lead management, opportunity management, case management, reporting and analytics, and customization through Apex and Visualforce.

2. Explain the difference between a Lead and a Contact in Salesforce.

   • Answer: A Lead represents a potential customer who hasn't yet become a customer. A Contact represents an individual associated with an Account (a company). Leads are typically qualified and converted into Contacts and Accounts. They have different fields and functionalities to reflect their status in the sales cycle.

3. Describe the different types of Salesforce objects.

   • Answer: Salesforce objects are essentially databases tables storing data. Standard objects are pre-built (e.g., Account, Contact, Opportunity, Case), while custom objects are created to meet specific business needs. They can be related to each other through relationships (e.g., Master-Detail, Lookup, Junction Object).

4. What are the different types of record relationships in Salesforce?

   • Answer: Master-Detail (strong relationship, child record dependent on parent), Lookup (weaker relationship, child record independent), and Junction Object (many-to-many relationship).

5. Explain the concept of sharing rules in Salesforce.

   • Answer: Sharing rules determine data access based on criteria like record ownership, role hierarchy, and other custom criteria. They override organization-wide defaults and can be used to grant access to records beyond standard access controls.

6. What are Apex Triggers and how are they used?

   • Answer: Apex Triggers are server-side code that executes before or after DML operations (insert, update, delete, upsert, undelete) on Salesforce records. They allow for automation of business processes, data validation, and custom logic execution based on record changes.

7. What are Apex classes and how do they differ from Triggers?

   • Answer: Apex classes are reusable blocks of code that encapsulate functionality. Triggers call Apex classes to perform specific actions. Triggers are event-driven, while classes are general-purpose code modules. Classes promote reusability and better code organization.

8. Explain the difference between SOQL and SOSL.

   • Answer: SOQL (Salesforce Object Query Language) is used to query data from Salesforce objects. SOSL (Salesforce Object Search Language) is used to search for data across multiple objects based on keywords.

9. What are governor limits in Salesforce and why are they important?

   • Answer: Governor limits are restrictions on the resources Apex code can consume in a single transaction (e.g., SOQL queries, DML operations, CPU time). They are crucial for maintaining the stability and performance of the Salesforce platform by preventing runaway processes.

10. How do you handle governor limits in your Apex code?

    • Answer: Techniques include batch Apex (for large data volumes), asynchronous Apex (for long-running processes), and careful optimization of queries and DML operations to minimize resource consumption.

11. Explain the use of Visualforce pages.

    • Answer: Visualforce is a markup language used to create custom user interfaces in Salesforce. It allows developers to build dynamic and customized pages that integrate with Salesforce data and functionality, extending the standard Salesforce user interface.

12. What are Lightning Web Components (LWC)? How do they compare to Aura Components?

    • Answer: LWCs are a modern framework for building Salesforce user interfaces using web standards like HTML, JavaScript, and CSS. Compared to Aura components, LWCs are lighter, more performant, and utilize the latest web development technologies. Aura components are the older framework and are gradually being deprecated.
