Salesforce Interview Questions and Answers

1. What is Salesforce?

   • Answer: Salesforce is a cloud-based software company that provides customer relationship management (CRM) service and a complementary suite of enterprise applications focused on sales, customer service, marketing automation, analytics, and application development.

2. Explain the different editions of Salesforce.

3. What are Salesforce Clouds? Name a few.

   • Answer: Salesforce offers various clouds, including Sales Cloud, Service Cloud, Marketing Cloud, Commerce Cloud, Community Cloud, Analytics Cloud, App Cloud, and Einstein (AI).

4. What is a Salesforce object? Give examples.

   • Answer: A Salesforce object is a database table that stores information about a specific type of data, such as Accounts, Contacts, Leads, Opportunities, Cases, and custom objects created to meet specific business needs.

5. What are fields in Salesforce?

   • Answer: Fields are columns within a Salesforce object that store specific data points, like Name, Phone, Email, Account ID, etc. They define the attributes of a record.

6. What are records in Salesforce?

   • Answer: Records are individual rows within a Salesforce object representing a specific instance of that object. For example, a record in the Account object represents a single company.

7. Explain the concept of relationships between objects.

   • Answer: Relationships define how different objects are connected. Common relationships include master-detail (one-to-many), lookup (one-to-many or many-to-one), and hierarchical relationships. They ensure data integrity and efficient data retrieval.

8. What is a lookup relationship?

   • Answer: A lookup relationship allows you to link records in one object to records in another object. Unlike master-detail, deleting a related record does not automatically delete the dependent records. It's a weaker relationship.

9. What is a master-detail relationship?

   • Answer: A master-detail relationship creates a strong link between two objects, where the detail object is dependent on the master object. Deleting the master record automatically deletes the related detail records.

    • Answer: Page layouts determine the visual arrangement of fields on record detail pages, ensuring users see the relevant information efficiently and consistently.

11. What is a Salesforce profile?

    • Answer: A Salesforce profile defines a set of permissions and access levels for users, controlling what they can see and do within the Salesforce org.

12. What is a Salesforce role?

    • Answer: A Salesforce role determines a user's hierarchical position within the organization, impacting their access to records based on the reporting structure. Roles grant access to data owned by subordinates.

13. What is the difference between a profile and a role?

    • Answer: Profiles control object and field-level permissions, while roles determine the hierarchical access to records based on reporting structure. Roles are generally applied on top of profiles.

14. What are sharing rules in Salesforce?

    • Answer: Sharing rules define access to records outside of the standard hierarchy established by roles and profiles, allowing more flexible data sharing based on criteria.
