100 Salesforce Interview Questions and Answers

  1. What are the different types of Salesforce licenses?

    • Answer: Salesforce offers various licenses categorized by user roles and functionalities. These include Sales Cloud licenses (Salesforce Sales Cloud Essentials, Sales Cloud, Sales Cloud Unlimited), Service Cloud licenses (Service Cloud Essentials, Service Cloud), and others like Marketing Cloud, Community Cloud, and Platform licenses (Developer Edition, Enterprise Edition, Unlimited Edition). Each license type grants access to specific features and functionalities, with pricing varying accordingly. The choice depends on the user's role and the organization's needs.

  2. Explain the difference between a trigger and a workflow rule.

    • Answer: Both triggers and workflow rules automate processes in Salesforce, but they differ significantly. Workflow rules operate on individual records and are triggered by record creation or updates, performing actions like field updates, email alerts, or outbound messages. Triggers, on the other hand, are Apex code that execute before or after DML operations (create, read, update, delete) on records, providing more flexibility and control over data manipulation. Triggers can perform complex logic and operations unavailable to workflow rules, but require Apex coding expertise.

  3. What is the purpose of a governor limit in Salesforce?

    • Answer: Governor limits are restrictions imposed by Salesforce to ensure system stability and prevent any single transaction or user from monopolizing resources. These limits encompass various aspects, including the number of SOQL queries, DML operations, Apex CPU time, heap size, and more. Exceeding these limits results in errors and prevents the completion of the process, safeguarding the platform's performance for all users.

  4. Describe your experience with Salesforce data migration.

    • Answer: [This requires a personalized answer based on your experience. Include details about the methods you've used (Data Loader, Apex Data Loader, third-party tools), the size and complexity of the data sets, any challenges encountered, and the strategies employed to ensure data integrity and accuracy. For example: "I have extensive experience migrating data to Salesforce using Data Loader and Apex Data Loader. In one project, we migrated over 10 million records from a legacy system, implementing data cleansing and transformation processes to ensure data quality. We faced challenges with data inconsistencies and duplicates, which we addressed using deduplication tools and custom Apex code."]

  5. Explain the different types of sharing rules in Salesforce.

    • Answer: Salesforce sharing rules control access to records based on criteria defined by the administrator. There are several types: Ownership-based sharing gives access based on record owner, while hierarchical sharing grants access based on the user's position in the organization's hierarchy (e.g., manager-subordinate). Criteria-based sharing allows granting access based on specific record field values, and manual sharing allows individual records to be shared with specific users or groups. These sharing rules are crucial for defining data security and access controls within the organization.

  6. How do you handle Salesforce performance issues?

    • Answer: [This answer should be tailored to your experience. Discuss your approach to identifying bottlenecks using tools like the Salesforce Debugger, Developer Console, and monitoring tools. Explain how you optimize queries (using indexes, avoiding SELECT *), minimize SOQL queries, and utilize bulk APIs for efficient data processing. Describe your troubleshooting process and how you prioritize resolving performance issues based on impact.]

  7. What are the different types of relationships in Salesforce?

    • Answer: Salesforce supports several types of relationships between objects: Master-detail relationships, where the detail record's existence depends on the master record; lookup relationships, where the detail record can exist independently of the master record; and many-to-many relationships, which require a junction object to connect two objects. The choice depends on the business requirements and data dependencies.

  8. Explain your experience with Salesforce Apex.

    • Answer: [This needs a personalized answer, describing your experience with Apex programming, including coding best practices, handling governor limits, writing efficient and maintainable code, and using Apex features like triggers, classes, and controllers. Mention specific projects where you used Apex and the problems you solved.]

  9. What is the difference between a Visualforce page and a Lightning component?

    • Answer: Visualforce pages are custom pages built using a markup language similar to HTML, primarily used in Salesforce Classic. Lightning components, however, are built using a component-based framework that promotes reusability and responsiveness, better suited for the Lightning Experience. Lightning components offer better performance, improved user experience, and a more modular approach to development.
