Below, you’ll find 25 interview questions and answers that will help you assess applicants’ Salesforce Flow skills and knowledge. You can use them for all Salesforce Flow roles, from junior developers to Salesforce architects.

1. What is Salesforce Flow?

Salesforce Flow is a powerful automation tool that allows users to create applications to collect, manipulate, and update data in a visual interface, enabling users to automate complex business processes without needing extensive coding skills.

2. What are the different types of Flow in Salesforce?

There are mainly two types of Flow in Salesforce:

• Screen Flows: Used for guiding users through a series of screens for data input.
• Auto-launched Flows: These are initiated without user interaction and can be triggered by processes, Apex, or other system events.

3. How do you implement a decision element in a Flow?

To implement a decision element in a Flow:

1. Drag the "Decision" element onto the Flow canvas.
2. Set the outcomes based on specific conditions.
3. Connect the decision element to other elements based on the selected outcome.

4. Can you explain the difference between Flow and Process Builder?

• Flow: More powerful, supports complex logic, loops, and can handle bulk records.
• Process Builder: Easier to use for simple processes, best for straightforward automation without extensive logic.

5. What is the purpose of the 'Get Records' element in a Flow?

The 'Get Records' element is used to retrieve records from Salesforce based on specified criteria, allowing the Flow to work with data dynamically.

6. How can you debug a Flow?

You can debug a Flow by:

• Using the Flow Debugger feature, which allows you to run the Flow step-by-step.
• Checking the debug logs for error messages or unexpected behavior.

7. What are the limits on Flow execution?

Flow execution limits include:

• Governor limits for SOQL and DML operations.
• A maximum of 2,000 records in a collection variable.
• The runtime limit is typically 5 minutes for flows executed synchronously.

8. How can you handle errors in Flow?

Errors can be handled using:

• Fault paths: You can define paths for error handling if any element fails.
• Try-Catch mechanism can be simulated by using a combination of Fault paths and decision elements.

9. What is the role of the 'Update Records' element in a Flow?

The 'Update Records' element is used to modify existing records in Salesforce based on data collected earlier in the Flow.

10. How do you call a Flow from a button click?

To call a Flow from a button click:

1. Create a custom button.
2. Set the button's URL to include the Flow's API name, e.g., /flow/Your_Flow_Name.
3. Add any necessary parameters to the URL.

11. What are Flow variables?

Flow variables are used to store information in Flow. They can hold values temporarily and can be of several types such as:

• Text
• Number
• Boolean
• Record (for holding a specific Salesforce object)

12. Can you use Flow to create records? If so, how?

Yes, you can use Flow to create records using the Create Records element by specifying the object type and the fields you want to populate.

13. What is a collection variable in Salesforce Flow?

A collection variable is a variable type used to store multiple records of the same object, allowing you to process them in loops or pass them into an update or delete action.

14. Explain the difference between a loop and a collection in Flow.

• Loop: Iterates over each item in a collection variable one by one.
• Collection: A group of records that can be processed together in bulk.

15. How do you schedule a Flow to run at specific intervals?

You can schedule a Flow using Scheduled Flows, which can be configured to run at certain times or intervals, similar to a cron job.

16. How can you pass data between flows?

Data can be passed between flows using input and output variables, allowing one Flow to provide data to another flow when started.

17. What are flow templates and when would you use them?

Flow templates are pre-built Flow configurations that can be reused. They simplify Flow creation by providing a standard structure for common processes.

18. How can you optimize a Flow for performance?

Performance can be optimized by:

• Reducing the number of elements and decisions.
• Minimizing the number of record lookups.
• Using bulk processing where applicable.

19. Explain flows vs. workflows.

• Flows: More complex, can handle multiple objects, loops, and unsynchronized execution.
• Workflows: Limited to single-object tasks, less flexible and cannot handle complex logic.

20. How do you make a Flow run in System Context?

You can make a Flow run in System Context by using Autolaunched Flows, which can be invoked through Apex, allowing them to bypass sharing rules.

21. What are some common use cases for Salesforce Flow?

Common use cases include:

• Automating business processes.
• Collecting data through user interfaces.
• Integrating with external systems.
• Managing approvals and notifications.

22. Can Flows invoke Apex code? If so, how?

Yes, Flows can invoke Apex code through Apex Actions, allowing you to execute custom logic as part of the Flow process.

23. What is a "Flow Each Element" option?

The "Flow Each Element" option allows you to loop over each item in a collection variable and perform operations individually on each item.

24. How do you manage Flow versions?

Flow versions can be managed through the Flow builder interface, where you can activate or deactivate versions, allowing for staged deployments and rollbacks.

25. What are the governor limits you need to watch for in Flow?

Key governor limits for Flow include:

• Limits on SOQL and DML statements.
• Maximum execution time (typically 5 minutes).
• Concurrent Flow execution limits.
