How to answer:
List and briefly describe the main Flow types: Screen, Autolaunched, Record-Triggered, and Schedule-Triggered.
Example answer:
The main types are Screen Flow (user interaction), Autolaunched Flow (background process), Record-Triggered Flow (runs on record changes), and Schedule-Triggered Flow (runs at scheduled times). Each serves distinct automation needs on the platform.
3. How do Record-Triggered Flows differ before-save and after-save?
Why you might get asked this:
Evaluates your understanding of Flow execution order and performance implications, critical for optimization.
How to answer:
Explain the timing of execution and typical use cases for each, highlighting the performance advantage of before-save.
Example answer:
Before-save Flows run before the database commit, primarily for updating the triggering record efficiently. After-save Flows run after saving, enabling actions on related records or external systems, but are less performant for direct record updates.
4. How can Apex be integrated with Salesforce Flows?
Why you might get asked this:
Checks if you know how to combine declarative and programmatic tools for complex logic.
How to answer:
Explain the use of invocable methods in Apex to be called directly from a Flow element.
Example answer:
Apex can be integrated via invocable methods. You write Apex code with logic not feasible in Flow, mark it with @InvocableMethod, and it appears as an action element callable from a Flow.
5. How do you handle bulk processing in Flows?
Why you might get asked this:
Tests your awareness of governor limits and how to design Flows for scale.
How to answer:
Explain the importance of processing collections of records iteratively and performing DML/queries efficiently within loops.
Example answer:
Similar to Apex, bulk processing involves using loops to iterate through collections of records obtained via Get Records and performing operations on the collection as a whole rather than individual records to avoid hitting limits.
6. What are key Salesforce integration patterns?
Why you might get asked this:
Assesses your knowledge of standard approaches for connecting Salesforce with other systems.
How to answer:
List and briefly describe common patterns like Request/Reply, Fire and Forget, Batch Data Synchronization, UI Integration, and Event-driven.

How to answer:
Explain using the Loop element to process items in a collection variable and the need for an Assignment element inside.
Example answer:
You use the Loop element, selecting a collection variable to iterate over. Inside the loop, you perform actions on the current item. Often, results are added to a new collection using an Assignment element for later processing.
12. What is the significance of Assignment Elements in Flows?
Why you might get asked this:
Checks your knowledge of manipulating variable data dynamically during Flow execution.
How to answer:
Explain their role in setting, updating, and manipulating variables and collections.
Example answer:
Assignment elements are critical for setting or changing the values of variables, collection variables, or record variables within a Flow. They are used to store data, update fields before DML, and build or modify collections during loops.
13. How would you design a Flow for automated lead assignment based on region?
Why you might get asked this:
Presents a common business scenario to test your ability to translate requirements into a Flow design.
How to answer:
Outline the steps: trigger, decision based on criteria, and assignment action.
Example answer:
I'd use a Record-Triggered Flow on Lead creation/update. A Decision element checks the Lead's Region field. Based on the region outcome, an Update Records or Assignment element sets the OwnerId field to the appropriate user or queue.
14. What best practices do you follow for naming conventions in Flows?
Why you might get asked this:
Assesses your commitment to maintainability and collaboration.
How to answer:
Emphasize clear, descriptive, and consistent naming for elements, variables, and the Flow itself.

Avoid excessive SOQL queries or DML operations inside loops, implementing overly complex logic that belongs in Apex, using vague variable/element names, and neglecting comprehensive error handling with fault paths.
19. What is a Decision Element in Salesforce Flow?
Why you might get asked this:
Tests your knowledge of basic branching logic within a Flow.
How to answer:
Explain its function as a conditional router, similar to if/else statements.
Example answer:
A Decision element acts like an if/else statement, routing the Flow execution path based on defined conditions or criteria, allowing the Flow to follow different branches depending on the data it processes.
20. How do you manage transactions and rollbacks in a Flow?
Why you might get asked this:
Evaluates your understanding of how database operations are handled and recovering from errors.
How to answer:
Explain that Flows run in a single transaction and how fault paths enable partial handling or full rollback.
Example answer:
By default, a Flow runs in a single transaction. If an unhandled fault occurs, the entire transaction rolls back. Fault paths can catch specific errors or separate operations into subflows/async calls to manage rollbacks more granularly.
21. Explain how Salesforce workflows differ from Process Builder and Flows.
Why you might get asked this:
Tests your historical context and ability to choose the right automation tool.
How to answer:
Describe the evolution and capabilities of each, positioning Flows as the most powerful successor.
Example answer:
Workflows are the oldest, handling simple actions (field updates, email alerts). Process Builder added multi-step criteria and more actions. Flows are the most powerful, supporting complex logic, loops, user interaction, and integration, replacing the others for most new automation.
22. What are Subflows and how do you use them?
Why you might get asked this:
Checks your knowledge of modularizing Flow logic for reusability.
How to answer:
Define Subflows and explain how they promote modular design and reduce duplication.
Example answer:
Subflows are reusable Flows called from other Flows. You use them to break down complex processes into smaller, manageable, and reusable components, improving organization, maintenance, and reducing duplicated logic across multiple Flows.
23. How do you handle errors in a Flow that sends automated emails?
Why you might get asked this:
Presents a common scenario requiring robust error handling.
How to answer:
Describe using fault paths, logging errors, and notifications.
Example answer:
I would use fault connectors on the Send Email element. The fault path could log the error details in a custom object, send a notification to an admin, or attempt an alternative communication method, preventing the entire Flow from failing silently.
24. How would you create a Flow that triggers when a record is deleted?
Why you might get asked this:
Tests your knowledge of Flow limitations and alternative solutions for specific triggers.
How to answer:
Explain that Flows don't natively trigger on delete and suggest Apex triggers or Platform Events as workarounds.
Example answer:
Record-Triggered Flows don't support the 'on delete' trigger. To achieve this, you'd typically use an Apex Trigger on delete to perform the necessary actions or publish a Platform Event that a Flow or another system can subscribe to.
25. What is MuleSoft’s role in Salesforce integration?
Why you might get asked this:
Assesses your understanding of enterprise integration patterns and popular middleware.
How to answer:
Explain MuleSoft as an integration platform acting as middleware for connecting Salesforce to various systems.

MuleSoft acts as an integration platform or middleware that facilitates connecting Salesforce with various external systems using APIs. It provides tools for building robust, scalable, and reusable integration services, streamlining complex data flows.
26. How can you maintain transactional integrity across multiple Salesforce calls?
Why you might get asked this:
Tests your understanding of atomicity and error recovery in distributed operations.
How to answer:
Discuss using Apex transaction control, careful Flow design within limits, or queuing mechanisms.
Example answer:
Within Apex, you use System.savepoint() and rollback() for explicit control. In Flows, operations within a single Flow are transactional. For calls across multiple transactions or systems, consider queuing, state management, or using Apex Batch jobs.
27. Name different ways to trigger a Flow in Salesforce.
Why you might get asked this:
Checks your comprehensive understanding of Flow invocation methods.
How to answer:
List all possible ways: record changes, user action, schedule, Apex, Process Builder.
Example answer:
Flows can be triggered by Record changes (create, update, delete - but delete needs workarounds), user interactions (Screen Flows on buttons, tabs, utility bar), scheduled times, calls from Apex, or by being invoked from Process Builder or other Flows (Subflows).
28. What is the difference between a Lookup and a Master-Detail relationship in Salesforce?
Why you might get asked this:
Tests your foundational data modeling knowledge, essential for any advanced role.
How to answer:
Explain the ownership, requirement, cascade delete, and roll-up summary differences.
Example answer:
Master-Detail is a strong, parent-child relationship where the detail record is "owned" by the master. It's required on the detail, supports roll-up summaries, and has cascade delete. Lookup is a looser relationship, optional, doesn't support roll-ups, and no cascade delete by default.
29. How do you handle Governor Limits in Apex and Flows?
Why you might get asked this:
Crucial test for building scalable and reliable solutions on the multi-tenant platform.
How to answer:
Discuss bulkification, minimizing SOQL/DML in loops, using collections, and asynchronous processing.
Example answer:
I handle limits by bulkifying operations – processing lists/maps of records rather than one by one. This means minimizing SOQL queries and DML statements within loops, using collections effectively, and leveraging asynchronous Apex (Batch, Future, Queueable) or Scheduled/Batch Flows for heavy tasks.
30. What debugging tools are available for Salesforce developers?
