Common Salesforce Flow Interview Questions and Answers
- What is Salesforce Flow?
- Salesforce Flow is a powerful automation tool within Salesforce that allows users to create complex workflows to automate business processes without writing any code.
- Can you explain the different types of Flows available in Salesforce?
- Salesforce offers various types of Flows including Screen Flows, Autolaunched Flows, Record-Triggered Flows, Schedule-Triggered Flows, and Platform Event-Triggered Flows.
- What are the main components of a Flow?
- The main components of a Flow are Elements, Resources, and Connectors. Elements perform actions, Resources store data, and Connectors define the path of execution.
- How do you create a decision element in Flow?
- A decision element is created by defining criteria that determine which path the Flow should take. It’s similar to an “if-else” statement in programming.
- Can Flows call Apex classes?
- Yes, Flows can call Apex classes using the “Apex” action element, allowing for the execution of complex logic that may not be possible directly within the Flow.
- Here’s a sample code snippet that demonstrates how to call an Apex class from a Salesforce Flow using the
@InvocableMethod
annotation:

- Yes, Flows can call Apex classes using the “Apex” action element, allowing for the execution of complex logic that may not be possible directly within the Flow.
public class AccountActionController { @InvocableMethod(label='Get Account Names' description='Returns the list of account names') public static List<String> getAccountNames(List<ID> ids) { List<String> accountNames = new List<String>(); List<Account> accounts = [SELECT Name FROM Account WHERE Id IN :ids]; for (Account account : accounts) { accountNames.add(account.Name); } return accountNames; } }
In this example, the AccountActionController class has a method getAccountNames
that is marked as invocable. This method takes a list of IDs and returns a list of account names. You can call this method from a Flow by creating an Apex action that references this method.
- What are some common use cases for Salesforce Flows?
- Common use cases include lead assignment, data cleanup, customer onboarding, and more.
- How can you schedule a Flow to run at specific intervals?
- You can use Schedule-Triggered Flows to run at defined intervals, such as daily or weekly.
- What is a Screen Flow?
- A Screen Flow is a type of Flow that interacts with the user through screens to collect data or provide information.
- What is a Record-Triggered Flow?
- A Record-Triggered Flow automatically runs when a record is created, updated, or deleted.
- How do you debug a Flow?
- Salesforce provides a debug option within the Flow Builder that allows you to test and troubleshoot your Flows.
- What are Flow Resources?
- Flow Resources are variables, constants, formulas, and collections that store data within a Flow.
- Can you use SOQL queries in Flows?
- Yes, you can use the “Get Records” element to perform SOQL queries within Flows.
- What are the limitations of Salesforce Flow?
- Limitations include a maximum number of elements, SOQL queries, DML operations, and loop iterations.
- How do you handle errors in Flows?
- You can use fault connectors and error handling elements to manage exceptions in Flows.
- Can Flows integrate with external systems?
- Yes, Flows can integrate with external systems using actions like HTTP requests or Salesforce Connect.
- What is a Loop element in Flow?
- A Loop element iterates over a collection of records or values within a Flow.
- How do you optimize the performance of a Flow?
- To optimize performance, minimize SOQL queries, use filters, and avoid unnecessary loops.
- What is the difference between a Flow and Process Builder?
- Flows are more versatile and can handle complex logic, while Process Builder is better suited for simpler, criteria-based automation.
- Can you create custom screens in Flows?
- Yes, you can create custom screens with various input and display components in Screen Flows.
- How do you pass data between Flow elements?
- Data is passed between elements using Flow Resources like variables and collections.
- What is a Subflow?
- A Subflow is a reusable Flow that can be invoked by another Flow.
- Can you use Flow to create or update records in bulk?
- Yes, Flows can create or update records in bulk using the “Create Records” and “Update Records” elements.
- How do you ensure a Flow is bulk-safe?
- To ensure bulk-safety, design Flows that can handle multiple records efficiently and avoid hitting governor limits.
- What is a Collection Variable in Flow?
- A Collection Variable is a type of variable that holds multiple values or records.
- Can you use Flow to send emails?
- Yes, Flows can send emails using the “Send Email” action element.
- What is a Pause element in Flow?
- A Pause element temporarily suspends the execution of a Flow until a specified event occurs.
- How do you use Flow to guide users through a process?
- Screen Flows can be designed with multiple screens to guide users through a step-by-step process.
- What is a Platform Event-Triggered Flow?
- This type of Flow is triggered by the occurrence of a platform event message.
- Can you use Flow to delete records?
- Yes, Flows can delete records using the “Delete Records” element.
- What is the difference between a Constant and a Variable in Flow?
- A Constant holds a fixed value, while a Variable’s value can change during the Flow’s execution.
- How do you validate user input in Screen Flows?
- You can use validation rules or conditional visibility to ensure user input meets certain criteria.
- What is a Flow Template?
- A Flow Template is a pre-built Flow that can be customized and deployed in your org.
- Can you use Flow to automate data migration?
- While not typically used for large-scale data migration, Flows can automate the movement of small sets of data.
- How do you handle bulk data processing in Flows?
- Use collection variables and loops to process data in bulk, and be mindful of governor limits.
- What is a Flow Action?
- A Flow Action is an operation that can be performed within a Flow, such as creating a record or sending an email.
- Can you use Flow to manage approval processes?
- Yes, Flows can be configured to handle approval processes by routing records and managing approvals.
- How do you test a Flow?
- Flows can be tested using the debug feature or by creating test scenarios in a sandbox environment.
- What is a Flow Orchestrator?
- Flow Orchestrator is a tool that allows you to design complex, multi-user workflows with Flows.
- Can you use Flow to update related records?
- Yes, Flows can update related records using the “Update Records” element and specifying the relationship.
- How do you use Flow to enforce business rules?
- Flows can enforce business rules by evaluating criteria and performing actions based on those evaluations.
- What is a Flow Element?
- A Flow Element is a building block of a Flow that performs a specific function, like a decision or an action.

- A Flow Trigger is an event that initiates the execution of a Flow, such as a record update or a scheduled time.
- Can you use Flow to integrate with APIs?
- Yes, Flows can integrate with APIs using HTTP request elements to send and receive data.
- What is a Flow Loop Counter?
- A Flow Loop Counter is a system variable that tracks the number of iterations in a loop.
- How do you use Flow to handle exceptions?
- Flows can handle exceptions using fault connectors and error handling elements to manage unexpected outcomes.
