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:
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) {
        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?

  • 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?

  • 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.
