Salesforce Flow Interview Question & Answers

Solid expertise in Salesforce Flows stands as one of the highly sought-after skills during job interviews.

Here are 15 commonly asked questions in the Interviews:

Question 1: Explain the concept of transaction with respect to Salesforce Flow.

Answer - In Salesforce, a transaction refers to a bunch of actions carried out as one unit. Governor limits are set to ensure a fair share of resources among organizations. How a transaction kicks off depends on how the Flow is spread out.

Question 2: What are Platform event trigger Flows in Salesforce?

Answer - Platform Events are part of Event-Driven Architecture, allowing different apps—whether inside or outside Salesforce—to communicate. They work by using a publish/subscribe system and team up with a message bus to manage incoming events.

Using platform event-triggered flows consolidates all your automation in a single location. It allows users to activate a Flow whenever they receive a platform event message.

Question 3: What are the different ways to capture error messages when working with Salesforce Flows?

Answer - Following are the ways to capture error messages:

• Using fault connectors
• Creating a Case
• Post to chatter
• Sending an email

Question 4: How to call a Screen Flow from Lightning Web Component?

Answer - This functionality is supported by Winter'23 and later releases

Steps for calling a Screen Flow from LWC:

• Create a new Screen Flow or use an already created Screen Flow.
• Create a LWC Component
• Pass the Screen Flow name in the <lightning-flow> tag.

Question 5: What is the Order of execution of Salesforce Flows?

Answer - In the sequence of execution, before-save record-triggered flows take precedence, followed by before-save triggers, after-save triggers and finally, after-save record-triggered flows.

Question 6: What is Subflow in Salesforce?

Answer - To launch one Flow from within another, you would use the Subflow element. It's like breaking down your Flows into smaller, reusable chunks that can be called whenever you need to use the same logic again.

Question 7: What is Flow Trigger Explorer in Salesforce?

Answer - The Flow Trigger Explorer shows all the Flows connected to a particular object and activates whenever a record linked to that object is added, modified or removed.

Question 8: Is the Screen element available while creating a Record-triggered Flow?

Answer - No, Screen elements are exclusively accessible for creating Screen Flows and cannot be used otherwise.

Question 9: What is the purpose of the Collection Sort elements in a Flow?

Answer - You can use this element when you have a bunch of records you want to organize. With the Collection Sort element, you can pick how many records to keep once they've been sorted.

Question 10: Can we call an invocable method using Salesforce Flows?

Answer - Yes we can call an invocable method using Salesforce Flows

Question 11: What is the difference between Before Save and After Save in Salesforce Flow?

Answer - If your aim is to modify fields on the record that initiate the flow, the Before Save option is useful. It triggers when the record is created, updated or deleted, offering faster performance compared to the 'After Save' flow.

With 'Before Save,' the focus is solely on updating the triggering record. Notably, Before Save doesn’t support setting up a scheduled path for time-based actions.

If you want to update different records or execute actions such as sending emails or calling subflows, the After Save option is suitable. It activates when the record is created, updated or both. However, unlike Before Save flows, it doesn’t trigger upon record deletion.

In After Save flow To update a record, you'll need to use the Update Records element instead of the Assignment element, which won't modify the record.

Question 12: When is it better to use Salesforce Flow instead of Apex triggers?

Answer - When both Salesforce Flows and Triggers can meet a requirement, prioritize using Salesforce Flows as they are easier to comprehend and maintain, even by Salesforce administrators.

Additionally, considering Salesforce's order of execution where Before Save Flows precede Before Triggers, it further adds the advantage of favouring the use of Salesforce Flows over triggers.

Question 13: What's the process for running a Flow asynchronously in Salesforce?

Answer - In the Record-triggered Flow enable the following checkbox.

"Include a Run Asynchronously path to access an external system after the original transaction for the triggering record is successfully committed”.

Add Flow element to the Run Asynchronously Path

Question 14: Can we use LWC inside Record-Triggered Flow?

Answer - No, the use of LWC (Lightning Web Components) isn't supported within a record-triggered flow. However, it's compatible with a Screen Flow.

Question 15: What are the best practices while working with Salesforce Flows?

Answer - The following are the Best practices to keep in mind while working with Salesforce Flows:

• Document your Flow
• Consider reusing existing Flows.
• Always perform a null check.
• Plan for error handling and ensure the inclusion of informative error messages.
• Don't perform DML operations inside a loop.
• Conduct testing before deployment to catch any potential issues early in the process.
