👋 Introduction

Whether you're a Power Platform developer, a business user, or prepping for a job involving Microsoft Power Automate, you're likely to face a few real-world interview questions. This article walks you through commonly asked Power Automate interview questions, answers, and mini-examples to help you speak with confidence in interviews.

Let’s break them down one by one — simple, clear, and with human-style explanations.

✅ 1. What is Power Automate?

Answer:
Power Automate (formerly Microsoft Flow) is a cloud-based service from Microsoft that allows users to automate workflows across different applications and services. It helps in connecting apps like SharePoint, Outlook, Excel, Teams, and many more — all without writing much code.

Example:
Automatically send an email notification when a new item is added to a SharePoint list.

✅ 2. What's the difference between Cloud Flow, Desktop Flow, and Business Process Flow?

Answer:

  • Cloud Flows: Runs in the cloud, triggered by events (e.g., an email arrives).

  • Desktop Flows: Used for RPA (Robotic Process Automation), automating UI-based tasks on your computer.

  • Business Process Flows: Guide users step-by-step through business processes inside Dynamics 365.

Use-case:
Desktop flow might automate filling out a legacy Windows application form.
Cloud flow could send reminders when a file is uploaded to OneDrive.

✅ 3. What types of triggers are available in Power Automate?

Answer:
Triggers start your flow. Common types include:

  • Automated triggers (e.g., when a file is created in OneDrive)

  • Manual triggers (user clicks a button)

  • Scheduled triggers (runs every day at 8 AM)

Example:
A flow that triggers when a new email is received with an attachment and saves it to SharePoint.

✅ 4. How do you handle errors in a Power Automate flow?

Answer:
You can use Configure Run After settings and parallel branches to handle errors gracefully. You can also use Scopeactions with Try-Catch-Finally pattern.

Mini Example:

[Scope: Try]
 → Get Items from SharePoint

[Scope: Catch]
 → Send an error email if the above fails

[Scope: Finally]
 → Log the outcome

Use the "has failed" or "has timed out" options to control the path.

✅ 5. What are dynamic content and expressions?

Answer:

  • Dynamic content allows you to reuse output values from previous actions (like a file name, email address, etc.).

  • Expressions use the Power Fx formula language to manipulate data.

Example:

substring(triggerBody()?['subject'], 0, 10)

This gets the first 10 characters of an email subject line.

✅ 6. How do you connect Power Automate to external services?

Answer:
You use connectors. Power Automate has 500+ built-in connectors for services like Twitter, Salesforce, Outlook, etc. You can also:

  • Use HTTP actions for REST APIs

  • Create custom connectors for internal APIs

Example:
Use HTTP POST to send data to a third-party API.

✅ 7. Can Power Automate handle approvals?

Answer:
Yes! Power Automate has a built-in Approvals connector that supports:

  • Start and wait for an approval

  • Custom approval types

  • Approve/Reject via email or Teams

Use-case:
Leave request approval flow where the manager can approve via email.

✅ 8. What limitations should you be aware of?

Answer:

  • API call limits (depends on license)

  • Timeout limits (e.g., 30-day flow timeout)

  • File size and row limits in Excel connectors

  • Premium connectors require per-user/per-flow plans

✅ 9. How do you test and debug a flow?

Answer:

  • Use Flow Checker to find design-time issues.

  • Run history shows each step’s input/output and errors.

  • Use Terminate and Compose actions to help with debugging.

Pro tip:
Use “Peek code” to view the raw JSON and understand the structure.

✅ 10. How do you secure a Power Automate flow?

Answer:

  • Use environment variables and Data Loss Prevention (DLP) policies.

  • Avoid hardcoding credentials.

  • Store secrets in Azure Key Vault or environment variables.

🎯 Bonus: Mini Flow Example

Scenario: Send a daily email with weather info.

Steps:

  1. Trigger: Recurrence (every day at 8 AM)

  2. Action: HTTP GET to weather API

  3. Action: Parse JSON

  4. Action: Send Outlook email with weather summary
