UiPath’s Orchestrator is a centralized platform for managing, deploying, monitoring, and scheduling bots. It also tracks transaction logs, handles exceptions, and allows bot collaboration.

Coding Question:

23. Write a UiPath script to check if a file exists and, if so, move it to another folder.

• Solution:
  • Step 1: Use the “If” activity to check file existence (File.Exists(path)).
  • Step 2: Use the “Move File” activity to transfer it to the target location if it exists.

24. Explain the difference between sequence and flowchart workflows in UiPath.

Sequence workflows execute tasks in a linear order, ideal for simple, sequential processes. Flowchart workflows offer more flexibility, allowing conditional logic and branching, making them suitable for complex processes.

25. Describe how you’d handle a transaction in UiPath REFramework.

In REFramework, each transaction is handled within a “Process Transaction” state, where activities are executed and exceptions are managed. REFramework retries failed transactions, logs errors, and follows an organized structure to handle each transaction separately.

26. What’s the role of Citrix automation, and when would you use it?

Citrix automation enables bots to interact with virtual environments like remote desktops. It uses image recognition and OCR since virtual applications cannot be accessed through normal UI elements.

27. How do you handle duplicate transactions in RPA?

When answering, outline your role, the project’s objectives, challenges encountered (like handling unstructured data or dealing with UI changes), and solutions implemented. Tailor the response to show problem-solving skills and adaptability.

Scenario-Based Questions

31. A bot fails when processing certain invoices from a PDF folder. How would you troubleshoot?

I would first analyze whether the PDFs follow a consistent structure. For structured invoices, anchor-based extraction ensures correct data retrieval. For unstructured or scanned invoices, I would use Document Understanding with OCR engines to extract data accurately. Low-confidence extractions would be routed to a human validation queue for verification. Exception handling ensures that one failure doesn’t stop the entire batch, and logging captures detailed information for troubleshooting.

32. The bot intermittently fails when logging into a web application. What would you do?

I would inspect whether the web elements have dynamic attributes or if page elements load inconsistently. Using activities like Element Exists, On Element Appear, or Retry Scope allows the bot to wait for elements reliably. I would also verify that credentials are stored securely in Orchestrator Assets and that the login workflow handles incorrect or expired credentials gracefully. Logs and screenshots help identify exactly why the login failed.

33. A process is slow because thousands of transactions need processing daily. How do you optimize it?

I would implement Orchestrator queues to manage transactions efficiently and allow multiple unattended robots to process items in parallel. Workflow optimization includes using modular components, avoiding unnecessary UI automation, and leveraging background processes when possible. Monitoring performance with logs and analytics helps fine-tune processing speed and identify bottlenecks.

34. Unexpected pop-ups interrupt workflow execution. How do you handle them?

I would build a reusable pop-up handler that monitors for unexpected windows and dismisses them safely. Global Exception Handling ensures that interruptions are captured and handled without stopping the main workflow. Using retry logic and safe navigation strategies allows the automation to continue reliably even in unpredictable application environments.

35. A bot writes duplicate records to a database when network latency occurs. What would you do?

To prevent duplicates, I would implement idempotent operations by checking whether the record already exists before insertion. Unique transaction IDs or primary keys ensure database integrity. Proper transaction handling, along with logging every processed record, allows for accurate monitoring and avoids reprocessing due to intermittent failures or latency.

36. Selectors break after a recent UI update in the application. How would you make the bot stable?

I would replace fragile selectors with resilient ones using wildcards, anchors, or Computer Vision for complex UI elements. Modularizing workflows ensures that any selector changes can be updated in one place, minimizing maintenance. Testing the updated selectors after every application release ensures the bot runs smoothly in production.

37. The bot must read data from multiple Excel sheets and some have inconsistent formats. How would you handle this?

I would add validation logic to detect variations in headers or column positions. Try-Catch blocks ensure that errors in one sheet don’t halt the entire process. Data standardization before processing allows downstream activities to work with consistent input. Logging and exception handling provide transparency on which rows or sheets caused issues.

38. Your bot should run unattended, but it requires human approvals during execution. How do you design it?

I would separate human-dependent steps into dedicated queues and assign approval tasks to specific users via Orchestrator. The bot can continue processing other transactions that don’t require approval. This approach maintains unattended execution while integrating necessary human validation efficiently.

39. Automation is needed on a legacy desktop application with no accessible selectors. What’s your approach?

I would use image-based automation or keyboard navigation where standard selectors aren’t available. For more reliable operation, Computer Vision activities can help identify UI elements even on legacy systems. Where possible, I would also access backend APIs or databases directly, avoiding fragile front-end interactions altogether.

40. The client changes business rules frequently. How do you ensure the bot can adapt without constant code changes?

I would externalize all business rules into configuration files or Orchestrator Assets. Modularizing workflows separates business logic from automation logic, making updates easier. Changes would be tested in UAT before deployment, and proper version control ensures safe rollbacks if needed. This approach reduces maintenance overhead and keeps the automation robust.
