Intermediate Blue Prism Interview Questions

11. What is a Work Queue?

Work Queues are used to manage transactional data. They enable bots to process high-volume tasks concurrently and handle exceptions effectively.

12. What are Sessions in Blue Prism?

A session is an instance of a process being executed on a runtime resource. Each session has its own execution log and can be monitored in the Control Room.

13. What is the difference between Launch and Attach in Blue Prism?

• Launch: Opens a new instance of the target application.
• Attach: Connects to an already open instance of the application.

14. How do you handle exceptions in Blue Prism?

• Recover Stage: Used to catch exceptions.
• Resume Stage: Used to continue after handling exceptions.
• Exception Stage: Used to throw custom errors.

15. Explain the difference between Resume and Recovery.

• Recovery catches the exception.
• Resume allows the process to continue after an exception is caught.

16. What is a Collection in Blue Prism?

A collection is a data type that holds a group of related items in tabular form—like an Excel spreadsheet or database table.

17. What is a Decision Stage?

Used to apply logical conditions in workflows. It evaluates expressions like If, Else, or And/Or logic in flow paths.

18. What is the purpose of the Calculation Stage?

To perform arithmetic or string-based calculations and assign results to data items.

19. What is the use of the Wait Stage?

It delays the process execution until a specific UI element appears or a timeout is reached. Useful for ensuring sync with external applications.

20. How do you optimize performance in Blue Prism processes?

• Use efficient loops and logic.
• Reuse VBOs instead of duplicating code.
• Use collections instead of single data items for batch operations.
• Avoid unnecessary screens or pop-ups.

Advanced Blue Prism Interview Questions

21. What is the difference between a Page and an Action?

• Page: Sub-process inside a process.
• Action: Defined inside an object and reused across processes.

22. What is Surface Automation in Blue Prism?

Used when Blue Prism cannot interact directly with application elements. It uses image and coordinate-based automation (OCR, pixel matching).

23. How is version control handled in Blue Prism?

Each process or object has a version history. Changes can be published or rolled back using Release Manager.

24. What are the limitations of Blue Prism?

• No direct support for unstructured data.
• Higher learning curve than some tools.
• Limited built-in AI/ML capabilities (needs integration with external tools).

25. Can Blue Prism be integrated with AI or ML tools?

Yes, via APIs or third-party integrations like IBM Watson, Google Cloud AI, or Microsoft Cognitive Services.

26. What is Dynamic Match Type in Application Modeller?

Allows you to create flexible match conditions for UI elements using parameters—useful when elements are dynamic or partially changing.

27. Explain Environment Locking in Blue Prism.

Prevents multiple bots from executing the same resource-sensitive task at once using Lock and Unlock logic.

28. How do you schedule a process in Blue Prism?

Using the Scheduler inside Control Room. You can configure time, frequency, and resource allocation for each process.

29. How does Blue Prism ensure security?

• Role-based access control (RBAC)
• Encrypted credentials and logs
• Integration with Active Directory
• Audit logging and session history

30. What is Global Exception Handling in Blue Prism?

A global recovery mechanism used when no localized exception handling is defined. It’s useful for catching unhandled errors across processes.

Scenario-Based Interview Questions

31. How would you handle unexpected pop-up windows during automation?

• Use Exception Handling around application interaction blocks.
• Use dynamic wait and image recognition.
• Predefine conditions using Wait or Read Stages.

32. How would you automate Excel data extraction and upload into a web app?

• Use Excel VBO to open and read the file.
• Store data in a collection.
• Use browser automation to map fields using Application Modeller.
• Loop through the collection and input data.

33. What would you do if two bots need access to the same resource?

Use Environment Locking or queue-based design to serialize execution and avoid conflict.

34. What if a bot fails halfway during a large data batch?

• Log the failed item.
• Use Retry Mechanism in Work Queues.
• Resume from the last checkpoint using Get Next Item.

35. How do you ensure error logging for compliance audits?

• Enable session logging.
• Use exception blocks to capture error messages.

37. What is the purpose of the Scheduler in Blue Prism?

The Scheduler automates the start of processes at specific times or intervals without human intervention. It ensures bots execute tasks during off-hours, weekends, or low-traffic periods.

38. What is the difference between Safe Stop and Immediate Stop?

• Safe Stop: Gracefully halts the process after completing the current stage or logic block.
• Immediate Stop: Forcefully terminates the bot’s session, even in the middle of execution. These options are available in Control Room.

39. What are Tags in Work Queues used for?

Tags help categorize or label queue items for filtering and processing specific subsets of data. For example, tagging an item as “urgent” or “pending-approval”.

40. What is the role of ‘Retire’ in Blue Prism?

Retiring a process or object means it’s no longer available for execution or changes. This is useful for managing outdated or legacy automations.

41. How do you debug a process in Blue Prism?

• Use Breakpoints to pause execution.
• Step through stages using Step Into, Step Over, and Step Out.
• Monitor data item values and logs in Control Room or Session Logs.

42. What is the purpose of the Anchor Base in Blue Prism?

Anchor Base is a concept used in Surface Automation when identifying elements on screen using visual references (e.g., relative positions) rather than direct selectors.

43. Can Blue Prism automate Citrix applications?

Yes, but it requires Surface Automation techniques like image recognition, OCR, and keystroke-based control since Citrix operates on a virtual desktop layer.

44. How do you move code from Development to Production in Blue Prism?
