Q1. Tell me about yourself
Answer:
(Provide a brief professional summary highlighting your experience with RPA, Blue Prism, and relevant skills. Example below)
"I am an RPA developer with [X] years of experience in Blue Prism, specializing in designing, developing, and deploying automation solutions. I have expertise in process automation, work queue management, exception handling, and integrating Blue Prism with various applications. I have successfully automated [mention key processes] and optimized workflows to improve efficiency."
Q2. Blue Prism Architecture
Answer:
Blue Prism follows a client-server architecture with the following components:
Application Server – Hosts the Blue Prism database (SQL Server) and manages sessions.
Runtime Resources (Bots) – Execute processes on virtual machines (VMs).
Control Room – Monitors and manages bots, work queues, and schedules.
Development Studio – Used to design automation processes.
Release Manager – Handles bot deployment.
Database Server – Stores configurations, logs, and work queue items.
Q3. Why You Use Application Server
Answer:
The Application Server centralizes process execution, manages database connections, and ensures secure communication between Blue Prism components. It allows multiple bots to access shared resources and work queues efficiently.
Q4. How You Will Manage Work Queue
Answer:
Adding Items: Use "Add to Queue" action in Blue Prism.
Processing Items: Bots fetch items using "Get Next Item" based on priority.
Status Updates: Mark items as Pending, Completed, or Exception.
Exception Handling: Use "Defer" or "Exception" status for failed items.
Q5. How You Will Define Global Variable
Answer:
In Process Studio, right-click on "Data" → "Add Global".
Define Name, Data Type, Initial Value, and Exposure (if needed for external use).
Q6. How You Will Manage Work Queue Priority
Answer:
Assign Priority (1=Highest, 5=Lowest) when adding items.
Use "Get Next Item" with Priority Order to fetch high-priority items first.
Adjust dynamically using "Set Priority" action if needed.
Q7. Scenario: Same Excel File Opened by Multiple Bots on Different VMs
Answer:
Option 1: Use "Read Range" to load data into a Collection and close the file.
Option 2: Implement file locking (check if file is in use before opening).
Option 3: Split the Excel into multiple files for parallel processing.
Q8. Scenario: Managing Work Queue Priority Across Multiple Machines
Answer:
Ensure Work Queue is centralized (same database).
Bots fetch items based on priority order (highest first).
Use "Tagging" to assign specific items to specific bots if needed.
Q9. Scenario: High Volume Requests with Limited Bots (24x7 Running)
Answer:
Optimize Bot Speed: Reduce delays, improve efficiency.
Increase Concurrent Sessions: If VM resources allow.
Adjust Work Queue Priority: Process critical items first.
Use Resource Pooling: Share bots efficiently.
Q10. What is Global Variable?
Answer:
A Global Variable is accessible across multiple processes in Blue Prism. Defined in Process Studio, it retains value throughout the session.
Q11. What is Environment Variable?
Answer:
An Environment Variable is a system-level variable used to store configurations (e.g., file paths, URLs). Accessed via "Get Environment Variable" action.
Q12. What is Resource Pooling?
Answer:
Resource Pooling allows multiple processes to share a set of bots (runtime resources) dynamically, improving efficiency and load balancing.
Q13. Can You Create Parent-Child Process?
Answer:
Yes, in Process Studio:
A Parent Process can call a Child Process using "Start Process" action.
Data can be passed via Input/Output parameters.
Q14. What is Priority Data Type in Work Queue?
Answer:
Priority is an integer (1-5) where:
1 = Highest Priority
5 = Lowest Priority
Q15. How You Will Deploy Bot in Blue Prism?
Answer:
Export the process as a Release Package (.bprelease).
Use Release Manager to import and deploy to the Control Room.
Schedule or trigger execution via Control Room.
Q16. What is Extension of Blue Prism Bot Package?
Answer:
The Blue Prism bot package has the extension .bprelease.
Final Tips for Interview:
Be ready for practical scenarios (e.g., exception handling, queue management).
Explain real-life projects where you used Blue Prism.
Mention best practices (logging, error handling, secure credentials).
Would you like any answers explained in more detail? 😊
Certainly! Below are detailed answers to your additional Blue Prism interview questions, covering practical scenarios, real-life project examples, and best practices.
1. Practical Scenarios (Exception Handling, Queue Management)
Scenario 1: Exception Handling in Blue Prism
Problem: A bot fails while processing a work queue item due to an application crash.
Solution:
Use Recovery & Resume: Implement Recovery Stages in the process to retry or log exceptions.
Exception Work Queue: Mark failed items as "Exception" and notify support teams.
Logging: Capture screenshots and logs using "Log Exception" action.
Retry Logic: Use "Defer" status to retry later.
Scenario 2: Work Queue Deadlock (Multiple Bots Stuck on Same Item)
Problem: Two bots try processing the same queue item simultaneously.
Solution:
Use "Lock Item" → Ensures only one bot processes an item at a time.
Tagging: Assign specific items to specific bots.
Database-Level Locks: Configure SQL to prevent duplicate processing.
Scenario 3: High-Priority Item in Work Queue
Problem: Urgent requests must be processed before others.
Solution:
Set Priority (1=Highest, 5=Lowest) when adding items.
Use "Get Next Item" with Priority Order → Fetches high-priority items first.
Dynamic Priority Adjustment: Use "Set Priority" action mid-process if needed.
2. Real-Life Projects Using Blue Prism
Project 1: Invoice Processing Automation
Objective: Automate extracting invoice data from emails/PDFs into SAP.
Solution:
Used OCR (ABBYY/Blue Prism’s Decipher) for PDF extraction.
Work Queue managed pending/completed invoices.
Exception Handling for mismatched data (logged in Excel).
Result: Reduced processing time by 80%, eliminated manual errors.
Project 2: HR Employee Onboarding
Objective: Automate creating user accounts in Active Directory & HRMS.
Solution:
Input from Excel → Validate → Create AD Account → Send Welcome Email.
Work Queue tracked pending onboarding requests.
Error Handling for duplicate entries (auto-notified HR).
Result: Onboarding time reduced from 2 days to 30 mins.
Project 3: Banking Transaction Reconciliation
Objective: Match bank statements with internal records.
Solution:
Blue Prism fetched data from Excel & Core Banking System.
Fuzzy Matching for minor discrepancies.
Exception Queue for unresolved mismatches (reviewed manually).
Result: 99.5% accuracy, saved 200+ hours/month.
3. Best Practices in Blue Prism
A. Logging & Auditing
✔ Use "Log Message" for tracking bot actions.
✔ Capture Screenshots on Errors for debugging.
✔ Store logs centrally (SQL DB/Elasticsearch).
B. Error Handling
✔ Use Recovery Stages for retry logic.
✔ Classify Exceptions (Business vs. System Errors).
✔ Notify Teams via email/Slack on critical failures.
C. Secure Credentials
✔ Use Credential Manager (never hardcode passwords).
✔ Encrypt Sensitive Data in Global/Environment Variables.
✔ Limit Access to Control Room based on roles.
D. Work Queue Optimization
✔ Set Proper Priority (1-5) for urgent tasks.
✔ Use Tags to assign tasks to specific bots.
✔ Monitor Queue Health (pending vs. completed ratio).
E. Performance & Maintenance
✔ Avoid Infinite Loops (use loop counters).
✔ Close Applications Properly after use.
✔ Schedule Regular Maintenance (DB cleanup, log rotation).
