Blue Prism Interview Questions for Freshers
1. What is Blue Prism’s Robotic Process Automation (RPA)?
Blue Prism RPA is a tool that helps companies automate repetitive tasks. These tasks are usually based on rules, and Blue Prism RPA uses software bots to do them. Software bots are capable of doing tasks such as clicking, typing, and transferring data between applications.
2. Which components form the Blue Prism system?
Blue Prism consists of four main components that support automation development and execution.
- Process Studio – Designs business processes.
- Object Studio – Creates application interaction objects.
- Control Room – Monitors and runs bots.
- System Manager – Manages users and system settings.
3. What is the main difference between Process Studio and Object Studio?
- Process Studio
- Design the workflow of a business process.
- It is used to make decisions and figure out the logic of the process.
- Object Studio
- Interact with applications like SAP or web browsers.
- It is used to do actions like clicking buttons or entering data into fields.
4. What is the role of the Application Modeller, and what spy modes does it use?
Application Modeller is used to identify elements of an application so bots can interact with them. It helps Blue Prism recognize buttons, fields, and objects.
Spy modes include:
- Win32 – Desktop applications
- HTML – Web applications
- Region – Citrix/virtual environments
5. What is the purpose of a Business Object in Blue Prism?
A Business Object in Blue Prism is something that you create in Object Studio. It helps Blue Prism talk to applications. A Business Object in Blue Prism acts like a bridge between the Blue Prism process and other systems.
6. What are the data types supported in Blue Prism?
Blue Prism supports various data types used in automation processes.
- Text
- Number
- Date
- DateTime
- Flag (Boolean)
- Password
- Binary
- Timespan
- Image
7. What is a “Collection” in Blue Prism?
A Collection in Blue Prism is like an Excel sheet. It is used to store lots of data in rows and columns. A Collection in Blue Prism makes it easy to handle lots of data at one time.
8. Explain the “Wait” stage.
The Wait stage ensures that an application element is available or ready before the bot proceeds. It helps prevent errors caused by timing issues.
Example uses:
- Waiting for a page to load.
- Waiting for a button to appear.
9. What is a Data Item and a Session Variable?
- A Data Item in Blue Prism is used to store one piece of information, like some text or a number, while a process is running.
- A Session Variable is a kind of variable that can be changed while the process is running, from the Control Room, without having to change the process.

10. What is Exception Handling?
Exception handling is the process of managing errors during bot execution. It ensures that the automation does not fail when an error occurs.
It uses:
- Recover stage – To catch errors.
- Resume stage – To continue execution.
11. What is a Work Queue?
A Work Queue is used to store and manage large volumes of work items in Blue Prism. It helps process tasks in a controlled and efficient way.
Features:
- Stores transactional data
- Supports priority-based processing
- Allows retry for failed items
12. What is the main difference between a Thin Client and a Thick Client?
- Thin Client
- Applications are hard to automate.
- This is because it is difficult to find the things you need to automate, like in Citrix environments.
- Thick Client
- Applications are easy to automate.
- This is because you can get to the things you need to automate, like in SAP or desktop applications.
13. What is the main difference between Global Variables and Data Items?
- A Data Item is used in one part of a process or object.
- A Global Variable can be used in parts of a process or object, which makes it more useful. Global Variables are accessible from different places, but Data Items are not.
14. What are the different types of Action stages?
Action stages are used to perform different operations in Blue Prism.
- Action Stage – Calls a business object.
- Calculation Stage – Performs calculations or assigns values.
- Decision Stage – Works like an if-else condition.
15. What does the Control Room do in Blue Prism?
Control Room is the central monitoring and management hub in Blue Prism. It is used to control all running bots and processes.
Functions:
- Start and stop processes
- Schedule automation tasks
- Monitor bot performance
- Track work queue status
Blue Prism Interview Questions for Experienced Candidates
1. What is the difference between the Exception Handling stages: Recover and Resume?
- Recover
- Catches an exception (error) in a block.
- Transfers control to the error handling path.
- Resume
- Clears the exception after handling.
- Allows the process to continue normally.
2. Explain the purpose of the Preserve checkbox in an Exception Stage.
The Preserve checkbox helps when you re-throw an exception. It keeps the error type and message instead of changing it to a new one. This is helpful because it lets developers find the reason for the issue even after they log or handle the error.
3. What are the different types of Spying Modes in Blue Prism?
- Win32 – For standard Windows applications
- HTML – For web-based applications
- Accessibility (MSA) – For apps not recognized by Win32 or HTML
- Region – For Citrix or virtual environments

4. How do you handle dynamic selectors in Blue Prism?
Dynamic elements (like changing IDs or names) are handled using flexible identification techniques.
- Use wildcard characters (*, ?)
- Use attribute matching instead of exact values
- Use index-based identification
- Avoid unstable attributes
5. Explain “Environment Locking” and when to use it.
Environment Locking makes sure one bot uses a shared resource at a time. This stops conflicts and data corruption from happening. You use it when working with shared files, old systems, or applications that can’t handle users at once.
6. How do you implement a Retry Mechanism in Work Queues?
- Use the Get Next Item action.
- Set Max Attempts in the queue configuration.
- Use Mark Exception when a failure occurs.
- Blue Prism automatically retries based on settings.
7. What are the advantages of using Work Queues?
Work Queues improve automation efficiency and scalability.
Key benefits:
- Load balancing across bots
- Automatic retry mechanism
- Real-time reporting
- Maintains audit trail
8. Explain the difference between Foreground and Background processes.
- Foreground processes work directly with the user interface. Need an active screen to run.
- Background processes run without interacting with the UI. Can do multiple things on the same machine at the same time.
9. How do you securely handle passwords in Blue Prism?
- Store passwords in Credentials (System tab)
- Use the Get Password action to retrieve them.
- Avoid hardcoding passwords
Prevent exposure in logs.
10. What is Surface Automation?
Surface Automation is used when application elements are not accessible through normal spying methods.
It works using:
- Screen regions
- Image recognition
- Coordinate-based actions
It is commonly used in Citrix or remote environments.
11. How do you handle an unresponsive application?
If an application stops responding, the bot should handle it carefully to avoid failure.
Approaches:
- Use the Wait Stage to check responsiveness.
- Check for element existence.
- Terminate and restart the application if needed.
12. Can you explain the purpose of a Wait Stage?
A Wait Stage stops the process until something specific happens, like an element shows up or a page finishes loading. This matters because it stops errors that happen because of timing issues and makes sure everything runs smoothly.
13. What are the best practices for exception handling in a production process?
- Use structured blocks (like Try-Catch logic)
- Capture screenshots for errors.
- Log detailed error messages.
- Use a retry mechanism for temporary failures.
- Always clean up before ending the process.
14. What are the types of session variables?
Session variables are used during a running process session and can be updated dynamically.
Common examples include:
- Session ID
- Machine name
- User details
- Runtime configuration values
15. What is the role of an Environment Variable in RPA?
An Environment Variable is a system-level value in Blue Prism that can be updated without changing the process or object.
Uses:
- Store file paths, URLs, or email IDs
- Quickly move between Dev, Test, and Production environments.
It helps make automation flexible, reusable, and easy to maintain.
