About RPA
Robotic process automation (RPA) is the use of software with artificial intelligence (AI) and machine learning capabilities to handle high-volume, repeatable tasks that previously required humans to perform. These tasks can include queries, calculations and maintenance of records and transactions.
RPA Used
RPA can be used to automate workflow, infrastructure, back office process which are labor intensive. These software bots can interact with an in-house application, website, user portal, etc. The RPA is a software program which runs on an end user’s pc, laptop or mobile device.
Top Answers to RPA (Robotic Process Automation) Interview Questions
1. Compare Robotic Process Automation with traditional automation.
| Criteria | Robotic Process Automation | Traditional Automation |
| Technology | Non-intrusive, scalable, and versatile | Intrusive, less scalable, and not so versatile |
| Interface | Mimics human actions | Relies on coding and APIs |
| Customization | Excellent | Average |

2. What is RPA?
Robotic Process Automation (RPA) is a type of software that is used to do automation of the fundamental tasks in software applications like how a human performs them. The software robot can be trained for a workflow/process with different steps and application. It could be, for example, taking received forms, sending a receipt message, checking the forms for completeness, documenting the form in a folder, and updating a spreadsheet with the form name, the date recorded, etc. RPA programming is intended to diminish the weight of monotonous, straightforward tasks/work on workers.
3. List the different types of tools in RPA.
- Blue Prism
- UiPath
- Automation Anywhere
- WorkFusion
- OpenSpan
4. Describe the life cycle of RPA.
There are four different phases in the RPA life cycle:
- Analysis: Identifying the business process for which RPA development is needed
- Development of the Bot: Fulfilling the requirements
- Testing: Performing quality checks
- Deployment and Maintenance: Deploying and maintaining the bot by the team
5. How would you deploy UiPath?
- Install UiPath Studio on the system on which we want to automate processes
- To provision the machine, take the robot key from Orchestrator and enter it into the Robot Configuration board and, furthermore, the Configuration URL that can be found in the Admin section of Orchestrator

- Start job
6. How do you invoke a UiPath workflow?
Workflows are small pieces of common automation that are reusable and applicable in multiple scenarios. They are used to automate similar processes. We can invoke a workflow using the ‘Invoke Workflow’ function in UiPath and save it as a template. We can also combine two workflows to make combined automation.
7. What is Citrix Automation?
Citrix automation is used to automate processes such as filling fields in a form and submitting the form in a virtual desktop application. We can also use it for processes such as data entry, etc.

- Improved efficiency of tasks
- Performing the tasks quickly without errors
- Increased productivity
- Cost-saving
- Decreased turnaround time
12. How do you perform Screen Scraping in RPA?
Screen scraping is an essential component of the RPA toolkit. It is used to capture bitmap data from the screen and cross-check it with the stored information to decipher it.

- It is easy to implement and mostly accurate.
14. How can you differentiate RPA from Macros?
| Robots | Macros |
| Learn and enhance themselves from repetitive processes | Do not learn from repetitive processes |
| Can act autonomously | Cannot act autonomously |
| Respond to external stimuli and reprogram themselves | Do not respond to external stimuli |
| Highly secured automation | Security is not a high priority here |
15. What are the different automation frameworks used in software automation testing?
- Modular automation framework
- Keyword-driven framework
- Hybrid automation framework
- Data-driven framework
16. List the components of RPA Solution Architecture.
- Enterprise applications such as ERP Solutions (SAP)
- RPA tools, in any environment such as Citrix, web, or desktop
- RPA platform: Scheduling, distributing, and monitoring the execution of software bots
- RPA execution infrastructure
- Configuration management

17. What is Thin Client and Thick Client in RPA?
| Thin Client | Thick Client |
| Does not run on a local machine, rather runs on a virtual client/server architecture | Directly installed on a local machine |
| E.g., VMware, VirtualBox, etc. | E.g., any apps like notepad, browser, etc. |
18. List the limitations of RPA.
- Limitations to tasks like decision-making or judgmental tasks
- Not a cognitive computing solution, rather learns through experience
- Might be error-prone when subjected to new environments without experience
- Higher cost of implementation across the industry
19. Explain Flow Switch in UiPath.
Flow switch (aka flow decision) is a flowchart-specific activity that splits the control flow into two or more branches based on some conditions. Whichever condition is satisfied, that task is executed.
