RPA Interview Questions
Robotic Process Automation (RPA) enables businesses to automate tasks across applications and systems, exactly as if they were being performed by a human employee. RPA eliminates manual errors, allowing employees to focus on more strategic tasks.
RPA provides real-time visibility into the finding of bugs and defects. RPA is a software technology that makes it simple to create, deploy, and operate software robots that mimic human movements while dealing with digital software and services.

Robotic Set of codes that mimic human actions are known as Robots.
Process The process can be described as the sequence of steps that creates a meaningful activity.
Automation The process performed by robots without human intervention.
The characteristics of RPA are :
User-friendliness : RPA software are easy to use and comprehensible. The best part is that there is no specific skillset required to operate the software.
Increased efficiency : Since there are no humans involved in RPA, there are barely any chances of human error. As long as the input data is correct, the process will also remain error-free.
Non-disruptive : It is very easy to deploy tasks to an automated robot and perform process transformation.
Coding-free : There is no requirement for employees who understand codes and programming.
There are six steps involves in the process of RPA. These are :
* Identifying the need for automation and the areas where it can be implemented
* Optimizing the processes where there is a need for automation
* Building a business case
* Selecting the right vendor of RPA
* Modeling the development of RPA
* Building expert RPA bots
* Barcode Scanning
* Invoice Processing
* Information Validation
* Open mail and attachments 
* Fill in forms and move files and folders.
* Follow if-then decision rules.
* Connect to system APIs
* Extract structured data from documents
* Make complex calculations
* Monitor manual processes and learn how to automate them
* Copy and paste
* Read and write to databases
* Scrape data from documents
* Login into web/enterprise applications
Reduces costs : One of the important advantages of RPA is the quick reduction in costs. By automating tasks, an organization can save up to 30 percent of their total costs because software robots cost less than a full-time employee.

Reduces operational risks : Some companies prefer to outsource busy work to third party organizations, and this comes with the risk of human errors and inefficiency. RPA offers a better solution—because the work stays in-house, there is less operational risk. 

Quality and accuracy : Processes with a high risk of human error can be automated using RPA systems. These bots are reliable, consistent, and can work tirelessly.

Scalability : With the help of RPA, companies can make adjustments based on changing conditions and can easily scale up or down operations as needed. 

Reduced workload : Automating tasks like report-making can significantly reduce the workload on employees, allowing them to focus on other critical tasks.

Improved customer satisfaction : Since accuracy is increased and operational risk is minimal, customers better quality content.

Improved business results : Since employees are focusing on activities that add more value to the company, robotic process automation enables businesses to achieve better overall results.
Popular RPA tools help professionals configure tasks and build bots to automate them. These include : 
Blue Prism : Blue Prism is a trading name of UK based software corporation, Blue Prism Group. The term 'Robotic Process Automation' was initially innovated by Blue Prism Group. Blue Prism helps organizations to automate repetitive, rule-based digital business processes in an agile and cost-effective manner.
UiPath : UiPath offers Windows-based desktop Robotic Process Automation. It supports a high range of automation in desktop, web, Citrix, and many other applications.
Automation Anywhere : Automation Anywhere is another popular RPA tool. It offers a user-friendly platform to automate complex business processes. It can be used to automate a vast amount of tasks, from basic windows configuration processes to the ultimate networking and remote database processes.
Pega : Pega is an RPA tool that can be used to automate the routine tasks which are repeated in a workflow. It adds the ability to automate tasks using the UI of existing applications. It can be beneficial to speed up manual tasks by automating user actions.
WorkFusion : WorkFusion is a SaaS (Software-as-a-Service) cloud computing platform. It automates the monitoring of data feed and helps you to manage crowd-sourced workers from global talent markets. WorkFusion uses statistical quality control to ensure the accuracy of the work output.
* RPA cannot be used for the processes that require judgment.

* RPA cannot learn from experiences.

* It cannot understand the unstructured inputs that are non-electronic.

* RPA enhances the efficiency of workflows by replacing human tasks with automated tasks. However, there are some limitations to the types of tasks on which it can be implemented.
The various reasons as to why RPA is the world's fastest-growing enterprise software :
* Return on investment is quick and big (ROI).
* It increases employee productivity by diverting them from monotonous duties and allowing them to focus on more productive, revenue-generating jobs.
* Software bots are far more accurate and have higher throughput than humans.
* It has a low-code build environment. RPA tools have a drag-and-drop feature that can be used to automate tasks. Code may be easily dragged and dropped.
RPA does not necessitate any special abilities or skills. Anyone with some basic knowledge or training, which is also of a short period, can become an RPA certified professional. The majority of RPA tools provide a user-friendly platform that can be used to easily automate activities using a flowchart-like layout. RPA tools have a drag-and-drop feature that can be used to automate tasks. Code may be easily dragged and dropped. As a result, users do not need to know how to code in order to automate processes.
To combine different systems, traditional automation relies on application programming interfaces (APIs) and other technologies. The developer should be well-versed in the target system. It is used to carry out programmatic instructions that have been pre-defined.  
Robotic process automation, on the other hand, imitates a user's activities at the user interface (UI) level. The developer doesn't have to worry about the underlying intricacies as long as the bot can follow the steps. It's a non-instructive, scalable, and adaptable system.  It's used to imitate human actions that are repetitive and follow a set of rules. RPA has a short implementation time. When compared to traditional automation, it takes less time. The implementation process takes several months.
