RPA UiPath Interview Questions and Answers for Fresher
1. What is RPA?
RPA is an acronym for Robotic Process Automation.
Robotic
In RPA, Robotic is termed as an entity or machine which tries to mimic human actions or capable of doing complex tasks programmed by the computer.
Process
It is any meaningful task done by a sequence of steps.
Automation
Automation is doing a task without human intervention and, any entity which does a job without human intervention is known to be automated.
In a short and straightforward form, RPA is defined as mimicking human behavior/actions to execute a sequence of steps which lead to a meaningful activity automatically, i.e., without human intervention.
2. What are the phases of RPA lifecycle?
These are the phases of RPA lifecycle as follows:
Analysis
RPA lifecycle begins with Analysis as its first phase. Business team and RPA strategic/Architect work together to understand a business process for RPA development. This analysis is done mainly to identify the feasible processes for automation, save the manual effort, and bring Rol.
Bot Development
The developers of RPA team focus on requirements in their environment possibly a diverse dev environment.
Testing
Testing carries out by following the two approaches as below:
- Separate testing team
- Testing gets done by RPA development team only
Here the dedicated testing team is referred for best practice as it performs QA of a developed bot like SDLC flow.
Deployment and Maintenance
After the Development and Testing states, a bot is ready for deployment and enters the Maintenance phase.
A script/bot can be updated if any change comes in a process and in case any issue occurs in a bot then the same bot can be re-deployed by repeating the dev-test process.
3. What is UiPath Automation?
UiPath Automation is the merchant for the leading automation process of Robotics. It helps in providing a software platform which will help in an organization like automate business. The software robot mainly aims to help in the manipulation of the application's layer of presentation like the way any human does.

UiPath Robot: This component is the UiPath executor can interact with a large number of applications at the same time.
UiPath Orchestrator: It is a web application used to manage, monitor, and to schedule multiple deployed robots and processes.
6. What are the components of UiPath Studio?
These are the following
components of UiPath Studio as follows:
Ribbon: It has many parts like Recorder that allows users to record UI mouse movements and keyboard activities to generate automation scripts, Screen Scraping and Data Scraping that make scraping easy, User Events, and Variables.
Activity Pane: It contains all the small tasks available to drag and drop in the workspace and configure according to the needs of every activity.
Properties Pane: Configurations like setting the output of a particular activity or the task can be handled by using properties pane.
Control Bar/Pane: This component is used to create variables, delete variables and also to deal with arguments.
7. List the benefits of UiPath.
- UiPath is reliable and easy to use.
- It assists a quick automation process with the help of its drag and drops functionality.
- It facilitates seamless automation of data entry on any web form and desktop application.
- With the help of UiPath Orchestrator, you can launch the robots quickly.
- It offers 100% playback accuracy by saving countless man hours and requiring zero codings or scripting.
8. What are the limitations of UiPath Community Edition?
- Every time the Nugget Package Manager libraries get deleted and the tool asks for its activation.
- This edition is lack of local hosting of UiPath Orchestrator server.
9. List the UI Activities Properties in UiPath.
There are multiple activities used in automating apps which you can find in the Activities Panel under the UI Automation category. That UI activities have many common properties as follows:
- ContinueOnError specifies continuous working of automation even in the case of errors thrown by activities. It supports only Boolean values (True, False).
- DelayAfter helps to pause after the activity, in milliseconds.
- DelayBefore helps to pause before the activity, in milliseconds.
- TimeoutMS specifies the time amount (in milliseconds) to wait for a specified element that would be found before the error be thrown.
- WaitForReady waits for the target to be ready before performing the actions.
- Target identifies the UI element with which the activity works.
10. What are selectors and wildcards in UiPath?
Wildcards in UiPath are the symbols that help in replacing zero or multiple characters in a string. They help in dealing with the attributes that are changing dynamically in selectors.
Selectors in UiPath is a string of characters (VB expression) used to identify the objects on the screen. Selector Editor automatically generates the Selectors through wildcards.
11. Describe Recording in UiPath Studio.
Recording is an essential functionality in UiPath Studio that helps to capture user’s action on the screen and translate them. It is beneficial and saves a lot of time to automate whole business processes. Recording option locates under Design tab of UiPath Studio. Recording exhibits both Automatically Recordable Actions and Non-Recordable Actions.
These are the following four types of Recording that UiPath Studio provides:
Basic recording suits single activities. It is used to generate a full selector for each activity, but lack container and so automation becomes slower.
Desktop recording is suitable for multiple actions and desktop apps. It generates a container in which activities are enclosed having partial selector. It is faster than Basic recording.
Web recording is used for all types of recordings in web apps and browsers. It also generates a container and hence faster than Basic recording.
Citrix recording requires explicit positioning, permits only images, text, and keyboard automation. It records virtualized environments like VNC, Virtual Machines.
12. What is Automatic Recording in UiPath?
Automatic recording is utilized of being very useful and saves a lot of time. It provides a skeleton for your entire business processes so you can easily customize and parameterize the project. The automatically generated activities for the recordable actions are Click, Type Into, Check, and Select Item.
13. How UiPath differs from Selenium?
Selenium is specifically designed to test websites and web applications. In Selenium, it is impossible to interact with multiple applications and to take the output of an application as an input for another application. Selenium can’t work with virtualized environments like Citrix.
While UiPath is designed as an RPA tool to automate any existing software process to replace any activities that a human can perform.
And so it is observed that RPA is the next level of existing automation tools. It allows people to build a very complex rules-based process within few software development skills.
UiPath allows doing all the things which Selenium allows but vice-versa it is not possible.
14. Which kind of robots can be configured in Orchestrator?
Standard Robot is machine dedicated as it works on a single Standard machine only, namely the user-defined when creating it.
Floating Robot can use multi-machines such as it can work on any machine (Standard or Template) in Orchestrator because machine name is irrelevant when creating it.
15. Which function is used to invoke a UiPath workflow?
Use
Invoke Workflow function for invoking a UiPath Workflow and save that as a template.
16. List the steps to connect orchestrator to the robot?
Step 1: Open UiRobot in the system. Then it will populate in System Tray. Once it gets populated
Step 2: Go to System icon tray and
Step 3: Click UiPath Robo Icon.
Step 4: Then Click "Gear" icon > Settings > Provide orchestrator URL and Machine Key which is created in Orchestrator>Machine Group
17. What is the value and scope of UiPath data types?
Data types classify the type of value of the variable. A variable is utilized for storing numerous kinds of data having some value and its value can be changed. UiPath consists of an enormous number of data types beginning from the content number, nonexclusive esteem, time, date, generic value, and information tables.
18. Why do you use Data Scraping in UiPath?
Data Scraping helps to extract the structured data from the browser, document or application to a database or spreadsheet or .csv file. Structured data is a particular type of information in a predictable pattern. UiPath Studio facilitates data scraping with the help of scraping wizard which exists under the Design tab.
