In this article of UiPath interview questions, we will be discussing the top most frequently asked UI Path interview questions for fresher as well as experienced candidates.
Before discussing UIPath Interview questions, lets first discuss about basic RPA interview questions:
Q-1) What is Robotic Automation?
Ans: Robotic automation is a style of automation where a computer mimics a human action.
Q-2) What is RPA?
Ans: Just like people, software robots can do things like understanding what’s on a screen, completing the right keystrokes, navigating systems, identifying and extracting data, and performing a wide range of defined actions. But software robots can do it faster and more consistently than people, without the need to get up and stretch or take a coffee break.
Robotic process automation (RPA) is a software technology that makes it easy to build, deploy, and manage software robots that emulate human actions interacting with digital systems and software.
Robotic Process Automation is the process of automating tasks with the help of software/tools which will reduce the involvement of humans to perform any task.
Q-3) List various stages of the RPA life cycle?
Ans: Various stages of RPA life cycles are: 1) Discovery phase, 2) solution design phase, 3) development phase, 4) user acceptance tests, 5) development and maintenance phase, and 6) execute bots.
- Discovery Phase – As the name suggests, in this phase, the requirements of the client are analyzed to decide whether the process can be automated or not. After that, the complexity of the process is analyzed along with the benefits.
- Solution Design Phase – The solution or the steps to automate a task is designed in this phase. Apart from the basic requirements, a few other requirements for the project such as Budget, Time to be spent, the number of people working on the project are decided. Then an Object Model Diagram or a Flowchart is created to understand the flow of the process.
- Development Phase – The Development Phase is the phase wherein the Automation Developer creates Automation Scripts in the chosen RPA Tool. Depending on the task to be automated or the kind of automation required, there may or may not be coding required.
- UAT(User Acceptance Tests) – In this phase of the RPA lifecycle, the developed bot is tested either by the Testing team or the Development team itself. The bot is tested in the pre-production environment to test how the users can use this bot to automate a specific task.
- Deployment & Maintenance Phase – After developing and testing a bot, the bot is deployed into the production environment.
- Execute Bots – In this stage, the bots are executed and thereafter checked to generate meaningful results.
Q-4) What are the different things that can be automated using RPA?
