Top UiPath Interview Questions and Answers for 2020

Robotic automation is a hot market today, and developers are looking for new ways to save time and money by automating otherwise dull and repetitive processing. We have barely begun to scratch the surface of Robotics and artificial intelligence (AI), and the potential benefits of increased automation are mind-boggling.

To that end, the world needs more robotic automation professionals, and consequently, companies are on the lookout for new talent, creating more UiPath jobs. UiPath is a popular automation tool in the robotic automation industry, and if you want to be part of that world, then you will need to ace that interview.

We’re here to help, so we present two dozen of the most common UiPath interview questions you will most likely face, grouped from Basic to Advanced. By studying these questions, you can refresh your automation knowledge and walk into that interview with extra confidence. These questions are relevant for whatever UiPath careers applicants are aiming for.

Basic UiPath Questions

1. What is UiPath? And What is RPA?

UiPath is a complete process automation platform that helps businesses and organizations efficiently automate their business processes. UiPath is also the name of the software company that developed the platform.

RPA stands for Robotic Process Automation and is the process involved in training robots to act like human beings and perform time-consuming, repetitive tasks.

2. Describe the advantages of using RPA.

There are four chief benefits of RPA:

  • Easy to use. Anyone can use UiPath to perform RPA tasks; the tools are simple.
  • Cost-effective. By assigning repetitive tasks to robotic processes, organizations can function with a smaller workforce.
  • No complicated coding needed. When using the UiPath tool to automate processes, the platform’s limited code handles most tasks.
  • Fast, efficient, and accurate. Once robots receive the correct data, they will execute the assigned tasks with limited to no error.

3. List the main phases of the RPA life cycle.

The four phases are:

  • Analysis. The UiPath developer teams and the business teams get together and decide on the RPA processes needed for RPA development.
  • Bot Development. The UiPath development team identifies the bots and develops them.
  • Testing. The development tests for defects and to ascertain overall quality levels. This testing procedure usually involves a dedicated testing team performing QA.
  • Support and Maintenance. The UiPath team distributes the bot and monitors live usage and resolves any errors that occur in the process.

4. What tasks can be automated using RPA?

These are just some of the tasks that RPA handles:

  • Data capture and manipulation
  • Data entry
  • Email sharing
  • Automating daily repetitive work within the system
  • Collecting information from various sources
  • Generating reports

5. Name the different components of UiPath.

The three components are:

  • UiPath Orchestrator. It’s an application used for project optimization, deploying UiPath robots anywhere you need them. You can Orchestrator to schedule, deploy, and monitor the bots, as well as generating appropriate reports.
  • UiPath Robot. Often called just “bot” for short, it lets you run your project on different systems, executing the automation workflow created in UiPath. The UiPath Orchestrator manages them
  • UiPath Studio. A studio is a tool used to design and develop your project. It handles application integration, and the tasks of third-party application automation, administrative IT tasks, and any business IT processes.

6. Discuss UiPath architecture.

There are three layers in UiPath architecture.

  • Client Layer. UiPath Robots and UiPath Studio reside here. UiPaths are, in turn, divided into UiPath Agent Service and UiPath Executor Service. The former shows available jobs in the system tray, and the latter runs the given tasks using a Windows session.
  • Server Layer. UiPath Orchestrator resides here.
  • Persistency Layer. This layer holds the database, which in turn takes care of queues and their items. It also contains information about robot configuration and their assigned processes.

7. Explain the difference between a thin and thick client.

Thin clients are applications where you cannot get quality properties by spying with any RPA tool, while thick clients are applications that yield plenty of attribute properties, using RPA tools.

8. How long does it take to build an operational agility framework?

In most cases, the timeframe ranges from four to 12 weeks, beginning at the date of the project’s commencement.

Intermediate UiPath Questions

9. What is an argument in the context of UiPath?

Arguments pass data from one workflow to another. For instance, they move data between projects, and have specific directions (e.g., In, Out, In/Out).

10. What’s the difference between data scraping in UiPath and screen scraping in UiPath?

Data scraping:

  • Extracts structural data
  • Stores scraped information in a data table
  • Efficiently extracts data into Excel or DB
  • Cannot collect data from images or PDFs

On the other hand, screen scraping:

  • Extracts non-structural data
  • Stores scraped information in a string
  • Cannot easily extract data into Excel or DB
  • Can pull data from images and PDFs

11. What are the properties in the context of UiPath?

Properties define the activities used to automate applications visible in the UiPath automation activity panel. Properties include ContinueOnError, Delay After, Delay Before, Target, TimeoutMS, and WaitForReady.

12. What is a flow switch in UiPath?

Flow switches and flow decisions are similar, but with one significant difference. Each branch of the flow switch is called a flow step and is not restricted to just a true or false branch.

13. What is a generic variable in UiPath?

This is a variable that can store any kind of data types (e.g., arrays, date formats, int, and strings).

14. What is a sequence activity in UiPath?

A sequence is a small project type that allows the path to switch from one activity to another easily. It is a single block activity, and these blocks are reusable.

15. What is exception handling, and what are the four options?

Exception handling most involves handling errors regarding various UiPath activities. The options are Rethrow, Terminate Workflow, Throw, Try Catch.

16. Speaking of the four Exception Handling options, what’s the difference between Terminate Workflow, Throw, and Rethrow?

Use Rethrow when you want activities to run before an exception is thrown. Use the Throw option when you want to throw an error before a step’s execution. Use Terminate Workflow to shut the workflow down when the task encounters an error.

Advanced UiPath Questions

17. How do you record in UiPath Studio?

There are four recordings available:

  • Basic. It generates a full selector for each activity but has no container. This recording results in slower automation but is suitable for single actions.
  • Citrix. Used for recording virtualized environments, and allows texts, images, and keyboard automation.
  • Desktop. Ideal for multiple actions and desktop apps. The Desktop recording is noticeably faster than Basic. It creates a container where the activities are enclosed.
  • Web. Used for recording web pages and web browsing; it generates a container.

18. Does Blue Prism require coding?

No, it’s code-free.

19. What are the Optical Character Recognition (OCR) engines found in UiPath?

The available OCRs are:

  • Google
  • Abby
  • Microsoft

20. What is the email protocol in UiPath?


21. Name the Orchestrator assets.

The assets are:

  • Text
  • Bool
  • Integer
  • Credential

22. What would you use the UiPath Robotic Enterprise Framework template for?

The template is used:

  • As a starting point for each project
  • As a front office robot source
  • As a queue in Orchestrator

23. How do you validate empty fields in Excel?

You would use row (“ColumnName”).ToString.Equals(String.Empty). This command returns a Boolean value, which validates empty columns in Excel.

24. Explain the role of the package manager in UiPath.

The package manager is a bundle of different elements that aid in automating the process. A package manager is composed of various components, such as frameworks, libraries, wrappers.
