Beginner Level UiPath Interview Questions

What is UiPath? 

Ans: UiPath is a robotic process that provides end-to-end solutions to large businesses in converting their repetitive tasks into an automated process by using various tools and techniques.  It is an RPA (Robotic Process Automation) tool used in large-scale businesses to automate their repetitive work. 

What are the workflows in UiPath?

It offers various workflows. When you are developing a workflow file, UiPath gives four diagrams for joining activities into a working structure. 

  • Flowchart: These are best suited for showcasing decisions within a process. 
     
  • Sequence: This process helps the developer to move from one activity to another easily and can be used multiple times. 
     
  • State Machine: It is a complex process that can be called a flowchart with arrows which is used in high-level processes with multiple transactional histories. 
     
  • Global Exception Handler: These are used to determine errors in the workflow and are used in both small and big transaction projects. 

How does Uipath help in File Comparison?

When you are working with multiple .xaml files in the same project, comparison between two files becomes easier with UiPath. UiPath studio has a feature called compare files that help in comparing two similar files. It helps to see the changes made in the current workflow file and not disturb the original file. Another feature is file diff when comparing between different versioned workflows. Changes between the original file and the versioned in GIT, SVN, or TFS can be made using this feature. 

Discuss the features of UiPath.

With the help of the OCR feature, UiPath comes with a lot of features. Some of the most useful features of UiPath is listed below: 

  • Security and robustness 
     
  • Recording and Playback
     
  • Drag and Drop
     
  • Advanced Scrapping options

What is the UiPath tool?

UiPath is a robotic automation processing tool that is used in large-scale end-to-end automation processes. The tool helps to convert monotonous tasks into an automated process. It offers various software tools and techniques to convert this and help businesses save time and accelerate their businesses. 

7. What are Selectors and Wildcards in UiPath?

Wildcards are used when you want to replace zero or multiple characters in a string. These are very similar to SQL, In a selector, when you are working with dynamically changing attributes, these wildcards are widely used. Some used wildcards are: 

  • Asterisk (*): - Used to replace one or more characters. 
     
  • Question mark(?): - Used to replace only one character. 
     
  • Asterisk and Question Mark:- Match an attribute value with at least one character. 

What is a UiPath Robot?

The processes designed in UiPath are executed by the UiPath Robot. It acts as an execution host for those processes, and its primary usage is to run these processes that are written in the UiPath studio. Robot(Orchestrator Object) defines its privileges and capabilities that include access to folder resources, credentials, etc. 

What is debugging in UiPath? 

Debugging is a process that is used for identifying and resolving errors in the application. Any issues that hinder the project functionality. It has both the functionality of breakpoints and logging, that helps in the easy identification of errors. Logging helps to see the progress of the project, and by default, debugging is done on the local robot. To get it done on a remote machine through robot enable, remote debugging. 

What are the Different Components in UiPath?

There are various components in UiPath. The client layer comprises these components that help users interact with UiPath.C Some of them are UiPath studio, Uipath Robots, UiPath Agents, UiPath Orchestrator, executor, and many more. 

Medium-Level Interview Questions 

What is the difference between UiPath and Blue Prism?

Parameters UiPath Blue Prism 
Debugging Debugging in UiPath is more challenging and difficult.  Blue Prism gives you the ability to interact dynamically with variables and scenarios to debug errors. 
Installation Installing UiPath Studio is more time-consuming.  Blue Prism is easy to install and does not consume much time. 
Features  UiPath offers the best visual design features.UiPath offers the best visual design features. Blue Prism offers the best control features. 
Accessibility It is available on both mobile and desktop devices.  It only has access limited to desktops.
Flow Capture The Macro Reading feature is enabled. Blue Prism does not support macro reading.
Programming languages  Visual basics like HTML, CSS, and VBScript are used in UiPath.  C# is generally used as a programming language. 
Source Control Built-in control options are available, but git and bitbucket files cannot be used simultaneously for comparison.  Two different versions of the file can be compared using blue prism. 

What is delay activity in UiPath?

To pause or stop the automation activity for some time, a delay activity is performed. Generally, it is used on activities that require good timing to start, such as activities that wait for the application to start or on the activities that process the information from different activities and then the next activity that uses this information to process. The duration is provided in hh:mm:ss. 

What are the different properties of UiPath?

UiPath provides users with various properties that help in the automation tasks for web and desktop-based applications. Under UI automation, activity panel properties give information on those activities that can be utilized for automating apps. 
These properties are 

  1. DelayBefore
     
  2. DelayAfter
     
  3. ContinueOnError 
     
  4. Target
     
  5. WaitForReady 

All these properties are utilized in the automation processes.  

Where are the major applications of UiPath?

UiPath can be used in various scenarios and has many use cases. Some of the major applications of UiPath are listed below: 

  • Healthcare
     
  • Banking 
     
  • Insurance
     
  • Extraction of data 
     
  • Financial Reporting 
     
  • Email exchange and data entry 
     
  • Workflow drag and drop

What do you mean by session variables in the context of UiPath?

Session variables is a reference to the single process running in the instance. This is a unique value for a single process. In case, there are many instances corresponding to the same process running at a single time, the session variables will remain the same but with different values. 

What is switch activity in UiPath? 

Switch activity allows you to switch between one or another value based on the expression’s defined values. Switch Activity in default, uses an integer argument, but however you can change it by navigating to the properties tab and selecting the desired argument. When you want to categorize data based on the numbers, switch activity is the most useful among all. 

Explain in detail the life cycle of RPA.

Robotic Process Automation (RPA) is a process that automates the process for a business without human interference. The life cycle of RPA is discussed below: 

  1. Identify and Analyze
     
  2. Design and Development
     
  3. Testing 
     
  4. Implementation 
     
  5. Deployment and Maintenance
life cycle of RPA.
  • Identify and Analyze: This is the first stage in the RPA cycle. This is to identify the business process which needs to be automated. Later, it is analyzed by the architects to find the process by which automation for the tasks can be done. 
     
  • Design and Development: After the process is analyzed, architects create a PDD, i.e. (process definition document), which thoroughly discusses the design and how the development will take place. A flow chart is designed, which is then converted into a bot with the help of a tool. 
     
  • Testing: After the development is done, it then comes in the testing phase, in which it is tested to see whether it satisfies all the requirements. Testing is done on various scenarios and can be done by the development team or testing team. 
     
  • Deployment and Maintenance: The last stage is to deploy and maintain the process. If any issues are encountered, it is again sent back to the previous stages. 

What is the difference between UiPath and Automation Anywhere?

UiPath Automation Anywhere
Follows traditional workflow model i.e. maintaining flowcharts and a sequence for the tasks.  Based on a task-based model, i.e., can interact with each other.
Using UiPath is budget-friendly.  Automated Anywhere has a high-cost deployment. 
It is a cloud-based architecture.  It is a client-server-based architecture. 
UiPath has more frameworks and sets which are difficult to understand.  Automation Anywhere is easy to use. 
Accessibility to both mobile and desktop is available.  Accessibility is limited to desktops only. 
UiPath uses the UiPath orchestrator as its proprietary language.  Automation Anywhere supports JavaScript, and VBScript, which is easy for the programmers to understand and give their inputs. 

What is the difference between UiPath and Selenium?

Usage

  • Selenium is generally used in the testing of web applications and web pages. 
     
  • UiPath is a RPA tool that is used to automate the process. 

Programming language

  • To work with Selenium, it is important to have knowledge of Java programming language. 
     
  • UiPath is easy to learn. It does not require any previous knowledge of programming language. 

Environment Support

  • UiPath has a free and paid version available for the software. 

What are the ways to create Variables in UiPath?

There are generally three ways to create a variable in UiPath. 

  1. Applying the variable tab available in the control bar. 
     
  2. Select the Create Variable option inside the ribbon tab. 
     
  3. Using the output column and Properties window. 

Advanced Level Interview 

What is the difference between data scraping and screen scraping?

Data Scraping Web Scraping
It is mostly used to extract structural data.  Web scraping is used to extract non-structural data. 
Data Scraping stores the scraped information in a data table.  It stores the scraped information inside a string. 
Data can be easily extracted from Excel or DB.  Extraction of data from these sources is difficult. 
Data collection from PDFs and images is not possible.  Data collection from PDFs and images is possible. 

What are variable error-handling activities available in UiPath?

Error handling activities refer to the exception handling in the UiPath. These errors are well handled by the UiPath through these options. The possible ways to handle errors in UiPath are by using Try Catch, Throw, Terminate Workflow, and catch.  

  • Try Catch is used when you know your program can throw an error. With the use of try-catch, errors can be displayed, and the rest of the execution continues. There can be multiple catches for a single try block.
     
  • Throw: To specify the type of exception throw is used. When you know the error and want to display it, the keyword plays a pivotal role. 
     
  • Terminate Workflow: To forcefully stop an activity from performing, terminate workflow is used. It is important that your robot is connected to Orchestrator for explicitly stopping an activity from performing. 
     
  • Catch:  Catch is used to catch errors inside the try block. There can be multiple catch blocks inside a single try-catch block. 

 Differentiate between RPA and Test Automation.

RPA Test Automation
RPA is used in the automation of business processes.  Test automation is used to automate repetitive test cases. 
Programming knowledge is not required as it provides drag-and-drop features.  To perform test automation, it is important to have knowledge of at least one programming language. 
All the users inside the team can perform RPA. Only developers and testers in the team can perform the test automation. 
Human work is minimized.  Helps in reducing the execution time. 
RPA can perform multiple tasks like data entry, form filling, loan processing, etc.  Only test cases can be automated by using test automation. 
Work as a virtual workforce.  Work as a virtual assistant. 
Examples: Blue Prism, UiPath, Automation Anywhere Examples: Selenium, Jira, etc. 

Why the term assign activity is used in UiPath?

Assign activity in UiPath is used to assign values to the variable. To implement a loop in your project, assign activity helps to assign a value to the variable so that the variable can be used in the loops. Also, it is generally used to change the value of a variable. Generally, there are two ways of using assigned activity. 

  1. Incrementing the value, and assigning it back to the existing variable. 
     
  2. Incrementing the value and assigning it to a new variable. 

Explain UiPath architecture.

UiPath architecture is mainly composed of three main UiPath components: 

  1. UiPath Studio
     
  2. Robot 
     
  3. Uipath Orchestrator UiPath Studio: This is the GUI dashboard through which the automation workflow is developed. 

Robot: To automate the process as described, the robot helps in the execution of predefined tasks. 

UiPath Orchestrator: The UiPath Orchestrator acts as an interface between UiPath studio and Robot. It manages all the automated tasks. 

Uipath Architecture has three layers:

Three layers are : 

  1. Presentation Layer: This is the client layer through which the user interacts. It is made up of UiPath components that users can access. 
     
  2. Server Layer:  The server layer displays all the information related to the servers. The UiPath orchestrator is the top-tier component for this layer. All the schedules and services are hosted through the orchestrator. 
     
  3. Persistence Layer: The majority of the persistence layer is composed of database information. All the information related to user login, credentials, associated robots, and task schedules are maintained in this layer. Most of the time, the user needs to enter the required details in the orchestrator. 

Give a brief description of Process, Job, Asset, and Queue in UiPath.

  • Processes: The processes page allows users to create new processes, manage current processes, and update the process from the update package. It also allows you to maintain all your processes up to date with the latest package version. 
     
  • Job: In a UiPath, the description of how the process is to be carried out is described in the job. It has the ability to start the process in both modes, i.e., unattended and attended modes. 
     
  • Asset: These are more like variables that help to store the values and credentials that are regularly shared in the automation process. One of the kinds of information can be stored by users so that robots can access it faster. 
     
  • Queue: A storage container that can store an infinite number of objects. A variety of information, like client information, and invoices, can be stored. Systems such as Salesforce and SAP are used to process this data. 

Explain the steps to create and execute a project in UiPath Studio.

To create a project in UiPath Studio, follow these steps: 

  1. Click on Start in UiPath studio software. 
     
  2. The next is to select the project type. 
     
  3. This will open a new tab in which enter the asked information, such as name, description, and location, and click on create. 
     
  4. In the design window, drag and drop the required activities. 
     
  5. Click on F5 or press enter. 

The new project is created in UiPath studio. 

What is Packaging in UiPath?

Projects are displayed on the packages page in the orchestrator field. Packaging is used to archive and send automation automation packages to software tools so that these packages can be run. Distribution of these packages to the connected robots can be done, and each robot can be assigned to a specific package in the environment. In case, it is not connected to the orchestrator, packages get stored locally in the UiPath studio feed. 

Differentiate between thin and thick clients. 

Thin clients Thick clients
Installation is done through a web browser. Installation of thick clients is done locally. 
Thin clients are more accessible to deploy.  Deploying thick clients is difficult and expensive. 
Constant communication with the server is done.  Communication with the server happens at predetermined intervals. 
The server handles all the processing performed in thin clients.  Computer resources are more utilized in thick clients. 
Data verification is required from the server end. Data verification is performed on the client side. 
Thin clients are generally used by handheld devices.  Customization systems generally use thick clients. 

What are the different types of recording available in UiPath?

There are five types of recording available in UiPath. 

  1. Basic recording: In this, a full selector for each activity is assigned with no container. Because of this, the automation process is generally slower. Activities like checking a checkbox, and opening and closing of the application are done using basic recording. 
     
  2. Desktop recording: Faster than basic recording, it generates a container, in which activities are enclosed and a partial selector for each activity is assigned. Suitable to perform desktop app activities and multiple actions and activities. 
     
  3. Web Recording: As the name suggests, it is used to perform recording on browsers and web apps. By default, it uses a simulated Type/Clicks input method and generates a container for performing activities. 
     
  4. Image recording: It supports manual recording like a single action. Also, allows only image, text, and keyboard automation and requires explicit positioning. Generally used to record virtual environments like VNC, Citrix, and virtual machines. 
     
  5. Native Citrix: Similar to desktop recording, but can only be performed on Citrix environments. It enables you to record multiple actions performed on the screen.
