UiPath Interview Questions

The generic variable in UiPath is a sort of variable that can handle a wide range of data types. Arrays, ints, strings, and date formats, for example.

UiPath is a business process automation tool created specifically for enterprise computing. According to industry standards, a wide range of distinctive features and functionalities are available. The following are some features that set UiPath apart from other RPA tools:

• The Entire Package: With the help of three components, UiPath Studio, UiPath Orchestrator, and UiPath Robots, UiPath provides a full solution.
• Intuitive: Because it combines drag and drop and flowchart activities, working with UiPath and developing robots is fairly intuitive. It's also incredibly simple to learn.
• A large number of activities are available in the library: UiPath has a large activity library that includes hundreds of pre-built drag-and-drop activities.
• Security: Because we can store and encrypt credentials on a centralized server, UiPath provides a high level of security.
• Recording: UiPath also has the capability of recording. It contains dedicated recorders for desktop apps, Citrix environments, and terminal emulators, allowing for considerably faster and more exact automation creation.
• Universal Search: It has a universal search capability that allows us to search across all automation resources such as libraries, activities, projects, and workflows in a single search.
• Debugging Techniques: UiPath provides users with a robust debugging tool that is both intuitive and adaptable.
• Collaboration: Because we can save, secure, and exchange scripts in MS Team Foundation and SVN, UiPath encourages collaboration. The workflow can also be reused.
• Integration with third parties: UiPath also offers third-party integration services. At the API level, we may integrate numerous cognitive and OCR technologies from ABBYY, IBM Watson, Google, and Microsoft text analysis.
• Licensing on the Server: Uipath supports server-based licensing, which centralizes and simplifies the licensing procedure.

The three primary components of UiPath are as follows:

• UiPath Studio: It is a graphical user interface (GUI) dashboard for automating workflows. It comes with a variety of tools and settings, making it a one-stop-shop for workflow creation. Each process indicates a certain task to be completed.
• UiPath Robots (also known as bots): They are the most basic component of the UiPath tool. They're primarily used to run automation processes written in UiPath Studio. These robots can also be used to begin the execution of tasks automatically in response to any specified activity on the system.
• UiPath Orchestrator: It is a web-based tool for deploying, scheduling, monitoring, and managing UiPath robots in the environment. It's the centralized platform for managing and controlling software robots. It serves as a link between UiPath Studio and UiPath robots.

The workflow types in UiPath are as follows:

• Sequences: A sequence is a tiny project that works best with linear processes. It makes it simple for developers to go from one activity to another. It can be used as many times as necessary.
• State Machine: A state machine is a machine that uses a specific amount of states to automate the execution time. By activating a specific action, it can be shifted from one state to another.
• Flowchart: A flowchart is a graphical depiction of several automated operations. It's useful for integrating the activities in huge projects and developing complex business tasks. Flowcharts can also aid in the display of many logical operator branching.
• Global Exception Handler: The Exception Handler is intended for use in both small and large automation projects, with the goal of discovering execution problems and, more significantly, deciding the workflow action when they occur. If an execution error occurs while debugging, the Global Exception Handler can be configured to intervene and check the workflow's behavior using the options previously provided in the Exception Handler.

The following are a few of UiPath's most common uses:

• Financial Reporting 
• Extraction of data
• Obtaining Market Information
• Keeping track of the customer dashboard Processing of Data Orders
• Data Capture and Manipulation for Invoice Generation
• Data Entry and Email Exchange
• Getting Data from a Variety of Sources
• Using the System to Automate Daily Routine Tasks

No, Robotic Process Automation is not the same as Artificial Intelligence. While Robotic Process Automation is meant to assist workers by automating repetitive tasks (attended automation), Artificial Intelligence is considered a technology that can replace human labor and automate end-to-end operations (unattended automation). AI uses unstructured inputs and develops its own reasoning, whereas RPA uses organized inputs and logic. A fully autonomous process can be created by combining RPA and artificial intelligence.

Many processes require both RPA and AI to fully automate a process from beginning to end or to improve a robotic process once it has been deployed because companies have both structured data (e.g., form fields) and unstructured data (e.g., free text, natural voice). RPA and AI work together to push automation into new domains, enabling users to automate more and more complicated activities.

Attended bots are bots that work on the same computer as a human user and are typically activated by the user's actions (user events). On these types of Robots, you can't start processes from Orchestrator, and they can't run under a locked screen. They can only be launched from the Robot tray.

Bots that run unattended in virtual environments and can automate a variety of operations are known as unattended bots. This Robot is responsible for remote execution, monitoring, scheduling, and providing assistance for work queues, in addition to the features of the Attended Robot.

The powerful tool UI Explorer allows users to construct a custom selector for a single UI element. It's a standalone utility that users can get from your Automation Cloud instance's Resource Center, or through Studio if you're using UiPath. The UIAutomation.The activities package is added to the project as a dependency.

You don't need to install Studio to use UI Explorer as a standalone application. This is useful when you want to ensure that a program can be automated using selectors. It allows you to quickly inspect items without having to create a process.
The SetupExtensions utility is included in the standalone package, allowing users to install browser extensions and the JavaBridge to examine items across all of the automation needs.

The arguments in UiPath are primarily used when data must be passed from one workflow to another. They are in charge of transferring data between projects. These arguments must follow a particular direction. For instance, in, out.

Robotic Process Automation (RPA) is a technology that allows work to be automated in the same way that a human would. Robotic process automation does not imply that robots would completely replace humans; rather, it refers to computer software that mimics human behaviors.

To put it another way, RPA is a software programme that imitates human activities while interacting with a computer application and automating repetitive and rule-based procedures. Back office activities, data entry, data validation, and other labor-intensive jobs can all be automated with RPA. The method enables businesses to automate their digital processes across multiple applications and systems without having to change their existing IT architecture. RPA can be broken down in the following way:-

• Robotic: A set of codes that mimics human movements and acts like a robot.P
• Process: It is the collection of steps that results in a meaningful activity.
• Automation: It is a procedure that is carried out by software robots without the involvement of humans.

Session variables in UiPath are defined as variables that are unique to a single instance of a process. If many instances of the corresponding process run at the same time, all of the session variables will be the same. The values for those session variables, on the other hand, will be different.

UiPath provides a number of activities that aid in the automation of desktop and web-based applications. In the activity panel under UI automation, properties describe such activities that are utilized for automating apps. ContinueOnError, Delay Before, Delay After, TimeoutMS, Target, and WaitForReady are the core attributes of any project.

• ContinueOnError: This is utilized when we want our automation to keep running even if there is an issue in the activity. The default value is 'False'. When an activity inside the 'try catch' is set to 'True,' the project will not show any errors.
• Delay Before: This command is used to pause the automation before doing a specified task.
• Delay After: This command is used to suspend the automation after completing a certain task.
• TimeoutMS: It's used to locate an element before an error message appears.
• Target: Prior to the start of an activity, the target is used to identify the element.

In UiPath, branching is referred to as the 'condition.' When there is an activity with numerous solutions after a given condition, the branching condition is utilized. This branching allows the software to determine what behavior should be presented in the event that a specific condition is selected.
Switch Activity can be used to implement branching. The integer argument is used by default in the Switch activity, but you may alter it in the Properties panel's TypeArgument list. The Switch activity can be used to sort data into groups based on a specified number of cases.

In UiPath, the flowchart activities allow us to manage the basic settings for any task. These tasks can be used for practically any form of the automation project, regardless of its duration or complexity. Flowcharts are also utilized in the automation of complicated corporate projects to separate and develop logical procedures. During the automation process, flowchart activities can be used to integrate necessary actions or functionalities into flowcharts.

The RPA Lifecycle encompasses several stages of the automation process, from bot creation to bot execution.

The following is a list of them:

• Discovery:  The discovery phase of the RPA lifecycle is the first step. The RPA process architect evaluates the client's needs in this phase. Then it's decided whether or not the procedure can be automated. If the process can be automated, the RPA analyst team may consult with the RPA architect team to assess the process's complexity.
• Solution Design: The steps to automate the process are defined based on the requirements. In conjunction with the process architect, the RPA technical architect creates a Process Definition Document (PDD) that contains information about the entire process. They adhere to the development methodology and devise a plan to automate certain tasks in order to eliminate manual labor as much as possible.
  After all of the requirements have been met, the next stage is to decide on a budget, the number of people who will work on the project, the amount of time that will be spent on it, and so on. The analyst team then constructs a flowchart to visualize the flow of operations, which aids in the selection of the appropriate processes for automation. The RPA tool is used to begin the development of bots and automate tasks after the procedures have been chosen.
• Development: The RPA developer builds scripts/bots to automate tasks using RPA tools at this phase. There are a variety of RPA tools on the market. Following the previously created PDD, automation scripts/bots are generated. There is no demand for coding in most cases. However, depending on the duties to be automated, this may alter.
• User Acceptance Tests: The RPA development team puts the bots they've created to the test in this phase. These bots are put through their paces in a test setting to see how they can help users automate specific chores. If the testing phase is completed successfully, the process moves on to the next level. Furthermore, if the testing fails, it is returned to the development phase, where RPA developers evaluate and correct any issues discovered during the testing phase.
• Deployment and Maintenance: Only when the development and testing phases have been finished are the bots deployed into the production environment. Users can utilize them to automate their tasks when the deployment procedure is completed. If a problem with the bots persists, such as bots that do not automate, they are forwarded to the RPA development and testing team. The bots will be analyzed again by the development team, and the issues will be resolved.
• Bots Execution: After the bots have been deployed, this phase includes the bots' execution. Bots are also examined to guarantee that the implementation is carried out correctly.

A FlowSwitch activity is similar to a FlowDecision, but it is not limited to a True or False branch. A FlowStep is a name for each branch of a FlowSwitch activity.
When more than two alternative branches are required, the FlowSwitch activity is a conditional node that provides branching for the flow of control depending on a match condition. We use the FlowDecision activity instead if the flow branching only requires two pathways.
When the Expression in the FlowSwitch<System.int32> activity is evaluated, it returns a value of type Int32. The activity additionally includes a set of Cases that define a unique mapping between the evaluation's possible outcomes to a set of FlowNode objects. The FlowNode that is executed is the one whose int32 object matches the evaluated Expression's value. For the case where no match is found, a default case might be specified (optionally).

In UiPath, the switch activity is used to transition from one value to another based on the expression's defined values. As a default, it uses the switch integer argument. However, by navigating to the properties tab and selecting the needed Type of Argument, we can easily change it (TypeArgument). The activity is most useful when it comes to categorizing data by case number. This activity can be used to save data into different spreadsheets or to sort through a list of user names, for example.

Yes, UiPath allows us to automatically record the actions and activities we execute on the system. We can quickly personalize the project using the automatic recording tool, which provides a number of possibilities. It creates a skeleton of the entire procedure that has been completed. Instead of manually automating the entire project, we can quickly parameterize and personalize the process, which saves a lot of time.

Wildcards are symbols that, similar to SQL, allow you to substitute 0/more characters in a string. They're usually employed when a selector's attributes are changing dynamically.

The following are used as wildcards:
Asterisk (*) - can be used to replace one or more characters.
Question Mark (?) - A single character is replaced by a question mark (?).
In the form of an XML fragment, selectors are used to store the characteristics of a GUI element and its parents.

The following recording options are available in UiPath:

• Basic: Basic recording is primarily utilized for single activities because it generates a full selection for each one.
• Desktop: Desktop recording is mostly utilized for all types of desktop programmes because it generates container activities and partial selections for each contained activity.
• Web: This option is usually used in web programmes and browsers to record. This is due to the fact that it generates container activities by default, which use the Simulate Type/Click input technique.
• Image: This recording option is ideally suited for virtualized systems like Citrix, SAP, VNC, and virtual machines (VMs). It is, however, limited to text, keyboard, and image automation only.
• Native Citrix: It is meant for Citrix-virtualized desktops and apps.
• Computer Vision: It may be used to automate the design of computer vision-based workflows.

In UiPath, the assign activity is mostly used to assign values to variables. When we wish to alter the value of a variable, we usually use this action. This activity also comes in handy when we need to add a loop to our project. For instance, in the loop, incrementing the value of a variable. By default, the activity is included in the Favorites group. Using the 'Right-click' and then 'Remove' options, we can easily remove it.

We have two alternatives when it comes to assigning activities:

• We can store values in the existing variable after adding the value.
• We can store values in any other array after adding the value.

 The distinction between a chatbot and an RPA engine is comparable to that between a mouse and a mammoth. 

ChatBot - A bot that is programmed to converse with a user (human) in a human-like manner. Make a request and advise backend systems to offer a request, or recommend a pre-learned remedy to a specific problem the user is experiencing.
RPA (Robotic Process Automation) - It is a bot that is programmed to automate a manual business process such as performing a job or activity inside a business function. HR, Finance, and Procurement are examples of business functions. A chatbot can be used to supply data into an RPA engine, but it cannot replace the RPA engine's functions.

Following are the differences between Traditional Automation and Robotic Process Automation:

• Traditional IT automation takes a long time and involves a lot of labour, time, effort, and money.
• RPA is a quick fix for generating improvements right away.
• Traditional automation and RPA both require sound strategy and preparation, but RPA is easier to implement.
• While both strive for the same goal of automation, RPA is more efficient, better, and less expensive than classical automation. As a result, traditional automation is a strategic decision, while RPA is a tactical decision.
• In short, if you have the luxury of time and money, classical automation is the way to go. If you're pressed for time or money in your business, RPA is the way to go.

Thin clients: A thin client is a computer system that operates on a server. They operate by connecting to a distant server-based environment, which stores the majority of apps and data. The majority of the tasks, such as computations and calculations, are handled by the server. When it comes to security threats, they are more secure than thick client systems. Because there are centralised servers in thin clients, system management is considerably easier. With the help of centralization, hardware may be optimised, and software maintenance is significantly easy.
Thick clients: A thick client is a system that can connect to the server even if it is not connected to the internet. Clients who are overweight are referred to as "heavy" or "fat." Thick clients aren't reliant on the server's apps. They have their own software programmes and operating system. They have a lot of flexibility as well as a lot of server capacity. Thick clients are more vulnerable to security risks than thin clients.

Yes, it can run the same process in two robots at the same time if each system is registered as a separate robot. On a machine running the Windows Server operating system:

• All Robots can perform the same process at the same time; 
• All Robots can perform the different processes at the same time; 

They are often referred to as high-density robots.

The practice of dealing with or addressing problems observed in various UiPath tasks is known as exception handling.

The following are the main options for managing exceptions:

• Rethrow: When we wish to conduct actions before an exception is thrown, we use rethrow.
• Terminate Workflow: It is used when a job finds an issue and we want to stop the entire workflow from running.
• Throw: When we wish to throw an error before performing any action, we use this method.
• Try Catch: It is mostly used to deal with exceptions. The try block contains a list of activities that may fail during execution. Furthermore, the tasks to be performed once an exception occurs are contained within the catch block.

If the return on investment (ROI) is better than installing RPA, one should favor system integration. However, that circumstance will appear in only a few projects.

If one works in a local area and uses similar platforms/software, they should consider integrating your systems. System integration will almost certainly necessitate full access to the back-end scripts, and the deployment duration will almost certainly be longer than RPA. If one works in back-office operations, one may notice that different platforms, such as legacy, GUI, and web-based, are all utilized in tandem. System integration becomes more complicated as a result of this.
RPA software, on the other hand, is platform agnostic. They might also be configured from the front end on any platform. RPA developers are easier to train or find, and the schedule is shorter. As a result, using RPA is a better option.

UiPath creates log files by default, which track Studio and Robot activities. The Open Logs button on the Execute ribbon tab can be used to access these logs.
More information on automation is required for difficult issues. Tracing must be enabled in order to collect them.
Tracing in UiPath Studio produces an .etl file. It is used to log high-frequency events when tracking the performance of an operating system and contains binary log data at the trace level, such as disk accesses or page faults.

Mainframe Applications:

• It's a single-screen application with a keyboard interface.
• Blue Prism has a different set of in-built commands dedicated to mainframe applications.

Non-Mainframe Applications:

• It includes more than one screen.
• Control is passed from one screen to the next.

Selenium is built primarily for testing web applications and web pages; it is impossible to interact with numerous applications in selenium and use one application's result as an input for another. It is completely incompatible with virtual environments such as Citrix and others. While UiPath is an RPA solution that can be used to automate any existing software process and replace any activity that can be done by a human.

As a result, we can argue that RPA is the next step in the evolution of existing automation systems. It enables anyone with little or no software programming experience to create a complicated rules-based procedure. You can use UiPath to perform whatever that Selenium can do, but vice versa is not possible.

RPA developers should use one of the following methods to address runtime exceptions in the workflows:

• By keeping track of any exceptions that occur.
• Inside the Catch blocks, employing automatic recovery sequences.
• When executing external workflow files, try/catch blocks are used.

Citrix Technology is used to automate virtual computers. Consider a situation in which you need to connect to a server from your PC. When you try to access thserver now, you don't receive the main server; instead, you get a picture of the server's screen. Now, anytime you click on something, the corresponding image or pixel is delivered to the server. Then it is precisely clicked over there in the server. Citrix technology and UiPath can be used to automate these kinds of processes. With the use of recorders, UiPath attempts to deliver this automation.

Processes- The Processes page allows users to create new processes, manage current processes, and build new processes from uploaded packages, as well as maintain all of your processes up to date with the latest package versions.

Queues are a form of storage container that may hold an infinite number of objects. Queue objects can be used to store a variety of data, such as invoices or client information. Other systems, such as SAP or Salesforce, are used to process this data.

Jobs- A job is a description of how a procedure is carried out on an UiPath Robot. It has the ability to start a job in either attended or unattended mode.

Assets are variables or credentials that are regularly shared and can be used in various automation programmes. They let users store one-of-a-kind information that robots can access fast.

• Excel Automation: For sorting, removing, retrieving, and analyzing data, UiPath is a useful tool. Data migration and integration into platforms are straightforward. StudioX has a strong Microsoft Excel interface and comes with various activities that automate Excel chores.
• File Automation: It refers to the automation of file and folder-related actions on your computer, such as creating, renaming, and copying files and folders. StudioX comes with a number of activities that help you automate actions involving files and folders.
• CSV Automation: It is used to attach data to CSV files or to get data from them. Add the CSV actions to the Use Excel File activity, which defines the Excel file that will be used to transport data from CSV to Excel.
• Mail Automation: Task automation is possible with emails from Outlook desktop, Gmail, and Outlook 365. By using Outlook 365, Gmail, or the "Use Desktop Outlook App" action, users can create activities that use data from the account inside the resource activity.
• Word Automation: The most typical tasks in Word documents may be automated using Word automation.
• PowerPoint Automation: This allows the user to automate some of the most popular PowerPoint actions. Add a ‘Use PowerPoint Presentation' action to the presentation, and then add the Presentation activities to automate inside Use PowerPoint Presentation.

Conclusion:

The RPA tool UiPath is well-known. Its popularity has expanded over time, and it is now used by organizations all around the world. UiPath helps firms automate their business operations by allowing IT teams to set up software robots that collect and evaluate data in a range of applications. People that learn UiPath will have a lot of opportunities in the future.

Robotic Process Automation (RPA) is a software robot that can do tasks similar to those performed by humans. These software robots are designed and deployed using RPA techniques. These tools use pre-defined activities and business rules to execute a set of tasks, transactions, and processes across multiple software platforms autonomously. RPA can achieve the required outcome without the need for human intervention.

Test Automation is a software testing process that employs specialized tools to manage the execution of tests. It also compares the actual results to the ones expected. Test automation is carried out automatically, with little or no involvement from the test engineer. It's a key stage in the development process for adding more testing that's tough to do manually.

The UiPath architecture is made up of three layers, including:

Client Layer: This layer comprises UiPath components that users can interact with. UiPath Studio, UiPath Agent, Robots, Browsers, and Executors are some of the examples. These components can be used to build and develop automation tasks. UiPath bots then carry out the tasks that have been created. The layer is sometimes referred to as the presentation layer.

Server Layer: This layer displays all of the server-related information. The UiPath Orchestrator is located on this tier. The full project is published to the server once the UiPath bots have been constructed and can execute tasks without issues. The project can be easily executed on several platforms thanks to an Orchestrator. The Orchestrator is in charge of the entire project and assists us in meeting service levels and schedules.

Persistence Layer: Database servers make up the majority of the persistency layer. The layer is used to hold UiPath bot configuration information. It also organizes and regulates queues, as well as the tasks currently in them.
Data from different users, logging information, associated robots, assigned tasks, asset details, and so on are all included in the configuration details. Users often enter the needed details in the Orchestrator.

UiPath is simple to use and features drag-and-drop activity functionality, so you can learn it without paying for a course or tutor. The best thing is that UiPath provides a Community Edition that is free for life and includes most of the features of the Studio version. It's a lot easier to learn than programming because it comes with a lot of helpful tools and GUI components, as well as active forums and a lot of training information.

RPA is a fantastic career choice since more and more firms are turning to automation to save money, and they can't find enough employees with good RPA abilities to fill their positions. As a result, RPA salaries have risen faster than those in other IT disciplines.

Yes, RPA is worth learning. First of all, RPA can replace 5 to 10 human workers, resulting in a higher return on investment. Secondly, RPA automates dull and repetitive operations, freeing up human workers to focus on more productive and revenue-generating duties. Thirdly, RPA is more accurate and has a better throughput than human workers.

No, RPA is not a hype. RPA is the fastest-growing section of the global enterprise software market, with projections predicting that 85%t of large and very large companies will use it in some way. They anticipate that RPA expanded by 63% to $846 million in 2018, with the three major providers expanding by more than 40%.
