When you want to categorize data based on the numbers, switch activity is the most useful among all.
17. 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:
Identify and Analyze
Design and Development
Testing
Implementation
Deployment and Maintenance
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.

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.
23. Differentiate between RPA and Test Automation.

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.
Incrementing the value, and assigning it back to the existing variable.
Incrementing the value and assigning it to a new variable.
25. Explain UiPath architecture.
UiPath architecture is mainly composed of three main UiPath components:
UiPath Studio
Robot
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 :
Presentation Layer: This is the client layer through which the user interacts. It is made up of UiPath components that users can access.
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.
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.
26. 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.
27. Explain the steps to create and execute a project in UiPath Studio.
To create a project in UiPath Studio, follow these steps:
Click on Start in UiPath studio software.
The next is to select the project type.
This will open a new tab in which enter the asked information, such as name, description, and location, and click on create.
In the design window, drag and drop the required activities.
Click on F5 or press enter.
The new project is created in UiPath studio.
28. 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.
29. 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.
30. What are the different types of recording available in UiPath?
There are five types of recording available in UiPath.
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.
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.
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.
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.
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.
UiPath Scenario-Based Interview Questions
31. How would you handle an automation process where a web application crashes frequently?
Answer: In such a scenario, the automation process should be designed to handle exceptions gracefully. I would use the following approach:
Try-Catch: Enclose the automation steps related to the web application in a Try-Catch block. In case the application crashes, the exception will be caught and handled.
Retry Scope: Implement a Retry Scope activity to attempt the action multiple times before throwing an error. This can handle intermittent crashes.
Application Restart: Include logic to restart the web application when it crashes. The Kill Process activity can be used to close the application, followed by the Start Process activity to reopen it.
Logging and Notifications: Log the issue and notify the appropriate team if crashes persist beyond a certain limit, enabling them to investigate further.
32. How would you automate data extraction from a dynamically changing table on a web page?
Answer: For automating data extraction from a dynamically changing table, I would take the following steps:
Data Scraping: Use UiPath's built-in Data Scraping wizard, which is capable of extracting structured data from tables, even if the table’s content changes dynamically.
Selector Optimization: Ensure that the selectors used for the table are dynamic and robust. Use wildcard characters and anchor elements to make the selectors more reliable across different table states.
Wait/Delay Mechanism: Implement a mechanism (e.g., Element Exists or On Element Appear) to wait until the table is fully loaded before attempting to scrape the data.
Pagination Handling: If the table spans multiple pages, incorporate logic to handle pagination, ensuring that data from all pages is captured.
33. How would you automate a process that requires different user credentials at different stages?
Answer: For automating a process with different user credentials, I would do the following:
Orchestrator Assets: Store the credentials for different users in UiPath Orchestrator as Assets. This allows secure access and management of credentials during the automation process.
Get Credentials Activity: Use the Get Credentials activity to fetch the appropriate credentials from the Orchestrator at each stage of the process.
Credentials as Variables: Store the credentials as variables in the workflow and pass them to the required steps when performing login operations at different stages.
Role-based Automation: If the credentials correspond to different roles (e.g., admin, user), design the workflow to switch roles dynamically based on the required stage of automation.
34. How would you manage a scenario where multiple bots need to work on the same task but on different data sets simultaneously?
Answer: To manage such a scenario, I would use the following approach:
Queue in Orchestrator: Utilize UiPath Orchestrator queues to distribute data sets. Each bot will fetch a unique data item from the queue and process it independently.
Transaction Items: Divide the task into multiple transaction items and add them to the queue. Each bot picks up a transaction item, processes it, and moves to the next available one.
Parallel Processing: Configure multiple bots to work in parallel, allowing them to process different data sets simultaneously while maintaining efficiency.
Logging and Monitoring: Implement logging for each bot’s actions and monitor the progress in Orchestrator to ensure that each bot is working on a separate dataset without conflicts.
35. How would you handle an automation process that requires approvals from different departments?
Answer: For automating a process that involves multiple approvals, I would follow these steps:
State Machine: Use a state machine workflow to model the approval process, where each state represents a different approval step.
Wait for Response: After sending the approval request, use activities like Wait for Form Task or Wait for Email to pause the process until the approval is received.
Parallel For Each: If approvals can be gathered simultaneously from different departments, use the Parallel For Each activity to handle multiple approvals in parallel.
Decision Logic: Implement decision logic (using If or Switch activities) to move forward in the process based on the type of approval received (e.g., approval, rejection, or escalation).
Orchestrator Action Center: If using UiPath Orchestrator, leverage the Action Center to manage and track human approvals across departments, ensuring that approvals are processed in sequence or parallel, as required.
