Top 10 UiPath interview questions and answers
UiPath and Blue Prism are the most demanded robotics automation tools used by customers.Third party assessments of the overall capability of two major players in the industry of Robotic Process Automation rate UIPATH and BLUE PRISM, just about equally powerful and competitive, still both are significantly different solutions.Below are the frequently asked top 10 UIPath interview questions and answers.
1). What is delay Activity in UiPath ?
Ans : – UiPath uses the delay activity for making you pause or stop the automation for some time.
This is mainly used in project where you need good timing like waiting and then start of some particular applications or waiting for information loading which you can use in the different activity.
2). What is Element Exists Activities in UiPath ?
Ans :- This activites used to verify if a UI element exists, even if it is not visible.
Exists – Indicates if the element exists or not. The field supports only Boolean variables.
Example : if on page load i want to check if any particular value comes then our work will process . so we will check the div value using Element Exists.
3).Why do you perform Data Scraping in UiPath ?
Ans : Data scraping helps in enabling the extraction of strcutured data,document or application.
Structured data is a group of information that is organized and presented in a predicatable patter.
4). What is selectors and wildcard in uipath ?
Ans : –
Selectors : For automating the specific actions in the user interface, it required to interact with various windows, buttons, drop-down lists and many others. Most applications do this by relying on
the screen position of UI elements, a method that is not at all dependable.
To overcome this problem, UiPath uses what we called selectors.selectors are automatically generated by Studio and do not require further input from you, especially if the apps you are trying to automate have a static user interface.
A selector has the following structure:
WildCard : We use wildcard for replacing zero or multiple characters in a string.These can be quite useful when dealing with dynamically-changing attributes in a selector.
Asterisk (*) – replaces zero or more characters
Question mark (?) – replaces a single character
5). how to import the new Namespaces in UiPath ?
Ans : – Following are the steps for importing the new Namespaces
Step 1 : Open the Imports panel.
Step 2 : In the Enter or Select namespace field, start typing the namespace that is matching with your requirements.Note that suggestions are provided while you type, in case you are not exactly sure what you are looking for.
Step 3 : (Optional) Click the drop-down arrow to view and browse all available namespaces.
Step 4 : select the required namespace. The namespace is added to the Imported Namespaces list.

6). What is Full versus Partial Selectors in UiPath ?
Ans : –
Full selectors : It is used when switching between multiple windows Contain all the elements needed to identify a UI element, including the top-level window generated by the basic recorder
Partial selectors : It is used when performing multiple actions in the same window generated by the desktop recorder activities containing partial selectors are enclosed in a container (Attach Browser or Attach Window) that contains a full selector of the top-level window do not contain information about the top-level window
7). What is Relative Scraping ?
Ans : – Relative Scraping is a technique that enables you to retrieve text from UI elements by using OCR technology. In situations where selectors cannot be found, the target UI objects are identified by using image recognition activities to look for adjacent labels or other elements.
This technique is useful in retrieving text from certain UI elements that are difficult to access by using normal means, such as applications in virtual environments. Using visual labels of UI elements makes up for the inability to find selectors.
8). What is The Assign Activity ?
Ans : The Assign activity is an important activity that is going to be used quite often, as it enables you to assign a value to a variable.
You can use an Assign activity to increment the value of a variable in a loop (see the example in the The Do While Activity chapter), sum up the value of two or more variables and assign the result to another variable (see the example in the Generic Value Variables), assign values to an array (see Array Variables) and so on.
By default, this activity is also included in the Favorites group. To remove it, right-click it and select Remove.
9). What is Type Into UiPath Activities ?
Ans : Type into used for sending keystrokes to a UI element. Special keys are supported and can be selected from the drop-down list.
Text – The text to be written in the specified UI element. Special keys are supported, and you can select them from the activity’s drop-down list.
10). What is Set Text UiPath Activities ?
Ans : – Set Text used for writing a string to the Text attribute of a specified UI element.
Text – The string that is to be written to the Text attribute of a UI element.
