Infosys Interview Questions and Answers for 2025

A class encapsulates variables of various types and functions that may be combined. 

As an example, 

Class All variables and techniques connected to a student, such as name, roll number, marks, subjects chosen, and so on, can be used. When an application needs the details of a Student, an object of this class may be constructed to retrieve all of the student's information. 

Student student1 = new Student(); 

Only nested classes in Java can be static. A static top level (outer) class is not possible. 

public class Outer { 
public static class Nested { 
} 
} 

 Yes, a static class object may be generated directly in another class without generating an instance of the outer class. 

public class Test { 
Outer.Nested obj = new Outer.Nested(); 
} 

Joins are used to retrieve information from many tables by utilizing the main and foreign keys of the associated tables. As an example, 

To find out what books a student has read, we can simply type a query like - 

select from student, book student.student name, student.student batch, book.book title, book.book author where student.student id=book.student id; 

The end outcome will be - 

The Pugh Matrix is used to determine the best and alternate options. This approach is now an integral element of the Six Sigma methodology. It is also known as a problem /design matrix. This is commonly asked to students appearing in Infosys business analyst interview questions.

• BPMN is an abbreviation for Business Process Model and Notation. It represents business processes graphically. 
• BPMN Gateway is a component of processing modeling that is used to govern the flow of interaction and the sequence of operations. 
• Flow Objects, Data, Connecting Objects, Swimlanes, and Artifacts are the five core element categories in BPMN. 

Yes, Kano Analysis was used in one of my previous jobs. Kano Analysis is used to assess the impact of a system on customer satisfaction by analyzing it in terms of its requirements. 

Kano Analysis is divided into three sections: Unexpected Delighters, Performance Attributes, and Must-Have Attributes. 

A staple in Infosys interview questions with answers, be prepared to answer this one.

Yes, I would recommend drawing two separate diagrams. The first is a use-case, and the second is an actor diagram. So that we can highlight all possible activities in a use case and in an actor diagram, and then combine both diagrams to create an effective use-case diagram. 

The pair-Choice Technique is used to prioritize different items in a process. It is mostly used when there are multiple stakeholders involved in the project. The group is asked to compare each item to others and choose the one with the highest priority. 

• It is an abbreviation for Software Engineering Body of Knowledge. 
• GAP Analysis is the process of comparing and differentiating two things or processes. 
• As a business analyst, I would create a document that clearly states that no changes will be accepted after a certain period of time and have the user sign it. 

Use-case points are used to calculate the cost of developing the system. 

PEST (an acronym) for Political, Economic, Social, and Technological. It is used to assess the business environment in which it must function. 

JAD is an abbreviation for Joint Application Development. 

Extraction, Transformation, and Load (ETL) is a data processing method that is primarily used in data warehousing. 

Eliciting requirements assists you in gathering information from users and stakeholders. It is beneficial to understand what people expect from a system. It also includes several tactics that work directly with users or clients. 

Configuration management includes version control. In comparison to configuration management, which manages individual components, it is primarily concerned with the processing of changes emerging from the prior document. 

Problem-solving abilities, as well as management and communication abilities 

IT knowledge and elicitation skills are all required in a good business analyst 

Being a business analyst, Scope creep may be avoided by using the following technique: 

• Documenting the project's scope. 
• By employing suitable change management techniques. 
• Before implementing a change, notify the impacted parties of the consequences. 
• Adding additional requirements to the project log. 

A project that included a series of actions from beginning to end. A crucial route is a combination of actions that encompasses the project's longest path. 

Rational Unified Process (RUP) is an approach for improving product applications. It is an object-oriented strategy that is used to ensure effective project management and high-quality software creation. 

The project deliverables are a set of measurable products and services that are supplied to the end customer as an output at the end of the project. 

Previously, web developers utilized VanillaJS and jQuery to create dynamic websites, but as the logic of a website expanded, the code became increasingly difficult to maintain. For apps that employ complicated logic, developers have to work extra hard to keep the app's separation of concerns. Furtherly, jQuery did not  give data management facility across views. 

Client-side frameworks such as Angular came into play to address the aforementioned issues, making life easier for developers by managing the separation of responsibilities and separating code into bits of info (In Angular, called Components). 

Client-side frameworks enable the creation of complex web apps such as Single-Page-Application. Not that we can't build SPAs using VanillaJS, but doing so slows down the development process. These specific business analyst Infosys interview questions for fresher and experienced are asked many times. 

While the DOM is the accepted standard method for traversing an HTML element tree, XPath is the navigation tool used to identify a web element based on its XML path. 

XML, which stands for 'Extensible Markup Language,' is a data storage, organization, and transfer protocol. It holds data as a key-value pair, which is comparable to HTML tags. Because they are both markup languages and come under the same umbrella, XPath and HTML may be used to locate elements. 

The basic idea behind identifying elements with XPath is to traverse between numerous elements throughout the full page, allowing a user to discover an element by referencing another element. 

Single slash (/): A single slash is used to create an absolute path in an XPath. In this scenario, the XPath would begin selection at the start node of the document. 

The double slash (//) character is used to build an XPath with a relative path. In this scenario, the XPath would begin selecting wherever in the document. 

Yes, selenium has several drawbacks: 

• Selenium can solely be dedicated to test web applications. 
• It is not feasible to test mobile or desktop applications. 
• Selenium cannot test captcha and barcode readers. 
• To create reports, a third-party tool such as TestNG or JUnit should be utilized. 
• Because Selenium is a free technology, there is no ready vendor support to assist users locate various helpful groups. 
• Users are assumed to have prior programming language experience. 

The original version of Selenium featured only three tool sets: Selenium IDE, Selenium RC, and Selenium Grid. The initial version did not have a WebDriver. Selenium WebDriver was later introduced and so included in Selenium V2. However, since the inclusion of WebDriver, the usage of Selenium RC has been discouraged and is no longer widely used. Selenium 3 is currently in use. Selenium functionality such as IDE and WebDriver have just been introduced. The most recent version is Selenium 4.

Selenium is more commonly used than QTP because: 

• Selenium is a free and open-source tool, whereas QTP is a paid tool. 
• Selenium is used exclusively for testing web-based applications, although QTP may also be used to test client-server applications. 
• Selenium works with a variety of browsers, including Firefox, Internet Explorer, Opera, and Safari, as well as operating systems. Windows, Mac, Linux, and other operating systems are supported by Selenium. QTP, on the other hand, is restricted to Internet Explorer on Windows. 
• Selenium provides the interoperability of several programming languages. Python, Ruby, Perl, and more programming languages are supported by Selenium. However, QTP only supports VBScript. 

• getwindowhandles(): Its return data type is SetString>, and it is used to obtain the addresses of all open browsers. 
• getwindowhandle(): It is used to obtain the current browser's address where the control is located, and its return type is a string data type. 

Selenese is a Selenium command set for executing tests. 

Selenese is classified into three types: 

• Actions: They are used to interact with and operate on the target items. 
• Accessors: used to store values in variables. 
• Assertions: serve as a stopgap measure. 

To add a breakpoint:

• To begin, right-click on the command in Selenium IDE and select 'Toggle Breakpoint.'
• Then, on the keyboard, hit 'B' to pick the command.
• The same procedure should be used to remove a breakpoint.
