Technical Interview Questions

13. Explain Object-Oriented Programming Concepts

OOP concepts are among the most commonly asked technical questions for Cognizant freshers, especially for candidates from computer science backgrounds.

Interviewers ask this question to check your understanding of programming fundamentals.

How to answer:

Explain the four main pillars of OOP:

• Encapsulation
• Inheritance
• Polymorphism
• Abstraction

Sample Answer:

“Object-Oriented Programming is a programming approach based on objects and classes.

The four main concepts of OOP are:

Encapsulation: It combines data and methods into a single unit and provides data security.

Inheritance: It allows one class to acquire properties and behaviours of another class.

Polymorphism: It allows methods to perform different functions based on the situation.

Abstraction: It hides unnecessary implementation details and shows only essential information to users.”

14. Difference Between Class and Object

This question checks your basic understanding of object-oriented programming.

How to answer:

Explain the difference with a simple example.

Sample Answer:

“A class is a blueprint or template used to create objects. It defines the properties and behaviours that an object will have.

An object is an actual instance of a class that represents a real-world entity.

For example, a class can be considered a blueprint of a car, while a specific car created using that blueprint is an object.”

15. Difference Between Method Overloading and Method Overriding

This is a common Java and OOP interview question.

How to answer:

Explain the difference based on:

• Definition
• When it happens
• Purpose

Sample Answer:

“Method overloading means having multiple methods with the same name but different parameters within the same class. It is an example of compile-time polymorphism.

Method overriding happens when a child class provides a different implementation of a method already defined in the parent class. It represents runtime polymorphism.”

16. What Are the Four Pillars of OOP?

This is a frequently asked technical question for software development roles. Cognizant interviewers ask this to check whether you have a strong understanding of object-oriented programming fundamentals.

How to answer:

Explain all four concepts briefly with their practical meaning:

• Encapsulation
• Inheritance
• Polymorphism
• Abstraction

Sample Answer:

“The four pillars of Object-Oriented Programming are:

Encapsulation: It combines data and methods into a single unit and restricts direct access to data for better security.

Inheritance: It allows one class to reuse the properties and methods of another class, which improves code reusability.

Polymorphism: It allows the same method or function to behave differently in different situations.

Abstraction: It hides complex implementation details and only shows the required information to the user.

These concepts help developers create structured, reusable, and maintainable programs.”

17. Explain DBMS and Its Importance

Database Management System is an important topic for Cognizant technical interviews, especially for candidates applying for software and data-related roles.

How to answer:

Explain:

• What DBMS is
• Why it is used
• Real-world applications

Sample Answer:

“A Database Management System, or DBMS, is software used to store, manage, organise, and retrieve data efficiently.

It allows users and applications to interact with databases while maintaining data security, consistency, and accuracy.

For example, banking systems use DBMS to store customer information, transaction details, and account records securely.”

18. Difference Between Primary Key and Foreign Key

This question tests your understanding of database relationships and data integrity.

How to answer:

Explain the purpose and difference clearly.

Sample Answer:

“A primary key is a column or combination of columns that uniquely identifies each record in a table. It cannot contain duplicate or null values.

A foreign key is a column that creates a relationship between two tables by referring to the primary key of another table.

For example, a customer ID can be a primary key in a customer table and the same customer ID can act as a foreign key in an order table.”

19. Explain SQL Joins With Examples

SQL joins are commonly asked in Cognizant technical interviews because databases are an important part of software development.

How to answer:

Explain that joins are used to combine data from multiple tables.

Mention common types:

• Inner Join
• Left Join
• Right Join
• Full Join

Sample Answer:

“SQL joins are used to combine data from two or more tables based on a related column.

An Inner Join returns only the matching records from both tables.

A Left Join returns all records from the left table and matching records from the right table.

For example, if we have a customer table and an order table, joins can help us combine customer details with their order information.”

20. Difference Between DELETE, DROP, and TRUNCATE

This is a common SQL question asked to check your understanding of database operations.

How to answer:

Explain the difference based on:

• Type of operation
• Data removal
• Table structure

Sample Answer:

“DELETE, DROP, and TRUNCATE are used for removing data in SQL, but they work differently.

DELETE: Removes selected records from a table and can use conditions with WHERE.

TRUNCATE: Removes all records from a table but keeps the table structure.

DROP: Completely removes the table along with its structure and data.

For example, if we only want to remove specific customer records, we use DELETE. If we want to remove the entire table, we use DROP.”

21. What Is Normalisation in Database?

Interviewers ask this question to check your understanding of database design and avoiding data duplication.

How to answer:

Explain:

• Meaning of normalisation
• Purpose
• Benefits

Sample Answer:

“Database normalisation is a process of organising data in a database to reduce redundancy and improve data consistency.

It divides large tables into smaller related tables and establishes relationships between them.

The main benefits of normalisation are reducing duplicate data, improving data accuracy, and making database management easier.”

22. Difference Between Process and Thread

This question tests your operating system fundamentals, which are commonly asked in technical interviews.

How to answer:

Explain the difference based on:

• Definition
• Memory usage
• Execution

Sample Answer:

“A process is an independent program that has its own memory space and resources.

A thread is a smaller unit of execution within a process that shares the same memory resources.

Processes are heavier and require more resources, while threads are lightweight and allow faster execution within applications.”

23. What Is Exception Handling?

Exception handling is an important programming concept, especially in languages like Java and Python.

Interviewers ask this to understand whether you know how to handle errors in programs.

How to answer:

Explain:

• Meaning of exception handling
• Why it is used
• Common keywords

Sample Answer:

“Exception handling is a mechanism used to handle runtime errors and prevent the program from crashing unexpectedly.

It allows developers to manage errors and maintain the normal flow of execution.

In Java, exception handling is implemented using keywords like try, catch, finally, and throw.”

24. Write a Program to Check Whether a String Is Palindrome

Coding questions are often included in Cognizant technical interviews to evaluate your logical thinking and programming approach.

How to answer:

Explain your logic first before writing the code.

Logic:

• Reverse the given string
• Compare it with the original string
• If both are equal, it is a palindrome

Sample Answer (Java):

public class Palindrome {
    public static void main(String[] args) {
        String str = "madam";
        String rev = "";

        for(int i = str.length()-1; i >= 0; i--) {
            rev = rev + str.charAt(i);
        }

        if(str.equals(rev)) {
            System.out.println("Palindrome");
        } else {
            System.out.println("Not Palindrome");
        }
    }
}

25. Do You Have Any Questions for Us?

This is usually the final question in a Cognizant interview. Many candidates ignore this opportunity, but asking thoughtful questions shows your interest in the role.

How to answer:

Ask questions related to:

• Role responsibilities
• Learning opportunities
• Team structure
• Growth opportunities

Avoid asking only about salary or benefits during the first interaction.

Sample Answer:

“Yes, I would like to know more about the learning opportunities available for freshers at Cognizant and how the organisation supports employees in developing new technical skills.

I would also like to understand the type of projects that freshers usually get an opportunity to work on.”
