Hexaware Interview Questions for Freshers

As a fresher, the prospect of attending the first interview at Hexaware Technologies seems intimidating due to the lack of understanding of the specifics. In reality, there is a positive side to this experience. Hexaware identifies and follows a systematic approach for dealing with candidates, so with the right efforts put in, applicants will clear all rounds with ease.

1. Tell me about yourself.

My name is [Insert Name], and I am a B.Tech student in computer science, graduating in the year 2025. In the last year of my academic pursuit, I created and designed a portal for employee attendance management using the programming language Java with the MySQL database. This taught me a lot about backend programming and database optimisation. I have also been awarded a certificate for completing a short-term course in Python programming, as well as solving 150 programming questions from the coding website HackerRank, which improved my skill set and ability to tackle complex problems.

2. What is Object-Oriented Programming (OOP)? Explain with an example.

OOP structures programs into reusable, modular classes and objects. It’s similar to creating blueprints before constructing a home.

Four OOP pillars with a real-life analogy:

Example Code:

class Vehicle {

    void start() { System.out.println("Vehicle starts"); }

}


class Car extends Vehicle {

    void start() { System.out.println("Car starts smoothly"); }

}


public class Main {

    public static void main(String[] args) {

        Vehicle v = new Car();

        v.start();  // Output: Car starts smoothly

    }

}

When learning OOP, the modular nature and tidy class structures appealed to me. By classifying workers and departments, the attendance portal project illustrated the advantages of quick debugging and administration.

3. Difference between Stack and Queue.

• A stack works on LIFO — Last In, First Out.
• A queue works on FIFO — First In, First Out.

For me, stacks make sense whenever I need to reverse something, like undoing an action in an editor. Queues, on the other hand, are perfect when tasks need to be processed in the order they arrive, like managing customer requests.

4. Explain Round Robin Scheduling.

Each process gets an equal time slice (quantum) in the Round Robin scheduling. When time is up, the process goes to the end of the line and waits for its turn.

It’s like playing online multiplayer games. You have a set time, and when it’s game over, you go to the end of the line. 

This way, everyone gets a turn, and it’s fair to all.

5. Difference between C and C++

I started with C, which helped me a lot. After that, I switched to C++ since I wanted to modularise programs with classes and use inheritance.

As an instance in my mini-project ‘banking system simulation’, I have used C++.

6. What is a Trigger in SQL?

A trigger is a unique type of stored SQL program that gets executed automatically upon the occurrence of a definable event (INSERT, UPDATE, DELETE) on a table.

Example:

CREATE TRIGGER update_timestamp

BEFORE UPDATE ON employees

FOR EACH ROW

SET NEW.updated_at = NOW();

I find such a trigger useful and have used it in my project to automatically update what the user records’ timestamps are and in what cases they were modified. That takes care of a step and reduces the possibility of errors.

7. Write a Python program for the Fibonacci series.

def fibonacci(n):

    a, b = 0, 1

    print(a, b, end=" ")

    for _ in range(2, n):

        a, b = b, a + b

        print(b, end=" ")


fibonacci(10)  # Output: 0 1 1 2 3 5 8 13 21 34

I find Python to have a clean syntax; hence, generating a Fibonacci series is easy. I implemented an iterative approach rather than a recursive one to make it efficient.

8. What is inheritance in OOP? Provide an example.

Inheritance is like a family bloodline for the traits a person takes on. In OOP, a subclass “inherits” attributes and behaviours of the parent class. For example, in Java:

class Animal {

    void eat() { System.out.println("Animal eats"); }

}


class Dog extends Animal {

    void bark() { System.out.println("Dog barks"); }

}


public class Main {

    public static void main(String[] args) {

        Dog d = new Dog();

        d.eat();  // Inherited method

        d.bark(); // Own method

    }

}

This helps in keeping a clear and simple structure while eliminating duplicate code.

9. Explain the difference between a primary key and a foreign key.

A column, or group of columns, in a table that uniquely identifies every row in that table is called a primary key. The primary key value cannot be the same in two rows, nor can it contain NULL values.

A column or group of columns in one table (the “child” table) that points to the primary key of another table (the “parent” table) is known as a foreign key. This establishes a connection between the two tables.

Here, student_id in “Enrolments” is tied to the Students table, preserving the integrity of the data.

10. What is normalization in databases?

Normalization is like putting organized piles of clothes in a wardrobe, each into a labelled drawer, and not one big heap. It reduces redundant, inconsistent data. Normalisation is typically done using the First (1NF), Second (2NF), and Third Normal Forms (3NF) to remove the partial and transitive dependencies.

11. What does the static keyword do in Java?

static variables or methods are the property of the class and not of the instances. This means:

class Counter {

    static int count = 0;

    Counter() { count++; }

}


Counter c1 = new Counter();

Counter c2 = new Counter();

System.out.println(Counter.count); // Outputs: 2

Class names can access static members without creating an instance of the class.

12. How do you optimize SQL queries?

I usually:

• Look forward to seeing which part of the action takes surprisingly long to execute.
• Use indexes strategically on columns used in WHERE or JOIN.
• Avoid SELECT *; only fetch needed columns.
• Write efficient joins and conditions to filter early.

13. Difference between GET and POST in HTTP.

GET: Mainly used to fetch information from a designated server resource. It should not be used to change the state of the server.

POST: Mainly used to send information to the server in order to create or modify a resource. Its purpose is to alter the server.

14. How do you debug code?

I begin reproducing the issue, then utilise available tools or add logging to systematically walk through the code. I examine variable values, analyse the failure, or diagnose the problem until I identify its root cause. I then validate the correction across multiple conditions.

Hexaware Interview Questions for Intermediate/Experienced Professionals

15. Explain the MVC architecture.

MVC stands for Model-View-Controller:

• Model: Controls data and business logic.
• View: Interacts with the Client/Handles the UI
• Controller: Syncs the two, manages the Model with respect to user actions, and the View to be shown.

So if a user were to press a button, the Controller would manage and update the data to show the user’s View and change the Model accordingly.

16. What is a Recursive Function?

A recursive function calls itself to solve a problem. It’s like standing between parallel mirrors; you keep seeing yourself forever, but there’s always an endpoint (base case) that breaks the cycle.

Example – Factorial in Python:

def factorial(n):

    if n == 1:

        return 1  # base case

    return n * factorial(n - 1)  # recursive call


print(factorial(5))  # Output: 120

17. Explain Pointers (C/C++)

A pointer is a variable that doesn’t hold a value directly. Instead, it holds the memory address of another variable.

Visual:

[x = 10] ← stored at address 0x0010  

 ptr = 0x0010  ↘ points to x

Code:

int x = 10;

int *ptr = &x;     // ptr holds the address of x

int value = *ptr;  // indirect access: value = 10

18. Near, Far & Huge Pointers (Old Memory Models)

• Near pointer: 16-bit; can only refer to memory within the same segment.
• Far pointer: 32-bit; can refer to other segments of memory.
• Huge pointer: 32-bit; access pointer arithmetic and cross-segment boundaries.

Think of it as city maps:

• Near: street-level.
• Far: Neighbourhood.
• Huge: an entire city with navigation.

19. Instance Variables in Java

Instance variables are those that are declared in a class but outside any of its methods. Every object holds personal notes that are tied to every instance and thus are unique.

class Person {

    String name;  // instance variable

    int age;

}

Now, consider creating two Person objects. You will find that they each maintain their own, separate, private copies of name and age.

20. Why No Multiple Inheritance in Java?

It is correct that Java does not allow multiple inheritance because that would lead to confusion, such as trying to determine which parent to inherit a method from if both define it differently. Java implements multiple inheritance by using interfaces, which takes away almost all the confusion.

21. Package vs Interface in Java

A package is a container that prevents naming conflicts by providing limited access. It also helps to organise related classes, interfaces, annotations, and enumerations as a whole.

Each interface is a class blueprint and passes a mandate to the class that implements it, which the class line must adhere to. Also, interfaces hold abstract class methods that are default, static, and constant.

22. Abstract Class in Java

An abstract class is an incomplete blueprint. One cannot create objects from an abstract class. A subclass effectively implements the features, which is ideal when looking for a base template with similar behaviour.

abstract class Shape {

    abstract void draw();  // must be implemented by subclasses

}

23. Union vs Anonymous Union

• Union: In C and C++, a union is a unique data type that enables the storage of various data types in the same memory address. The union’s largest member determines its size, and only one member may hold a value at a time.
• Anonymous Union: An anonymous union is one that lacks a name or tag and is usually affiliated with another organisation or union.

union MyUnion {

    int i;

    float f;

};

24. Private Constructor

In object-oriented programming languages such as Java or C#, a private constructor is a unique kind of constructor that possesses the private access modifier. This modifier limits the constructor’s accessibility, preventing it from being called from outside the class or from derived classes.

class Singleton {

    private static Singleton instance = new Singleton();

    private Singleton() {}

    public static Singleton getInstance() { return instance; }

}

25. this() vs super() in Constructors

• this(): Calls another constructor within the same class.
• super(): Calls the parent class’s constructor.

class Parent {

    Parent(int x) {}

}

class Child extends Parent {

    Child() {

        super(10);

        this(); // error if no matching constructor

    }

}

26. What is DBMS?

A database management system (DBMS) is a software program that effectively organises, stores, and retrieves data in a structured manner.

• It enables users to efficiently create, update, and query databases.
• Guarantees the security, consistency, and integrity of data across numerous users and applications.
• Uses centralised control to lessen data inconsistency and redundancy.
• Allows for automatic backups, transaction management, and concurrent data access.

27. What are Stacks and Queues?

A stack is a list of elements where only one end, referred to as the top of the stack, allows the addition or deletion of elements. LIFO (last in, first out) lists are another name for stacks. 

Since the items can only be added or removed from the top, the last item added to a stack is also the first item removed.

Another unique type of list is a queue, in which items are added at the back end and removed at the front end. A “FIFO”, or “first-in-first-out”, list is another term for a queue.

The insertions go at the end of the list instead of the beginning, but otherwise, the operations for a queue are the same as those for a stack.

28. LCM of Two Numbers — C Code Example

#include 

int main() {

    int num1 = 36, num2 = 60, lcm;

    int max = num1 > num2 ? num1 : num2;

    for (int i = max; i <= num1 * num2; i++) {

        if (i % num1 == 0 && i % num2 == 0) {

            lcm = i;

            break;

        }

    }

    printf("The LCM: %d", lcm);

    return 0;

}

29. What is a Deadlock?

A deadlock occurs when each of two programs waits on the other to release a resource, and as a result, neither can continue. For example, two cars on a single-lane bridge in opposing directions.

I find it useful while learning about locking resources to see if my codes deal safely with concurrency.

30. Check Armstrong Numbers in a Range (C++)

#include <bits/stdc++.h>

using namespace std;

int order(int x) {

    int len = 0;

    while (x) {

        len++;

        x /= 10;

    }

    return len;

}


void findArmstrong(int low, int high) {

    for (int num = low; num <= high; num++) {

        int sum = 0, temp = num, digit, len = order(num);

        while (temp) {

            digit = temp % 10;

            sum += pow(digit, len);

            temp /= 10;

        }

        if (sum == num) cout << num << " ";

    }

}


int main() {

    findArmstrong(100, 999);

    return 0;

}

This checks all 3-digit Armstrong numbers in the range.

31. Recursive Fibonacci Series (Python)

def fibonacci(n):

    a, b = 0, 1

    print(a, end=' ')

    print(b, end=' ')

    for _ in range(2, n):

        a, b = b, a + b

        print(b, end=' ')

fibonacci(10)  # Prints first 10 Fibonacci numbers

Loops are easy to use and effective for creating Fibonacci sequences.

32. Node, Stream, and E-R Model Basics

1. Node Basics

The definition of ‘node’ is likely to change depending on the context. In the case of data structures, a node can be an element of a linked list, a tree, or a graph. Each node contains bits of information alongside a certain number of associated nodes.

Example (Linked List Node):

class Node {

    int data;

    Node next;

}

Each node in this case holds a pointer to the node after it, as well as some data.

In the case of networking, a node can be referred to as a single device on a network, whether it be a laptop, server, or printer.

2. Stream Basics

A stream can be thought of as a pipe, where the flow of water is replaced with the flow of information.

In programming, streams are a technique to read or write data continuously.

There are two types:

• In the Input Stream, data flows to a programme as its destination. 
• In the Output Stream, a program is the source of data flowing out.

Example in Java:

FileInputStream fis = new FileInputStream("data.txt");

int ch;

while((ch = fis.read()) != -1) {

    System.out.print((char) ch);

}

fis.close();

By using an Input Stream, I was able to read data from a file.

3. E-R (Entity-Relationship) Model Basics

An E-R model depicts the process of designing a database in the form of a chart. It identifies the various components that make up one or more entities of the real world, as well as the attributes that distinguish them and the connections that bind them.

An entity can be described as the constituent elements of a database, like a student or a course.

An entity’s attributes are the set of properties associated with it, such as a student having a name and roll number or a course having a course ID and a title.

A relationship can be illustrated by the action of a student enrolling in a course, where multiple entities are involved, thus defining how the entities are linked.

In my opinion, an E-R model assists with perceiving what the data bank will look like even before the tables have been constructed.

Hexaware Technical Interview Questions 

Each technical question in this section is drawn from several reputable sources and customised for more intermediate/experienced candidates. Each answer is designed to be comprehensive and succinct, complete with practical examples or illustrations to ensure your answers are memorable.

33. Explain the differences between procedural and object-oriented programming.

Procedural programming is like following a recipe step by step: user-defined functions are constructed with logic, and data flows freely among them. The programming paradigm known as object-oriented programming (OOP) arranges software according to “objects”, which are independent units that combine data (attributes) and the functions (methods) that manipulate that data. This method facilitates greater modularity, simpler upkeep, and better-defined logic. For instance, in a vehicle management system, I would create a Vehicle class and then derive a Car or Bike from it. Each would manage its own specifics while sharing core logic.

34. What are the main advantages and limitations of OOP?

Object-oriented programming (OOP) is a style of coding in which we group all the items into objects (real-life objects) rather than functions and procedures.

The key benefits include code reusability, better organisation, and simpler maintenance. However, OOP also contains some drawbacks, such as increased memory and a slightly more complicated design than procedural programming.

35. What are user-defined functions in SQL, and what is an inline table-valued function?

User-defined functions (UDFs) are the functions that permit you to encapsulate logic in SQL for use in multiple places. They include scalars (return a single value), multi-statement table-valued functions (TSVs that include some control flow logic), and inline table-valued functions, which are my favourite. An inline TVF is a function that, when invoked, returns a table that behaves like a bona fide table. This is useful for clarity and enhanced performance in cases of JOINs and other queries. The function is invoked and is inserted effortlessly in the FROM clause.

36. What is network topology, and why is it important?

Network topology describes the shapes of network nodes (devices) as stars, buses, rings, or meshes. It has a direct effect on the reliability of a system, latency, and ease of growth. As an example, a star topology only brings failures to a single node, whereas a mesh offers redundancy, which is ideal in the case of a mission-critical system. The choice of the appropriate topology is concerned with cost, resilience, and performance.

37. What is a database schema?

A database schema is simply the blueprint, which involves descriptions of tables, columns, data types, relationships, and constraints. It does not save data; it determines the design. The frontal cleanliness of a schema is analogous to the planning of a building with supporting beams. Once the frame is sturdy, everything constructed upon it will be firm and easier to control.

38. Why is SQL query performance tuning important for enterprise systems?

Regular optimisation of queries makes them readable and faster overall. This includes using indexes on columns that are filtered or are the subject of joins, avoiding the use of SELECT * in order to limit the data that is fetched, and using smart window functions, subqueries, and execution plans. The elimination of bottlenecks also contributes to response time. Efficient queries mean faster responses, lower costs, and happy users, especially on a large scale.

39. What kind of coding challenges can an experienced candidate expect at Hexaware?

Hexaware tech rounds include real-world coding challenges like pattern recognition, string challenges, and logic puzzles in Java, C++, and Python. For instance, they have legacy patterns or system storylines like ‘Guess the Word’ in order to understand a person’s logical capabilities. I practise with diverse datasets and edge cases.

40. What’s your experience working with version control systems like Git?

In my recent projects, Git has been the application of my choice. I have always appreciated feature branches for new tasks, PRs for peer reviews, semantic commit messages for the clarity of history, and do, indeed, appreciate rebasing. For complex merges, I use conflict resolution and thorough testing. There is more to version control than just the history; it is the promise of collaboration.

41. CHAR vs VARCHAR—when to use which?

Use CHAR when the length of the data is fixed, such as country codes, as it uses the same amount of storage space for all data. Use VARCHAR for variable-length data such as names, as it is more space efficient, particularly with data of varying lengths.

42. List vs NumPy Array—what’s the difference? 

Lists are easy to use and more flexible, but NumPy arrays are much more efficient and built for large, complex computation, which is when speed is essential.

43. Implement reversing a number or string in Python. 

To reverse a number:

value = 502

reverse = 0

while value:

    reverse = reverse * 10 + (value % 10)

    value //= 10

print(reverse)  # 205

To reverse a string:

s = "Podium"

print(s[::-1])  # 'muidoP'

Hexaware HR Interview Questions

The most common Hexaware HR interview questions and their suggested responses are provided in this section to help candidates prepare, just like in many other trustworthy sources.

44. How do you keep up with new technologies?

In my case, I try to keep myself updated with the relevant information, and this is why I subscribe to tech newsletters. Every few months, I also try to complete certificated mini-courses, and I try to learn new concepts by solving problems on websites like HackerRank. This also shows my proactive and continuous positive improvement perspective.

45. How would you benefit the company if hired?

In the case of Hexaware, I will bring a unique combination of skills, which includes the relevant technical skills with emotional and social adaptability, along with the ability to work as part of a team. I also make sure the work I deliver is on time to the required deadline, and so I am able to learn the relevant tech stacks quite fast.

46. What do you know about Hexaware?

I am aware that Hexaware, a multinational IT company, began as a small business in 1990 under the direction of Atul K. Nishar. Today, the firm has a good reputation for offering solutions in digital assurance, enterprise automation, and innovative systems. In addition to this, the firm is based in a number of major cities in India, such as Mumbai, Chennai, and Bengaluru, and is well known for its commitment towards employee development.

47. Give an example of your creativity.

In my previous internship, I generated reports including a plethora of data and slides, besides automating the entire process using a Python script. I completed this process in under 2 minutes and thirty seconds as opposed to a manual process, which took hours. I was able to lower the time taken to create reports whilst also lessening the number of errors present. You don’t always have to think outside the box in a creative manner. Sometimes, improvements that have little worth can lead to wonderful relationships.

48. Tell me about the most challenging decision you’ve ever made and how you made it.

Once, I had to choose between two conflicting project features. I created a pros/cons list, discussed it with stakeholders, and aligned on priorities. I chose flexibility over complexity, and it ended up improving user acceptance and team productivity. Making decisions based on data and collaboration helps me navigate tough choices.

49. How would you handle not being promoted after five years?

I strongly believe in contribution growth and learning through the process, not simply for the sake of achievements. After five years and no promotion, I expect my manager to set performance milestones and future expectations that revolve around upskilling and building upon the stellar work that I have been delivering. That mindset shows maturity, commitment, and a long-term perspective.

50. Where do you see yourself in five years? 

Looking ahead, in five years, I envision myself in the role of a technical lead or project manager. I want to be a person not just devoted to the crafting of hands-on solutions but also able to lead and support others on their journey. It is my ambition to become a mentor and guide my colleagues to success, while improving my own skillset in architecture and leadership.

51. Are you open to night shifts or relocations? 

I understand Hexaware operates around the world, and I am willing to embrace new challenges in alignment with business objectives. I am flexible, and I am driven to engage in learning opportunities.

52. What are your expectations from the company? 

I do envision a workplace culture where there is a proven record of collaboration and where I am also able to pursue technical and leadership opportunities. I value openness in communication, proactive support in mentorship, and the chance to work towards achieving important and meaningful goals.
