Hexaware Recruitment Process

As said earlier, there are three rounds in the Hexaware interview process.

  • Written Test

In this round, you must sit for a written test. You will be asked questions from quantitative aptitude, logical reasoning, verbal ability, and technical questions. This test lasts for 2.30 hours with over 170-180 questions. The technical questions cover computer topics for computer science candidates and other subjects for non-computer candidates.

  • Technical Interview

Those who clear the written test can attend the technical interview. In this round, you will be asked questions by a panel of interviewers on OOPs, Operating Systems, DBMS, computer networks, and more. 

Additionally, you will be asked questions from programming languages such as C++, Python, Java, etc. You will be shot with questions from your previous projects, interns, experience, etc. Above all, you need to write codes for one or two problems in the programming languages mentioned earlier languages.

It is vital to note that if you clear this round, you have almost done it. You will be hired positively. However, performing well in the HR interview is crucial to get the offer letter.

  • HR Interview

It is one of the critical rounds in which you will be tested for your abilities in analytical thinking, collaboration, problem-solving, leadership skills, and many more. You will be asked questions about the vision, values as well as leadership principles. 

In this round, interviewers will be interested in knowing your family background, the degree of your interest in Hexaware, the level of information you have about Hexaware, your ability to stretch to balance workloads, your interest in learning new things in technology, your mental stamina and emotional intelligence and many more. 

In addition, interviewers will ask questions regarding your goals, milestones achieved, challenges, etc. Once you clear all these three rounds successfully, you will undoubtedly get your offer letter.

Hexaware Interview Questions For Freshers

1. What is an Abstract Class?

When a class is declared with the abstract keyword, it is known as the abstract class. We use an abstract class to achieve abstraction in Java. An abstract class will have abstract as well as non-abstract methods. Also, it can have constructors as well as static methods.

In a way, the Abstract class is restricted. We cannot instantiate an abstract class. This is why we cannot use an abstract class to create objects. If you want to access an abstract class, it must be inherited from another class. It is essential to note that We use abstract classes for security reasons by hiding the unwanted details of objects from users.

2. What do you mean by the Volatile Variable?

The volatile variable is a variable that can be changed by operating systems or other software. It is widely used in multi-threaded applications. This is the variable used to end a loop or a thread. We can read/write volatile variables from/to main memory. But volatile variables are not usually cached in temporary memory devices. We can use the volatile variable in programming languages such as C, C++, and Java,

3. What is the use of Pointers?

Pointers help to perform data manipulation and storage efficiently. In its basic form, a pointer is nothing but a variable that stores the memory address of another variable. The variable can be of any data type, such as integer, array, character, or other. And the size of the pointer can be 16 or 32, or 64-bit. We also use pointers to implement data structures such as lists, trees, and graphs.

4. State about RR Algorithm

RR algorithm stands for Round Robin algorithm that follows the context switching method. It is one of the preemptive and First Come-First Serve CPU scheduling algorithms used for multitasking. Based on this algorithm, each process in the ready state is allotted CPU only for a fixed time. Likewise, all the processes get the fixed CPU time rotationally. The main thing about this algorithm is that every process gets equal priority and time for execution.

5. What are Turnaround Time and Throughput?

Throughput indicates the number of processes executed in a unit of time. Some processes may take a very short time. For example, ten processes can be executed in one second. Also, some processes may take a long time. For instance, it will take one hour to complete a single process.

Another one, Turnaround time, denotes the time required to execute a particular process. Note that this time is calculated from the submission of the process to its completion.

6. What do you mean by Waiting Time and Response Time in CPU operation?

Waiting time is nothing but how long a process stays in the ready queue to get a CPU. In other words, waiting time is the difference between the turnaround and burst times. Another one, Response time, is the time taken by a CPU to respond to a process for the first time. 

7. What do you understand by Spiral Model in SDLC?

The spiral model essentially combines the iterative development process with the waterfall model. With this model, we can avoid risks that may arise in different stages of software development. This is because this model evaluates risks at every stage of development. We can use the spiral model to generate better outcomes for large and complex software development projects.

8. What do you mean by Zombie State?

The zombie state is terminated but not an exit state. It mainly occurs in parent-child functions. Once a child function completes execution, it sends the completion status to its parent function. However, the child function cannot exit. The child function can exit only when the parent function receives and acknowledges the completion status. Until that, the child function will be in the zombie state.

9. Define Virtual Memory

Know that virtual memory is one of the best techniques used to resolve memory shortage problems. Virtual memory is nothing but an efficient memory management technique in which secondary memory acts as a part of the main memory. This technique temporarily moves data from the RAM to the main memory. We use virtual memory when there is a requirement to multitask and run complex programs. As a result, it boosts system performance to greater levels.

10. What is DBMS?

DBMS stands for DataBase Management System. In its basic form, it is a data-keeping system used in an organized way. We can manipulate data in a database through several operations. Based on the data structure, we can classify DBMS into many types, such as relational, inverted list, hierarchic, and network. A relational database has several components, such as indexes, tables, and keys.

11. What do you understand by Database Schema

A database schema is nothing but a design with which we can properly organize data in relational databases. We might also say that the database schema is a database’s blueprint. With database schema, we can clearly understand the logical relationships between fields and tables in databases. Mainly, database schema assists developers in accessing and managing data in databases efficiently.

Know that we can design database schema through data modeling. There are three types of database schema, as listed below:

  • Logical database schema
  • Conceptual schema
  • Physical database schema

12. What do you understand by Recursive Function?

A recursive function is nothing but a routine that calls itself either directly or indirectly. We use iterative methods to write the recursive functions. We can write efficient codes using recursive functions. Mainly, we can easily compile a set of numbers or strings using a single iterated process. Also, we use recursive functions to solve puzzles quickly. Know that there are three recursive functions: tail recursion, head recursion, and body recursion.

13. What do you mean by inheritance?

Inheritance is one of the crucial OOPs concepts. According to this concept, a child object gets all the properties of a parent object, absolutely. The primary use of this concept is that we can build new classes from the existing classes. Besides, we use inheritance for code reusability and method overriding.

14. State the key differences between C and C++.



It is essentially a procedural or structural-oriented language. It executes codes line by line.

It is essentially an object-oriented language. It supports OOPs concepts such as polymorphism, encapsulation, inheritance,  and abstraction.

It doesn’t support functions as well as operator overloading.

It supports functions as well as operator overloading.

It doesn't support built-in data types.

It supports built-in data types.

It doesn't have access to modifiers.

It has access modifiers.

15. Differentiate Stack with Queue in Data Structures?

Though stack and queue are linear and non-primitive data structures, they have many differences, as follows:



It uses the Last In and First Out (LIFO) approach to store data elements

It uses the First In and First Out (FIFO) approach.

We use POP and PUSH operations to insert and delete data elements in the stack, respectively.

We use Enqueue and Dequeue operations to insert and delete data elements in the queue.

Both Insertion and deletion take place at one point

Both Insertion and deletion take place at two points – Rear and Front

Stack is a vertical collection of data elements

A queue is the horizontal collection of data elements

There is no other type of stack

There are three types of queues: double-ended, circular, and priority.

With a stack, you can quickly solve recursion-based problems

With a queue, you can quickly solve sequential processing problems.

16. Create a C program to determine two numbers' Least Common Multiple (LCM).

First, we assume that n1 and n2 are two integer numbers. Now, we can find the LCM of the two numbers using the below code.

17. Under what circumstances can we use the data types such as VARCHAR, CHAR, and VARCHAR (MAX)?

When data has a variable length, we can use data types such as VARCHAR as well as VARCHAR (MAX). Particularly when the data size goes beyond 8k bytes, we can use a datatype like VARCHAR (MAX). Know that the VARCHAR data type employs dynamic memory location. It is essential to note that the data could be a letter, number, or character.

When data has a defined length, CHAR data type can be used. Unlike VARCHAR, the CHAR data type uses a static memory location.

18. Describe the steps involved in working Round Robin (RR) Algorithm?

Round robin algorithm works based on the first come- first serve method. Below are the steps involved in the execution of the RR algorithm.

  • The ready queue is loaded with all the processes for execution
  • The Burst Time (BT) of each process and the Time Quantum (TQ) of the CPU are compared with each other
  • If the BT is less than TQ, then the process is executed by the CPU for its entire Burst time
  • If the BT exceeds TQ, the process is executed up to the time quantum.
  • Then, the process is checked to determine whether the execution is complete.
  • If the execution is completed, then the process will be terminated. Otherwise, the process will be sent back to the ready queue for the next cycle of execution.

19. How would you implement Bubble Sort Algorithm?

The bubble sort algorithm uses the compare and swap method to sort array elements. With this algorithm, we can sort in ascending or descending order.

Consider that we will perform sorting for an array in ascending order.

  • The bubble sort algorithm compares the first two elements of the array.
  • They are swapped if the second element has a smaller value than the first one. In reverse, if the second element has a greater value than the first one, there is no element swapping.
  • This process of comparing and swapping elements continues until the last two elements of the array are compared.
  • All the above steps represent a single iteration of comparing and swapping elements of the array
  • Likewise, this algorithm performs many iterations until all the elements in the array are sorted in ascending order.

20. Compare NumPy Array and List in Python.

Numpy Array

Python List

It supports similar data types

It supports different data types

It is homogenous

It is homogeneous as well as heterogeneous

It demands low memory

It demands large memory

It is faster

It is slower compared to the Numpy array

21. Why Doesn’t Java Support Multiple Inheritance?

Java doesn’t support multiple inheritances since it creates the diamond problem. Because of this problem, the compiler gets confused with executing superclasses.

22. When is a trigger invoked in DBMS?

A trigger is invoked automatically when there is a special event in the database. For example, a trigger is invoked when a row is inserted in a table in the database. Also, a trigger is invoked when a column is updated in the database.

23. Describe the Self-join

Self-join is essentially a regular or inner join. This join represents the unary relationship. In this type, the rows of a table are joined by themselves. In other words, it is the join performed between two copies of the same table.

24. How can you use the super ( ) and this ( ) method with a constructor?

We can use super ( ) and this ( ) method to call constructors. This ( ) calls the constructor of the current class, whereas super ( ) calls the base class's constructor. We use this method only inside the constructor.

25. Can we declare a Constructor as Private?

Yes. We can declare a constructor as private. We can do this when we cannot create an object of a class. More to the point, we can use private constructors only in the singleton design pattern.
