TCS Interview Questions

TCS is one of the largest companies in consulting, technology, and software and is a job seeker’s dream job to be employed by.

The company hires thousands of graduates from management every year. Are you wondering what makes them get into the company? It’s certainly not easy; however, it’s not impossible to break.

An essential step for interview preparation for new graduates is to consider what attire to wear on the big day. After all, the cliche “first impressions last” also rings true when it comes to job interviews.

For best results, aim to present yourself in the most presentable way possible and memorize common HR interview questions for freshers.

Ensure your formal shirt, trousers/skirt are clean and well-pressed; polished shoes with clean socks; well-groomed hair and nails are shiny too.

1. Explain the purpose of linked lists

A linked list has two components: information and the link. In single listening, the start in the list will be identified by a specific pointer whose name begins.

The pointer is the first element in the list, and the link component of every node is an arch that leads to the next node; however, the final node in the list is missing a pointer that indicates the previous one. Thanks to the start pointer, the linked list can be easily traversed.

2. How well do you do at managing?

This question can inform prospective employers about how you collaborated with your colleagues. This can also give them an idea of how well you managed the processes of work and your output while also interacting with your colleagues simultaneously.

TCS Work From Home 

This is a great chance to show your strengths but in a subtle manner. You run the risk of appearing boastful or confident. Try incorporating positive feedback from your career, praise from your colleagues, or LinkedIn suggestions would be helpful.

3.) How do you define inheritance?

In Object-Oriented Programming, inheritance is a method that is based on classes.

Inheritance is transferring the properties and data members of a parent class into an infant class. A style created from a different type is typically called a sub-class or child class. The type that the child class is derived from is known as Superclass or Parent Class.

4. What exactly is Polymorphism?

Polymorphism is a term used in OOPS that refers to having multiple types. But, it means that various actions can occur in different instances. The two kinds of Polymorphism are:

  1. Method of overloading
  2. Operator overloaded

5. Types of inheritance?

Kinds of inheritance:

  1. Hybrid Inheritance
  2. Single inheritance
  3. Multi-level Inheritance
  4. Multi-path Inheritance
  5. Hierarchical Inheritance
  6. Multiple Inheritance

6. Will you risk it all?

This is among the most essential aspects of any managerial job. While working, there are times when you’ll face difficulties that require one or more risks that must be taken. A successful and effective manager is always prepared and takes well-planned and well-informed risk-taking to address any issue.

Only respond with affirmative when you’re confident in being comfortable. In other words, you may affirm that before making a decision and taking a chance, you’ll take the time to conduct research and decide on the same basis.

7. What are the four basic principles of OOPS?

The four principles that underlie the Object-Oriented Programming System are listed below:

  • Abstraction is a method to hide the implementation details and only display features for the end user. For instance, sending an SMS in which you type the text and then send the message. The internal process that goes into the transmission of the message.
  • Polymorphism in Java is a term used to describe how we can act in various ways. “polymorphism” comes from two Greek words: Polyy and Morphs. In Greek, “poly” refers to many, while “morphs” refers to forms. Therefore, Polymorphism can refer to a variety of conditions.
  • Abstraction allows you to focus on what the object is doing instead of what the thing does.
  • Encapsulation: The process of encapsulation within Java is the process of wrapping data and code into one piece, for instance, a capsule made of various medicines.
  • Inheritance in Java is a method by which one object can acquire each property, property, and behavior of its parent object.

8. What’s the distinction between interfaces and classes?

The distinctions between interfaces and classes can be as follows:

  • A lesson is created by creating an object of it. However, interfaces are not instantiated since the methods of an interface have no meaning and don’t do anything, which is why there is no point in creating an interface.
  • A class is declared using the keywords for courses, while it is called an interface by using the interface keyword.
  • Class members may be granted access to protected, public, and private specifiers.
  • However, users of an interface do not be granted access specifiers, and all interface members are classified as public since the interface uses it to create from another class. There is no need for access specifiers within the interface’s members.
  • The methods within the class are designed to carry out specific operations on fields defined in the class, whereas the interfaces aren’t assertive in certain areas. The ways that the interface works are abstract.
  • A class can implement any interface but only be extended by one superclass.
  • While interfaces can be extended to an unlimited number of interfaces, they cannot perform any interface.
  • A class may contain a constructor inside the class that declares the fields within the course, while an interface does not have a constructor in place because there aren’t fields that need to be initialized.

9. What is the software development life cycle?

  • The software development life cycle involves steps in the entire software development phase.
  • It is generally carried out by the team who creates the software within the company.
  • It is a concise explanation of how to develop and maintain the software.

10. What is a Database Management System?

A DataBase Management System is a software system that is used for creating as well as managing databases. DBMS allows the user to create and manage databases. DBMS is a means of connecting the application or user and the database.

11. What are loops?

Loops can be used to repeatedly execute the same code block in a program dependent on conditional statements.

The basic layout of a circuit can be shown in the diagram above. After each successful completion in the loop, the conditional statements must be verified.

If it is accurate, it will continue to be completed. If it does not match, then the circus, thee canceled.

12. Explain Joins, Normalization, Views, and Triggers?

The JOIN keyword is utilized to create the SQL statement to retrieve data from multiple tables based on the relationship between specific columns in these tables.

The tables in a database are typically linked to each using keys.

A view is an online table. The statement contains columns and rows, just like a table. The fields displayed in a photograph are from one or more tables in the database.

I also add SQL statements, functions like WHERE, and notifications that JOIN one another to a vien, then display the data as though the data came from a single table.

13. Do you believe in delegating?

A successful manager always delegates. Delegation is a prevalent task for managers to accomplish, ensuring a consistent output. It is essential to describe how you delegated tasks in your previous job, mainly depending on the employee’s skills and knowledge.

Delegation is an art; y must demonstrate to your peers how talented you are. It would be best if you were again how well-planned your delegation process was to maximize productivity.

14. What is the normalization of databases, joins, and keys?

Normalization is the process of arranging the database’s data efficiently. The two goals of the normalization process are to eliminate duplicate data (for example,

The same information in multiple tables) and to ensure that data dependencies align with the law (only keeping related data in tables). Both of these are essential since they cut down on the space a database takes up and ensure that data is effectively stored.

15. List different advantages of DBMS

Data sharing has been improved.

The benefits that come with DataBase Management System:

  • Better data integration.
  • Improved productivity of the end-user.
  • Better data access.
  • Improved decision-making.
  • The security of data has been improved.
  • Minimal data inconsistency.

16. What are the conditional statements?

The conditional statements could also be referred to as conditional expressions as well. Conditional statements are the rules executed when the condition in question is met.

It is commonly referred to as an if-then conditional statement since If the state is valid, then the condition is carried out.

17. What is the similarity and difference between C++ and C?

C++ has classes how; ever, C does not have classes.

C is not able to allow the overloading of functions. In C, for input or output, we make use of functions such as gets() and puts() and scanf(), print(), and so on.

C doesn’t allow exception handling.

A session can be described as a logical connection between the origin and the destination.

20. What is the difference between the foreign and recent keys?

Keys referral Key refers to the key used in the second table (linked through the foreign keys of the other tables Key). Foreign Key connects the secondary tables Primary Key to primate ry table Key (or Primary KeKeyor Key Reference). Key).

21. The structural difKedifferenceeen the b-tree index and bitmap?


It is comprised of leaf nodes. BraKey nodes contain prefifundamental prefixes and links to leaf nodes. The leaf nodes have the index value and are rowed.


It’s a simple string of bits for each unique value. It makes use of an array of bits to identify rows in the table in a short time. It can be used to index columns with low cardinality.

22. What is the difference between a non Clustered index and-clustered index?

Clustered Index

  • One table per table
  • It is faster to read than data un clustered data because stored physically in the order of the index.

Non-Clustered Index

  • It can be used many times per table
  • It is faster for insert and update processes than a clustered index.

23. What is an array?

“array” refers to a set of elements with similar properties. An array’s essential requirement is that the data type of the elements in the array have to be identical. An array declaration in C++ is as the following:

int a[10[10

This describes an array that’s name is an and contains ten elements that are indexed from zero to nine

24. Memory Allocation in C/C+

Calloc() function allocates memory, and the size will result from its settings (it has two options). calloc fills the memory using zeros and then returns a pointer toward the initial byte. It will return an NUa pointer if it fails to find the space needed.

The malloc() function allocates memory space; length will be determined by the value entered in the parameter. (it is a single parameter). It doesn’t start the memory area

The free () function unfreezes allocated memory(allocated by the calloc functalloc functions). In other words, it is used to free the memory allocated

TCS CodeVita 2022

New technology is also utilized to allocate memory on the heap and then initialize the memory with the constructor

to remove e a memory that was released previously allotted by the new operator

25. Define Data Abstraction. What is their significance?

Abstraction is the process that focuses attention and recognition on fundamental characteristics of a particular subject or event and then filtefiltersundesirable aspects of the object or situation.

Abstraction is the base of software development. Through this notion, we identify the system’s most critical elements. The method of identifying and creating the concepts for a particular system is known as modeling (modeling objects).

Three levels of abstraction of data are:

  1. Level of Logical information that is stored within the database. e.g., Database administrator
  2. Physical layer The data is physically stored in the database.
  3. Level of view End users always works at the view level. If there is any change made, it can be saved with an alternative name.

26. What is the difference between the virtual function and the pure function of virtualization?

Pure Virtual Function This is the function that is used in the Base class. The definition is required to be defined in the class that is derived from it. Other pure virtual functions with no definition in the base class. Is deIt signed as:

Virtual empty fun()=0;

This means that the function won’t accomplish anything; in the event, the process is pure and virtual, the derived function must

Create a pure virtual function or declare it as an entirely virtual function.

Virtual functions To attain Polymorphism, the part of the base class can be declared virtual through state virtualization making, an; anct of the base class fulfills the role of any derived class dependent on the contents of the pointer (any purchased name of c, course).

27. What are WPF and WCF?

WPF/WCF application is required to befor.NET 3.0 Framework. This application will be able to cover the following aspects:

WCF(Windows Communication Foundation)
