TCS Full Stack Developer Interview Questions 2024
The interview process at TCS for a full stack developer position is comprehensive, covering a range of topics from technical skills to problem-solving abilities and cultural fit. Here is a detailed list of potential interview questions you might encounter:
I) Technical Questions:
1. What is an Object in OOPs?
An object is an instance or subset of the class. It is attributable to a physical operation such as individual attributes, properties and behavior. It occupies space in the memory and has member functions defined in a class.
2. What is a Class in OOPs?
A class gives the object’s outline and has a fixed data type defined by the user. Member functions, variables, constants and other functionality are designated within a class. It does not use any memory during run time. A class can exist without an object, but an object cannot exist outside the class.
3. What characterizes OOPs as a whole?
Following are some of the critical characteristics of OOPs:
- OOPS allows you to specify the variables of each data item by combining the code into a single unit. Encapsulation is the process of grouping information into a single unit.
- One can standardize your objects and make your program easier to use by utilizing classes. We refer to this as an abstraction.
- More code can be reused when a class can inherit traits and behaviors from other courses.
- With the aid of polymorphism, numerous objects can be produced from a single, flexible class of code.
4.What is the function of a super keyword?
The super keyword keyword is used to forward a constructor’s call to a constructor in the superclass. It invokes the overridden method that allows access to these methods and the superclass’s hidden members.
5. What is compile time polymorphism?
When a polymorphic call is made, and the compiler knows which function is to be called; this is known as compile-time polymorphism. The features like function default arguments, overloading, and templates in C++ support compile-time polymorphism.
7.Can we implement multiple inheritances in Java?
Java does not explicitly support multiple inheritances. With the use of an interface, we may achieve multiple inheritances. Multiple interfaces can be incorporated into our program.
8.How is method overloading different from method overriding?
Method overloading occurs when two methods have the same name but differ in the number of parameters or the type of arguments they accept. Compile-time polymorphism is what it’s called because it happens during the compilation process.
Method overriding refers to the ability to construct subclass and super-class methods with the same name and signatures, with the subclass method taking precedence over the super-class method. Run-time polymorphism is a type of polymorphism that occurs during the execution of a program.
9.What is the difference between array and pointer?
An array is a collection of comparable elements with the same data type, whereas a pointer is a variable that points to some data type in memory. Arrays can only contain components of the same data type, but pointers can link to any data type variable.
10. General Programming:
- Describe the principles of Object-Oriented Programming (OOP).
- What are design patterns, and why are they important?
- How do you handle error management and debugging in your code?
- Explain the concept of asynchronous programming in JavaScript.
- What is the difference between synchronous and asynchronous execution?
- How do you manage dependencies in a project?
- What are the SOLID principles in software development?
- What is a closure in JavaScript and how is it used?
- Explain the concept of functional programming.
- What is the role of version control systems in development?
- Describe the differences between imperative and declarative programming.
- How do you optimize code for performance?
- What are the benefits of using TypeScript over JavaScript?
- Explain the concept of recursion with an example.
- What is the difference between a stack and a queue?
- How do you handle memory management in programming?
- What is the use of garbage collection in programming languages?
- Describe the concept of event-driven programming.
- How do you implement security best practices in your code?
- What are the differences between procedural and object-oriented programming?
II) Behavioral Questions:
1. Tell me about yourself.
2. What are your greatest strengths?
3. Where do you see yourself in five years?
