C is a procedural programming language, while C++ is an object-oriented programming language that extends C with features like classes, inheritance, and polymorphism.
Example:
- C: Emphasizes functions and structured programming.
- C++: Supports both object-oriented and procedural programming, making it more flexible for modern application development.
5. What are the OOP principles, and why are they important?
Object-Oriented Programming (OOP) is based on four core principles:
- Encapsulation: Hiding data to protect it from outside interference.
- Abstraction: Simplifying complex systems by modeling classes appropriate to the problem.
- Inheritance: Enabling new classes to inherit properties of existing ones.
- Polymorphism: Allowing methods to do different things based on the context.
Interview Tip: Relate how these principles improve code reusability, scalability, and maintainability.
6. How do you handle errors in programming?
Error handling ensures programs run smoothly, even when unexpected situations arise. Common techniques include:
- Exception Handling: Used in languages like Java and Python.
- Try-Catch Blocks: Help catch and manage errors without terminating the program.
Sample Answer: “I handle errors by writing clean, well-documented code and using structured error-handling mechanisms, such as try-catch blocks, to ensure errors are caught and managed appropriately.”
7. What is SDLC, and what are its stages?
The Software Development Life Cycle (SDLC) is a process for planning, creating, testing, and deploying software. Key stages include:
- Requirement Analysis
- Design
- Implementation
- Testing
- Deployment
- Maintenance
Pro Tip: Mention Agile and Waterfall as common SDLC models and describe how Agile is widely used in today’s industry.
8. Can you explain the concept of Agile methodology?
Agile methodology is a project management approach that emphasizes iterative development, collaboration, and flexibility. It’s popular in software development for delivering high-quality products faster.
Interview Tip: Discuss how Agile enables continuous improvement through sprints, daily stand-ups, and regular feedback loops.
9. What are some data structures, and when would you use them?
Data structures are ways to store and organize data efficiently. Common types include:
- Array: Fixed-size collection, useful for indexed data.
- Linked List: Ideal for dynamic memory usage.
- Stack/Queue: Used in scenarios requiring LIFO/FIFO operations.
- Tree/Graph: Suitable for hierarchical or interconnected data.
Example: “I’d use an array for storing a fixed number of elements and a linked list for flexible, dynamic data storage.”
10. What is normalization in databases, and why is it important?
Normalization organizes data in a database to reduce redundancy. It divides large tables into smaller ones and defines relationships between them.
Benefits:
- Minimizes data redundancy.
- Improves data integrity.
- Enhances query performance.
11. Explain joins in SQL.
Joins combine rows from two or more tables based on related columns. Types of joins include:
- Inner Join: Returns records with matching values in both tables.
- Left Join: Returns all records from the left table and matched records from the right.
- Right Join: Returns all records from the right table and matched records from the left.
- Full Join: Returns all records when there is a match in either table.
12. What is cloud computing, and what are its types?
Cloud computing provides scalable computing resources over the internet. Its main types are:
- IaaS (Infrastructure as a Service): Offers virtualized hardware.
- PaaS (Platform as a Service): Provides a platform for developers to build applications.
- SaaS (Software as a Service): Delivers software applications over the internet.
13. Describe your experience with data structures and algorithms.
Data structures and algorithms are fundamental for efficient software development. You can talk about your familiarity with common data structures (arrays, linked lists, trees) and algorithms (sorting, searching).
Sample Answer: “I regularly use data structures like arrays and trees to organize data and algorithms like quicksort and binary search to enhance efficiency in my programs.”
14. What do you know about TCS’s work culture?
TCS’s work culture emphasizes respect, teamwork, integrity, and continual learning. TCS promotes diversity and encourages employees to upskill and innovate in a supportive environment.
