What is the difference between Call by Value and Call by Reference in C/C++? **Answer:** In *Call by Value*, a copy of the actual variable is passed to the function. Changes made inside the function do not affect the original value. In *Call by Reference*, the memory address of the variable is passed, allowing the function to directly modify the original variable. ### Q2. Explain Object-Oriented Programming (OOP) Pillars with real-world examples. **Answer:** OOP is built on four core principles: - **Encapsulation:** Wrapping data and methods into a single unit (e.g., a Bank Account class hiding balance variable). - **Abstraction:** Hiding internal implementation details and showing only functionality (e.g., driving a car without knowing internal engine combustion). - **Inheritance:** Reusing code from a parent class (e.g., ElectricCar inheriting from Vehicle). - **Polymorphism:** Ability of a method to take multiple forms (Method Overloading and Method Overriding). ### Q3. What is the difference between Primary Key, Unique Key, and Foreign Key in SQL? **Answer:** A *Primary Key* uniquely identifies each row in a table and cannot accept NULL values (only 1 primary key per table). A *Unique Key* ensures all values in a column are distinct, but allows one NULL value. A *Foreign Key* references the primary key of another table to establish a relationship. ### Q4. How do you find the second highest salary in an Employee table using SQL? SELECT MAX(salary) FROM Employee WHERE salary < (SELECT MAX(salary) FROM Employee); Alternative using OFFSET: `SELECT DISTINCT salary FROM Employee ORDER BY salary DESC LIMIT 1 OFFSET 1;` ### Q5. What is Method Overloading vs Method Overriding in Java? **Answer:** *Method Overloading* occurs within the same class when multiple methods share the same name but have different parameter lists (compile-time polymorphism). *Method Overriding* occurs when a subclass provides a specific implementation of a method declared in its superclass (runtime polymorphism). ## 5. Top TCS HR & Managerial Interview Questions #### 1. Are you willing to relocate or work in night shifts? **Tip:** TCS expects 100% flexibility regarding location and shifts. Always answer positively and explain your eagerness to learn across project environments. #### 2. Why do you want to join TCS over other IT companies? **Tip:** Mention TCS's global reputation, Tata work ethics, continuous learning platforms (iON, Elevate), and stability. #### 3. Walk me through your final year project. What was your personal contribution? **Tip:** Structure your answer with the STAR method (Situation, Task, Action, Result). Explicitly state the technologies used, challenges faced, and how you solved them. ### Practice TCS Voice Mock Interviews For Free Don't just memorize answers—practice speaking them out loud!
