i. Tech Mahindra Technical Interview Questions for Freshers
Starting your career at Tech Mahindra requires a strong foundation in technical concepts and the ability to learn and adapt quickly. Here are 15 Tech Mahindra company interview questions for freshers that you might face in your interview:
Q1. Explain the difference between #include <file> and #include “file”.
Answer: In C and C++, #include <file> is used to include system header files. Whereas, #include “file” is used to include user-defined header files. The angle-bracket (< >) form is used to include standard library files. The quote (“ “) form is used to include files from the current directory or the specified path.
Q2. Explain inline functions in C++ and C. Give an example of an inline function in C as well.
Answer: An inline function in C++ and C is a special function that the compiler may (but is not guaranteed to) substitute directly at the point where they are called in your code. This means that, instead of making a separate function call, the compiler might simply copy the function’s code into the calling location.
This can improve performance by reducing the function call overhead. Here’s an example of an inline function in C:
inline int max(int a, int b) {
return (a > b) ? a : b;
}
Q3. What do you know about C++ or C tokens?
Answer: In C and C++, tokens are the smallest individual units of a program, such as keywords, identifiers, constants, and operators. They are the building blocks of a program and are used to form expressions, statements, and other program elements.
Q4. How would you avoid structure padding in the C language?
Answer: To avoid structure padding in C, you can use the `#pragma pack` directive to pack structure members without any padding. For example, `#pragma pack(1)` will pack the structure members on a one-byte boundary, effectively avoiding padding.
Q5. What exactly do you mean by Function Overloading in C++?
Function overloading in C++ refers to having multiple functions with the same name but different parameters. This allows a function to perform different operations based on the input. For example, you can have multiple `print` functions that take different parameter types, like `int`, `float`, or `string`.

Q6. What do you mean by a checkpoint concerning database management systems?
Answer: In the context of database management systems, a checkpoint is a point in the transaction log sequence at which all data files have been updated to reflect the information in the log. This ensures that in the event of a system failure, the database can be recovered to a consistent state.
Q7. What exactly are ‘Transparent Database Management Systems’?
Answer: Transparent Database Management Systems (TDBMS) are systems that provide a uniform interface to access and manipulate data stored in various databases. They hide the heterogeneity of the different underlying databases from the user, providing a single, consistent view of the data.
Q8. In Java, what is the default value of the local variables?
Answer: In Java, the default value of local variables is not assigned by the system. Therefore, they must be explicitly initialized before use. If a local variable is used without being initialized, the code will not compile.
Q9. State some advantages of Java Packages.
Answer: Java packages offer several benefits, including modularity, encapsulation, and namespace control.
- Modularity: It refers to the ability to organize code into separate and manageable units.
- Encapsulation: It allows packages to hide the implementation details of classes, providing a clear separation of concerns.
- Name Space Control: It prevents naming conflicts by grouping related classes and interfaces under a single namespace.
Q10. Can we define the main() method as private in Java?
Answer: No, the `main()` method in Java cannot be defined as private. It must be defined as public since it is the entry point for the Java application. The Java Virtual Machine (JVM) calls the `main()` method to execute the code in the application.
Q11. What is ‘NullPointerExceprion’? Give an example.
`Answer: NullPointerException` in Java is a runtime exception that occurs when a program tries to access a reference variable that has a `null` value. For example,
String str = null;
int length = str.length(); // This will throw a NullPointerException
Q12. Why do we need Java?
Answer: Java is needed for its platform independence, object-oriented nature, robustness, security, and wide range of libraries and frameworks. It is used for developing a variety of applications, including web, mobile, enterprise, and embedded systems.
Q13. What is Polymorphism? Can we use the return type in the constructor?
Answer: Polymorphism in Java is the ability of a single reference variable to point to objects of different types. When calling a method through this variable, the specific implementation based on the actual object’s type is used. This offers flexibility and code reusability.
No, constructors in Java cannot have a return type. They are designed to initialize objects and don’t return values like normal methods. Trying to define a return type for a constructor will result in a syntax error. For instance,
Code:
public class MyClass {
// Error: Constructors cannot have a return type!
public String MyClass(String name) { // This line will cause a syntax error
this.name = name;
return "Object created: " + name;
}
private String name;
public static void main(String[] args) {
// This line will not compile due to the error above
MyClass obj = new MyClass("Example");
}
}
Output:
MyClass.java:4: error: constructor cannot have return type
public String MyClass(String name) {
^
1 error
Q14. What do you understand about Servlet Collaboration?
Answer: In Java, a servlet is a Java class that acts as a web server extension. It dynamically processes requests and generates responses. Servlet collaboration in Java refers to the ability of multiple servlets to work together to perform a task. This can be achieved through various methods such as request forwarding, including one servlet’s response in another servlet’s response, and sharing data using the ServletContext or HttpSession.
Q15. How is the ‘finalize’ method in Java used? Illustrate with an example.
Answer: In Java, the finalize method serves the purpose of performing cleanup tasks before an object is garbage collected. The code for the ‘finalize’ method is as follows.
class FileHandler {
private File file;
public void openFile(String path) {
file = new File(path);
// ... open file connection
}
@Override
protected void finalize() throws Throwable {
if (file != null) {
// Close the file connection here
file.close();
}
super.finalize();
}
}
Pro Tip: Practice Java interview questions thoroughly to answer any Java-related questions confidently.

Q16. Given an array of positive integers, write the code to return the differences between the sums of even and odd values in the given array.
Answer: Here’s a Python code to return the difference between the sums of even and odd values in the given array:
def even_odd_difference(arr):
even_sum = sum(x for x in arr if x % 2 == 0)
odd_sum = sum(x for x in arr if x % 2 != 0)
return even_sum - odd_sum
Q17. What is reentrancy in multiprogramming time-sharing systems?
Answer: Reentrancy in multiprogramming time-sharing systems refers to the ability of a program to be interrupted in the middle of its execution. Then safely called again (‘re-entered’) before the previous call had been completed. This is important for ensuring the correctness of concurrent programs and for efficient memory usage
Q18. What do you mean by a Process? Name its different types in the context of computers.
Answer: In the context of computers, a process is an instance of a program that is being executed. Types of processes include:
- Foreground Process: A process that is currently being executed and is in the foreground.
- Background Process: A process that is running in the background without user interaction.
- Daemon Process: A process that runs in the background and is usually initiated by the system.
Q19. Define segmentation and fragmentation in memory management.
Answer: Segmentation is a memory management scheme that supports the user’s view of memory. It divides the user’s view of memory into segments and allocates memory to these segments. Fragmentation refers to the wasted memory space that occurs when memory is allocated but not used efficiently.
Q20. Differentiate between Paging and Swapping in Operating Systems.
Answer: Paging and swapping are both memory management schemes in operating systems. Here are the key differences between paging and swapping:
| Paging | Swapping |
| It is a memory management scheme that eliminates the need for contiguous allocation of physical memory. It allows the physical address space of a process to be non-contiguous. | It is a memory management scheme that involves moving a process from main memory to secondary storage and vice versa. This is done to free up memory for other processes. |
Q21. Explain how you would conduct a load test.
Answer: To conduct a load test, follow these steps:

- Monitor Performance: Track key metrics, such as CPU, memory, and network usage.
- Analyze Results: Identify bottlenecks and areas for improvement.
Q22. How would you implement multithreading in Java?
Answer: Multithreading in Java can be implemented in two ways:
a. By Extending the Thread Class:
class MyThread extends Thread {
public void run() {
// Code to be executed in the thread
}
}
public class Main {
public static void main(String[] args) {
MyThread t = new MyThread();
t.start();
}
}
b. By Implementing the Runnable Interface:
class MyRunnable implements Runnable {
public void run() {
// Code to be executed in the thread
}
}
public class Main {
public static void main(String[] args) {
MyRunnable r = new MyRunnable();
Thread t = new Thread(r);
t.start();
}
}
Q23. Describe the concept of exception handling in Java.
Answer: Exception handling in Java involves using try, catch, finally, and throw blocks to manage runtime errors. try contains code that might throw an exception, catch handles the exception, finally executes code regardless of an exception, and throw manually throws an exception.
Q24. Briefly describe macros in the ‘C’ language.
Answer: Macros in C are preprocessor directives defined using #define. They allow you to define constants or functions that are replaced by the preprocessor before compilation, making code more readable and maintainable.
Q25. What are the different types of JDBC drivers?
Answer: JDBC drivers are categorized into four types:
- Type-1: JDBC-ODBC Bridge Driver
- Type-2: Native-API Driver
- Type-3: Network Protocol Driver
- Type-4: Thin Driver (Pure Java Driver)
Q26. Write a C++ program to print the Fibonacci series up to N numbers.
Answer:
#include <iostream>
using namespace std;
int Fib(int n) {
static int t1 = 0, t2 = 1, nextTerm;
if (n > 0) {
nextTerm = t1 + t2;
t1 = t2;
t2 = nextTerm;
cout << nextTerm << ", ";
Fib(n - 1);
}
}
int main() {
int n = 15;
cout << "0, 1, ";
Fib(n - 2);
return 0;
}
Q27. How will you take a sentence from a user in C?
Answer: To take a sentence as input from a user in C, use:
scanf("%[^\n]%*c", s);Where ^[\n] takes input until a newline is encountered, %*c reads the newline character, and * discards it.
Q28. Can you explain the difference between file structure and storage structure?
- File Structure: The logical organization of data in a file, such as records, fields, and files.
- Storage Structure: The physical organization of data on storage media, including how data is stored in blocks, sectors, and tracks.
Q29. What is FCFS?
Answer: FCFS (First Come, First Served) is a scheduling algorithm where the CPU is allocated to processes in the order they request it. It’s managed by a FIFO queue.
Q30. What is garbage collection in Java, and how does it work?
Answer: Garbage collection in Java is an automatic memory management process that frees memory by removing objects that are no longer in use. It works by:
