Tech Mahindra Technical Interview Questions With Answers

Tech Mahindra is one of the leading IT service providers, known for offering exciting career opportunities to freshers and experienced professionals alike. Cracking the Tech Mahindra Technical Interview Questions requires a strong grasp of programming concepts, data structures, algorithms, and core technical subjects. Whether you are preparing for a software development role or a technical support position, practicing Tech Mahindra Technical Interview Questions can significantly boost your chances of success.

Below are 10 commonly asked technical interview questions with detailed answers.

1. What is the difference between C and C++?

C is a procedural programming language that focuses on functions and structured programming. It does not support object-oriented programming (OOP) concepts like classes and objects. On the other hand, C++ is an extension of C that includes OOP features such as encapsulation, inheritance, and polymorphism, making it more flexible for software development. Additionally, C++ supports function overloading, operator overloading, and exception handling, which are absent in C.

2. Explain the core OOP concepts in Java.

Java follows the object-oriented programming (OOP) paradigm, which includes four key concepts. Encapsulation ensures data hiding by restricting direct access to variables through private access modifiers and getters/setters. Inheritance allows a child class to acquire properties and behaviors from a parent class, promoting code reuse. Polymorphism enables the same method to behave differently based on the object that invokes it, implemented through method overloading and method overriding. Abstraction hides the implementation details of a class and exposes only necessary functionalities using abstract classes or interfaces.

3. What is the difference between an abstract class and an interface in Java?

An abstract class in Java can have both abstract (methods without a body) and concrete methods (methods with implementation). It allows partial implementation of functionalities that subclasses can extend. An interface, on the other hand, defines only method signatures (before Java 8) and does not contain implementation. It is used to achieve complete abstraction and multiple inheritance. Java 8 introduced default and static methods in interfaces, allowing some level of implementation. Unlike abstract classes, interfaces support multiple inheritance, making them a preferred choice in large-scale applications.

4. What is a deadlock in operating systems?

A deadlock is a situation in operating systems where two or more processes are stuck in a state of indefinite waiting because each is holding a resource that the other needs. Deadlocks occur due to four conditions: mutual exclusion (only one process can use a resource at a time), hold and wait (processes holding resources can request additional resources), no preemption (resources cannot be forcibly taken away), and circular wait (a set of processes form a cycle where each process waits for a resource held by another process in the cycle). Deadlocks can be avoided by using resource allocation strategies like deadlock prevention, avoidance (Banker’s algorithm), or detection and recovery.

5. What is the difference between SQL and NoSQL databases?

SQL databases are structured and follow a relational model where data is stored in tables with predefined schemas. They use Structured Query Language (SQL) for querying and are suitable for applications requiring strong consistency, such as banking systems (e.g., MySQL, PostgreSQL). NoSQL databases, in contrast, are non-relational and store data in formats like key-value pairs, documents, graphs, or wide-column stores. They offer flexibility, scalability, and faster performance for handling large amounts of unstructured data, making them ideal for big data applications (e.g., MongoDB, Cassandra).

6. What is normalization in databases?

Normalization is a database design process that eliminates redundancy and ensures efficient data organization. It involves multiple normal forms (NFs). First Normal Form (1NF) removes duplicate columns and ensures each column contains atomic values. Second Normal Form (2NF) eliminates partial dependencies, ensuring that all attributes depend on the primary key. Third Normal Form (3NF) removes transitive dependencies, ensuring that non-key attributes depend only on the primary key. Higher forms like Boyce-Codd Normal Form (BCNF) further refine database integrity. Normalization improves data consistency and minimizes anomalies in database operations.

7. What is the difference between a stack and a queue?

A stack is a data structure that follows the Last In, First Out (LIFO) principle, meaning the last element added is the first one to be removed. It is used in applications like function calls (call stack) and expression evaluation. A queue, on the other hand, follows the First In, First Out (FIFO) principle, meaning the first element added is the first one to be removed. It is used in scenarios like task scheduling and handling requests in a system. While stacks are implemented using arrays or linked lists with push() and pop() operations, queues support enqueue() (adding elements) and dequeue() (removing elements).

8. What is Agile methodology?

Agile is a software development methodology that emphasizes iterative progress, collaboration, and customer feedback. It follows principles from the Agile Manifesto, focusing on flexibility and incremental delivery. One of the most popular Agile frameworks is Scrum, which divides development into time-boxed iterations called sprints (usually 1-4 weeks long). Agile promotes daily stand-up meetings for team coordination and continuous integration to ensure faster software development. Agile methodologies like Scrum and Kanban improve project adaptability and team collaboration, making them widely used in IT industries.

9. What is a memory leak in C++?

A memory leak occurs in C++ when dynamically allocated memory is not deallocated, leading to increased memory usage and potential system crashes. This usually happens when a program allocates memory using the new keyword but fails to release it using delete. For example:

void memoryLeak() {
int* ptr = new int(10); // Allocating memory
// No delete statement, leading to a memory leak
}

To prevent memory leaks, it is essential to explicitly deallocate memory using delete ptr; or use smart pointers like std::unique_ptr and std::shared_ptr in modern C++.

10. What is the difference between TCP and UDP?

Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are communication protocols used in networking. TCP is a connection-oriented protocol that ensures reliable data transmission by establishing a connection before data transfer. It guarantees data integrity through acknowledgments and retransmission of lost packets, making it suitable for applications like web browsing and emails. UDP, on the other hand, is a connectionless protocol that sends data without ensuring delivery, making it faster but less reliable. It is commonly used in applications like video streaming and online gaming, where speed is prioritized over accuracy.

Tech Mahindra Interview Questions for Software Developer Role

For aspiring software developers, Tech Mahindra interview questions will likely focus on your technical skills and problem-solving abilities. Here are some common interview questions for freshers applying for software developer positions:

What programming languages are you proficient in?

Answer: “I’m proficient in Java, Python, and C++ programming languages. I’ve used these languages extensively in my academic projects and internships. For example, I developed a [brief description of a relevant project] using Java, which helped me understand object-oriented programming principles in depth.”

Explain the difference between an abstract class and an interface.

Answer: “An abstract class is a class that cannot be instantiated and may contain both abstract and concrete methods. It’s used when you want to provide a common base class implementation to all the subclasses. On the other hand, an interface is a contract that specifies a set of abstract methods that a class must implement. It’s used to achieve multiple inheritances and to define a common behavior that can be implemented by unrelated classes.”

What is the difference between stack and heap memory?

Answer: “Stack memory is used for static memory allocation and is used for local variable storage. It follows a Last-In-First-Out (LIFO) order and is typically faster but limited in size. Heap memory, on the other hand, is used for dynamic memory allocation and is managed by the programmer. It’s slower than stack memory but can store larger amounts of data and is used for objects and variables with a longer lifetime.”

Explain the concept of multithreading.

Answer: “Multithreading is a programming concept where multiple threads run concurrently within a single program. Each thread represents an independent flow of execution, allowing a program to perform multiple tasks simultaneously. This can improve performance and responsiveness, especially in applications that involve I/O operations or complex computations. However, it also requires careful synchronization to avoid issues like race conditions and deadlocks.”

How would you approach debugging a complex software issue?

Answer: When debugging a complex issue, I would follow these steps:
