Tech Mahindra Interview Questions
Now, Let us explore the top 15 most asked tech Mahindra interview questions that will help you to ace your interview with confidence. These list of tech mahindra interview questions is specially prepared by our experts after thorough research and analysis.
1) What programming languages do you know?
Ans: I am good at using Java, Python, and C++. I’ve worked with these languages a lot in my college projects and internships. For example, I created a [brief description of a relevant project] using Java, which helped me in learning more about the concept of object-oriented programming, libraries of Java, and much more.
2) What’s the difference between an abstract class and an interface?
Ans: An abstract class is a type of class that cannot be used for creating objects, and it can have both complete and incomplete methods. It’s useful when you want to have a basic setup for other classes. An interface, on the other hand, is like a list of methods that a class must include, but it doesn’t have any actual code inside those methods. It is used to allow different classes to share the same abilities, even if they’re not related.
3) What’s the difference between stack memory and heap memory?
Ans: Stack memory is used for storing local variables and works on a simple principle of Last-In-First-Out, where the last thing added is the first one to be removed. Heap memory on the other hand is used for storing data that needs to last longer, like objects. It’s bigger and managed by the programmer, but it’s slower than stack memory.
4) What is multithreading?
Ans: Multithreading is when a program runs several tasks at the same time, each in its own thread. This generally helps the program to do more things at once, which can make it run faster and be more responsive, especially when dealing with tasks like reading data or doing complex calculations. But you have to be careful to make sure the threads don’t interfere with each other, which can cause problems like race conditions or deadlocks.
5) How do you debug a difficult software problem?
Ans: It is a among one of the widely asked tech Mahindra interview questions which is often asked in technical round. To debug a tough problem, I would:
- Find out exactly where the problem is happening and separate the whole code from that part of the code.
- Use tools to stop the code at certain points and go through it step by step.
- Look at the values of variables at different points in the code.
- Check multiple logs for error messages or strange behavior.
- If needed, add print statements to track the flow of execution.
- Once I know what’s causing the problem, I’ll fix it and test it thoroughly.
- Will note it down what went wrong and how I fixed it for future reference.
6) What is normalization?
Ans: Normalization is a process used to organize data in a database. It involves creating tables and defining relationships between them. The goal of normalization is to eliminate redundancy (duplicate data) and ensure that the data is consistent and flexible for future changes.
7) What are stack, queue, array, and linked list?
Ans: Stack: A stack is a linear data structure where elements are added and removed in a specific order. It follows a principle of last in, first out (LIFO). You can understand stack better by comparing it to the stack of plates where you will add plate at the top and will also remove it from the top.
Queue: A queue is a data structure that follows the principle of first-in, first-out (FIFO). In this case, Items are added at one end and removed from the other. You can consider this as a line of people waiting their turn where the very first person who got in was the first one to get out.
Array: An array is a collection of elements stored in a specific order where each element is accessed by an index. You can consider this as a row of numbered lockers, where each locker holds a separate piece of data.
Linked List: A linked list is a structure used to store a sequence of data elements called nodes. Each node has two parts: one that holds the data and another that points to the next node in the sequence. This makes it flexible for adding or removing items.
8) What is 3NF in DBMS?
Ans) The third normal form (3NF) is a way of designing a database to reduce duplicate data, avoid errors, and maintain data consistency. Using this form of DBMS helps users to ensure that the data is organized efficiently.
9) What is an operating system?
Ans) An operating system is software that manages the basic functions of a computer, such as handling files, memory, processes, input and output, and controlling devices like printers and monitors. Some of the common operating systems of today’s time include- Windows, MacOS, Linux, etc.
10) What are pointers?
Ans) Pointers are variables that store the address of another variable. They are denoted by * sign and allow you to access as well as manipulate the value of the variable they point to. Different types of pointers include null pointers, void pointers, and wild pointers.
11) Name some object-oriented programming languages
Ans: Here are some examples of object-oriented programming languages:
12) What is a token?
Ans: A token is the smallest piece of a program that helps the compiler to understand what is being written and happening in the program. Different types of tokens include:
13) What is the Java Virtual Machine (JVM)?
Ans: The Java Virtual Machine, or JVM, is a part of Java that loads, checks, and runs Java bytecode. It acts like an interpreter and is like the core part of the Java programming language.
14) What are the advantages of Java Packages?
Ans: Java packages help you to organize classes and interfaces in an organized way. This makes it easier to manage and Protect data against unauthorized access.
15) What is a checkpoint in DBMS?
Ans: A checkpoint in a Database Management System (DBMS) saves all previous logs permanently to storage and clears them from the system. It marks a point where all transactions are completed, ensuring the database is in a stable state.
