Tech Mahindra Interview Questions 

Tech Mahindra Technical Interview Questions 

1. What is your experience with programming languages like Java, Python, or C++?

I am experience with Java and C++.

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

The last item added to the stack is the first thing deleted in a stack, which is a type of data structure that adheres to the Last-In-First-Out (LIFO) concept. On the other hand, a queue operates according to the First-In-First-Out (FIFO) principle, where the first thing added to the line is also the first thing taken out.

3. Explain your experience with database management systems, such as MySQL or Oracle.

In my past positions, I used both Oracle and MySQL. I have expertise in creating sophisticated SQL queries and stored procedures as well as developing, implementing, and optimising database structures.

4. What are the different types of sorting algorithms?

Insertion sort and bubble sort are both sorting algorithms used in programming. Insertion sort works by comparing each element in an array to the elements before it, and inserting it into the correct position in the sorted subarray. Bubble sort works by repeatedly swapping adjacent elements if they are in the wrong order until the entire array is sorted.

5. How would you approach debugging a complex software program?

To debug a complex software program, I would start by reviewing the code and the error messages to understand the root cause of the issue. I would then use a combination of print statements and debugging tools to isolate the problem and identify the specific lines of code that are causing the issue.

6. Explain constructor.

Java's constructor function is used to initialise a class's objects. There is no return type and the constructor has the same name as the class. If a class object is created, it is immediately called. A constructor's primary function is to initialise the object's variables to their default values.

7.Explain finalize() method in Java.

When an object is going to be destroyed, the garbage collector in Java calls a particular method called finalise(). Before the object is garbage collected, any cleaning tasks are carried out using the finalise() function.

8.What are the ACID properties in Database Management system?

Atomicity, Consistency, Isolation, and Durability are together known as ACID. These are the core characteristics of a database management system that guarantee transactions are reliably executed.

• Atomicity: ensures that a transaction is processed as a single, indivisible unit. 
• Consistency: ensures that the database remains in a consistent state before and after the transaction. 
• Isolation: ensures that concurrent transactions do not interfere with each other. 
• Durability: ensures that once a transaction is committed, its changes are permanent and cannot be undone.

9. Explain JVM.

The Java bytecode is executed by a virtual machine. The JVM offers a setting that is independent of the operating system and hardware. It is in charge of loading the classes, running the bytecode, and managing memory.

10. Explain different types of classloaders in Java.

In Java, there are three different classloader types:

• Bootstrap Classloader: This component of the Java Runtime Environment (JRE) is in charge of loading the fundamental Java classes.

• Extension Classloader: This programme is in charge of loading the JRE extensions' classes.

• The system classloader is in charge of loading the classes found on the user-defined classpath.

11. List out benefits of Java packages?

There are some benefits of Java Packages:

• Modularity: Packages help to organize the code into logical modules, which makes it easy to maintain and reuse.
• Namespace management: Packages provide a way to avoid naming conflicts between classes.
• Access control: Packages provide a way to restrict the access to the classes and their members.

12. Explain different stages of process in the database management system.

The stages are as follows:

• New: Create or initiate new process
• Ready: The process is ready to start the execution.
• Running: Process is executing at this stage.
• Wait or block: Process is waiting to execute another process.
• Terminate: When process is completely executed it goes into terminate state.

13. What is multithreading?

Programming technique known as multithreading enables numerous threads of execution to operate simultaneously within a single programme. The operating system schedules each thread for execution, and they each operate independently.

14. What is transparent database management system?

A transparent database management system is one that obscures the user from the complexity of the database. The database is accessible through a straightforward interface, so the user is not need to be familiar with the underlying data structures.

15. What is cloud computing?

A shared pool of technology resources, such as servers, storage, applications, and services, may be accessed on-demand over the internet using the cloud computing approach.
