Criteria in Hibernate is used to create and execute dynamic queries.
Criteria is an interface in Hibernate that allows the creation of dynamic queries without using HQL or SQL.
Criteria queries are type-safe and can be easily modified at runtime.
Criteria queries can be used to fetch entities based on certain conditions or restrictions.
Example: Criteria criteria = session.createCriteria(Employee.class);
To create a custom serializable interface, you need to define an interface with the Serializable marker interface and implement the necessary methods.
Define an interface with the Serializable marker interface
Implement the necessary methods for serialization and deserialization
Ensure all fields in the class implementing the interface are serializable

I am currently using Visual Studio Code as my primary tool for software development.
Visual Studio Code is a lightweight and versatile code editor.
It has a wide range of extensions and plugins available for customization.
It supports multiple programming languages and has built-in Git integration.
Other tools I have experience with include Eclipse, IntelliJ IDEA, and Sublime Text.

A process is an independent entity that contains its own memory space, while a thread is a subset of a process and shares the same memory space.
A process has its own memory space and resources, while threads share the same memory space and resources within a process.
Processes are independent of each other, while threads within the same process can communicate with each other more easily.
Processes are heavier in te...
Use multiple threads to print numbers from 1 to 100 in an optimized manner.
Divide the range of numbers (1-100) among the threads to avoid overlap.
Use synchronization mechanisms like mutex or semaphore to ensure orderly printing.
Consider using a thread pool to manage and reuse threads efficiently.

I applied via Approached by Company and was interviewed in Apr 2024. There was 1 interview round.
The first round was named Technical Assessment. It had 34 questions in, total split into 4 sections. The first section was coding section which consisted of 2 questions - 1 easy and 1 medium level basic DSA problems, 2nd section was coding section which consisted of 2 debugging questions easy questions, 3rd section was MCQ for coding/math related questions and final section was logical reasoning.
I think in total it was 100 marks
1st section - 50 marks ( 20 for easy question and 30 for medium question)
2nd section - 20 marks ( 10 each for both questions)
3rd & 4th section 30 marks (1 each for every questions 1*30 =30 )
Interview Preparation Tips
- DSA
- Logical reasoning
- Debugging
I couldn't crack the first round as I only prepared for aptitude, I did not expect coding rounds.
I couldn't complete the coding round as time ran out got the logic and all but couldn't complete.
So my advice would be to prepare very well for the coding as it has the highest weightage, I did everything except coding so I guess the cut off would be somewhere around 60 -70 marks.
Just study the basic DSA problems like array, strings , maps ,set and that's more than enough.
Also study all loop patterns like Floyd's triangle etc.
For programming language if you are good at Javascript its enough as the code they gave was much more readable in Javascript.
If you want you can study C++ or java for this if you are going with C++ make sure you study C++ STL and memory management concepts and pointers. If you are going with Java study the Java Collection framework as it is a necessary.
Then just revise your college lab programs like fibonnacci, factorial, palindrome etc..
Then for logical reasoning be good with decryption questions like if MUSEUM is coded as LSPAPG these type of questions, then be good with finding the next number in pattern in a grid etc.
Also practice some coding MCQ questions as well.

- Q1. What is event loop in js
- Ans.
Event loop in JavaScript is a mechanism that allows asynchronous non-blocking behavior by handling events and callbacks.
Event loop is responsible for handling asynchronous operations in JavaScript.
It allows JavaScript to perform non-blocking operations by queuing tasks in a loop.
Event loop continuously checks the call stack and the task queue, moving tasks from the queue to the stack when the stack is empty.
Example: se...
