Synchronous means happening at the same time, while asynchronous means not happening at the same time.
Synchronous operations occur in real-time, while asynchronous operations can be delayed or queued.
Synchronous operations block the program until they are completed, while asynchronous operations allow the program to continue running.
Examples of synchronous operations include function calls and loops, while examples of ...
CTE and temp table usage in SQL
Use CTE for recursive queries and complex subqueries
Use temp tables for large data sets and complex queries

Dependency injection is a design pattern that allows objects to receive dependencies rather than creating them.
It helps to decouple the code and makes it more testable and maintainable.
It allows for easier swapping of dependencies without changing the code.
There are three types of dependency injection: constructor injection, setter injection, and interface injection.
Example: Instead of creating a database connection ob...

I appeared for an interview in Jan 2021.
Round duration - 90 Minutes
Round difficulty - Medium
This round happened on the same day as JAM in the afternoon time. A slot of 20 minutes with respective timing was already sent to the selected students. Interview can’t be generalize as anything can happen over there and hence this was exclusively my experience.
To have a quick judgement about the person, I believe nothing is better than throwing before him/her some puzzles (mathematical/ analytical/ programming problems) and see the approach. I received back-to-back 4 problems after a quick and brief introduction. The coding problems I got were way too easy (just basics: searching & mathematical). The harder part of this round was the puzzles (tricky, mathematical, related to probability). At last, I was asked a question on DBMS and the interviewer asked if I know JAVA.
Given a sorted array 'A' of 'N' integers, determine whether a number 'X' exists within this array for a series of queries. For each query, print 1 if 'X' exists in the ...
Search for a number in a sorted array and determine its existence for multiple queries.
Use binary search algorithm to efficiently search for each query integer in the sorted array.
For each query integer 'X', check if it exists in the array 'A' and output 1 if found, 0 otherwise.
Ensure the array 'A' is sorted in non-decreasing order to apply binary search effectively.
