It started around 11 Am on MS teams.
There was only 1 interviewer.
The interviewer asked questions from almost every concept, whatever I mentioned in my resume.

Data Structure and Algorithms: Complete heap Sort(Full code on pen and paper), check a number is a power of 2 or not, and some follow-up questions on data structure and algorithms.

OS: Scheduling algorithms, Round Robin(implementation), Process States, and some follow-up questions on that also.
OOPS: Virtual Functions, Copy Constructors, Runtime Polymorphism, Destructors with their implementation, and lots of follows up questions on that also. They gave more focus on oops concepts in c++ only. If you know oops concepts in c++ then you should be able to explain them well with proper implementation.
Project: Complete description, Database schema(Complete diagram on paper), Data flow diagram, and which technology used in projects. My project was on spring boot based web application with proper database design. They asked many questions related to the flow of the project and request methods(POST, PUT, UPDATE, DELETE).
And some other basic questions on projects as well. The duration of this round was almost a complete hour. 7 students shortlisted after 1 round.

Ninja loves playing with numbers. So one day, he wants to arrange a few numbers in the ‘N’ number of rows. The first row contains 1 number, the second row has two numbers, the third row has 4 numbers, and so on.

Ninja starts placing numbers in increasing order, with absolute difference 1, starting from 1 and continuing till he encounters 9, and then he again restarts from 1.

You are given an integer ‘N’ denoting the given number of rows. Can you print the pattern Ninja wants to create?
