Initially, I was asked to introduce myself. Then, he proceeded to ask me a bit about my resume and projects. I was asked to go in-depth into one of the projects and explain its workings and answer some questions about it.

For my expense categorization app, I had used the XGBoost algorithm, which he asked me to explain. He asked one simple DSA question: Given n, find the nth Fibonacci number using recursion, which I was able to do in a couple of minutes.

He asked a lot of questions about OOPs and requested that I write code in any language demonstrating the major concepts of OOPs, such as encapsulation, polymorphism, abstraction, and inheritance. Since I hadn't revised OOPs before the interview, I wasn't able to fully answer these questions.

He also asked a few behavioral questions, even though this was supposed to be a purely technical interview. In the end, he asked a logical question: Given two jugs with capacities of 5 liters and 3 liters, how can we measure 4 liters? I was able to solve it without much difficulty.
