The interview began with a detailed review of my resume, so I was expected to be well-versed with everything mentioned. This was followed by questions across multiple core subjects:

Database Management: Normalization and its normal forms, ACID properties

Object-Oriented Programming: Difference between abstraction and interface, and the concept of encapsulation

Operating Systems: Internal vs. external fragmentation, and process scheduling

I was then asked to choose a DSA topic, and I selected Graphs. Based on this, I was asked to:

Write graph algorithms along with their time complexities

Code Dijkstra’s algorithm

Implement Disjoint Set Union (DSU)

Towards the end, there were conceptual questions on LLMs, Generative AI, and Agentic AI, followed by a discussion on whether I had worked on any AI-based projects.

The second round was largely similar in structure to the first. It included:

In-depth, project-based questions

Writing code for the controller, router, and middleware that I had implemented in my project

Problem-solving questions based on Linked Lists and HashMaps
