Round by round

1. 1

   The first round was purely DSA. I was given two medium-level problems ,one on dynamic programming and another on sliding window techniques. Both required careful thinking, but I was able to code them successfully and explain my approach to the interviewer.

2. 2

   The second round focused on Java and Low-Level Design. I had to design the database and basic LLD for a ticket booking app, similar to IRCTC. In addition, the interviewer asked questions on the Collections framework, Hibernate, Spring Boot, and some core Java concepts. It was a mix of theoretical and practical discussions.

   The third round was a High-Level Design round where I was asked to design an e-commerce application.

I presented functional requirements, non-functional requirements, the architecture, and API design while addressing potential edge cases.
