I attended a walk-in interview at Oracle Gift City, Gandhinagar. My interview was scheduled for 9:30 AM. There were over 100 people in the queue for interviews, with experience ranging from 3 to 10 years. After verifying my interview offer email, I was assigned a number.

The first round was a technical interview with two interviewers: one software engineer and one project manager. They asked technical questions based on Data Structures and Object-Oriented Programming concepts, including Collections, Generics, Trees, Linked Lists, and Array Lists. Many of the questions were difficult, so please be prepared. The project manager also inquired about my current project and asked a few other questions.

After the technical round, I was given a programming problem: to find a given word within an n*n 2D matrix. Many of the problems asked were similar to those found on GeeksforGeeks. I was not aware of how to solve this particular problem, so I spent 20 minutes attempting it and submitted a solution to the interviewer. He mentioned that HR would call me. At that moment, it was evident from his facial expressions that I had not been selected.
