The interview process was rigorous and well-structured.

It began with an online coding assessment, which focused on data structures and algorithms.

After clearing that round, I was invited for a series of technical interviews, where I was tested on my problem-solving skills, system design, and understanding of core CS concepts.

The final round included a behavioral interview, where they assessed my ability to handle ambiguous situations and my alignment with Amazon's leadership principles.

Overall, the interviewers were friendly and provided timely feedback.
