In February, I had two rounds of interviews where I got to solve challenging problems and engage in technical discussions:

• Round 1 – Data Structures & Algorithms: Min-Heap, Generate All Valid Parentheses, followed by a Leadership Principle (LP) discussion.
• Round 2 – A mix of Operating Systems, Networking, and DSA, including Spiral Matrix traversal and Implementing Queue using Stacks.

Despite giving my best, I received a rejection email on March 10th. While the outcome was not what I had hoped for, I see this experience as a huge learning opportunity. The process pushed me to improve my problem-solving skills, dive deeper into core CS concepts, and gain firsthand experience of Amazon’s interview structure.
