Amazon SDE2 interview question

My Amazon SDE2 interview process commenced with an Online Assessment, which covered behavioral questions and standard system design principles.

The second round was dedicated to coding, presenting two distinct challenges. For the first question, I was tasked with identifying the maximum length subarray where the difference between its first and last elements was 'k'. I successfully navigated this problem, progressing from a brute-force approach to an optimal solution within 20 minutes. The second coding challenge involved discovering the maximum product of an L-shaped path within a given matrix. While I required a few hints, I was able to achieve a complete solution. Interestingly, no Leadership Principle (LP) questions were posed during this coding round. I left feeling confident that the interviewer was pleased with my performance.

The third and final round focused on Low-Level Design (LLD). Here, the primary objective was to design a notification system, with a particular emphasis on constructing message content tailored for various communication channels. This round also incorporated two specific Leadership Principle questions.

A week following the interviews, I received a rejection email, devoid of any specific feedback. I found this outcome quite surprising, as I believed my performance was strong. It really highlights how incredibly high the interview bar is these days.
