Interview Process
The Amazon onsite interview was quite rigorous and consisted of multiple rounds spread across several hours. The first round was behavioral, where the interviewer asked me to elaborate on my past experiences, particularly focusing on how I handled challenges and worked within teams.
Following the behavioral round, I had two technical rounds. The first technical interview involved coding questions related to data structures and algorithms. I was given a question on binary trees and asked to implement a function to find the lowest common ancestor. I used a depth-first search approach to find the solution, which the interviewer appreciated.
In the second technical round, I faced system design questions. I was tasked with designing a URL shortener service and had to discuss the components such as database schema, caching, and load balancing. The interviewer was keen on understanding my thought process and design decisions.
Finally, I had a wrap-up session with the hiring manager who also assessed my fit for the company culture. Overall, the interview was challenging but also enlightening. I received positive feedback for my problem-solving ability and communication skills. I am now waiting for the final decision.
