Ho presentato la mia candidatura tramite l'università. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Amazon nel mese di mar 2010
Colloquio
I had two rounds of 45min-phone interviews from amazon. They are all technical interviews, only the first one involves 1 question about my project that is not that technical. Other than that, all coding questions!
Depending on your coding speed, he/she will ask you about 2-3 questions. he/she usually starts by asking you to write an algorithm and then asks for runtime/space complexity, then asks if you can do better.
You might expect to read all your code to the interviewer, or he/she might send you a link to online notepad so that he/she can see you typing.
Overall the experience is pretty good.
Domande di colloquio [2]
Domanda 1
How to find the unique integer in an array, where all the other numbers appear twice.
Surprisingly easy — I expected tougher questions, but the coding round felt more like a warm-up. The main challenge was a DSA problem about counting islands in a 2D grid, which led to a discussion on DFS versus BFS and handling large grids. Funny enough, I had revisited that exact type of question while prepping on PracHub, which made me feel more confident. The interview wrapped up with a behavioral round, and I accepted an offer, but ultimately decided to decline it for another opportunity. Overall, it was a smooth experience.

Domanda 1
Number of Islands — given a 2D grid of '1's (land) and '0's (water), count the number of connected islands. Walk through DFS vs BFS, and discuss how to avoid revisiting cells (in-place mutation vs visited set) and what changes if the grid is huge and must stream from disk.
It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.

Colloquio
Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.

Domanda 1
The first question is LeetCode style algorithms question, and the second question gives a full stack repo (choice of Java, NodeJS, or Django) and asks to solve a backend issue which is causing a bug in the frontend. Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
