La procedura ha richiesto un giorno. Ho sostenuto un colloquio presso Amazon (Seattle, WA) nel mese di lug 2011
Colloquio
They sent me an email stating that they would like to set up an interview for the position of Software Development Engineer I. Seemed like they were pretty adiment about interviewing me because this was the second person that tried to interview me over about a month. The phone interview was technical in nature. They asked questions about Data Structures, Algorithms, Object Oriented Programming and Design (at Amazon they primarily use C++, Java, Perl, Ruby), and Problem Solving. The final part of the interview was a coding exercise. The interview in total lasted about 45 minutes.

Domanda 1
Say you had a dictionary of words. How would you set it up? And what would you do if you needed to search for a word (what type of search)? About how long would it take for you to search for the word using Big O notation?
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.

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
