Ho presentato la mia candidatura online. La procedura ha richiesto un giorno. Ho sostenuto un colloquio presso Amazon (Austin, TX) nel mese di lug 2014
Colloquio
Apply online one day and got a feed back in less than 24 hours. The recuriter sent an email with instructions on the position, tips to perpare you for the test, and the link to take the test. Had to take a 60 minute test before continuing. The test contains some logical questions and especially heavy on data structures.

Domanda 1
Hardest question was the first one. It asks you to write a program that will allow the user to create lines, rectangles, circles, text, etc. And allow them to manipulate them independently (move them, resize them, etc.) Design an object model for this application. (How would you model the representation of the document in an object oriented language? What classes would you define? What methods would you have? What would your API look like?)
The second question ask you to code the following about facebook: Direct friends of m are Level 1 friends. Friends of friends are level 2 friends.....and so on
Print level 1 friends first. Then print level 2 friends....and so on
The third and final question was the follow: Write an efficient function that returns the n’th Fibonacci number (There are many ways to solve this problem. Please write the most efficient method possible). Each Fibonacci number is the sum of the last two. The first 10 are: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55
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
