J'ai postulé via un recruteur. Le processus a pris 3 jours. J'ai passé un entretien chez Amazon (Los Angeles, CA) en juil. 2012
Entretien
The interview was over the phone and used a collaborative document to allow me and the interviewer to see what each other was typing. This document was also used to share code. The interview was almost entirely technical, feeding me one problem after another.
First, they asked me about Fibonacci number sequences to see if I knew anything about them and whether I could construct a method to calculate any number in the sequence by inputting what number it was in the sequence (e.g. 1 for the 3rd number, 3 for the 5th number). This was solved using a recursive solution due to the Fibonacci sequence being a recursive sequence, but the interviewer also suggested that there were non-recursive methods. He asked me to generate test cases for the method I just created.
Next, the interviewer wanted me to create a structure that represents a binary search tree and write a boolean function that verified to see whether a parameter was a binary search tree.

Question 1
The interviewer wanted me to create a structure that represents a binary search tree and write a boolean function that verified to see whether a parameter was a binary search tree.
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.

Question 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.
Questions d'entretien [1]
Question 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
