Solicité el puesto a través de un captador. El proceso duró 1 día. Acudí a una entrevista en Amazon (Seattle, WA) en may 2010
Entrevista
The recruiter from amazon contacted me and then arranged an interview on the phone. The interviewer was a manager looking to hire in this team. Interview lasted for 1 hour and was mostly about data structures and algorithms. Following questions were asked (1) An array of integer in which all numbers occur even times except for one number occurs odd times, find it. (2) Given 2 strings write a function which returns boolean whether all characters in first string occur in second string.

Given an array of integer in which all numbers occur even times except for one number occurs odd times, find it.
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.

Pregunta 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.

Pregunta 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
