Me postulé a través de un reclutador. Acudí a una entrevista en Amazon en sep 2014
Entrevista
I was contacted by a recruiter that viewed my Linkedin profile.
Had a phone interview with a software engineer in Amazon, was asked about my current job and several technical questions.
I was asked to implement two questions on a collaborated web-site (white board).
Preguntas de entrevista [1]
Pregunta 1
1. Implement a method that verifies if one string can be constructed by another. E.g: "aaabc" can be constructed by "aaabbbccd"
2. Given a linked list containing numbers (Node element), implement a method that returns two lists: one containing even numbers and one odd numbers - without allocating new list elements.
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
