Solicité el puesto a través de un captador. El proceso duró 2 semanas. Acudí a una entrevista en Amazon en sept 2014
Entrevista
I missed a hiring event earlier in the week, but a friend referred me to a recruiter that contacted him earlier last month. I emailed her and had a brief conversation to ask what I'm currently doing at my job and why I'm looking to leave. Afterwards, she set me up with a 90-minute remote interview using collabedit.com. She recommended using www.topcoder.com and www.careercup.com to prepare for the interview.
Almost a week later, I had the phone/ coding interview:
1. Find the intersection of two arrays
a. What's the time and space complexity?
b. Can you improve performance? i.e. What if arrays were sorted?
c. Which sort would you choose?
d. What if provided and unknown number of arrays?
2. Given a binary search tree, write a method to add a new node to the tree (without re-structuring)
P.S. I heard from a fellow Amazon friend that they are changing up the interview process, so I'm not sure if this is what it's moving to since he said that he had 2 45-minute interviews before proceeding to the on-site interview.
Preguntas de entrevista [1]
Pregunta 1
What's your favorite programming language and why?
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
