Me postulé en línea. El proceso tomó 2 meses. Acudí a una entrevista en Amazon (Seattle, WA) en abr 2014
Entrevista
Applied online and then quite a while later (1-2 months) I got an email inviting me to come to Seattle for an on-site interview. There was no phone interview or anything like that. The day of the interview, all the candidates were split into groups of 3 and we were given a problem to complete, which was very clearly separated into 3 parts. All of the parts involved some sort of minimization problem and one of them, the one I chose, involved making predictions based on historical data and then minimizing costs based on the prediction. I got the impression that they kind of wanted us to work together but the problems weren't too related to each other and they said that we were not supposed to do any pair programming so that didn't really happen. We just worked on our problems and then periodically had short meetings with Amazon engineers to talk about our progress (I think there were 3 of these throughout the day). At the end, we submitted our code and then had a short info session with some more engineers and that was it.
Overall, it was a pretty good way to do interviews, I think. Definitely gave them a lot more info about my skills than most interviews do.

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.
Um teste de código online, se aprovado, vai para o loop. O loop é 4 entrevistas seguidas, duas em inglês e duas em português. 3 entrevistas técnicas de código, todas as 4 têm pergunta de liderança.
