Me postulé en línea. El proceso tomó 4 meses. Acudí a una entrevista en Amazon (Luxemburgo) en ene 2014
Entrevista
The whole process was very well organized by the recruiter. All the people were very friendly and made me feel at ease, both during phone interviews and during on site interviews. Unfortunately, after about a month and a half, I received an email saying that I would not be in.
It was a good experience anyway.

5° (SDE)
- Solving a Puzzle that involves graphs search
- Write BFS code on a whiteboard
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.
