Solicité el puesto a través de un captador. Acudí a una entrevista en Amazon (Seattle, WA) en mar 2013
Entrevista
Their recruitment agent found me on LinkedIn and sent me an email inviting me to a phone interview with them. The first interview wasn't so bad. They asked about OOP, sorting, and tree traversal questions. There was some coding done on collabedit.
I heard back from them a week later asking for a second phone interview. The second interview was similar to the first, in which they have a question to see if you are familiar with different data structures, run times and regex.

Finding phone numbers of a given format inside large number of different HTML files
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.
