Me postulé en línea. El proceso tomó 2 semanas. Acudí a una entrevista en Amazon (Seattle, WA) en nov 2012
Entrevista
This was an entry-level position, specifically for the Amazon Fulfillment team. I had two phone interviews that I thought went really well, but no offer. Basic algorithm and computer science questions. One coding problem to solve each interview. Both interviewers were nice and easy to work with. Like I said, I thought I did really well, but apparently not. So don't get your hopes up too much, even if you're a female/minority and are good enough to receive two phone-interviews. It doesn't mean anything.

None of the questions were difficult. First interview question was about an array and finding all pair values that add up to a target number. Second question was, given an array, find as many permutations as possible in randomly ordering the array.
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.

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.
