Me postulé a través de una recomendación de un empleado. Acudí a una entrevista en Amazon (Seattle, WA) en feb 2021
Entrevista
Three online assessments, then a virtual onsite, then an offer. This was for the new grad SDE position. After the three online assessments I was originally rejected, but then they reached back out a few months later and gave me an interview
Preguntas de entrevista [3]
Pregunta 1
The first was a generalization of two sum (https://leetcode.com/problems/two-sum/), k sum, with tuples of length k instead of 2, with the assumption that each element is unique. I'd say LC medium.
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.
