The process took 1 day. I interviewed at Amazon (Seattle, WA) in Feb 2012
Interview
Met Amazon representative at university career fair where they had me answer a small programming question. About a week later I received an email about an interview opportunity in seattle. I had the option to choose the most convenient date out of list.
In Seattle, I went through 4 technical interviews, about 45min each. They some simple algorithms questions such as tree traversals, binary search.
Interview questions [1]
Question 1
Given a tree, output a linked list of all nodes in the tree ordered by level. For example, root, then all nodes at the next level, then the next.
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.

Question 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.
