I applied through a recruiter. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Jan 2012
Interview
Short phone interview, only about 50 minutes long. All the questions were technical, but not too hard. You will also be asked to write some code up on a collaborative editing website where your interviewer watches as you type. You get a chance to ask questions of your interviewer at the end. Amazon is very data-driven, my interviewer worked in a small team doing manipulation and organization of employee and package data for higher ups. Know your data structures and algorithm analysis.

Question 1
You are given two arrays, design a method to produce the intersection of those arrays. Analyze its runtime.
You have a directory tree of plain HTML files and your boss wants you to find all the phone numbers on the pages so they can be removed. What would you use to do this?
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.
