I applied online. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Feb 2011
Interview
Applied online through the local campus career center. Initially was supposed to have an on-campus interview although due to extenuating circumstances, some of these interviews were canceled. Spoke with recruiting and was later scheduled for two phone interviews scheduled. The hiring process consisted of two back-to-back interviews each 45 minutes in length. The first interviewer was straight down to business and asked me some programming questions while the second one took some time to answer any questions I had about the company before asking me some programming as well as design and behavioral questions. Both interviewers were courteous and gave me the time I needed to solve the presented problems. One piece of advice I would offer is to verbalize your thoughts when attempting to solve a problem so that the interviewers can get a feel for your thought process and nudge you in the right direction if you are a little stumped on a particular question.

Question 1
What do you know about Binary Trees? Write a function that outputs the contents of a Binary Tree to a text file. Write a function that parses from a text file and creates a Binary Tree.
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.
