The process took 3 weeks. I interviewed at Amazon (Seattle, WA) in Aug 2011
Interview
My interview consisted of two phone interviews separated by a week and then a final contact a week later telling me that they were going with other candidates. The interviews focused primarily on programming and general development knowledge.
The questions are listed below.
The interviewers were very helpful in describing the problem if you didn't understand the specifics and would ask you to look at specific areas of your code and see if you could improve it. All-in-all it was a good if stressful experience. I am not certain exactly what qualities they are looking for, but I would suggest a month of brushing up on your algorithms and general CS knowledge before you apply unless you are some sort of coding god. Good luck!

Question 1
The difference between and interface and an abstract class
Using only putchar how would you print out the ascii values for each digit in an integer. For example if the integer was 123, then you would want to print the ascii values for 1, 2, and 3.
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.
