The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Apr 2011
Interview
Got a call for first phone interview. Went ok, could answer most of the questions except for one. Give some good solutions. One of the question I was knew already so it wasn't very difficult for me to think. Was skeptical to get a call for second phone interview but I did get a call. The second interview went really very well... a perfect example of excellent interview... answered all the questions with 100% accuracy without a single doubt in mind. The interviewer was happy could make it from the conversation and it ended in 30mins since he said he did not have anymore questions to ask. Well was waiting for an onsite call but got a reject finally. Well my luck didn't turn out well.. Little bit of disappointment.... it happens all the time.
Interview questions [4]
Question 1
Given the list of elements all of them occurring even number of times except for one. Find that number
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.
