The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Mar 2012
Interview
The first round was okay, I applied through my college job portal and was asked by mail to schedule a phone interview. All the questions asked were basic and I passed that round.
I was asked to schedule a second interview and when it was time for it I was prepared and all but did not get a call, I mailed them inquiring about the interview , they apologized and rescheduled it. This time I received a call. They asked about Java Generics and Dynamic mapping etc. Later programming question was about finding repeated alphabets in a sequence. They did not like my logic and approach to the program.
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.
Interview questions [1]
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.
