I applied through a recruiter. I interviewed at Amazon (Seattle, WA) in Oct 2015
Interview
Recruiter reached out to me to schedule onsite. The onsite was the group interview format, where you worked in groups of 3 on a sizable problem that was divided up into 3 parts. The schedule of the day looked like this: intro presentation of Amazon, handed out problem booklet, time to talk over the problems with your group, decide who takes which problem, talk to a proctor about how you want to approach your problem, code, lunch, code, another talk with a proctor on your progress, finish up code. The process was enjoyable and they emphasize leadership principles, so try to show as many as you can during the interview.
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.
