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.
The process took 1 day. I interviewed at Amazon (Seattle, WA) in Nov 2011
Interview
I had already gone through one phone screen which went very well. I was contacted via email by my recruiter to set up an onsite interview. I was in Seattle, WA for 3 days, 2 nights in a nice hotel not far from HQ in the heart of downtown Seattle. The interview was administered on the second day. It went from 11-4 and included 5 1:1 interviews—including the non-technical, hiring manager interview during lunch. Aside from the lunch interview—which was one hour long—all of the interviews were 45 minutes long. Amazon lives up to the reputation of administering difficult interviews. I was asked design questions, algorithm questions, language-specific knowledge questions, and various other questions.
All in all, I really enjoyed the experience. The people I met were genuine and real. It was obvious that you could simply be yourself at Amazon; from your opinions to your clothing, they not only allow you to be yourself, the demand it.

Question 1
Write a function that takes an integer and counts the number of bits.
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.
