I applied through an employee referral. The process took 4 weeks. I interviewed at Amazon (Arlington, VA) in Oct 2021
Interview
Overall was a very enjoyable interview process. Every recruiter/interviewer I talked to made sure I wasn’t confused about anything and had all the information I needed. Interviews were difficult but gave plenty of opportunity to exhibit my competence and personality. I was given an online assessment which consisted of two coding questions that lasted about 40 minutes each. Both LC medium level. After the assessment I was contacted a week or so later for a final round interview, which was scheduled two weeks later. Consisted of four rounds of hour long interviews which were partially behavioral, partially technical. Got an offer five days later.

Question 1
I signed an NDA so I can’t reveal the exact questions but they’re typical interview questions.
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.
