I applied online. The process took 2 months. I interviewed at Amazon (Tokio) in Mar 2022
Interview
I applied around December 2021 and got an OA email on Februrary.
After passing the OA, I was invited to final interviews (1 hr x 3) at the end of February and I had roughly one month to prepare for the interview.
Around 3 days after the final interviews, they sent me an "unofficial" job offer (since Japan's regulartion is a bit weird) via email.

Question 1
Cannot describe in detail due to NDA.
For each interview, roughly 15 mins was allocated to behavioural questions around OLP. There are lots of resources online which really helped me tackle it. They seem to ask the question in each interview for consistency.
For technical, you get around 30 mins to solve it. I got two questions on designing data structure which required knowledge of hashmap, priority queue, stack, linked list and of course, sound knolwedge of OOPs. I think OOPs were very important since they cared about scalability and maintainability of the data structure you create.
The third one was LC medium question which I could solve in a brute-force way but only could tell them the psudo-code of optimal solution with the interviewer's help.
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.
