I applied through a recruiter. The process took 4 weeks. I interviewed at Amazon in Jun 2022
Interview
Stage 1. Call with Recruiter (one of the best, and probably the only good part in the whole process)
Stage 2. Technical OA, medium/easy LC Qs on linked list and string array manipulation
Stage 3. Virtual onsite (4 rounds)
-- 1 interviewer who is not in the interviewing team. (Amazon LP and one easy sorting hits Q)
-- System Design on Messenger (interviewer checked out after screen share did not work in Amazon chime. I used a notepad and pen. Later found out that browser needs to allow screen recording , which was not allowed by default in my new system).
-- Behavioral round with manager on Amazon LP Qs and one long Q with a simple solution on OOP. The interviewer just copy pasted it and told me to read it and solve when only 15mins was left.
-- one medium LC question (I used backtracking, interviewer was not impressed because I did not use Trie)
2/4 interviewers were one of the worst that I have ever been to because one was disrespectful, said "nice story" to my project experience which I was passionate about and had put a lot of hard work on. The other one had terrible audibility because of an accent like a bullet train and low mic quality, I had to ask several times to repeat, also dismissive behavior about all the working solutions I provided (DFS, BFS, backtracking).
Giving this a neutral experience still because it seems to be a team specific behavior, and I think I could have still done better. Use the interview window to make sure you don't land in a toxic team.

Question 1
The usual LP Qs. Tell me a complex problem you solved with a simple solution?
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.
