Candidatei-me online. Fui entrevistado pela Amazon em jun. de 2013
Entrevista
I applied about one month ago. Then after two weeks, I got an email from recruiter in Amazon asking me to do an online assessment in 6 days. I've done it last night. The questions are relatively simple, people who have gone through data structures can solve it without too much thinking. It was 3 questions in up to 90 minutes. The hard part is for each question, I have to write down description of approach, assumptions, which data structures used and why, analysis on complexity, and code comments. It took me more than 10 minutes to get these documents done (one can easily tell I am not native speaker btw:) )
There was another session for behavior test after finished 3 questions. Things about whether you think you are creative, or what will you do if you find a minor bug near deadline. All self-selection questions.
I just finished the first-round. Long before I get a position. Since I have to select whether get offer or not. Better to select a yes for good luck :) Wondering if I can update later

Writing documentation for 3 test questions took me a big way too long time.
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.

Pergunta 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.

Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.

Pergunta 1
The first question is LeetCode style algorithms question, and the second question gives a full stack repo (choice of Java, NodeJS, or Django) and asks to solve a backend issue which is causing a bug in the frontend. Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
