Candidatei-me online. O processo levou 2 meses. Fui entrevistado pela Amazon (Toronto, ON) em mai. de 2021
Entrevista
I initially applied online through Amazon Jobs page and received a reply to complete the Online Assessments in March. I completed 3 rounds of OAs over a span of 2 weeks and received the invitation to the Final Interview which I had it scheduled for May.
The final virtual on-site interview consisted of 3 sessions, each being 45 minutes long. For each session, around 10-15 minutes are spent first with behavioural type questions on variuos Leadership Principles, and the rest are spent for Data Structure and Algorithms type questions.
The DS&A questions were usually started off with a very simple question, and when I got it correctly, they built up from the question with additional constraints/performance improvements.
It took them 5 business days to get back to me with the result.

Pergunta 1
Q: Did you make any mistakes and what did you learn from it?
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
