Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto 3 mesi. Ho sostenuto un colloquio presso Amazon nel mese di mag 2014
Colloquio
I am from Madrid, Spain and the position was for Seattle, WA.
I contacted a recruiter via email. The whole process took 3 months.
They sent me a link to do an online test, through interviewzen. It consisted in two parts:
- Java coding. It was about binary trees and recursion.
- OOP question. It was about inheritance and polymorphism.
I passed the test so they scheduled a technical phone interview with an engineer few weeks later. This was the script:
1) Questions:
- First question apart of “Is this a good moment?”: Why do you want to work here? => You better be ready for this.
- Which projects of your career are you proud of?
- Which languages are you familiar with?
- Why? => I didn’t expect this question.
- Are you familiar with trees?
- Really? What is a tree?
2) Technical part, coding.
- We used collabedit.
- It was about binary trees and recursion again.
- It’s not worth it to put the question itself, just be ready to be asked about data structures, recursion and efficiency in terms of Big O.
3) Interviewing the interviewer.
- You should have 3-5 questions for them.
It took one hour and one minute.
They sent an email 3 days later saying "we have decided to move forward with the search process in order to target the candidate…”.
Looking backwards I don’t think it was difficult. I wasn’t ready enough.
They were very kind with me all the time and I learnt a lot during the process.
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.

Domanda 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.

Colloquio
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.

Domanda 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
