Colloquio
One screening interview and then 3 back to back technical interviews. The screening was done by a seemingly fresh developer who didn't understand some of my answers, so i had to give him another basic algorithm. The technical interviews discussed my resume (thank goodness somebody cares about prior experience), had a graph problem that is solved by BFS, and finally there was a question that was much more complicated than the person asking it realized. Overall, I was frustrated by the level of preparedness of my interviewers.

Domanda 1
A question about finding anomalies in a stream of data. I couldn't code an answer because I could think of so many ways the data stream can gradually deviate from its expected distribution. The interviewer ended up giving me the algorithm and I coded it then showed him how it is not a general solution. During my though process I asked for clarification question that he wasn't prepared to answer.
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
