Ho presentato la mia candidatura online. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Optiver
Colloquio
After I submitted my CV and a motivational letter I received a url for a Hackerrank test. The test was 3h long with the last task being by far the most demanding. There were multiple choice theory questions and tasks that required coding.
Domande di colloquio [1]
Domanda 1
Read an encoded tree (composed of pairs of nodes), verify the correctness of the input and among others, search for cycles.
A bit anxiety inducing, there were two developers observing and asking questions. Real-time problem solving required, conducted on Hacker Rank virtually, video and mic enabled - quite nervewracking to say the least
I had one round, which was an online HackerRank test. I wasn’t able to pass all the test cases, and as a result, I did not progress to the next stage of the process.

Colloquio
A lot of interviews. Started off with a call, then some online tests. Then a technical interview. Then a live coding interview along with a architecture interview. Last step would have been final day interview but I did not get that far.
