Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto 4 settimane. Ho sostenuto un colloquio presso Optiver (Chicago, IL) nel mese di dic 2015
Colloquio
First we had a simple phone interview. Just talked about interests and stuff and why I want to work at Optiver. Next was 3 questions on hacker rank. Test was not horribly difficult, just make sure to be good with what every language you use and know how to use standard libraries to make your life easier. Finally is an onsite with 4 rounds. Positive experience in all of it and definitely was a good indicator of skill. Definitely was difficult, but nothing unmanageable.
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.
