Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Citadel (New York, NY) nel mese di gen 2017
Colloquio
I interviewed in January 2017. The first 15 minutes were questions about my resume and the following 30 mins were questions on statistics, probability and algorithms. The interviewer was nice. I think I did well on all problems except the linear regression questions.

Start with my own self-introduction and the interviewer's self-introduction first for five minutes, then a couple of technical questions for like thirty minutes, and in the end, questions for the interviewers about the company.
I received the interview a few weeks after applying online. During the interview i was asked by the interviewer about my past experience and also some other related technical questions.
