Ho presentato la mia candidatura tramite l'università. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Citadel Securities (Chicago, IL) nel mese di ott 2020
Colloquio
Contacted via campus recruiter for my university. One initial phone round with 2 quantitative questions, one final round with 4 separate interviews ranging from IMO-style to programmatic. Had a good experience overall, some of the interviewers seemed a bit unhappy to be a part of the process, however.

Colloquio
Pretty interesting with a few brainteasers (dealing with unknown information and get a rough estimate about them ) and a probability question. Both are pretty easy but I messed them up.

Colloquio
Had a referral but had a ~30 min OA + 2 rounds of 45 min of mainly technical + in person super day (that I didn't reach). Was pretty standard for a quant trading interview. They were very responsive.
