J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Citadel Securities (Chicago, IL) en nov. 2025
Entretien
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.

Entretien
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.

Question 1
They asked a weird betting game with unknown balls in a bag and unknown draws.
Overall, they were responsive and happy to interview. My interviewer was really nice and the problems were fun to tackle. Although I was rejected it was a good experience overall.
