J'ai postulé en ligne. Le processus a pris plus de 2 mois. J'ai passé un entretien chez Citadel (New York, NY) en oct. 2023
Entretien
The interview process was smooth, with the first round being phone interview, two probability questions, questions were harder than Green book questions. It would be helpful to review distribution and probability.
Unexpected question, mainly focus on intuition and quick thinking. Need to explain the whole thinking process. Make quick decision and estimation when there is no enough information, brain teaser type of question

Interview was great, and was ML and Stats based mostly. He went over probability question, and ML Architecture Question, then Options and stuff. It was good experience and I liked it.
5 rounds, hard math and probability questions, some competition and olympiad style, some standard dice and conditional probability questions. Seemed fair and challenging, appropriate for the role. I thought the length of the process was quite excessive and I assume that is due to their enormous applicant volume
