J'ai postulé via une autre source. J'ai passé un entretien chez Virtu Financial (New York, NY)
Entretien
The process felt pretty progressive overall. Early rounds were more about fundamentals — stats, ML, probability, coding, linear algebra, etc. Later rounds became much more discussion-based and open-ended, closer to research conversations than standard interviews. A lot of emphasis on reasoning under uncertainty, communicating ideas clearly, and staying calm when exploring unfamiliar problems. Less about memorizing formulas, more about how you think.

Question 1
One question I remember was discussing when maximum likelihood estimation can fail or become unstable in high-dimensional settings.
Tough but people are easy to talk to, friendly convos with some technical and behavioral mix. Depending on who you met but definitely come prepared. if they like you and you check all the boxes it should be all good, good luck
HR is very nice. Just basic behavioral questions and brain teasers. Talk about personal background to see if there's a match. Move to the second to interview with hiring manager next.
