J'ai postulé via un recruteur. J'ai passé un entretien chez Citadel (Chicago, IL) en sept. 2017
Entretien
Two rounds phone interviews. Ask about my research and intern experience. Then talk about programming in C++. Another question about basics in linear regression/LASSO/ridge regression. Expect to have online coding questions but didn't get asked.
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.
