Envié una solicitud electrónica. El proceso duró 2 meses. Acudí a una entrevista en Citadel (Londres, Inglaterra) en ago 2024
Entrevista
I interviewed with several Hedge funds, and the process with Citadel is by far the worst of all of them. A very compact one with unclear steps. I did 4 rounds with them and they promised I will get a response very shortly, and then a complete ghosting, even though I tried to understand what is the issue or at least get a feedback even though I thought at least 3 rounds of the four went perfect.
- Questions on Linear Algebra and Coding
- Discussion of a problem at the intersection of optimization and classical machine learning
- No behavioural questions or anything about my personality or work experience, the interview was purely technical
Preguntas de entrevista [1]
Pregunta 1

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.
