I applied through other source. The process took 6 days. I interviewed at Citadel (London, England) in Mar 2023
Interview
Hard questions about non linear optimisation. I think I answered everything well but didn't get a second round. Practice makes perfect so make sure you read up on interview prep
Very good and helpful, enjoyed how they had a technical aspect as well. The interview was nice and very nice and kinda nice. Extremely nice broski, lowkenuinely a nice experience broskini.
First round discussing work experience and some hypothetical research questions and how I would approach the problems. Highly conversational and chatty. Interviewer was nice and friendly and offered his insight along the way.
It started with an automated coding screen in a language of your choice, which I unfortunately did not get past. I chose Python for the screen, the questions were pretty standard I just wasn't prepared.
