I applied through a recruiter. I interviewed at Citadel
Interview
I had three technical rounds (Math, CS, Math) followed by a discussion with a manager which was a mix of behavioral and technical. The technical questions were interesting and of similar difficulty to questions asked by comparable firms. The one exception was that I had a question involving martingales. I have a pure math background so this may have been specifically targeting that background.
The chat with the manager turned me off from Citadel, and I ended up withdrawing as I had an offer elsewhere. He was a new manager who came off as closed-minded and having a massive ego. For some reason he also went on multiple rants about how brilliant Kenneth Griffin is...

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.
