I applied through college or university. The process took 4 weeks. I interviewed at Citadel (New York, NY) in Oct 2017
Interview
Talk to HR first to decide which team you can apply, then with every members for technical tests. Usually they arrange one round each week. And it could be two if you say it is urgent.
Interview questions [1]
Question 1
How do you think the location of the company? Is it an advantage or disadvantage for you?
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.
