I applied through an employee referral. The process took 2 months. I interviewed at Citadel (New York, NY) in Jan 2024
Interview
Multiple rounds with behavioral and technical components, a technical project focused on building predictive models in python, and a final round that combines elements of prior rounds with conversations across different levels
Interview questions [1]
Question 1
How would you run a Monte Carlo simulation in Python for predicting the probability of getting 4/6 coins as heads without using for loops?
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.
