Citadel Data Science interview questions

Starts with an overview of your resume and a review of any experience you have working with data and the impact it has. Then you have some case studies on different datasets and how you use them to derive investment relevant insights.

A few rounds with hiring manager and team members. Then 3 hour technical assessment working with data in Jupyter environment and answering questions. The final interview was supposed to be meeting with the COO but they ended up giving several additional interviews after that which were not in the original process laid out. It ended up going on for several months.
