Submitted CV and cover letter online. No online assessment, first a Zoom interview. In total it was 45 minutes long, and the interviewer asked mainly maths and programming questions. Some long problems, some short recall-based questions. It was a bit uncomfortable, because the level of maths and programming was low, (like high school or early undergraduate) but if you are not actively revising those topics (hard if you already have a full time degree to be focusing on…) you might have just forgotten how to do some of those things.
Interview questions [1]
Question 1
One maths calculus question using moments of expectation. One probability question. One algorithm/data structures question including linked lists. One combinatorics question involving cards that are arranged in a certain size grid.
I interviewed at Citadel Securities (London, England)
Interview
Dynamic programming question with some expectation computation. It also involved cv based questions with emphasis on technical topics on the projects I did. It was okay on difficulty, I could have passed it.
I interviewed at Citadel Securities (New York, NY)
Interview
resume submit, then 45 min call with interviewer. interview was really nice, calm, and provided guided hints. first 30 minutes were technical on math and coding and next 15 min were behaviorual.

Interview
Long discussion about stats concepts like hypo testing, regression etc. Multiple standard brainteasers, can be found online. Interviewers are helpful, it is a genuine discussion rather than a one way solving interview
