Citadel Securities Business Intelligence Analyst interview experience

I went through a few case-study rounds, and the experience stayed consistent in how it was run.

The final round blended multiple formats: there were coding exercises, a case element, and also behavior questions. What surprised me a little was how quickly the follow-ups happened after the results came in—communication felt fast and responsive rather than slow and vague. Overall it felt like an interview loop designed to run efficiently end-to-end, even though it still asked a lot in the final step.
