The technical round kicked off with a query about choosing models for trading tasks, which felt straightforward. Then I tackled a problem analyzing correlations and generating Gaussians. The interesting part was recognizing the prompt instantly — it was the same question I had worked through on prachub.com during my prep. Overall, the interviews moved quickly, with a positive vibe throughout, and I felt confident enough to accept the offer when it came through.
I applied online. The process took 4 weeks. I interviewed at Citadel in Jan 2025
