Me postulé a través de un reclutador. El proceso tomó 3 semanas. Acudí a una entrevista en Citadel Securities (New York, NY) en sep 2025
Entrevista
I was given a hacker rank exam. Difficult questions definitely LC hard. Trees, Double heaps, and stack tracking bar widths were all involved. I’d say prep LC hards you haven’t seen and do your best.
