Citadel recruits heavily from top universities and competes in the same talent market as elite quant and trading firms.

/ 100
Citadel provides high-quality early-career entry through structured internships and named programs across investing, quant, and engineering, but access is highly selective and not designed for mass graduate hiring. Citadel is clearer than many finance employers on interview format in key tracks and offers strong on-the-job learning, yet pay transparency and published early-career outcomes are limited.
