Citadel Quant Research Intern Interview Experience
The Black-Scholes formula stands as one of the most significant achievements in quantitative finance, providing a theoretical framework for pricing European options. Aspiring quant researchers, especially those interviewing at top-tier firms like Citadel, are frequently tested on their understanding of this formula—not just its application, but its derivation and underlying assumptions.
The Black-Scholes formula, developed by Fischer Black, Myron Scholes, and Robert Merton in the early 1970s, revolutionized the field of financial engineering. It provides an analytic solution for pricing European-style options—contracts that can only be exercised at expiration. The formula is a direct consequence of modeling the evolution of asset prices using stochastic calculus and constructing a riskless hedged portfolio.
Understanding the Black-Scholes formula is not only crucial for passing quant interviews at elite firms like Citadel, but also foundational for anyone pursuing a career in quantitative finance or derivatives trading.
