Expected value of rolling an -sided die where you can choose to reroll once. 150 Most Frequently Asked Questions On Quant Interviews
What is the curse of dimensionality, and how does it degrade distance-based algorithms like KNN?
State Ito’s Lemma and walk through a simple derivation. Why is it so important in finance? Q121 - Q122: Write down and interpret a simple Geometric Brownian Motion (GBM) SDE. Q123 - Q124: What is the difference between a process with drift and a true martingale? Can a process with a drift be a martingale? Q125 - Q126: What does Girsanov’s theorem do? Why is a change of measure needed for derivatives pricing? : Derive the MLE estimator for the parameter
: State the Central Limit Theorem. What are its underlying assumptions, and when does it break down in financial modeling? Uniform Distribution Min/Max : If
These questions assess your knowledge of financial products and the models used to price them. Candidates for quant roles in derivatives trading or risk management will face numerous questions in this category. How do you calculate it given a transition
: Logic and ingenuity puzzles frequently used to test candidate intuition. Google Books Where to Find the Guide
16. Normal Distribution: If $X \sim N(0,1)$, what is $E[|X|]$? 17. Uniform Distribution: Two random variables $X$ and $Y$ are uniformly distributed on $[0,1]$. What is the probability that the distance between them is greater than 0.5? 18. Exponential Distribution: What is the memoryless property, and how does it apply to radioactive decay modeling? 19. Gaussian Integrals: Calculate the integral $\int_-\infty^\infty x^2 e^-x^2 dx$. 20. PDF/CDF: Given the PDF $f(x) = 2x$ for $x \in [0,1]$, calculate the median and the mean.
