Interview Process
The interview consisted of multiple-choice questions and coding problems. Candidates were asked to solve theoretical questions related to finance, statistics, and programming.
Technical Questions
- Shuffle an ordinary deck of 52 cards containing 4 Aces. Turn up cards from the top until an Ace appears. Which of the following is NOT right?
- In an 8-player poker game, each player is dealt 2 cards from a regular 52-card deck. Which of the following statements is TRUE?
- There are 2025 fair coins in a bag, with 47 of them having HEAD on both sides. You randomly pick 1 from the bag and toss it 4 times, all outcomes are HEAD. What is the probability that this coin has both sides HEAD?
- Regarding a linear regression, suppose you deleted several observations that had small residual values. If you re-estimate the regression using the reduced sample, what would likely happen?
- Which of the following statements regarding Markov Processes is incorrect?
- “Conditional heteroskedasticity will result in consistent coefficient estimates, but both the t-statistics and F-statistics will be biased, resulting in false inference.” Is this statement CORRECT?
- Which statement about Ridge Regression is NOT correct?
- You are holding a portfolio with n assets (n > 5), all at the same risk level. How many Y should you hold to minimize your portfolio risk given the correlations and variances of assets X, Y, Z?
- You are estimating the probability theta that a coin lands heads using Maximum Likelihood Estimation (MLE) and Maximum A Posteriori Estimation (MAP). Which of the following best describes the MLE and MAP estimates?
- A stock price follows Geometric Brownian Motion, with an average volatility on log return to be 30% for the next year. Which of the following statements is NOT correct?
Tips & Insights
Candidates should be prepared to discuss both theoretical concepts and practical applications in finance and statistics. Understanding the implications of different estimation techniques, as well as portfolio management strategies, is crucial.
