Answers to the most common questions asked in quantitative finance interviews

A practical guide to quantitative finance interviews

1. What is the efficient frontier?

The efficient frontier is the set of portfolios that offer the highest expected return for a given level of risk. Portfolios that lie on the efficient frontier are said to be “efficient” because they provide the highest possible return for their level of risk.

2. What is Sharpe ratio?

Sharpe ratio is a measure of risk-adjusted return, which compares the expected return of an investment to its volatility. A higher Sharpe ratio indicates a better risk-adjusted return.

3. What is value at risk (VaR)?

Value at risk (VaR) is a measure of the maximum loss that an investment could sustain over a given time period, given a certain level of confidence.

4. What is the capital asset pricing model (CAPM)?

The capital asset pricing model (CAPM) is a model that describes the relationship between risk and expected return. The model states that the expected return of an investment is equal to the risk-free rate plus a risk premium.

5. What is beta?

Beta is a measure of an investment’s volatility in relation to the overall market. A high beta indicates that an investment is more volatile than the market, while a low beta indicates that it is less volatile.

6. What is the efficient market hypothesis (EMH)?

The efficient market hypothesis (EMH) is the theory that financial markets are efficient and that prices reflect all available information. The EMH states that it is impossible to beat the market because all relevant information is already factored into prices.

7. What is a random walk?

A random walk is a sequence of steps in which each step is taken at random, with no regard for the previous step. A random walk can be used to model how prices change over time.

8. What is stationarity?

Stationarity is a statistical property that indicates that a time series does not have a systematic trend over time. A stationary time series is one that is constant in mean and variance over time.

9. What is autocorrelation?

Autocorrelation is the degree of correlation between a time series and itself. A high degree of autocorrelation indicates that the series is highly correlated with itself, while a low degree of autocorrelation indicates that the series is not as strongly correlated with itself.

10. What is a z-score?

A z-score is a measure of how many standard deviations an observation is from the mean. A high z-score indicates that an observation is far from the mean, while a low z-score indicates that it is close to the mean.

What do recruiters look for in candidates for quantitative finance positions?

Some recruiters may primarily focus on a candidate’s technical skills when considering them for a quantitative finance role. However, other important factors that recruiters may take into account include a candidate’s ability to think critically and solve complex problems, as well as their ability to effectively communicate their findings. Candidates who are able to demonstrate both their technical abilities and soft skills will likely be the most competitive for these roles.
