Data Engineer Interview

How would you remove an element from a linked list using an iterator?

Quantitative Analyst Interview

Given an array of dates in string format (e.g., '20050301'), write a function that returns the year and quarter for each date (e.g., '20050301' => '2005Q1').

Quantitative Analyst Interview

A college maintains department information in one table and student information in another table. Write a SQL query to display the number of students by major in descending order.

Quantitative Analyst Interview

How do the estimated beta coefficients and t-statistics change in Ordinary Least Squares (OLS) regression if each sample in the dataset is duplicated?

Quantitative Analyst Interview

What is the event loop?

Software Engineer Interview

Software Engineer Interview

Given a table containing names and ages with some duplicate entries, how would you return all duplicate rows using SQL?

Data Scientist Interview

How much should you be willing to pay to play the following game? You start with $1. You flip a fair coin. If it lands on heads, you double your winnings and flip again. If it lands on tails, the game is over and you collect the money you've won. You continue playing until you land on tails.

Data Scientist Interview

How would you create a predictive model of y given x, where x is a continuous variable between 0 and 10 and is linear on the integers? Follow-up: If you model this using 10 separate regressions, what would be the effect? If you average the regressions at the integers, would these be biased estimates?

Data Scientist Interview

Can a tuple or a list be used as a key in a dictionary?

Data Scientist Interview

Explain bias and variance. Which models tend to have higher bias versus higher variance?

Data Scientist Interview

What happens to the F-statistic and t-statistic if you replicate the data in a dataset?

Data Scientist Interview

How would you calculate a covariance matrix when the underlying data is too large to fit into memory?

Quantitative Researcher Interview

What is the time and space complexity of finding the most profitable buy and sell dates given stock price data, if you are allowed only one buying and one selling transaction?

Quantitative Researcher Interview

In the secretary problem, given n independent and identically distributed random variables drawn from a uniform distribution, what is the optimal strategy to maximize the expected return when you can only select the first variable that meets your criteria? Describe the method for finding this strategy.

Quantitative Researcher Interview

You roll a 100-sided die and bet on a number; if you guess correctly, you win an amount equal to the number you bet on. What is your optimal betting strategy?

Quantitative Researcher Interview

What is the difference between deep Q-learning and Q-learning?

Quantitative Researcher Interview

In a dice game, you roll a fair six-sided die once. After seeing the result, you may choose to either accept the result or roll the die a second time. What is the expected value of the result if you play optimally?
