First there was a screening, then online tests on math (lots of problems covering different areas) and programming (3 easy problems about data parsing and filling in gaps). After that, there were 3 technical interviews focusing on math, programming, and DS/finance. These usually started with a few simple warm-up questions followed by 2 harder problems to check how deep your knowledge goes. Then, I had interviews with the teams where we talked about my experience and scientific work, followed by questions specific to the team I was applying to, and I had to come up with hypotheses about the data. I got rejected.
Confirmed questions3 questions
- Did you have knowledge of mathematical induction?
- The team interview included questions from the Green Book.
- The questions from other stages were unique but fairly straightforward

First, there was an HR screening, then 2 online tests (maths and programming) with a 3+2 hour limit. These tests cover university-level maths and three quite simple coding tasks, but be warned, the tests were awful: they had wrong assertions and pretty strange score evaluation, so you might fail even with correct code. After that, there were 3 interviews (maths, coding, and data science). Then, I had another 3 interviews but didn't succeed in those.

The interview process wasn't fully clear as I only got as far as the initial Hackerrank assessment and didn't proceed further. The questions were quite confusing and seemed unusually complex, suggesting that standard preparation might not be sufficient due to the need to decipher their intricate questions.

Quoted word for word from WorldQuant interview reports.
“Given five points located inside an equilateral triangle with sides of length 1, show that there must be at least two points that are closer than 1/2 to each other.”

Read reports →“A ray travels inside a unit cube with mirrored faces, starting from one vertex, reflecting off four faces without hitting edges or vertices, and ending at the opposite vertex. What is the shortest possible distance the ray travels, approximated to 4 decimal places?”
Read reports →“In a random seating arrangement of nine boys and seven girls around a circular table with 16 seats, what is the expected number of adjacent girl-boy pairs?”
Read reports →“Given 10 islands in a line with two bridges connecting each pair of consecutive islands, where one bridge is functional and the other is broken (leading back to the start if used), what is the expected number of times you cross a functional bridge when starting from the first island and reaching the last one?”
Read report →“What's the least number of operations to make all numbers in an array the same, given you can only add or subtract 1 from any number?”
Read report →“Three riflemen, A, B, and C, with a 0.5 probability of hitting the target, take turns shooting. The first to hit wins $2002. A shoots first, then B, then C, and the cycle repeats. What is rifleman A's expected winnings?”
Read report →“In a basket with 4 green and 50 red apples, apples are removed one at a time without replacement until all green apples are gone. What is the expected number of apples remaining in the basket?”
Read report →“Given a function F that calculates the product of matrices and takes MxNxK nanoseconds for an MxN matrix and an NxK matrix, calculate the minimum time in nanoseconds to find the product of five matrices A, B, C, D, and E with dimensions 2x100, 100x10, 10x10, 10x100, and 100x2 respectively, using only function F.”
