First interview with questions on SQL and Python, as well as standard mathematics questions (CLT, Black-Scholes, some puzzles). Nothing spectacular, but you need to be prepared. On the mathematics side, the questions were tricky, with some common problems to solve, but it’s still difficult to tackle an unfamiliar problem under pressure in front of people you’ve just met.

Take home exam on data analysis and statistical inference, and then two rounds technical interviews, mostly probability and classical statistics and machine learning. Some simple algorithm questions done verbally too.
