I applied through a recruiter. The process took 2 weeks. I interviewed at UBS (Londres, Inglaterra) in Mar 2024
Interview
Onsite interview in London. Three technical interviews with questions on undergraduate level math, machine learning and statistics. The questions were fair, though some brain teasers from probability theory were tricky. Then two rounds with management and HR.
Interview questions [1]
Question 1
There wasnt a single question that was most important. One of the technical questions were to decide whether a certain convex functions inequality was true
Good process, fair questions, standard quant type questions on probability. Interviewer was very fair and friendly, and there was no desire to ask extraordinarily tricky questions. Overall, very streamlined and efficient process.
I applied online. The process took 2 weeks. I interviewed at UBS (Varsovia, Mazovia) in Aug 2024
Interview
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.
