I applied online. I interviewed at Optiver (Chicago, IL)
Interview
5 rounds. OA - Gambling - Math - HR - Data Science. Unsure if process will be different. Generally starts with introduction then gets directly into the problem. Small hints are given if stuck.
Other Quant Research Intern interview reviews for Optiver
First two rounds consisted of playing typical EV games with some capital (dice questions, cards, market making). Followed by take home assignment involving data science/ML. Then meet with researchers at optiver to discuss work.
Interview questions [1]
Question 1
Given 3 minutes, what would you buy here and how much would you allocate?
Friendly interviewer, intense online assessment. Online assessment covered probability questions on mostly expected values, and stochastic probability. There is a finite deadline to complete it. This is then continued with a behavioural interview if you pass, that can be booked online.
