I applied through college or university. The process took 3 weeks. I interviewed at Optiver (Amsterdam)
Interview
I interviewed with them in 2021 and stuff could've changed by then.
The assesments were infamous Optiver 80 in 8 minutes, followed by a sequences test, then their own GUI test which consisted of games, some similar to Human Benchmark.
The second round of OAs were a numerical and then a verbal aptitude test.
I had a group discussion after that.
Finally there was 1 HR and then 1 Technical interview.
Interview questions [1]
Question 1
The technical interview was rather straightforward, with some puzzles that were easy and some recursive probability questions.
The HR interview felt more like a casual conversation as compared to an interview.
a very typical intern interview, just ask u some normal question about ur background and why trading why the company
only general behaviour question, nothing about math or tech for the first round interview
There were many different mini games that did not immediately appear relevant to trading. The games during the interview appeared to measure confidence, technical skill, and how risk averse the candidate was.

Question 1
You and N other players are each dealt a number and bet on the average taking turns and going around many times. What is your strategy? How does it change if everyone knows the distributions the numbers were sampled from?
