Application
I interviewed at Optiver (Amsterdam)
Interview
I have been able to do only the first part... neamely the part in which they ask to compute multiplication, division, addition, subtraction etcc. , it was though, But I think that if you prepare very well there are chances to go to the next step
Interview
First there was an online assessment to test mathematical aptitude. After this, there is a phone screening. Then there were technical questions (stats/probability and game theory) over the phone and HR questions over zoom.
