I applied through a recruiter. The process took 2 days. I interviewed at Optiver (Amsterdam) in Feb 2016
Interview
First round was the mental math test where you have to answer as many questions as possible within the time limit. If you reach the threshold in time, you go to the next round. If you don't, you're out. Simple as that. While they used to have the test on a computer, they switched back to paper which was unexpected. You had to solve the question and go to another sheet of paper to tick the correct box. This all took longer than I anticipated.
The following proces:
1st round were games, including mental math, memory games
2nd round was hr interview, asking questions about motivation
3rd round: technical interview
4th round: technical interview
5th round: at office
I only got past the online assessment and got to the first round which was a HR interview. The online assessment involves 2 tests, probability questions and one with some form of games which test your reaction time, your thinking etc. it was quite fun to do
Interview questions [1]
Question 1
One thing they asked was my experience/what I did for trading. Unfortunately, I had no experience within trading.
80x8 Test : mental math exercise where I had to solve 80 short arithmetic problems in 8 minutes without using a calculator or paper. The questions are usually simple in structure—typically involving addition, subtraction, multiplication, or division of small numbers
