I applied online. I interviewed at Optiver in Oct 2023
Interview
OA asking quick mental math and a basic coding problem in the language of your choice. The mental math was relatively fast paced but nothing more than 2 digit multiplication and fraction manipulation.
Interview questions [1]
Question 1
If you arrange the numbers 1-9 on a 3x3 grid randomly, what is the probability that all rows and columns add up to an odd number?
Took and online test. It had multiple sections but once you failed one section you failed the exam. Made it to the logical reasoning section and got tripped up on some pattern recognition questions. I would definitely spend some time reviewing the online material for the exam
