I applied online. The process took 2 weeks. I interviewed at Optiver (Chicago, IL) in Sept 2022
Interview
I received the Zyvo assessement two weeks after submitting my application. 4/5 sections are counted.
I didn't meet the threshold of the 4th section, which is the probability one. Make sure to take breaks between sections and I think the second one is the most stressful one cause you have to remain focus and quickly adapting to the new challenge for an hour.
Interview questions [1]
Question 1
Mental Math, Sequence, Probability. The second section is a numerical test and the 5th one is a personality test.
