I applied online. I interviewed at Optiver (Chicago, IL) in Feb 2025
Interview
Received a 65 min OA with mental math, statistics, and coding sections as well as a 2 hour long brain games assessment. Was just contacted about completing a 20 min behavioral phone interview with HR.
Interview questions [1]
Question 1
If you have a deck of 52 playing cards, 13 are hearts and 12 are face cards, with 3 set of each suit, what is P(AUB) where A = hearts and B = face card?
Overall, it was a great experience. had an engaging conversation with them and the entire process felt pretty smooth and structured. They were professional and welcoming and made it easy for me to share my background and interests.
