I applied online. The process took 3 days. I interviewed at Optiver (Chicago, IL) in Oct 2020
Interview
They gave me a custom Hackrrank problem where I have to write a tree search algorithm that detected cycles, ill-formed data, and illegal splits. They scheduled me an interview without any technical questions.
online interview was difficult. There were three parts: coding, mc questions, and number theory questions. can't prepare for the second and third, and first was a hard + medium lc.
