I applied online. The process took 2 weeks. I interviewed at Optiver (Chicago, IL) in Oct 2025
Interview
First round OA- 3 parts including coding and mind math test
Second round phone behavioural - 15 min calls asking past experience and they gave me a lot of time to asking questions
I got rejected at the second round.
Other Software Engineer(Internship) Interview Reviews for Optiver
OA; quite long, 3 tests
Behavioral interview: just a short talk with HR, motivation,…
Technical Interview 1: fundamental CS, nothing more
Technical Interview 2: system design, very vague but just go with the flow
Technical Interview 3: live coding, still leetcode but optiver style is a very descriptive problem, but the main thing could be boiled down into only few lines
Difficult OA. Design question. Included min/max heap with lazy deletion + fib number sequencing + hashmaps all in one question. Easy techincal in comparison. Just don't stop typing during the OA and make sure to read everything carefully.
