I applied online. The process took 2 weeks. I interviewed at Optiver (Chicago, IL) in Sept 2016
Interview
The interview began with a short online mental math test. Upon passing, there is a telephone behavioral interview with an HR person, mostly discussing your choice of college, major, etc. Next comes a longer, more difficult online math test covering probability and patter recognition. After this there is a second phone interview, where they ask consulting-style estimation questions, and math and probability questions. Finally there is an in-person interview in Chicago.

I applied online. The process took 2 weeks. I interviewed at Optiver (Sydney) in Mar 2023
Interview
Had to first complete and pass 5 online quizzes, mostly relating to math (e.g. mental math and pattern recognition) Then the final round interview consists of 3 back-to-back zoom interviews. Progression to subsequent round depends upon performance in previous round. First and second interviews were 1 hour long each and were simulated games that emulated the stock market. After the second interview I got a call that I will not be progressing to the last interview.
I applied through university. I interviewed at Optiver
Interview
It was very fast paced. And they expect you to be quick with mental math and good at grasping information. The questions were very interesting and real-life. The communication was also well done. There were 2 days of assesment, then a GD, then a personal interview with a trader for 45 minutes, then the final on campus day.
