I applied through college or university.
There is an online OA test at first. If you pass the OA, there will be an HR phone call interview, 3 round tech interview, and a final behavior interview.
The following metrics were computed from 1 interview experience for the Optiver Software Development Engineer Intern role.

Candidates reported having very good feelings for Optiver's Software Development Engineer Intern interview process.
