I submitted my application and received an OA invite immediately. The test was a lot of timed math and basic probability questions (like most OAs for this type of role). There was no coding portion though, which was what I prepared for the most.

Submitted application and received invitation to online assessment immediately. Needs to be completed within a week. Had 3 programming questions followed by probability, number logic, and Zap N mini-games. I consider myself to have done it reasonably well, but haven't heard back since and thus can safely assume rejected.
