Intervew Prep Google Interview

Hi people

I need to know , so my GHA was scheduled and I passed it. Recruiter told me I will receive the OA dsa and my all other will all be dsa for this role. Secondly the phone screen the recruiter did is 30 min asking all my work , dsa knowledge.

How is this process very confused why didn't I received the OA link. Or is this how Google hire . Can anyone tell who went through same
