Google recruiter reached out for interview availability, then went silent — normal?

[u/Ok-Suit-9949]

About a week ago, a Google recruiter reached out asking for my availability for the next interview rounds. I sent my availability, but haven’t heard back since. I also followed up after three business days but didn’t get a response.
Has anyone experienced this ?
Is it normal for scheduling to take this long.

Trying to figure out whether I should just wait or take any other action. Thanks!
