CB Scheduling timeline

I had a screener on Tuesday and it went great on Wednesday the firm reached back out to invite me to a CB interview. I submitted a form with my available times right away and now it’s Friday and I still haven’t heard back. It’s my first CB so I’m unsure of how this works and my screener was scheduled within an hour of me submitting the form with my availability. Is this normal? Should I reach out next Wednesday if I don’t hear back? I just really love the firm and anxiety is spiking
