References checked. How long to wait for a potential job offer?

References were completed three business days ago. Got a call for an interview nearly three weeks ago, a day after I applied. Panel interview went smoothly, no technical questions, just behavioral/personality questions. References were requested the same day. I was excited!

Then, the waiting game... I took the matter to my own hands and did some investigating (actually called the reference check company and they told me they accidentally had an incorrect email address for a reference and the other one was on vacation). Finally, I scrambled to get all of my references in place.

It's been officially three business days since my references were contacted/paperwork completed. I've always got my nursing jobs the same day during the interview so this process is new to me - how long do you wait before contacting the recruiters or should I wait until the end of the week? Worried that I missed the window of opportunity as there was a massive hire and they were hiring as they go, not from a pool of candidates.

Thank you!
