To add anecdata to your post here, in the height of the hiring craze last year, I accepted an "above-market" (from my perspective) offer from a company called Provi. They took less than a week from initial recruiter call to offer.

Fast forward to this past February, and I'm being let go for "performance reasons", but it's a lot clearer in retrospect that I should've been failed out of their interview process if it was any good, and that seeking to hire someone within a week is now sort of a yellow flag for me.

I want to move fast, but I also want my counter-party to do proper due diligence.
