Quick and efficient. From the screening to the offer, the whole thing took less than a week. They expected a quick turnaround on accepting or declining the offer as well, it was a 24-48 hour window for a big decision.
Quick, efficient, and respectful of everyone's time. Be prepared for an interview with the recruiter, the COO, the CEO and the team members you'll be working with. The turnaround from offer to acceptance is short, so be prepared for that!
