The recruiter didn't have enough common decency to turn on her camera. That along with the questions asked, flow, and her lack of energy from beginning to end made it clear that this was a waste of time. After it was over, I meant to send a follow-up email that I was no longer interested, but over the following week got the rejection email anyway so it all worked out. You usually want to put your best face forward when interviewing anyone getting to know your company, Neato didn't with this recruiter.
