My wife did one of these for a class. A real person in a pre-recorded video asked her questions. Then she hit “record” and gave her response by video. After completing the 10 questions (she could hit playback to review and do as many “takes” as she needed to get it right), she hit submit. Voila! On to the “recruiter” (this ended up being her teacher, who coached her in advance of the real, face-to-face interviews).
I’m not opposed to using this approach for a first round…but feel like there should be some direct interaction in the process before hiring.
