I already try to get transcripts/notes from interrogations^H^H^H^H^H^H^H^H^H^H^H^H^Hinterviews for this very reason. 90% of the information in 1% of the time (for a live interview, with hassle) or 10% of the time (for watching a recorded video/audio).
It's actually sort of good for marginal candidates, though -- if it costs me much less to interview 100 vs. 10 people, I might look over a lot of people who would get rejected at an even earlier stage otherwise.
