If this video call gives the interviewee a final opportunity to express their thoughts and has the potential to change the outcome, then I think it still has positive value. However, as mentioned in the article, most people feel very awkward and have nothing to say during this meeting, which is simply torturous. In that case, I think it would be better to replace the video conference with an email, after all, if you don't allow the possibility of changing the outcome, why not make it more comfortable for both parties?
