I've always found Skype/Facetime/etc. to be off-putting - if only because by looking at the person I'm talking to forces me to appear to look under them (looking at the screen vs looking the camera). During interviews, I make the conscious effort to look at the camera so as to present a more normal eye contact for my viewer, but this undercuts my ability to read their physical responses. If I had true-to-size representation of a person, either in VR or with a 2D screen, that allowed me to use natural eye contact and body language I would use it far more often.
