I don't see where massive amounts of fraud have anything to do with basic human rights to privacy and being treated ethically. In fact, massive amounts of fraud is just a thing people say when they want to distract from something else that constitutes inexcusable corporate cultural behavior.

How does seeing the room a person is in prevent fraud? "I see you have a different room than the one I saw when I spied through your window, so I know you're lying about who you are"?

Surely seeing photographic identification would be a better way of detecting fraud than seeing someone's room?

That’s identification. It doesn’t account for other modes such as candidates having people “coach” them in real-time, either virtually or in the room. Yes, it absolutely does happen. The risk/reward of “cheating” a job interview is fantastic from the candidates perspective.

So what we're saying here, is that fraudsters aren't smart enough to figure out this measure is being introduced and work around it?
