"The point of buying the server wasn’t to save money, it was to build something cool." In the end, this is always the real answer - one that I'm sure we can all agree is the 'correct' one too.
Reading through all the responses...My personal take on what I've been reading.
The amount of cheating that I ( and my fellow professors ) have seen during these past few years has absolutely exploded (in a way that is beyond belief, and I've been doing this for a while).
The techniques others have outlined/alluded to ( camera off, a big life event just happened, looking off camera, noise, etc ) are all things that I've been seeing. And whilst this is nothing to be lauded, after all how many vectors are there, I do think that perhaps a solution is looking towards academics. (just saying...)
As I see it, the hurt is going to come from more hoops expected, as any burdens are always passed down to the individual. In in an ideal world, companies would actually read/think/analyze all the data/metadata they already have; however, we don't live in this world. And the individual's going to have to spell everything out in gross detail.
Totally confused why folks are not understanding/believing what you've stated. I can attest, this is happening and at 'top' tier places. I can't tell you how spot on you are regarding the camera off strategy.
Happened with my partner, and have heard of this from a lot of friends. This is a real issue. It hurts 'real' candidates and everyone that takes time to be apart of the hiring process.
HR dept's are simply unable/ill-equipped to handle this new reality. Honestly, at larger org's this is really an upper management issue first and foremost, as HR dept's are sort of benefiting from these frauds. ( Before you go off on that last sentence, I did say 'sort of' - and I personally believe in 'you get what you incentivize'...so)
