well, as i said in another comment as well, if your questions can be answered by a quick web search, then maybe they should think about how you actually work; you web search a LOT. ask questions that filter on something less obvious
there are still in person stages; this is just a filter for them. it's not like it's the only data you get to hire or not hire someone
Why is everyone assuming that a cheater will only do a "quick web search"? You could call someone to walk you through it over Skype, or get a person to solve it over remote desktop, or even have a friend sit in and do it for you, etc.
These are the cases where monitoring is needed. Whether or not what Amazon is doing is actually effective is another issue entirely. All I'm saying is that it's not as huge a deal as a lot of people on this thread are making it out to be.
