I think Googling the question exactly and copy and pasting the answer would qualify as cheating.

(Disclaimer: I completed an internship at Amazon and accepted a second internship)

I dunno man. I'd much rather see a well understood vetted email validation(or whatever )copied from stack overflow than some thrown together hack in production code.

being able to look things up is a different skill than being able to understand and properly apply what you looked up. Or being able to understand what you are looking up and why.

That's very easily caught by googling candidates' answers.

There are definitely people who would hire an expert to pass the test for them if they could get away with it.

I have a friend who outsources his job to India. It's not "cheating".

There is cheating in online testing, however.
