When I was being interviewed by Google they didn't ask me any questions 
like this one, but your generalized questions would be very much more the 
sort of thing they ask.

They are very keen on whiteboard coding questions so I wouldn't have been 
at all suprised if they had asked me "given two hourglasses of m and n 
minutes and a desired time t minutes write a function that would take the 
above as arguments and print out the required steps to reach the desired 
time."
