Years ago when I was starting to interview for Uber in Europe I went through some data structure exercise which I failed at horribly. When I asked the hiring manager whether this was representative of the job, because I would probably not be good at it they said "no", and to follow up, when I asked why we did it they said, "in the next round my colleagues in the USA are going to ask you something similar".

I guess this wasn't entirely without sense but sort of seemed to be missing the point.
