Smooth and successful. Unfortunately Amazon (just like the other top companies) was not really hiring out of a real need. They were rather shopping around to see how would their current employees fit in the in the skill set offered in the market.

Amazon's hiring, at least in my experience, was a very well oiled machine. I went out into the market in April/May and not all the big companies were as pleasant to interact with. The process was really good, and efficient – I got answers and decisions quickly. The interviewers helped improve on my solution and were constructive in their feedback.
