Applied online, was given problems to solve in a coding challenge. Wasn't particularly hard. The questions were relatively straightforward, but I made a basic mistake and got stuck on a bug.
I applied online. The process took 4 weeks. I interviewed at Amazon in Jan 2018

Simple and straight-forward. In the second online coding round, I was given a problem involving a process that I had never heard of before and that was not explained well in the question. As a result it took me half the allotted time to research and figure out what it was before I could begin solving the problem.
