An Amazon interviewer once gave me the word ladder problem unmodified. I am not a recent college grad, and I don't encounter a lot of interesting algorithm problems in my work, so I had prepared by working through some leetcode problems. But I had worked through only "easy" and some "medium" problems because I had the impression they didn't ask the harder ones. I was able to recognize it as a BFS graph problem and gave the time complexity (and space complexity, IIRC), but I did not finish it on the whiteboard. Live and learn. Maybe I'll have another go in six months. Can't argue with the money and the resume cred.
