Amazon Software Development Engineer interview questions

I had an online interview that was roughly 1 hour long. I was first asked two behavioral questions relating to a previous internship and then asked a technical question about data structures.

1st round relatively easy, 2nd round more challenging (on-site, close to the waterfront skytrain stn). 1st round was a online coding test for 90 min (2 questions with analysis), about easy-medium difficulty. 2nd interview was a 5-rounder lasting 5 hours with 1-hour lunch break. A LOT of behavioral questions, I mean A LOT. "Give an example where you.....". In later rounds I was getting numb answering these questions so I started to gaie answers like "I don't have such examples..." Algorithms Qs were around medium-difficult levels. I didn't prepare well so the outcome was expected. One thing I noticed was almost all the interviewers were typing like crazy during the process. They were very good at multi-tasking though, because even with all the typing they were still following what I was talking about or writing on the white-board. So I guess they were probably super-busy or maybe had to do a lot of interviews...
