Amazon Software Engineer interview questions

Contacted over phone, using a shared text editor so that I could see problems the interviewer put up and he could see my code to solve them. Overall fairly straightforward, though we were a little rushed towards the end so I wasn't as happy with my second solution as I could have been if I had the full time.

First take a few online programming questions, got called back in less than a week to schedule on site interview, interview roughly about after 4 weeks, 4 interviews each an hour long with breaks, each interview was taken by a single interviewer. entire process was felt easy, interviewers were very nice and warm
