An initial technical phone-screening with an amazon SDE that, after a general introduction, comprised of a coding (in-browser) exercise, followed by basic troubleshooting,network and algorithm questions.
I was the contacted by the HR recruiter for the on-site interviews.
The on-site was comprised of 5 interviews, each 45 minutes long, with a food break in the middle, where a technical staff member takes you to eat out and during which you can ask questions about the general work-life environment at amazon. This part is off-the-track and the person you're eating will not be looped into the decision to hire you or not based on the eat-out discussions.
The on-site interviews were related to coding and algorithms, networking, linux, troubleshooting and a HR interview (half in romanian, half in english).
The people were very friendly and clarification questions were promptly answered.
