Not gonna break the NDA, but few points that I think may help: - once you're thru to the onsite, revise and refresh your knowledge. across the board, make sure you can comfortable refer to your career and experience. - get a good night sleep, especially if they fly you in! No redbulls and obsessing overnight, it's too late at this stage... - know what you're talking about! this is very important and helps if you're actually good at what you do. - pay attention thru the interviewing process, listen and think! - relax, well try to relax. Amazon has very high standards and the interview process is difficult! - do not overdose on caffeine! Recommended amount of caffeine is usually 400 mg per day for healthy adults. That's like 2-3 coffees MAX! Lastly, it can be done! People who interview you sat in "your" chair once... you got this!
