Headhunter reached out to me for NDE job interview at Seattle amazon. It took about 2 weeks to schedule a phone interview. Interview was nice. they dont ask any trivia question, instead he asked me what I have done so far and the asked me question based on designs, like why you chose to use ibgp and not ospf ? etc etc, so thoroughly understand your own design so you can answer those questions. Also Amazon principles are must and they may ask a variation of it, so understand them well and prepare a example for each of that. Also at least have 1 year of good programming language experience before you apply for this role. Just basic understanding of python or ansible won't be suffice.
