I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon in Oct 2018
Interview
Read through articles online and YouTube videos prior to interview. Their internal recruiters were very helpful. Everything I read and what they told be was true. They are super heavy into the principals. A lot of prep need to lay out correlated stories. Good luck remembering all of them. Use the SAR (situation action result) method when discussing. This was full on behavioral interview questions.
Interview questions [1]
Question 1
Outside of leadership principals. their was quite a bit of technical discussion. At the end, I was advised that in these positions you need to have an AWS Solution Architect Pro Cert within first 90 days of hire. Even though it is not an engineer position AWS expects you to speak on all the topics with client and AWS teams. My advise is to ask recruiter about the need for a cert to gauge your readiness.
