Amazon Manager, Software Engineering interview questions

On-site interview in Seattle with six one-hour sessions (one of which was a lunch break). The questions seemed primarily designed to elicit alignment with Amazon's leadership principles. There was a technical interview given by a principal engineer, which seemed similar to what a senior engineer would expect. Additionally, there was an essay component to the interview.

Random email from recruiter that Amazon Alexa recommended me as a right candidate for the position with Alexa ML. Had an hour long chat with the recruiter followed by an hour long phone call with the hiring manager who seemed clueless about his own requirements and was constantly stumbling to explain his team's need in a coherent way. Very disappointing to see such poorly prepared interviewers at such reputed organizations with no understanding of their own needs or candidate's background.
