Amazon Non Software Development Engineer interview questions

Got an email from a recruiter for an initial phone screen, but when we finally spoke, he said the role required at least 1 year of experience, but the Job Posting explicitly stated that they were looking for someone with either a Bachelor's degree in Computer Science, which I had, OR 1+ years of equivalent experience in software development. Recruiter was unprepared and highly unprofessional.

The interview was a typical Amazon interview however the interviewer opted to make it a full coding interview instead of coding + behavioural questions. He kept asking to solve one coding challenge after another until the time was up.
