Amazon Software Engineer Front End interview questions

On Linkedin, a recruiter approached me about this role. I was sent the interview preparation materials which was everything I learned from my bachelors in Computer Science to more than 10 years experience in the IT field. The interview was clueless about my resume or background. He didn't like walking him through the solution as per AWS advice to never start a solution/coding without explaining your thoughts. He wasn't even part of the team that I am interviewing for. He couldn't answer a question about the team that I am interviewing for. So disappointing.

First of all, ask my tech background from my resume. The project that I work on, the technology that I work on Give me a technical question to solve. After solving it, ask me to do some optimization.
