The interviewer gave me a brief overview of the company before asking obscure technical questions about Amazon Web Services that had no relevance to my background on my resume as a java software developer. I was expected to know the nitty gritty details about how AWS works instead of how I used it to meet our customer's needs. He was also condescending when I didn't know the answer to a question he asked. It was clearly a phone screen because the interviewer was just going down a list of questions and made no attempt to drive the interview like a conversation or ask me about my experience.
