A recruiter reached out a few days after I applied online, and a phone screen with a PM was scheduled. I am an experienced candidate (5 years of work experience, no MBA) but the person who interviewed me for the phone screen was an APM (associate PM) who recently graduated from business school. From the start, he had this "I'm better than you" attitude, and did not take my industry experience seriously. I think it would be better if Google matched candidates with interviewers of similar background. You'd avoid this situation where this MBA guy was trying to "flex" on me the whole time and make me feel inferior. He asked me two questions. First was a product design question, which I nailed. He even said at the end that this was good. The second question was a brain teaser. I didn't get it right away, but caught myself going down the wrong track and then gave the correct answer. Then he decided to extend the problem space to infinite size and asked me to come up with a generic solution to the brain teaser. This is where I was stuck and wasn't able to come up with the optimal solution. Although at the end, he said I did well in solving the original brain teaser, but didn't comment on the extended version.
