Google PM Intern interview questions

There were two rounds of interviews two weeks apart. Each round had two 45 minute interviews over google meet. Each was done with a PM at Google. After the first round I heard pretty soon after that I got the second. 3 were product interviews and 1 one was technical.

Some of the engineers and PMs seem knowledgeable but have no actual communication or interviewing skills. It was challenging to figure out what he was even asking and assessing for. He seemed to be making up questions and scenarios as we went through the interview.
