Google Associate PM interview questions

There were two phone interviews that asked basic questions that tested my knowledge of basic math principles, logic and application of Google products to solve everyday problems. Each interview lasted about 40 mins. The interviewers were polite and courteous

Employee referral then got phone call interview with an APM. First disappointment, my interviewer was 15 minutes late. I thought that the interview duration will be extended to catch up the 15 minutes, but It wasn't unfortunately. So at the end, I had no more than 5 question in total, without really a relationship or a backbone behind. We start from A, jump to L, go back to B and finish with Z. When interviewing, I usually have the feeling that I'm building something to showcase my knowledge, not just jumping from unrelated question to another. I also felt that my interviewer was running the interview in a "machinal" or "robotic" way. I felt that he wasn't really caring that much about what I had to say and I felt the conversation always one sided. Last, I found the question completely irrelevant. I had one real question about PMs, which I thought will be the main topic of our call!
