Google Associate Product Manager interview questions

I got contacted by an HR recruiter to set up a first phone interview with a PM, few days after an employee referred me. The interviewer had a non-technical background and 10+ years experience in a non-tech related company. The questions were fairly conventional: 1) Why do you want to join Google? 2) Design questions: - How would you design an ATM for elderly people? - How would you figure out whether there are any problems with the ATM design? - What is a Google product you love? Imagine you are responsible for one of its features, how would you monitor its use, and how to measure its success/ failure? 3) Market sizing questions: -How to monetize Google Maps? -How would you calculate the revenue from the ads on Google Maps? 4) Creativity questions: (took nearly 25 minutes, clearly the most important part for the interviewer) - Google is thinking of creating an all internet car, brainstorm some interesting use cases!
