Google Project Manager interview questions

After several reschedules, i finally got my interview that was timed at 6.30am for me. so no coffee. it was a fun interview. several years earlier i had applied and rejected but i was able to get feedback then as to what went wrong, but i was self-conscious of making the same mistake (being scattered in my thought process). I did prepare with youtube mock-interviews, and a few kindle books. The interviewer was nice and got on with him, and i felt i did an ok job, but wish i had more time to go back to some aspects that i thought were important (and it turned out crucially it was)

I went through a initial round with the HR and scheduled for 1 hour initial phone screening. He was a product manager who called started asking the right away on what my favorite product. It could be anything I use in day-to-day life. Then, he asked to define the problem statement and asked to go through fundamental stages of defining a problem. It was very basic actually that you end up being nervous. The interviewer were very straightforward and only wanted to hear particular answers.
