Google PM interview questions

A recruiter contact me through LinkedIn and set up an initial phone call Then a follow-up HR representative contact me by email and scheduled a phone interview with a current Project Manager. The interview went fine, but I did not continue to the next step. No feedback what so ever, even when I asked HR and an internal contact I know. However, Google was not ashamed to send me an email a few days later asking for my feedback... Of course I declined based on reciprocity...

I posted my resume on a job-seeking website and I were contacted by someone from a HR company. They asked me whether I wanted to work for Google and I said yes. Then they arranged a video conference because the people who interviewed me was in Japan (I were in Singapore at the moment). The interview went quite well and I were asked about my background, skills, etc.
