Google Produktmanager interview questions

Applied online for Product Mgr role in the Hyderabad office and 3 weeks or so later got an email from HR., by when I returned to the US. The HR person got the interview date mixed up so I received a call a day earlier than expected. I mentioned to the interview about the mix up and he was polite and rescheduled it for the correct day. Next day, a different person called (this time from India), he was on a speaker phone typing away on his PC while I was talking and the line just wasn't clear. Overall, good thought provoking questions and although I felt my answers were good, didn;t make it.

2 phone interviews. First one asked no questions about my background, only design brainstorming questions: -How would you design a refrigerator for someone who is visual impaired? -What could the Microsoft Surface table be used for? -How would you improve an in car GPS system? -Is Starbucks instant coffee (via) good or bad for the company? Second interview got into more technical areas. Asked about background and asked what I would be "known for" at the company.
