Google Chef De Projet interview questions

Referred by an employee for a very suitable position. Given my previous experience, skills and need the interview process was difficult to moderately difficult level. Initial phone screen followed by 4 onsite interviews, then 2 more phone intro/interview calls was my process. Took over all 45days to complete the entire process.

Was referred by a friend who worked at GOOG as a PM, the recruiter got in touch fairly quickly. Didn't have to go through a phone screen / behavorial interview, and went straight into the phone interview with a PM who asked how I might think about a mobile ad opportunity.
