Google Chef De Projet interview questions

Referred in by a friend. Some informal preliminary interviews with members of team. Then in-house recruiter set up a day of 5 interviews on-site in Mountain View (some were with remote members of team via teleconference). One thing I noticed about the interviews was that they asked questions and just let me do most of the talking. Was much more them collecting information from me and my answers than conversational.

The process took roughly 4 months end to end. A friend recommended me internally for a role which I got through to an interview. The first round was a phone interview with some basic questions why do you want to work here etc. After this had a second phone interview and was invited to a 4 hour on site interview day. When I got to the Google office I was told that the role had been changed to something completely different and that the hiring manager did this because he felt too many people applied for the role I applied for. After a discussion with him he made it clear that it was not a test and that the role had been changed to something I couldn't do and therefore probably wouldn't get the job. He then gave me the option to continue with the interviews but it would only be to get to know the company a bit better...
