An excruciatingly long process from start to finish. From multiple telephone interviews to a full-day of interviews at Google's London offices. The full-day of interviews could have been easily conducted within an hour as the questions presented were all roughly along the same theme. My first interview was conducted by a guy who really didn't want to be there. That unfortunately set the tone for the rest of the day. The arrogance of the "director" interview (third interview) put me off Google altogether, so I was looking to leave fairly quickly after that. Playing on your phone and laptop in a 1:1 interview is rude, no matter who you are. As a contractor, that day of interviews cost me over £600 - the least you could do was read my CV and listen to what I had to say. In total, I would estimate the process took around 14 hours of my time over 5 months. Overall I dodged a bullet by not working there, but blown away by the organisation.
