I only met with recruiter but process was explained to include a detailed interviewing process where a presentation is required followed by series of interviews in a single day. Decision is made in ~3 weeks.

They made me create a 50 page presentation about me, why I'm a good fit for the job, etc. I had to go down to Mountain View and present for them. Once I got down there, while waiting in the lobby, I heard the person that was going to be interviewing me say "I don't know why we're bringing all these people in for the interview when we have no intention of hiring them". So after taking off half a day of work, buying a whole new wardrobe, including shoes and ruining my whole weekend to create an entire presentation, I found out that the whole thing was a farce. So disrespectful!
