Google Senior Software Developer interview questions

I submitted a resume online to Google/Sketchup Boulder office on Pearl Street. I did an initial phone screening discussing past work history and some development and programming questions that were somewhat perfunctory. I came for in in person interview. The office is a very stylish loft above retail on Pearl Street, basically the startup with too much money dream-office. Huge double monitors, fast workstations, slack dress code, unused foosball table etc... Lunch was catered in daily apparently from a posh catering company and the food was excellent. I interviewed with one of the sketchup founders who clearly thought very highly of himself. The position was for implementing extensions to the javascript interpreter scripting engine for sketchup.

I was contacted through linkedin by a recruiter and after giving them a few references from friends who work at google, i was able to bypass phone screen. My friends said they received a form that they filled out. But even than, I was passed around to at least 4 different recruiters by the time I was actually onsite. I was interviewed by 6 people, plus the lunch person that had no say on the process. 3 of the interviewers asked me to code on a white board, and 3 did not. I thought that was odd, I had expected all of them to ask me to code. I made a mistake of making google my first interview in 7 years so I made silly errors. Overall it wasn't as dreadful as others described it.
