Do people at google actually work 11-4 like it says in the article?
Google is a giant company, so surely somewhere there are some people who behave this way—-among a hundred thousand employees and hundreds of groups you will find at little bit of everything. But in the groups I have worked for, solid full days are the norm, and somewhat rarely you have to really dig in and work a bit more, and even more rarely, you have so much slack that you can go hone early. But generally people nearly always put in full days.
