I went to a job interview last year (at a trendy SF-type start-up) during which the interviewer boasted, "We have amazing catered dinners every night at 7pm." To some, that may sound like a perk. To me, it sounded like late nights. That was actually the red-flag that convinced me I was a bad fit for their culture (despite otherwise having really complementary domain knowledge/skills).

Though I'm not sure how much of that anecdote applies to Google, it's still worth noting that not all perks are interpreted as such by employees.
