Fifteen years ago at Microsoft, most people worked ~40 hour weeks, there were shuttles between Seattle and Redmond, a good gym on campus, and (mostly) private offices.
You'd come into work at 9, wander off campus to a nearby restaurant with coworkers for a relaxing lunch at noon (granted, because the food in the cafeterias sucked and cost money), and after a bit of exercise or a nice game of racquetball at the gym, you'd go home at 6. Or if you were single and it was a weeknight, you might stay late in the office watching movies in a conference room and doing a bit of coding.
Of course, fifteen years ago, Google paid more and had a reputation as a place where the really smart people came to grow their careers, whereas Microsoft was sleepier and more middle-aged.
But it had "WLB" in spades.
