It really did just feel like grad school with better funding. For me it lasted until around 2014 (wow, 10 years ago) when a director stole my ideas and bad-mouthed me to a bunch of senior folks. I hung on a bit longer (working for a close friend of the author of this FAQ on 3d printing and making stuff) and then a couple stints with ML hardware, before I finally concluded that the company was well on its way to enhittifying everything it did.
Sundar is sort of the complete opposite of this. He wants a large pool of completely anonymous programmers and a small number of directors who know how to turn those programmers into growth products, but those directors don't have a clue. For example, with gChat, one day the head of chat told TGIF that chat was changing, that japanese teen girls were the primary target, and they wanted emojis. He didn't even get that there was this enormous number of professional workers using gmail/gchat/gcal/gdocs and that by fucking up the product, he lost their trust.
Oh well. Sundar is why we can't have nice things.
