Overall picture: Google recognizes it's a large company that has an extreme diversity of teams with idiosyncratic goals and personalities, and doesn't prescribe _anything_

Dollars to doughnuts, there's multiple teams doing extremely prescriptive Agile, but I've never seen one in 3 years in a 2,000 employee office.

By far the most organized team I've been on merely kept track of bugs using an internal web app that renders bugs from the internal bug tracker as post-it notes arranged in columns, with each column representing a bug status (ex. assigned/started work/code in review/done).

This alone caused a ton of grumbling, meanwhile I'm sitting there gobsmacked that Scrum and Agile aren't proper nouns that everyone has highly detailed opinions on.

The teams I have worked on at Google have no process on a team level. We just copied the mandatory things like code reviews and automated testing, other than that people just figure out what to do on their own. The main motivation people have to work is so they have something nice to put in their biannual performance evaluation, so everyone is very eager to try to solve problems. Of course if you bite off more than you can chew and totally fail then you have nothing, so people try to pick sensible projects which will actually succeed.
