At these companies successful senior folks don't sit around waiting to get told what they're working on. It's their job to pick or start impactful projects in line with their org goals. If they're right they get rewarded but if they're not, they don't.
If you're junior it won't really matter. If you're senior, and you're sitting there hoping your manager is going to give you something meaty you're not long for that company - because that is not your job.
This was my experience at two FAANGs and also at one non-FAANG company over the last 10 years. Maybe it's different at the ones I didn't work at, but your snark is neither useful nor interesting. It also gives folks considering FAANGs here a false impression of what working there is actually like.
As a senior SWE at Amazon I had the autonomy to do this sort of thing as soon as the several years worth of work my team had planned was done. Half the senior SWEs at a big job board that calls itself a tech company are concerned with migrating everything to per-table microservices that expose endpoints that do exactly the SQL queries other services used to do directly. Thanks for your report of your different experience in a different org. I'll try not to give people a false impression by posting about mine.
