This is incredible. If I knew I'd be working on things like this (as opposed to optimizing ad revenue or "user engagement" by A/B testing button copy), I'd possibly consider working at Meta.

At Meta you choose what team you want to work on during a 3 month “bootcamp” period, very different from Google, Amazon, etc. There’s enough teams solving hard distributed system problems that you’re guaranteed to never need to think about button copy

You can also be directly hired onto a team, skipping bootcamp (some roles).

you skip team selection, not bootcamp. every engineer and EM go through bootcamp

In good times, yes, there are more roles than bootcampers. In bad times (now) there are more bootcampers than roles...

Hm, the number of teams that work on these distributed systems is smaller than I think you believe exists at Meta, though I suppose it depends on the type of system being built. Even the internal post on this topic links to a note from last year that talks about the 3 teams in the core systems area that needs to work directly with PTP.

The vast majority of people will probably end up working on product-related team compared to infrastructure-related teams.

Oh, sure.
