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
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.
