I know they don’t do bootcamp any more, but Facebook were perfectly set up to move people between divisions by not hiring for specific roles, and doing team matching over orientation. It was a system that worked well, and being able to switch teams easily meant that people could jump from WhatsApp to Instagram to Ads with minimal friction.

In terms of numbers, definitely, but a phased rollout could work if it meant keeping services in KTLO, and moving people out gradually as you slow down internal hiring. Sadly, companies find it easier to just sack everyone, and then hire again in a few months.
